Query by Text Annotation

This is a search mechanism that functions similarly to a typical search engine. The domain is the set of maize mutant image captions from MaizeGDB. The uniqueness of this engine is that queries are enriched by using plant ontologies like PO and GO. This is done by (1) mapping query terms to terms in the ontologies and (2) including additional terms to the query utilizing ontologic relationships (synonyms, parents, children, etc). The best-matching captions are retrieved and displayed with their corresponding images.
