Paraphrasing: Boosting Queries
Idilia has developed technology that, given a set of word senses, can paraphrase that set of word senses into an equivalent set of word senses that collectively mean the same thing, but use different words and/or syntax. This technology is applicable to queries, among other possible applications. Once the meanings of the words in a query have been automatically selected by WSD, Idilia’s paraphrasing technology can identify equivalent collections of meanings using a set of algorithms combined with Idilia’s massive Language Graph. Thus, for example, “text to speech software" can be paraphrased into “speech synthesis application”. It is important to note that paraphrasing is not possible without WSD. In this example, the word “charter” cannot be paraphrased without first selecting its correct meaning. Attempting to paraphrase all possible meanings of a term leads to massive over-generation of paraphrases, the vast majority of which are wrong.
