Role in this project:Back-end Developer
Back-end DeveloperContributions:135 commits in 11 years 10 months
Contributions summary:Richard primarily contributed to the Snowball stemming algorithms and compiler. Their work included refactoring the build system, moving algorithms into subdirectories, and integrating new stemming algorithms like "lovins" and "german2". They also added features like the ability to get the length of a stemmed word and a listing of available stemmers, and updated the example to include language selection. They also worked on adding character encoding support and implemented C++ compatibility, and also refactored the Java interface.
