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:
“A State, in idea, is the opposite of a Church. A State regards classes, and not individuals; and it estimates classes, not by internal merit, but external accidents, as property, birth, etc. But a church does the reverse of this, and disregards all external accidents, and looks at men as individual persons, allowing no gradations of ranks, but such as greater or less wisdom, learning, and holiness ought to confer. A Church is, therefore, in idea, the only pure democracy.”
—Samuel Taylor Coleridge (1772–1834)
“Is there something in trade that dessicates and flattens out, that turns men into dried leaves at the age of forty? Certainly there is. It is not due to trade but to intensity of self- seeking, combined with narrowness of occupation.... Business has destroyed the very knowledge in us of all other natural forces except business.”
—John Jay Chapman (1862–1933)
“My profession brought me in contact with various minds. Earnest, serious discussion on the condition of woman enlivened my business room; failures of banks, no dividends from railroads, defalcations of all kinds, public and private, widows and orphans and unmarried women beggared by the dishonesty, or the mismanagement of men, were fruitful sources of conversation; confidence in man as a protector was evidently losing ground, and women were beginning to see that they must protect themselves.”
—Harriot K. Hunt (1805–1875)
