Popular Dataset Examples used for Sentiment Analysis

Types of Approach for Sentiment Analysis

We can broadly classify customer sentiment analysis into two categories:
1. Lexicon-Based Approach
2. Machine Learning Approach

Lexicon-Based Approach:
The lexicon-based approach uses sentiment lexicons or dictionaries containing words and their associated sentiment scores. The sentiment of a text is calculated by matching the words in the text with the lexicon entries.

Lexicon Approach can be further classified into:
  A. Corpus-Based Approach
  B. Dictionary-Based Approach

  A. Corpus-Based Approach:
The corpus-based approach involves training a sentiment classifier using a labeled dataset of text. The classifier learns from the patterns and sentiments in the labeled data and can predict the sentiment of new, unseen text.

Example: Using a dataset of customer reviews labeled as positive, negative, or neutral, a corpus-based sentiment classifier can determine the sentiment of a new review based on the patterns learned from the labeled reviews.


Example: By analyzing the frequency of positive and negative words in a text, a statistical approach can predict the sentiment. If a sentence has more positive words than negative words, it is classified as having a positive sentiment.

  B. Dictionary-Based Approach:
The dictionary-based approach is similar to the lexicon-based approach but considers additional factors like word variations and context to determine sentiment. It may also account for sentiment-modifying words like negations.

Example: "I am not happy with the service." - The dictionary-based approach recognizes the negation "not" and modifies the sentiment of "happy" to negative.

  2. Machine Learning Approach:
The machine learning approach involves training models, such as neural networks or decision trees, on labeled datasets. These models learn from the data and can predict the sentiment of new text based on the learned patterns.

Using a machine learning approach, a model can be trained on a dataset of customer reviews labeled as positive or negative. The trained model can then classify new reviews as positive or negative based on the patterns it learned during training.

Machine learning approach can be further classified into:
  A. Semi-supervised Learning
  B. Supervised Learning
  C. Unsupervised Learning

  A. Semi-supervised Learning:
Semi-supervised learning combines both labeled and unlabeled data. Initially, a sentiment classifier is trained using a small labeled dataset. Then, the model is applied to the unlabeled data, and the confident predictions are used to further train the model.

Example: A sentiment classifier is initially trained on a small set of labeled customer reviews. The model is then used to predict the sentiment of a larger set of unlabeled reviews, and the confident predictions are added to the labeled dataset for retraining.

  B. Supervised Learning:
In supervised learning, a sentiment classifier is trained using a labeled dataset, where each text sample is annotated with its sentiment. The model learns from the labeled examples and can predict the sentiment of new, unseen text.

Example: A sentiment classifier is trained using a dataset of customer reviews labeled as positive or negative. The model learns the patterns and relationships between the textual features and the sentiment labels. For example, the classifier learns that phrases like "excellent service" indicate positive sentiment, while phrases like "poor quality" indicate negative sentiment. Once trained, the supervised learning model can accurately predict the sentiment of new, unseen customer reviews based on these learned patterns.

  C. Unsupervised Learning:
Unsupervised learning approaches for sentiment analysis aim to discover sentiment patterns and structures in unlabeled data without relying on predefined sentiment labels. These methods use algorithms to identify natural groupings or topics within the data, which can then be associated with sentiment.

Example: Let's say we have a large dataset of social media posts discussing a new smartphone. Using unsupervised learning techniques like clustering, the algorithm can automatically group similar posts together based on their content. It might form clusters of posts expressing positive sentiment, negative sentiment, or neutral sentiment. This helps in understanding the sentiment distribution within the dataset without the need for manually labeling each post.

Leveraging your Conversational Data for Sentiment Analysis

Conversational data has become a valuable resource for businesses seeking to understand customer sentiments and preferences. By analyzing customer support chats, social media interactions, online reviews, emails, and surveys, businesses can gain valuable insights into their customers' thoughts and emotions.
