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:

    “The ideal of brotherhood of man, the building of the Just City, is one that cannot be discarded without lifelong feelings of disappointment and loss. But, if we are to live in the real world, discard it we must. Its very nobility makes the results of its breakdown doubly horrifying, and it breaks down, as it always will, not by some external agency but because it cannot work.”
    —Kingsley Amis (1922–1995)

    “The endless cycle of idea and action,
    Endless invention, endless experiment,
    Brings knowledge of motion, but not of stillness;
    Knowledge of speech, but not of silence;
    Knowledge of words, and ignorance of the Word.
    All our knowledge brings us nearer to our ignorance.”
    —T.S. (Thomas Stearns)

    “On board ship there are many sources of joy of which the land knows nothing. You may flirt and dance at sixty; and if you are awkward in the turn of a valse, you may put it down to the motion of the ship. You need wear no gloves, and may drink your soda-and-brandy without being ashamed of it.”
    —Anthony Trollope (1815–1882)
