<div>Dear Liling,</div>
<div> </div>
<div>The book on Wordnet is:</div>
<div> </div>
<div>WordNet: An Electronic Lexical Database</div>
<div>edited by</div>
<div>Christiane Fellbaum</div>
<div>MIT Press, 1998</div>
<div> </div>
<div>Thus, Wordnet is an electronic lexical database.</div>
<div> </div>
<div>Nicola Guarino in his lecture at the First OntoLex Workshop 2000</div>
<div>defines precision of ontologies like:</div>
<div> </div>
<div>- Lexicon (example, Machine Readable Dictionaries) - Vocabulary with NL
definitions</div>
<div>- Simple Taxonomy (example, Clasifications)</div>
<div>- Thesaurus (example, WordNet) Lexical relations</div>
<div>- Taxonomy plus related-terms (example, Relational Model) Light-weight
ontologies - Unconstrained use of arbitrary relations</div>
<div>- Fully Axiomatized Theory (Heavy-weight ontologies)</div>
<div> </div>
<div>Thus, WordNet is a kind of ontology.</div>
<div> </div>
<div>With best regards,</div>
<div> </div>
<div>Kiril</div>

<div dir="ltr">Dear corpora linguists,
<div> </div>
<div>There is recently a discussion on stackoverflow about "wordnet vs
ontology". I would like your perspective on several issues about wordnet and
ontology:</div>
<div> </div>
<div>- Is wordnet an ontology? If it is not an ontology, what is it?</div>
<div> </div>
<div>- What is the definition of an ontology? Is anything
(words/concept/entities) under a hierarchical structure some sort of linguistic
ontology?</div>
<div> </div>
<div>- Are linguistic onotology / information science ontology subjected to only
upper and domain ontology?</div>
<div> </div>
<div>- Any other comments about ontology and wordnet?</div>
<div> </div>
<div>Regards,</div>
<div>liling</div>
