I decided to help out at Apertium because I find the work here quite interesting and I believe Apertium will benefit many.
The following are projects related to Apertium.
 is a crawler for Wiktionary which aims to extract data from pages. It was created for a GCI task which you can read about at Task ideas for Google Code-in/Scrape inflection information from Wiktionary.
The crawler crawls a starting category (usually Category:XXX language)for subcategories, then crawls these subcategories for pages. It then passes the page to language-specific parsers which turn it into the Speling format.
The current languages supported are Chinese (zh), Thai (th) and Lao (lo). You are welcome to contribute to this project.
Spaceless Segmentation has been merged into Apertium under . It serves to tokenize languages without any whitespace. More information can be found under Task ideas for Google Code-in/Tokenisation for spaceless orthographies.
A write-up on this tokeniser will be available quite soon.
