What is Intelligent Document Processing (IDP)?
Intelligent Document Processing (IDP) is an AI-powered document processing technique that not just scans and captures structured, unstructured and semi-structured data, but also understands it deeply. It is a modern development in the realm of document processing, a field that has been evolving since the early 1900s with the advent of document OCR (Optical Character Recognition). The progress in technologies like machine learning, natural language processing, and computer vision has reached a level where they can be effectively employed in tasks such as classifying documents and extracting data. IDP leverages these AI technologies to automate and enhance document-related processes.
IDP stands out from conventional document processing due to its unique capabilities. It goes beyond mere recognition of words and characters, but rather interprets the meaning and context of the data. Thus, IDP does more than just capturing data – it provides valuable business insights and continuously enhances its performance by learning, which lessens the necessity for human involvement.
To understand the concept, let’s say you have a pile of letters that includes utility bills, personal letters, promotional flyers, and so on. Now, if you were to manually sort them, you’d have to open each envelope, read the content, decide what it is (e.g., a utility bill, a personal letter, or a promotional flyer), and then put it in the appropriate pile.
In the context of Intelligent Document Processing (IDP), it is as if you had a super-smart robot assistant to do this for you. This robot doesn’t just look at the envelope or the layout of the letter (which would be akin to older OCR technologies), it actually ‘reads’ and ‘understands’ the content of each letter. It knows that a letter with “Dear Customer, your electricity usage this month was…” is a utility bill, and a letter that starts with “Hi, How are you?” is a personal letter.
So, the robot, like IDP, can sort the letters into the right piles, but it does it much faster and without any manual effort on your part. Plus, it can handle thousands of letters in the time it takes you to sort through a handful. That’s the power of IDP in a real-life context!
Different sectors are at various stages of integrating IDP. For instance, lenders who supported the Paycheck Protection Program (PPP) have extensively used IDP AI to expedite the review of pandemic loan applications. On the other hand, many mortgage lenders lag in adopting IDP and still rely heavily on manual document processing.
One of the significant advantages of IDP is its scalability. Whether you are dealing with a small number of documents or a vast processing operation, IDP can adapt and handle the task efficiently. It drastically reduces the workforce requirements for managing and processing documents. However, human involvement is still necessary to some degree.
While both automated and intelligent document processing belongs to the same technological family, they exhibit unique characteristics that set them apart.

The actual differences may vary based on the specific ADP and IDP solutions being compared. Each solution might have its own unique features and capabilities beyond the general differences listed above.
What can IDP do?
At the heart of Intelligent Document Processing (IDP) lies the capability to automate the extraction of data from complex, unstructured documents – a task that has traditionally been labor-intensive and required specialized human expertise. IDP systems leverage sophisticated technologies like natural language processing, optical character recognition (OCR), and machine learning to understand and extract relevant information from these documents.
Firstly, OCR technology digitizes documents, converting images and handwriting into machine-readable text. However, OCR alone isn’t sufficient for extracting meaningful information, especially from unstructured data like emails, invoices, contracts, etc. This is where NLP and ML come in.
NLP allows the IDP system to understand the context and semantics of the text, much like a human would. It can sometimes understand language patterns, interpret meanings, and even understand the sentiment. Coupled with ML, the system can continuously learn from its experiences, improving its accuracy over time.
Machine learning algorithms are trained on large datasets to recognize specific data points in a document, like names, dates, amounts, etc. and extract them accurately. Whether rule-based or leveraging advanced deep learning, these algorithms possess the ability to comprehend and extract valuable information from highly complex and varied document structures.
This advanced data extraction capability streamlines the process and enhances the accuracy and efficiency of data entry, reducing errors associated with manual data handling.
Document classification and categorization
A crucial feature of IDP is its ability to classify and categorize documents automatically. Advanced machine learning algorithms and natural language processing techniques power this ability.
The first step in the classification process involves using Optical Character Recognition (OCR) to convert the text present in the documents into a machine-readable format. Once the text data is available, Machine Learning (ML) models, often supervised models trained on labeled datasets, are used to classify the documents. These ML models may use a variety of features to classify documents, such as the presence of certain words or phrases, the structure of the document, or other identifiable patterns.
