Wordnet Representations - RDF/XSD/OWL

Hi Everyone,

 

As part of a taxonomy framework, we will be linking taxonomies lexically by
requiring each term to be mapped to a WordNet synonym or synset.

As a start, I created an XSD schema and instance that follows the striped
syntax and is thus also parseable as RDF.

Here is a partial sample instance:

<wn:Word xmlns:rdf='http://www.w3.org/1999/02/22-rdf-syntax-ns#'
xmlns:wn='http://www.daconta.net/wn#' rdf:ID='dog'
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.daconta.net/wn# Word.xsd" >

            <wn:partsOfSpeech rdf:parseType='Collection'>

               <wn:PartOfSpeech wn:type='verb'>

                  <wn:concepts rdf:parseType='Collection'>

                        <wn:Concept rdf:ID='_1943890'>

                           <wn:definition>go after with the intent to catch;
&quot;The policeman chased the mugger down the alley&quot;; &quot;the dog
chased the rabbit&quot;</wn:definition>

                             <wn:relations  rdf:parseType='Collection'>

                                    <wn:Relation wn:type='hypernym'
wn:tgt='_1942900'/>                              ...

                                    <wn:Relation wn:type='hyponym'
wn:tgt='_1946245'/>

                             </wn:relations>

                              <wn:synonyms rdf:parseType='Collection'>

                                    <wn:Synonym wn:lemma='chase_after'/>

                                    <wn:Synonym wn:lemma='give_chase'/>

                         </wn:synonyms>

                          </wn:Concept>

             </wn:concepts>

            </wn:PartOfSpeech> .

 

 

If you are interested in playing around with this, there is a schema, test
program and simple web service at 

http://www.daconta.net/project_folder/WordnetMetamodel.html .

 

I have two questions for this group . 

1. Would it be better to leave this as RDF or create an OWL ontology for the
Wordnet metamodel.

2. How would you handle wordnet addressing?  In other words, a link from a
Topic to a Wordnet Concept (aka synset) or 

Synonym.  Another aspect of this would be how closely wordnet relations, map
to XTM associations and OWL relations.

 

Thanks for any feedback,
