The Cylleneus project is developing a next-generation corpus search engine, making use of the rich lexical and semantic data of the WordNet. This means that, besides basic word-form and lemma-based searches, users can use Cylleneus to query Latin (and eventually Greek) texts based on both their semantic and their syntactic properties. In other words, for the first time, texts can be searched on the basis of the meanings of words as well as of the kinds of grammatical constructions they appear in. Queries can also take advantage of the semantic and domain relations encoded in the WordNet, allowing users to search for broad conceptual fields like "Anatomy" or "Agriculture" and to search for classes of words defined by synonymy, antonymy, hypernymy, hyponymy, and so on.
Cylleneus is in development but is currently usable as a command line application.