In addition, NLP techniques can be employed to understand the context of the document, which can further enhance the classification process. For instance, semantic analysis, a subset of NLP, can help understand the meaning of the text and classify it accordingly.
For scenarios where multiple documents are present in a single image or file, advanced IDP systems use segmentation techniques to separate each document before classifying them. Computer vision algorithms often guide this process, which can identify boundaries and structures within the image to segment different documents accurately.
Once documents are appropriately classified and categorized, they can be routed to specific workflows or processes. This automated sorting and routing significantly reduces the document processing time and the chances of human error or bottleneck in processing, making IDP a highly efficient solution for managing large volumes of varied documents.
IDP systems significantly enhance data quality and accuracy through the process of data validation. This process is facilitated by a combination of advanced algorithms and AI technologies, ensuring the extracted data is reliable and ready for further processing or analysis.
The data validation process in IDP can be broadly divided into several steps. First, once the data is extracted from a document, it is initially checked for completeness and consistency. This involves ensuring that all necessary fields have been captured and the extracted data adheres to the expected format or pattern.
Next, advanced AI algorithms cross-verify the extracted data against predefined business rules. These business rules can include data type restrictions, value range constraints, or specific business logic requirements. For instance, an invoice date shouldn’t be in the future or an order number should follow a specific pattern. The extracted data is validated against these rules to ensure its accuracy and relevance.
In addition to business rules, IDP can leverage machine learning and natural language processing techniques to compare the extracted data with information from other documents or sources. For example, it can cross-check the details of an invoice with the corresponding purchase order to ensure consistency.
Moreover, IDP systems can utilize external databases or data sources for validation, confirming the accuracy of the extracted data against trusted third-party information.
In the event that the extracted data fails the validation checks, the specific data fields can be flagged for manual review or correction. This ensures that inaccurate or unreliable data doesn’t progress further into business processes.
By implementing these techniques, IDP significantly improves data quality, reduces the risk of errors, and ensures the data’s reliability, ultimately leading to more accurate business insights and decision-making.
Intelligence and insights
Intelligent Document Processing (IDP) extends beyond mere data extraction and validation. It plays a pivotal role in converting raw data into actionable intelligence and insights, enabling businesses to make data-driven decisions.
Once the data is extracted and validated, IDP systems employ various AI technologies such as machine learning, natural language processing, and text analytics to analyze and interpret the data. Here is how:
- Semantic analysis: Using NLP, IDP can understand the context and semantics of the extracted data. It can recognize patterns, trends and anomalies in the data, providing a deeper understanding of the information contained in the documents.
- Predictive analysis: Leveraging ML algorithms, IDP can predict future trends or behaviors based on the analyzed data. For instance, it can forecast customer behavior, market trends, or potential risks, helping businesses be proactive rather than reactive.
- Sentiment analysis: This is particularly useful for customer-facing businesses. IDP can assess sentiments from customer communications or feedback, helping to improve customer experience and satisfaction.
- Data visualization: IDP can present the analyzed data in intuitive visual formats like graphs, charts, and dashboards, making it easier for decision-makers to comprehend complex data and derive insights.
- Integration with business intelligence tools: IDP systems can seamlessly integrate with existing Business Intelligence (BI) tools, feeding them with high-quality, structured data, enhancing the accuracy and reliability of business reports and analytics.
With IDP, businesses can transform unstructured data from their documents into strategic insights. This not only improves operational efficiency but also drives innovation and growth. However, the specific analytical capabilities can vary among IDP systems, so it’s crucial to clarify what functionalities a particular system offers before implementation.
How IDP works: The detailed workflow
IDP employs a sophisticated workflow that seamlessly combines various technologies to automate the process of data extraction and analysis from complex, unstructured documents. This workflow significantly streamlines document management and allows businesses to access and utilize their data more effectively.
