Topic Modelling

Topic modeling is a technique for uncovering the hidden topics or themes in a collection of documents. It is commonly used in natural language processing and information retrieval to automatically organize and summarize large collections of text data. Topic modeling algorithms use techniques from machine learning and statistics to identify the underlying topics in a corpus of documents and assign each document to one or more of these topics.

Topic modeling is a useful tool for exploring and understanding large collections of text data. It can help to identify the main topics or themes in a corpus of documents, and it can also be used to group similar documents together or to visualize the relationships between different topics. Additionally, topic modeling can be used as a preprocessing step for other natural language processing tasks, such as document classification or sentiment analysis.
