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.)

“Many are poets but without the name,
For what is poesy but to create
From overfeeling good or ill; and aim
At an external life beyond our fate,
And be the new Prometheus of new men.”
—George Gordon Noel Byron (1788–1824)
“It destroyed him and your mother, because he ventured into areas of knowledge where man is not meant to go.”

“I count him a great man who inhabits a higher sphere of thought, into which other men rise with labor and difficulty; he has but to open his eyes to see things in a true light, and in large relations; whilst they must make painful corrections, and keep a vigilant eye on many sources of error.”
—Ralph Waldo Emerson (1803–1882)
