This article explores AI for sentiment analysis, its value to your business, and the process of implementing it to help you unlock its full potential. Read on as we delve deeper into the captivating world of AI in sentiment analysis.

What is sentiment analysis?

Sentiment analysis, also referred to as opinion mining, is a method to identify and assess sentiments expressed within a text. The primary purpose is to gauge whether the attitude towards a specific topic, product, or service is positive, negative, or neutral. This process utilizes AI and natural language processing (NLP) to interpret human language and its intricacies, allowing machines to understand and respond to our emotions.

Consider this process akin to mining a wealth of data, identifying hidden nuggets of sentiments in them that can provide actionable business insights. Rather than merely scratching the surface with rudimentary sentiment analysis, businesses can delve deeper using advanced AI techniques.

To illustrate, let’s consider three examples:

  1. Suppose a customer writes an online review saying, “I love the friendly staff and quick service at this restaurant.” Sentiment analysis would categorize this feedback as positive due to the presence of words like ‘love,’ ‘friendly,’ and ‘quick’ in the feedback.
  2. On the other hand, a comment such as “The laptop is good, but it overheats too quickly” contains mixed sentiments. While the customer appreciates some aspect of the product (‘good’), the negative sentiment is expressed in ‘overheats too quickly.’
  3. A neutral sentiment could be something like “The book was received on time,” which neither praises nor criticizes the product or service.

Through sentiment analysis, businesses can go beyond simple count-based metrics, capturing high-value insights from customer conversations and social media streams. As a result, they can comprehensively understand customer sentiments, improve customer experiences, and ultimately enhance their product or service offerings.

Types of sentiment analysis

Sentiment analysis encompasses a variety of analytical methods that help understand the sentiment or emotional tone behind textual data. Here are four key types:

  1. Aspect-based sentiment analysis: This approach allows us to understand the sentiment related to specific product or service aspects. Instead of merely determining whether the sentiment is positive or negative, it drills down to discover the sentiment about individual features or aspects. For example, in the case of a restaurant, aspects might include “food quality,” “ambiance,” or “service speed.”
  2. Fine-grained sentiment analysis: This technique refines sentiment polarity by distinguishing degrees of sentiment. Instead of merely classifying sentiments as positive, negative, or neutral, it breaks them down into more specific categories such as “very positive,” “somewhat positive,” “neutral,” “somewhat negative,” or “very negative.” This is particularly useful for detailed analysis of reviews or ratings, offering a granular view of customers’ sentiments.
  3. Emotion detection: This form of sentiment analysis identifies specific emotions within textual data. Instead of determining whether the sentiment is positive, neutral, or negative, it categorizes the emotions expressed in the text, like joy, surprise, anger, sadness, fear, etc. This offers a deeper understanding of the user’s emotional state.
  4. Intent analysis: This type aims to understand the intention or goal behind a particular text. By identifying the underlying intent, organizations can gain insights into customer behavior, predict future actions, and adapt their strategies accordingly. It’s especially useful in scenarios like customer service, where predicting a customer’s behavior can help plan effective responses.

    How does AI-based sentiment analysis work?

    Sentiment analysis, a subset of AI, employs the techniques of natural language processing and machine learning to automatically categorize a given text as positive, negative, or neutral based on the embedded emotions and opinions.

    The NLP element converts human language into a form that machines can interpret. This is achieved through syntactic and semantic techniques. Syntactic techniques focus on understanding the structure of a text using methods such as tokenization, lemmatization, and part-of-speech tagging, while semantic techniques aim to comprehend the text’s meaning.

    After the text is processed using NLP techniques, it’s then prepared for categorization using machine learning algorithms. Machine learning algorithms enable machines to identify patterns within data and subsequently predict outcomes. Instead of depending on explicit programming, these algorithms learn from a variety of similar examples known as training data.

    To construct a model that classifies text based on sentiment, you need to train it with examples of emotional expressions in the text. Each of these instances needs to be marked with an appropriate category. Many samples for each category are required to enhance your model’s accuracy. After being exposed to numerous examples, the model begins to link specific inputs (text) with particular categories. These learned criteria are then used to predict new, unseen content tags.

    One noteworthy aspect of sentiment analysis with AI is its ability to tag large data sets simultaneously and in real-time. As the machine learning algorithms grow more sophisticated with experience, sentiment analysis models will improve their proficiency over time as they categorize new data.

    Traditionally, companies used surveys and focus groups to understand customers’ sentiments toward their products. However, the advent of big data analytics has allowed organizations to delve into larger data volumes, like social media data, to gain a more accurate depiction of customer opinions.

    AI for sentiment analysis

    AI-based sentiment analysis predominantly employs two techniques:

    1. Rule-based sentiment analysis: This method uses a set of predefined rules along with a sentiment-labeled dictionary. The system uses NLP techniques to identify words before comparing them against the dictionary. The sentiment score derived at the end considers other factors, such as negations and dependencies. However, this method has limitations, such as its inability to understand sarcasm or the context of words in a sentence, and it requires regular updates and maintenance.
    2. Machine learning-based sentiment analysis: Trains a machine learning model on labeled datasets. After enough training, the algorithm can discern sentiments from new texts without depending on predefined rules, enabling it to detect complexities like sarcasm and synonyms.

