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:
- Structured:
- Thesauri
- Machine-readable dictionaries (MRDs)
- Ontologies
- 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 Great Society is a place where every child can find knowledge to enrich his mind and to enlarge his talents.... It is a place where the city of man serves not only the needs of the body and the demands of commerce but the desire for beauty and the hunger for community.... It is a place where men are more concerned with the quality of their goals than the quantity of their goods.”
—Lyndon Baines Johnson (1908–1973)
“The sources of poetry are in the spirit seeking completeness.”
—Muriel Rukeyser (1913–1980)
