Here is one place to lookup Classes or Properties, with results that include Entity Ranking. 1. http://lod.openlinksw.com -- which also has a SPARQL endpoint so you can use bif:contains as part of query pattern 2. http://lod.openlinksw.com/fct/facet.vsp?cmd=load&fsq_id=191140 -- Classes associated with pattern: "Person" 3. http://lod.openlinksw.com/fct/facet.vsp?cmd=load&fsq_id=191141 -- Classes associated with pattern: "Music" 4. http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtuosoFacetsWebService - DBMS hosted Faceted Browser Service APIs .
