If you look at the original Wordnet search and select "Display options: Show Lexical File Info", you'll see an extremely useful classification of words called lexical file. Eg for "filling" we have:
<noun.substance>S: (n) filling, fill (any material that fills a space or container)
<noun.process>S: (n) filling (flow into something (as a container))
<noun.food>S: (n) filling (a food mixture used to fill pastry or sandwiches etc.)
<noun.artifact>S: (n) woof, weft, filling, pick (the yarn woven across the warp yarn in weaving)
<noun.artifact>S: (n) filling ((dentistry) a dental appliance consisting of ...)
<noun.act>S: (n) filling (the act of filling something)
The first thing in brackets is the "lexical file". Unfortunately I have not been able to find a SPARQL endpoint that provides this info
The latest RDF translation of Wordnet 3.0 points to two things:
Talis SPARQL endpoint. Use eg this query to check there's no such info:
DESCRIBE <http://purl.org/vocabularies/princeton/wn30/synset-chair-noun-1>
W3C's mapping description. Appendix D "Conversion details" describes something useful: wn:classifiedByTopic.
But it's not the same as lexical file, and is quite incomplete. Eg "chair" has nothing, while one of the senses of "completion" is in the topic "American Football"
DESCRIBE <http://purl.org/vocabularies/princeton/wn30/synset-completion-noun-1> ->
<j.1:classifiedByTopic rdf:resource="http://purl.org/vocabularies/princeton/wn30/synset-American_football-noun-1"/>
The question: is there a public Wordnet query API, or a database, that provides the lexical file information?
It can be done through MIT JWI (MIT Java Wordnet Interface) a Java API to query Wordnet. There's a topic in this link showing how to implement a java class to access lexicographic
