NLP Resources

Software applications related to NLP are in NLP Tools section. In Resoruces we have ontologies/databases and corpora.

Ontologies/DB/Semi-structured

WordNet: Lexical database of English, developed under the direction of George A. Miller. Nouns, verbs, adjectives and adverbs are grouped into sets of cognitive synonyms (synsets), each expressing a distinct concept. Synsets are interlinked by means of conceptual-semantic and lexical relations.

PoS (http://en.wikipedia.org/wiki/Part-of-speech_tagging) tags EAGLES, PAROLE …

A treebank or parsed corpus is a text corpus in which each sentence has been parsed, i.e. annotated with syntactic structure. Syntactic structure is commonly represented as a tree structure, hence the name Treebank. The term Parsed Corpus is often used interchangeably with Treebank: with the emphasis on the primacy of sentences rather than trees.

Treebanks are often created on top of a corpus that has already been annotated with part-of-speech tags. In turn, treebanks are sometimes enhanced with semantic or other linguistic information.

Detects numeric quantities even word spelled ones.
