Re: [ontolog-forum] natural language end-point to knowledge base (aka on

[Enrico Motta <e.motta@xxxxxxxxxx>]

you may want to have a look at PowerAqua, http://technologies.kmi.open.ac.uk/poweraqua/. It provides a natural language front end to a 'Semantic Web', which means it can be used with back end repositorites which can be heterogeneous in nature, such as the set of ontologies and RDF resources crawled by Watson, http://watson.kmi.open.ac.uk/. In other words, PowerAqua does not require any kb-specific customization to work, it uses WordNet and the SW itself as sources of background knowledge, to try and map NL queries to statements in a (possibly heterogeneous) back end repository.

The demo page, http://technologies.kmi.open.ac.uk/poweraqua/demo.html, contains two instances of the system, which you can try out.

Good Luck!

Enrico

PS Please note that, depending on the query, you may have to wait a while for an answer!
