title: How to find the "lexical file" in Wordnet?
body: <p>If you look at the <a href="http://wordnetweb.princeton.edu/perl/webwn?s=filling&amp;sub=Search%20WordNet&amp;o2=&amp;o0=&amp;o8=1&amp;o1=1&amp;o7=&amp;o5=&amp;o9=&amp;o6=&amp;o3=&amp;o4=1&amp;h=100" rel="noreferrer">original Wordnet search</a> and select "Display options: Show Lexical File Info", you'll see an extremely useful classification of words called <strong>lexical file</strong>. Eg for "filling" we have:</p>
  
  <pre><code>   &lt;noun.substance&gt;S: (n) filling, fill (any material that fills a space or container)
     &lt;noun.process&gt;S: (n) filling (flow into something (as a container))
     &lt;noun.food&gt;S: (n) filling (a food mixture used to fill pastry or sandwiches etc.)
     &lt;noun.artifact&gt;S: (n) woof, weft, filling, pick (the yarn woven across the warp yarn in weaving)
     &lt;noun.artifact&gt;S: (n) filling ((dentistry) a dental appliance consisting of ...)
     &lt;noun.act&gt;S: (n) filling (the act of filling something) 
  </code></pre>
  
  <p>The first thing in brackets is the "lexical file". Unfortunately I have not been able to find a SPARQL endpoint that provides this info</p>
  
  <ul>
  <li><p>The <a href="http://semanticweb.cs.vu.nl/lod/wn30/%20includes" rel="noreferrer">latest RDF translation</a> of Wordnet 3.0 points to two things:</p></li>
  <li><p><a href="http://api.talis.com/stores/wordnet/services/sparql" rel="noreferrer">Talis SPARQL endpoint</a>. Use eg this query to check there's no such info:</p>
  
  <p><code>DESCRIBE &lt;http://purl.org/vocabularies/princeton/wn30/synset-chair-noun-1&gt;</code></p></li>
  <li><p><a href="http://www.w3.org/TR/wordnet-rdf/" rel="noreferrer">W3C's mapping description</a>.  Appendix D "Conversion details" describes something useful: <code>wn:classifiedByTopic</code>. 
  But it's not the same as <strong>lexical file</strong>, and is quite incomplete. Eg "chair" has nothing, while one of the senses of "completion" is in the topic "American Football"</p>
  
  <p><code>DESCRIBE &lt;http://purl.org/vocabularies/princeton/wn30/synset-completion-noun-1&gt;</code> -> </p>
  
  <p><code>&lt;j.1:classifiedByTopic rdf:resource="http://purl.org/vocabularies/princeton/wn30/synset-American_football-noun-1"/&gt;</code></p></li>
  </ul>
  
  <p>The question: is there a public Wordnet query API, or a database, that provides the <strong>lexical file</strong> information?</p>
