Query Technologies

In MOLTO we have exploited Grammatical Framework as means for generation of controlled query languages for interactive systems. The latter include information retrieval systems over semantic repositories and a tool for replying mathematical queries in natural language(WP4, WP6, WP7 and WP8). The focus of the presentation is the grammar-ontology interoperability, where we share our experience with generation of SPARQL and verbalizing RDF replies with the help of GF. We summarize the use cases of query technologies in MOLTO and demonstrate the prototype of the patents use case, where GF grammars are used for query language and for means of generation of SPARQL queries.
