Re: [Dbpedia-discussion] how to inference?

Hi Jiusheng,
The example works for me, having loading the data in the firstexample:
$ /usr/local/virtuoso-opensource/bin/isql 1112
Connected to OpenLink Virtuoso
Driver: 05.00.3033 OpenLink Virtuoso ODBC Driver
OpenLink Interactive SQL (Virtuoso), version 0.9849b.
Type HELP; for help and EXIT; to exit.
SQL> sparql define input:inference 'http://localhost:8890/schema/property_rules1' select ?s from <http://localhost:8890/test> where{?s <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://rdfs.org/sioc/ns#Space> };
s
VARCHAR
_______________________________________________________________________________
http://localhost:8890/dataspace/discussion/oWiki-test1Wiki
http://localhost:8890/dataspace/test2/weblog/test2tWeblog
http://localhost:8890/dataspace

3 Rows. -- 4 msec.
Note my test database was an empty database without the DBpediadatasets loaded and default configuration file. Can you try thisusing an empty database and default database yourself (although Ican't see why having dbpedia load should affect things). Also haveyou tried running the DBpedia specific example provided in thatdocumentation section ?

Hugh Williams

Hi Juisheng
The documentation URL (http://docs.openlinksw.com/virtuoso/rdfsparqlrule.html#rdfsparqlruleintro) I sent you yesterdayincludes and example on setting up inferencing for DBpedia as hasbeen done on the live instance we host, have you tried using theexample against your local instance ? There doesn't appear be anyspecific configuration file parameters required for controllinginferencing support.
