latent semantic analysis (lsa) is a statistical technique used to uncover relationships between words and documents. it can be used to determine the most relevant words for a document, to find similar documents, and for document summarization.

topic modelling is a technique used to find and extract the main topics from a collection of documents. it can be used to find relationships between documents and discover clusters of documents about similar topics.