The IDP workflow commences with the capture of information from paper-based documents. Specialized scanning devices are used to transform these physical documents into digital formats. These digital documents then serve as the input for the IDP system.
Once the documents are digitized, the IDP system employs computer vision algorithms to recognize and understand the layout of different document types. These algorithms are highly versatile and can effectively process scanned images, PDF files, and a plethora of digital and paper-based file types.
The next stage in the IDP workflow involves natural language processing which is capable of identifying characters, symbols, letters, and numbers from paragraphs, tables, or unstructured text within the documents. This identification process, known as Optical Character Recognition (OCR), is further enhanced by employing techniques such as named entity recognition, sentiment analysis, and feature-based tagging. The result is a highly accurate interpretation of the information contained in the documents, with accuracy rates often exceeding 99%.
Once the information is successfully read, it is then transferred into content management systems. This process allows the data to be easily accessed, analyzed, and utilized for a variety of business applications.
With this introductory understanding of how IDP works, let’s delve deeper and understand the key steps in the IDP workflow:
Step 1: Preprocessing of document
In IDP, data extraction starts with Optical Character Recognition (OCR). When a document enters the IDP system, it begins with a step known as document preprocessing. The effectiveness of OCR heavily relies on its ability to distinguish characters or words from the document’s background accurately. There are a few key techniques used in this initial phase:
- Binarization: Binarization converts a colored image into black and white pixels with black (pixel value = 0) and white (pixel value = 256). The goal here is to clearly distinguish between the text characters (black pixels) and the background (white pixels).
- Deskewing: The resulting image may be slightly tilted horizontally during scanning. This misalignment isn’t ideal for OCR, so techniques like the Projection Profile method, Hough Transformation method, and the Topline method are employed for correcting this skew.
- Noise removal: This step eliminates any small, unwanted dots or patches. This cleanup is essential to prevent OCR from mistaking these elements for actual characters.
Step 2 – Document classification
The classification of documents within the IDP workflow unfolds in three stages:
- Format identification: The system first determines the file format of the document. It discerns whether the document is a PDF, JPG, PNG, TIFF, or any other supported file format.
- Structure recognition: Next, the IDP solution distinguishes between structured, semi-structured, and unstructured documents. Structured documents follow a consistent template and layout. On the other hand, semi-structured documents have some degree of structure but can contain similar information at varying locations within the document. For instance, an invoice, which is a semi-structured document, might have the vendor’s address positioned differently across various invoices. To make sense of such data, the IDP solution requires a contextual understanding of the document and its content. Unstructured documents have minimal structure, yet they often contain critical data that needs to be extracted. For example, contracts are usually unstructured, with certain values such as dates or email addresses not being clearly identified.
- Document type determination: The final step in document classification involves identifying the type of document, i.e., identifying whether it’s an invoice, bank statement, tax document, shipping label, or some other form. The IDP solution’s success in accurately identifying and routing a document type for data extraction depends largely on the data it has been trained on.

Step 3 – Data extraction
The extraction of data within the IDP workflow typically consists of two main components:
i) Extraction of key-value pairs: This involves pulling out the values that correspond to distinct key identifiers within a document.
ii) Table extraction: This process involves extracting line items organized in a tabular format.
Several methods are employed to accomplish these tasks:
OCR (Optical Character Recognition): OCR constitutes the initial phase of data extraction. While this step is crucial, certain errors can occur during OCR, such as:
- Word detection error occurs when the system fails to identify a text block in the image, often due to poor image quality.
- Word segmentation error: This happens when a word is interpreted incorrectly due to misidentification of interword spaces, varying text alignments, and spacing issues.
- Character segmentation error: This refers to the system’s inability to detect single characters within a segmented word, a common issue with cursive or connected alphabets.
- Character recognition error occurs when the system fails to correctly identify a character within a bounded character image. Techniques like dictionary look-up, k-mer, and n-gram language models can help rectify these errors.
Rule-based extraction: Rule-based models are effective for structured and semi-structured documents. They can identify key-value pairs or line items by referencing positions within a document. Approaches like Named-Entity Recognition and the n-gram model are useful for identifying values associated with key identifiers. For instance, regardless of the placement of the invoice number in an invoice, the model searches for a set of strings adjacent to “Invoice Number” or “Invoice No.”
