Word-sense Disambiguation - External Knowledge Sources

External Knowledge Sources

Knowledge is a fundamental component of WSD. Knowledge sources provide data which are essential to associate senses with words. They can vary from corpora of texts, either unlabeled or annotated with word senses, to machine-readable dictionaries, thesauri, glossaries, ontologies, etc. They can be classified as follows:

  1. Structured:
    • Thesauri
    • Machine-readable dictionaries (MRDs)
    • Ontologies
  2. Unstructured:
    • Corpora: raw corpora and sense-annotated corpora
    • Collocation resources
    • Other resources (such as word frequency lists, stoplists, domain labels, etc.)

Famous quotes containing the words external, knowledge and/or sources:

    “All violent feelings have the same effect. They produce in us a falseness in all our impressions of external things, which I would generally characterize as the “pathetic fallacy.””
    —John Ruskin (1819–1900)

    ““... Knowledge he shall unwind
    Through victories of the mind,
    Till, clambering at the cradle-side,
    He dreams himself his mother’s pride,
    All knowledge lost in trance
    Of sweeter ignorance.””
    —William Butler Yeats (1865–1939)

    “The sources of poetry are in the spirit seeking completeness.”
    —Muriel Rukeyser (1913–1980)
