Examples of PseudoWordContextExtractor

edu.ucla.sspace.wordsi.psd.PseudoWordContextExtractor

A pseudo word based {@link ContextExtractor}. A mapping from real tokens to pseudo words is used to automatically replace tokens in a corpus while {@link Wordsi} processes contexts. Only pseudo words are represented in the {@link Wordsi} space. When a token is encountered, if it has a pseudo word mapping,that instance is replaced with the pseudo word mapping. A context vector will be generated for the context surrounded that word instance, and the pseudo word replacement will serve as the primary key for the reporter and the raw token will serve as the secondary key. The pseudo word will then replace the raw token in the context for all other words, and thus serve as a feature in place of the real token. @author Keith Stevens