Learning-based approach: Deep learning and machine learning hybrid data extraction techniques require supervised or unsupervised learning for training their models. Their accuracy rate and confidence score measure the efficiency of these models. As the volume of processed documents increases and the models receive more training and feedback, their accuracy improves. For instance, an ML-based model could be used in conjunction with a template-based OCR system to improve accuracy. Simple OCR correction methods combined with context-based natural language processing can enhance the quality and precision of extracted data.
Step 4 – Data validation
Data validation is a crucial stage in the IDP workflow, focusing on verifying and assuring data accuracy. This stage leverages advanced algorithms and pre-established rules to identify any discrepancies or anomalies in the extracted data.
Several techniques can be used in this process:
- Rule-based validation: This approach applies specific rules to the data. For instance, an invoice’s ‘total payable amount’ should match the sum of the ‘subtotal’ and ‘tax payable’. If there’s a mismatch, the system flags the document for review.
- Cross-document verification: This technique involves comparing the extracted data against other relevant documents or data sources. For instance, the system could cross-check the extracted invoice amount against a corresponding purchase order or contract agreement.
- Machine learning validation: Machine learning models trained on historical data can predict expected data values and flag anomalies. These models can be especially useful when dealing with large data volumes, providing an additional layer of validation to the process.
- External database validation: For some types of data, validating against an external database or API may be possible. For instance, a system could validate address data against a postal address database or a company name against a business registry.
By combining these approaches, IDP systems can ensure high levels of data accuracy, reducing the risk of errors propagating downstream in business processes. However, it’s essential to note that data validation is an ongoing process, requiring regular review and updates to rules and models as business requirements and data structures evolve.
Step 5 – Enhanced validation
Enhanced validation in the IDP process can be significantly bolstered with the use of Robotic Process Automation (RPA). RPA, with its ability to automate repetitive, rule-based tasks, is particularly suited for streamlining data validation.
Data is initially extracted from various documents using IDP technologies like OCR and ML in an IDP workflow. This extracted data can contain a variety of details such as names, dates, account numbers, transaction specifics, among others. Following the extraction, the data undergoes an initial validation where basic validation rules are applied. This could include checking if all necessary fields have been populated, confirming that numerical fields contain actual numbers, or validating that dates conform to the expected format.
At this juncture, RPA can be employed for a deeper, enhanced level of validation. For instance, RPA can cross-verify the extracted data with information from other systems or databases. If a document contains a customer’s name and account number, an RPA bot could access the customer database to validate that the name and account number correspond correctly. While this task would be labor-intensive and time-consuming for a human to perform manually, an RPA bot can quickly and accurately carry it out.
In the event of a discrepancy identified during the RPA validation process, the bot can flag the document for review. This allows a human operator to inspect the document and rectify any errors manually. This integration of human judgment ensures that the validation process remains both efficient and precise.
Moreover, the combined use of RPA and ML can facilitate an environment of continuous learning. If errors are identified and corrected during the validation process, this information can be fed back into the machine learning model, thereby enhancing its accuracy over time. Consequently, by integrating RPA into the IDP workflow, organizations can significantly elevate their data validation processes’ accuracy and efficiency, leading to notable time and cost savings and improved data quality.
Step 6 – Human review
While IDP aims to achieve complete automation, it’s important to acknowledge that no data extraction model can guarantee 100% accuracy. Thus, the IDP workflow incorporates an essential human element – the human-in-the-loop. This involves manual review and validation of any documents that have been flagged for potential inaccuracies during the extraction process.
This human intervention serves two critical purposes. First, it ensures that the final data output is as accurate as possible, reinforcing the reliability of the IDP system. Second, it contributes to the supervised learning of the model, gradually enhancing its accuracy. This continuous process cycle of processing, reviewing, and learning helps the model evolve over time, increasing its performance as more documents are processed.
