Text Retrieval Using Linear Algebra

December 15, 2002

Who knew 24 years ago that this peek into modeling a collection of web pages as a term-by-document matrix and ranking relevance via cosine similarity between a query vector and each document vector would presage the modern AI explosion? Not me. Here's the paper I wrote, "Text Retrieval Using Linear Algebra," including C++ and Perl source code, along with now-well-trodden paths for future investigation.
