Hi I'm implementing an equivalent of dbPedia lookup service  in semantic_forms, leveraging on Lucene integration in TDB, and dbPedia mirror with TDB  .
The dbPedia lookup service is really nice but: - the hosted service is often down - completion is in english only A lookup service with TDB and Lucene would overcome these 2 problems. So I would need completion with Lucene from SPARQL. According to Jena doc., this does not seems to be implemented: https://jena.apache.org/documentation/query/text-query.html#query-with-sparql There are plenty of pages when searching for lucene completion >From these pages there is a code snippet here http://stackoverflow.com/questions/120180/how-to-do-query-auto-completion-suggestions-in-lucene but a regular Lucene API may exist.  https://github.com/dbpedia/lookup  https://github.com/jmvanel/semantic_forms/blob/master/doc/en/administration.md#populating-with-dbpedia-mirroring-dbpedia -- Jean-Marc Vanel Profil: http://18.104.22.168:9111/display?displayuri=http%3A%2F%2Fjmvanel.free.fr%2Fjmv.rdf%23me Déductions SARL - Consulting, services, training, Rule-based programming, Semantic Web +33 (0)6 89 16 29 52 Twitter: @jmvanel , @jmvanel_fr ; chat: irc://irc.freenode.net#eulergui