The processed data is ready to be integrated into the user’s workflow upon successful extraction and validation. The IDP system has the flexibility to push this data to a database or export it in various formats to suit the user’s needs. Be it JSON, XML, PDF, or any other format, IDP workflows offer the versatility to convert documents into a format that best fits the user’s system or requirement.
The key components of intelligent document processing
Optical Character Recognition (OCR)
Optical Character Recognition, commonly referred to as OCR, is a fundamental technology used in IDP. It’s the technology that enables computers to understand and convert different types of documents, such as scanned paper documents, PDF files, or images captured by a digital camera, into editable and searchable data.
At its core, OCR technology analyzes the shapes and patterns of an image’s dark and light areas to identify each character. Advanced OCR systems can recognize multiple fonts and languages, making them highly versatile.
In the context of IDP, OCR is the first step in the process of extracting valuable data from unstructured documents. It ‘reads’ the text from the document and converts it into a format that can be processed and understood by the rest of the IDP system. Without OCR, the system would not be able to ‘see’ the text in the document, making further processing impossible.
However, OCR is not infallible and is subject to errors due to poor image quality, unusual fonts, or complex layouts. To overcome these challenges, IDP systems employ advanced techniques such as image pre-processing to improve the quality of the input images, or machine learning to improve the OCR’s ability to recognize and interpret text correctly.
Another layer of complexity in OCR within IDP comes from the need to understand and process not just individual characters but also how those characters form words, sentences, and ultimately, meaningful content. This is where NLP comes in. NLP is a field of AI that focuses on the interaction between computers and humans through natural language. In conjunction with OCR, NLP enables IDP systems to ‘understand’ the content in the documents, making it possible to extract not just raw data, but valuable, actionable information.
Machine learning and artificial intelligence
Machine learning and artificial intelligence serve as the critical engines powering intelligent document processing. They help transform unstructured data into structured information and extract meaningful insights from it.
Machine learning: In the context of IDP, ML algorithms learn from training data, which includes a variety of documents and the correct output for each document. Over time, these algorithms ‘learn’ to recognize patterns and structures in the documents and improve their ability to extract the correct information.
Two main types of ML are used in IDP: supervised learning and unsupervised learning. In supervised learning, the algorithm is trained on a labeled dataset, where each document is paired with the correct output. On the other hand, unsupervised learning does not require labeled data; instead, the algorithm identifies patterns and structures in the data on its own.
ML plays a significant role in several stages of the IDP workflow, including document classification, data extraction and data validation. For example, ML algorithms can learn to classify different types of documents based on their content and structure, extract relevant information from these documents and validate the extracted data based on predefined rules.
Artificial intelligence: In the context of IDP, AI is the overarching technology that brings together OCR, ML, and other technologies to create systems capable of processing documents intelligently.
A key aspect of AI in IDP is NLP, which allows the system to understand, interpret, and generate human language. NLP enables IDP solutions to handle more complex tasks, such as understanding the context of information in a document, recognizing entities, and even understanding sentiments. This is particularly important when dealing with unstructured documents, where information is not neatly organized in tables or forms.
AI also enables IDP systems to improve over time. As more documents are processed, the system learns from any mistakes or corrections, becoming more accurate and efficient.
Natural language processing
Natural language processing or NLP plays a pivotal role in IDP that combines computational linguistics with machine learning and deep learning models to comprehend the intricacies of human language, making it a key component in IDP. Here’s how:
- Text extraction and understanding: NLP aids in extracting and understanding the text from various types of documents. It can recognize and interpret various text formats, including paragraphs, bullet points, tables, and even handwritten notes, making it particularly useful in dealing with unstructured data.
- Contextual understanding: One of the biggest challenges in document processing is understanding the context of information. For instance, the same word could have different meanings in different contexts. NLP algorithms can interpret the context based on surrounding text, helping to identify and extract relevant information accurately.
- Named Entity Recognition (NER): NER is an NLP task that identifies and classifies named entities in text into predefined categories such as names of persons, organizations, locations, expressions of times, quantities, monetary values, percentages, etc. In IDP, NER helps to identify specific data points within the document text, such as the name of a person, a company name, or an invoice number.