    According to some sources, there’s also a hybrid approach that merges the rule-based and machine-learning methods, often producing more accurate results.

    Other key AI technologies that are employed in sentiment analysis are as follows. And here is how they work:

    • Machine Learning with manual feature selection: NLP shifted from manually coded rules to machine learning models in the early years. These early models often combined hand-selected features and weights. An engineer could create a series of features – for instance, whether the word “not” appears within a five-word window – and the machine learning model (like logistic regression) would then determine that feature’s significance in determining the text’s sentiment.
    • Deep learning and word embeddings: The advent of word vector embedding models like Word2Vec and GloVe in 2013, primarily developed by Google researcher Tomáš Mikolov and his team, transformed sentiment analysis. Word embeddings assign a unique vector to every word in a given lexicon. Words with similar meanings or functions are situated close to each other in this vector space, while dissimilar words are located farther apart. These embeddings transform a sentence from plain text into a numerical matrix analogous to an image. This matrix can then be input into a deep neural network, such as a Convolutional Neural Network (CNN), Recurrent Neural Network (RNN), or Long Short-term Memory (LSTM) network. Combining word embeddings with neural networks enables the model to discern context within a sentence, enhancing the robustness of sentiment analysis algorithms to linguistic nuances and variations.
    • Transformers: The transformer-based models represent the current state of the art in sentiment analysis. The most notable transformer model is BERT (Bidirectional Encoder Representations from Transformers). Similar to word vector embeddings, transformer models transform words in a sentence into vectors within a high-dimensional space. However, a key advantage of transformers is their ability to represent a word with different vectors based on its context within the sentence, enabling a more nuanced understanding of sentence sentiment.

How to do sentiment analysis using LSTM?

We will show how to do sentiment analysis on movie reviews using LSTMs. LSTM networks are enhanced versions of RNNs specifically designed to learn sequential data and its long-range dependencies more effectively than traditional RNNs. They find wide applications in areas of deep learning, such as predicting stock trends, recognizing speech, and processing natural language.

We will be using the IMDB movie review dataset that can be downloaded from this link –

Follow the undermentioned steps.

Import and display the data

Download the data from the given link and load it using the below code to view the data:

# read data from text files
with open('aclImdb/test/neg/10000_4.txt', 'r') as f:
 reviews =
with open('aclImdb/test/neg/10000_4.txt', 'r') as f:
 labels =
Output - This is an example of why the majority of action f
This is an example of why

Now convert the data into lowercase and remove the punctuation

reviews = reviews.lower()
from string import punctuation
all_text = ''.join([c for c in reviews if c not in punctuation])

Data processing: Generate a list of reviews

We have consolidated all the text into one large string. Now, our next step is to split this into individual reviews and store them as separate elements in a list, such as [review_1, review_2, review_3… review_n].

reviews_split = all_text.split('\n')
print ('Number of reviews :', len(reviews_split))
Output - Number of reviews : 1

Tokenization: Establish a dictionary mapping vocabulary to integers

For many Natural Language Processing (NLP) tasks, it’s common to construct a dictionary that maps indexes in a way that words appearing more frequently are assigned lower indexes. A popular approach for accomplishing this involves the use of the Counter method from the Collections library.

from collections import Counter
all_text2 = ' '.join(reviews_split)
# create a list of words
words = all_text2.split()
# Count all the words using Counter Method
count_words = Counter(words)
total_words = len(words)
sorted_words = count_words.most_common(total_words)

To establish a dictionary mapping vocabulary to integers, you would proceed as follows:

vocab_to_int = {w:i for i, (w,c) in enumerate(sorted_words)}

Here’s a minor detail to consider: In this mapping, indexing begins from 0, meaning ‘the’ would be mapped to 0. However, we will later need to add padding to shorter reviews, and the standard choice for padding is 0. Therefore, it’s necessary to start this indexing from 1.

vocab_to_int = {w:i+1 for i, (w,c) in enumerate(sorted_words)}

Tokenization: Convert words into an encoded form

Up until now, we have crafted a) a list of reviews and b) a dictionary mapping indexes using the vocabulary derived from all our reviews. The objective of these steps was to encode the reviews, replacing the words in our reviews with corresponding integers.

reviews_int = []
for review in reviews_split:

Tokenization: Convert labels into encoded form

This step is straightforward as we have only two output labels. Accordingly, we will designate ‘positive’ with the number 1 and ‘negative’ with the number 0.

import numpy as np
labels_split = ['positive', 'negative', 'positive', 'positive', 'negative']
encoded_labels = [1 if label =='positive' else 0 for label in labels_split]
encoded_labels = np.array(encoded_labels)

Examine the lengths of reviews

import pandas as pd
import matplotlib.pyplot as plt
%matplotlib inline
reviews_len = [len(x) for x in reviews_int]
count      1.0
mean     232.0
std        NaN
min      232.0
25%      232.0
50%      232.0
75%      232.0
max      232.0
dtype: float64

The generated plot looks like the following:

Eliminating outliers: Disposing of excessively long or short reviews

reviews_int = [ reviews_int[i] for i, l in enumerate(reviews_len) if l>0 ]

Padding or truncating the remaining data

To manage both short and long reviews, we will adjust all our reviews to a specified length, which we will refer to as the Sequence Length. This length corresponds to the number of time steps for the LSTM layer.

