Tool/Resource Type Author Description
RITE SDK Framework System CMU This SDK provides a framework which reads the RITE input file, makes decision randomly and outputs the result. It could be used as your implementation base code if you are familiar with Java. We also have a baseline code that compares strings in character base. See sample codes for quickly seeing how you can use the RITE SDK.
JAWJAW Lexical DB CMU Java API for NIST's Japanese WordNet.
WS4J Semantic Similarity calculator CMU Measures semantic similarity between two terms. You can think of the tool as a Java version of WordNet::Similarity that works on NIST's Japanese WordNet.
Wikipedia Redirect Synonym/Alias extractor CMU Extracts pairs of a title and a redirected title (e.g. "USA" -> "United States") from a wikipedia dump on any language
