lsemantica: A command for text similarity based on latent semantic analysis
Carlo Rasmus Schwarz · The Stata Journal Promoting communications on statistics and Stata · 2019
In this article, I present the lsemantica command, which implements latent semantic analysis in Stata. Latent semantic analysis is a machine learning algorithm for word and text similarity comparison and uses truncated singular value decomposition to derive the hidden semantic relationships between words and texts. lsemantica provides a simple command for latent semantic analysis as well as complementary commands for text similarity comparison.
