<DIV>Dear Michal, dear All,</DIV>
<DIV> </DIV>
<DIV>I think the hierarchy of precision is to show the boundary between shared
vocabularies. Lexicons, classifications and thesauri are shared vocabularies,
but not precise enough to be called ontologies in the sense used in information
science. Whether WornNet is an ontology, or not is related to the question where
to put the boundary. But we already have many opinions within the discussion,
thus, various people could accept the most suitable opinion for them. </DIV>
<DIV> </DIV>
<DIV>With best regards,</DIV>
<DIV> </DIV>

<DIV>This definition makes me wonder - what is NOT an ontology? If even a simple
lexicon is also an ontology, most of papers in NLP and CL describe research with
the use of ontologies, even unintentionally. </DIV>

<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>

[Corpora-List] WordNet vs Ontology</FONT></FONT></DIV></DIV></DIV>
<DIV> </DIV></DIV>
<DIV style="TEXT-DECORATION: ; FONT-FAMILY: ; COLOR: ; DISPLAY: inline">
<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>
