Description

Dive into the world of computational linguistics with FreeCache, a classic and efficient part-of-speech (POS) tagger written in Perl. This CGI script utilizes sophisticated Markov models to analyze text and assign grammatical tags (like noun, verb, adjective) to each word. Originally designed for corpus annotation and statistical analysis, FreeCache is a fascinating example of early algorithmic text processing. It's a lightweight, powerful tool for developers and data scientists interested in natural language processing (NLP) or the history of web-based algorithms.
