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 law is only one of several imperfect and more or less external ways of defending what is better in life against what is worse. By itself, the law can never create anything better.... Establishing respect for the law does not automatically ensure a better life for that, after all, is a job for people and not for laws and institutions.”
—Václav Havel (b. 1936)
“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)
“Even healthy families need outside sources of moral guidance to keep those tensions from imploding—and this means, among other things, a public philosophy of gender equality and concern for child welfare. When instead the larger culture aggrandizes wife beaters, degrades women or nods approvingly at child slappers, the family gets a little more dangerous for everyone, and so, inevitably, does the larger world.”
—Barbara Ehrenreich (20th century)
