What is LSA?
Latent Semantic Analysis (LSA) is a natural language processing technique that uses statistical methods to identify associations between words in a document.
Key aspects of LSA include:
-
It addresses issues of semantic similarity, such as recognizing that "mobile," "phone," "cell phone," and "telephone" are related concepts.
-
LSA assumes that words used in the same context are analogous and that ambiguity in word choice can obscure hidden semantic structures.