- Information Extraction (IE): NLP is also critical in information extraction, where the goal is to convert unstructured text into structured data. This involves tasks like extracting relationships between named entities, identifying the sentiment expressed in the text, or recognizing specific events or facts.
- Text classification and categorization: NLP enables IDP systems to classify and categorize documents based on their content automatically. This is done through text classification techniques, which can sort documents into predefined categories.
- Error detection and correction: NLP also plays a crucial role in error detection and correction in IDP. It can identify anomalies or errors in the extracted data, such as misspelled words or incorrect grammar, and correct them based on the context.
- Continuous learning: One of the significant advantages of NLP is its ability to learn and improve over time. As more documents are processed, the NLP algorithms can learn from any corrections or feedback, becoming more accurate and efficient.
The role of AI and ML in intelligent document processing
Artificial intelligence and machine learning play a pivotal role in intelligent document processing. They enable the automation of processes, extraction of insights from unstructured data, and continuous learning and improvement. Here’s a detailed look at the various ways AI and ML contribute to IDP:
- Automated document classification: AI algorithms can automatically classify documents based on their structure and content. Machine learning models can be trained to recognize different types of documents, such as invoices, contracts, or receipts, and categorize them accordingly. This automation accelerates document processing and reduces the need for manual intervention.
- Data extraction: AI and ML are at the heart of the data extraction process. ML models can be trained to identify and extract specific information from various documents. For instance, an ML model can learn to identify an invoice number or the total amount in an invoice. Similarly, AI technologies like OCR can convert different types of handwritten, typed, or printed text into machine-encoded text.
- Natural language processing: As a subset of AI, NLP plays a crucial role in IDP. NLP enables the system to understand and interpret human language, extracting and analyzing information from unstructured data such as emails, reports, and articles.
- Data validation: AI and ML models can validate the extracted data by comparing it with predefined business rules or other data sources. They can flag potential inaccuracies or inconsistencies for review, ensuring the quality and accuracy of the extracted data.
- Continuous learning and improvement: One of the most significant benefits of AI and ML in IDP is their ability to learn and improve over time. As more documents are processed, the models can learn from any corrections or feedback and adapt their algorithms to improve accuracy and efficiency. This continuous learning capability is crucial for handling the complexity and variability of unstructured data.
- Predictive analysis: Machine learning algorithms can analyze historical data to predict future trends or behaviors. In the context of IDP, this could involve predicting the likelihood of errors in a particular type of document or identifying potential bottlenecks in the document processing workflow.
- Insight generation: AI and ML can generate insights from the extracted data beyond just processing documents. This could involve identifying data patterns, trends, or anomalies, which can inform strategic decision-making.

Step 4: Set up the IDP system
Implementing an IDP solution requires careful configuration and setup to ensure that the system can correctly recognize and process your specific documents and data fields. Here is how this process typically unfolds:
- Understanding document types: First, the IDP system needs to understand the different types of documents it will be dealing with. This could range from invoices and forms to letters and contracts. Each document type has its unique layout, structure, and data fields.
- Defining data fields: For each document type, you will need to define the specific data fields the system should extract. This could be anything from names and addresses on forms to item descriptions and prices on invoices.
- Training the IDP system: Next, the IDP system is trained using a set of sample documents. The system learns to recognize the different document types and the locations of the data fields within them. If the system uses machine learning, this training process will involve feeding it with numerous examples until it can accurately identify and extract the required data.
- Configuring the IDP software: The software then needs to be configured to process the documents according to your specific requirements. This could involve setting up rules for data validation, defining workflows for how the extracted data should be processed, and determining what actions should be taken when exceptions occur.
- Integration with existing systems: The IDP system also needs to be integrated with your existing IT infrastructure. This could involve setting up connections to your databases, ERP systems, or other business applications where the extracted data will be stored or further processed.
- Testing and optimization: Finally, the setup process involves testing the IDP system with real documents to ensure that it can accurately extract and process the required data. Any issues or inaccuracies discovered during this testing phase would need to be addressed, and the system fine-tuned for optimal performance.
