Snowball compiler and stemming algorithms
Snowball is a small string processing language for creating stemming algorithms for use in Information Retrieval, plus a collection of stemming algorithms implemented using it.
Snowball was originally designed and built by Martin Porter. Martin retired from development in 2014 and Snowball is now maintained as a community project. Martin originally chose the name Snowball as a tribute to SNOBOL, the excellent string handling language from the 1960s. It now also serves as a metaphor for how the project grows by gathering contributions over time.
The Snowball compiler translates a Snowball program into source code in another language – currently ISO C, C#, Go, Java, Javascript, Object Pascal, Python and Rust are supported.
This repository contains the source code for the snowball compiler and the stemming algorithms. The snowball
