Topic Modelling

Topic modeling is a statistical method for discovering the abstract “topics” that occur in a collection of documents. It is a type of unsupervised learning, meaning that it does not require any labeled data to train a model. Instead, it uses statistical techniques to find patterns in the data and group similar documents together. This makes topic modeling an excellent tool for exploring large collections of text data, such as news articles, scientific papers, or social media posts. It can be used to identify the main themes and trends in a dataset, as well as to track how these themes change over time. Researchers, analysts, and marketers use topic modeling for a wide range of applications such as:

• Discovering trends: Topic modeling can be used to identify emerging trends in a dataset. For example, a researcher might use topic modeling to analyze a collection of news articles to identify the key topics that are being discussed.
• Categorizing documents: Topic modeling can be used to categorize documents into different topics. This can be useful for organizing a large collection of documents or for creating a taxonomy of topics.
• Summarizing documents: Topic modeling can be used to summarize documents by identifying the key topics that they contain. This can be useful for creating abstracts or summaries of large documents.
• Generating keywords: Topic modeling can be used to generate keywords for a document or collection of documents. This can be useful for indexing documents or for creating a search engine.
• Personalizing content: Topic modeling can be used to personalize content for users. For example, a news website might use topic modeling to recommend articles to users based on their interests.
