Introduction:

Opinion mining and topic modeling are two important techniques in the field of natural language processing and machine learning. Opinion mining, also known as sentiment analysis, involves the extraction and analysis of opinions or sentiments expressed in textual data, such as reviews, comments, and social media posts. Topic modeling, on the other hand, is a technique used to discover latent topics present in a collection of documents.

In this thesis, we will explore the use of opinion mining and topic modeling techniques to analyze large volumes of textual data. We will investigate how these techniques can be applied to various domains, such as customer reviews, social media posts, and news articles, to extract valuable insights and patterns.

Thesis Overview:

Opinion mining and topic modeling are two powerful techniques that can be used to extract valuable insights from large volumes of textual data. Opinion mining, also known as sentiment analysis, involves the extraction and analysis of opinions or sentiments expressed in textual data, such as reviews, comments, and social media posts. Topic modeling, on the other hand, is a technique used to discover latent topics present in a collection of documents.

In this thesis, we will explore the application of opinion mining and topic modeling techniques in various domains, such as customer reviews, social media posts, and news articles. We will discuss the methodologies used for data collection and preprocessing, as well as the evaluation metrics used to assess the performance of the models.

Through the analysis of our findings, we aim to provide insights into how opinion mining and topic modeling can be used to extract valuable information from textual data. We will also discuss the contributions of our study and suggest future research directions in this field.