Throughout this setup process, your IDP vendor should provide support and guidance. They will likely have a team of experts who can assist with configuring the system, training the AI models, integrating with your existing systems, and troubleshooting any issues that arise.
Step 5: Train the system
Training an intelligent document processing system is a crucial step in its implementation. The goal is to enable the system to accurately identify, extract, and process data from diverse document types. Here is a step-by-step explanation of the process:
- Sample document collection: The first step is gathering a diverse set of sample documents that the system will likely encounter. These documents should represent various types and formats the IDP system needs to handle.
- Data annotation: Once the sample documents are collected, they need to be annotated. This process involves manually marking up the documents to highlight the information that the IDP system needs to extract, such as names, addresses, invoice numbers, etc. This annotated data serves as the “ground truth” that the system will learn from.
- Model training: once the annotated documents are ready, they are fed into the IDP system. The system’s machine learning algorithms use this data to learn patterns and structures of the documents, and how to correctly identify and extract the required data fields. This phase is iterative and may require adjustments to the algorithms or additional training data to improve accuracy.
- Validation and testing: After the initial training, the system needs to be tested to assess its performance. This involves feeding it with new documents (not used in the training phase) and comparing the system’s output with the actual data. This helps in understanding the model’s accuracy and identifying any areas that need improvement.
- Model tuning: Based on the results of the validation and testing phase, the model may need to be fine-tuned. This could involve adjusting the model’s parameters, providing additional training data, or even changing the model structure in more complex cases.
- Active learning: As the system is used in real-world conditions, it continues to learn and improve over time. Any errors that the system makes can be corrected and fed back into the system for further learning. This process, known as active learning, allows the IDP system to continually adapt to changing document formats and improve its performance over time.
Remember, the goal of training an IDP system is to achieve a high level of accuracy in data extraction, minimize manual intervention, and ensure the system can handle a variety of document types and structures.
Step 6: Test and refine
In the implementation of an intelligent document processing system, testing, and refinement is a crucial phase designed to ensure the accuracy of data extraction and the overall performance of the system. It’s an iterative process involving several steps:
- Initial testing: Once the IDP system is set up and trained, it’s tested using real-world documents that haven’t been used during the training phase. This allows for an unbiased evaluation of how well the system performs when confronted with new, unprocessed data.
- Evaluation: The system’s output is compared with the actual data from these documents. Specifically, it is the accuracy of the extracted data that is evaluated. This involves checking whether the system has correctly identified and extracted the necessary data fields. For instance, if the system is designed to extract invoice numbers, dates, and amounts from invoice documents, you would check whether these details have been correctly extracted from the test documents.
- Error identification: Any discrepancies between the actual data and the system’s output are identified. This could involve errors in data extraction, misinterpretation of document structures, or failure to recognize certain data fields. The source of these errors is then investigated.
- Refinement: Based on the results of the evaluation and error identification, adjustments are made to the system. This could involve refining the machine learning algorithms, providing additional training data, or making changes to how the system interprets different document types.
- Iteration: The testing and refinement process is repeated until the system’s performance reaches an acceptable level. This involves running the refined system on new test documents, evaluating its performance, identifying any errors, and making further refinements.
- Continuous improvement: Even after the system is deployed, it’s essential to maintain a feedback loop for continuous improvement. This involves regularly testing the system with new documents, assessing its performance, and making ongoing refinements.
It is worth noting that the testing and refinement phase could require several iterations before the system’s performance is optimized. This is because each adjustment made to the system during the refinement phase could potentially impact how it interprets and processes documents.
Step 7: Integrate with existing systems
Step 8: Roll out and monitor
Once you are confident in the system’s performance, roll it out for full use. Regularly monitor the system’s accuracy and efficiency, and continually retrain it with new data to improve its performance over time.
Implementing an IDP solution is not a one-time task but a continuous process of improvement. As your business evolves, so too will your data processing needs. Stay flexible and keep your IDP system updated to keep pace with your growth.