For reviews shorter than the sequence length, we will add padding with 0s. Conversely, for reviews longer than the sequence length, we will truncate them to include only the first set of words up to the sequence length.

def pad_features(reviews_int, seq_length):
    ''' Return features of review_ints, where each review is padded with 0's or truncated to the input seq_length.
    features = np.zeros((len(reviews_int), seq_length), dtype = int)
    for i, review in enumerate(reviews_int):
        review_len = len(review)
        if review_len <= seq_length:             zeroes = list(np.zeros(seq_length-review_len))             new = zeroes+review         elif review_len > seq_length:
            new = review[0:seq_length]
        features[i,:] = np.array(new)
    return features

Splitting the dataset into training, validation, and test sets

After preprocessing our data into an appropriate format, we will divide it into training, validation, and test sets.

The distribution will be as follows: 80% for training, 10% for validation, and 10% for testing.

# Assuming you have defined the reviews_int variable with your data
# and you want to set the sequence length to 100
seq_length = 100
# Call the pad_features function with reviews_int and seq_length
features = pad_features(reviews_int, seq_length)
# The rest of the code remains the same
split_frac = 0.8
train_x = features[0:int(split_frac*len(reviews_int))]
train_y = encoded_labels[0:int(split_frac*len(reviews_int))]
remaining_x = features[int(split_frac*len(reviews_int)):]
remaining_y = encoded_labels[int(split_frac*len(reviews_int)):]
valid_x = remaining_x[0:int(len(remaining_x)*0.5)]
valid_y = remaining_y[0:int(len(remaining_y)*0.5)]
test_x = remaining_x[int(len(remaining_x)*0.5):]
test_y = remaining_y[int(len(remaining_y)*0.5):]

Loading data and organizing it into batches

Once we have separated our data into training, testing, and validation sets, the following step is to construct dataloaders for this data. Rather than using a generator function to batch our data, we will opt to use a TensorDataset.

import numpy as np
import torch
from import DataLoader, TensorDataset
# Assuming you have some data in numpy arrays
train_x = np.random.rand(100, 10)  # 100 samples, 10 features
train_y = np.random.randint(0, 2, size=(100,))  # 100 labels (binary)
# Create Tensor datasets
train_data = TensorDataset(torch.from_numpy(train_x), torch.from_numpy(train_y))
# DataLoader
batch_size = 50
train_loader = DataLoader(train_data, shuffle=True, batch_size=batch_size)

To procure a single batch of training data for visualization purposes, we will establish a data iterator.

# obtain one batch of training data
dataiter = iter(train_loader)
sample_x, sample_y = next(dataiter) # Use `next()` directly on the iter object
print('Sample input size: ', sample_x.size()) # batch_size, seq_length
print('Sample input: \n', sample_x)
print('Sample label size: ', sample_y.size()) # batch_size
print('Sample label: \n', sample_y)
Sample input size:  torch.Size([50, 10])

On user-generated data

Initially, we will define a function called ‘tokenize’ that handles the pre-processing tasks. Subsequently, we will create a ‘predict’ function that delivers the final output after analyzing the user-supplied review.

import numpy as np
import torch
from string import punctuation
# Define the SentimentLSTM class and other necessary variables here
# Define the negative review text you want to test
test_review_neg = "This movie was really disappointing. The acting was bad and the plot made no sense."
# Tokenization and preprocessing
def tokenize_review(test_review):
    test_review = test_review.lower()
    test_text = ''.join([c for c in test_review if c not in punctuation])
    test_words = test_text.split()
    test_ints = [vocab_to_int[word] for word in test_words if word in vocab_to_int]
    return test_ints
# Define the sequence length
seq_length = 200
# Tokenize and preprocess the review
test_ints = tokenize_review(test_review_neg)
# Padding
features = pad_features([test_ints], seq_length)
# Convert to tensor
feature_tensor = torch.from_numpy(features)
# Model prediction
def predict(net, test_feature_tensor):
    batch_size = test_feature_tensor.size(0)
    h = net.init_hidden(batch_size)
    if train_on_gpu:
        test_feature_tensor = test_feature_tensor.cuda()
    output, h = net(test_feature_tensor, h)
    pred = torch.round(output.squeeze())
    return pred.item()
# Predict the sentiment
prediction = predict(net, feature_tensor)
# Print the prediction
if prediction == 1:
    print("Positive review detected!")
    print("Negative review detected.")

Generated output

Negative review detected.
