overview
Overview
  • Lexical Markup Framework (LMF)
    • Motivation, Model, Example
  • LingInfo
    • Motivation, Model, Example
  • Discussion
lmf motivation
LMF Motivation
  • Provide a common model for the creation and use of lexical resources
  • Manage the exchange of data between and among these resources
  • Enable the merging of individual electronic resources to form extensive global electronic resources
linginfo motivation
LingInfo Motivation
  • Lexicalized Ontologies
    • Representation of terms instead of ontology class labels
    • Lexical (morphosyntactic) information for such terms – to handle morphological& syntactic term variations and disambiguation
    • (Lexical) Semantics is strictly in the (domain) ontology
  • Lexical Ontology Enrichment
    • Increasing number of ontologies published on (Semantic) Web
    • Reuse of knowledge in semantic annotation, ontology-based information extraction, question answering, etc.
    • Enrichment/integration of ontologies with lexical knowledge – terminology, synonyms, translations, morphosyntactic information

Lexical Enrichment
  • Derive synonyms from WordNet
    • Check if class names are lexical entries in WordNet
    • Extract synonyms from corresponding synsets
    • Sense Disambiguation (pick the right synset)
  • Derive translations from Wikipedia
    • Check if class names correspond to Wikipedia pages
    • Extract translations through “Interlanguage links“
    • Sense Disambiguation
  • Derive morphosyntactic information from corpora
    • Reverse engineer the lexicon behind PoS-tagger / Morph Analyzer (advantage: disambiguation in context)
