Description

Taken from the corpus description (see link above):

OntoNotes Release 5.0 is the final release of the OntoNotes project, a collaborative effort between BBN Technologies, the University of Colorado, the University of Pennsylvania and the University of Southern Californias Information Sciences Institute. The goal of the project was to annotate a large corpus comprising various genres of text (news, conversational telephone speech, weblogs, usenet newsgroups, broadcast, talk shows) in three languages (English, Chinese, and Arabic) with structural information (syntax and predicate argument structure) and shallow semantics (word sense linked to an ontology and coreference).

Specific guidelines:

• Constituent syntax trees and tagging
• Coreference
• NER

Domains and Genres

• broadcast news
• broadcast conversation
• news
• religious
• telephone
• web
