IntroductionOntoNotes Release 4.0, Linguistic Data Consortium (LDC) catalog number LDC2011T03 and isbn 1-58563-574-X, was developed as part of the OntoNotes project, a collaborative effort between BBN Technologies, the University of Colorado, the University of Pennsylvania and the University of Southern California's Information Sciences Institute. The goal of the project is 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). OntoNotes Release 4.0 is supported by the Defense Advance Research Project Agency, GALE Program Contract No. HR0011-06-C-0022. OntoNotes Release 4.0 contains the content of earlier releases -- OntoNotes Release 1.0 LDC2007T21, OntoNotes Release 2.0 LDC2008T04 and OntoNotes Release 3.0 LDC2009T24 -- and adds newswire, broadcast news, broadcast conversation and web data in English and Chinese and newswire data in Arabic. This cumulative publication consists of 2.4 million words as follows: 300k words of Arabic newswire; 250k words of Chinese newswire, 250k words of Chinese broadcast news, 150k words of Chinese broadcast conversation and 150k words of Chinese web text; and 600k words of English newswire, 200k word of English broadcast news, 200k words of English broadcast conversation and 300k words of English web text. The OntoNotes project builds on two time-tested resources, following the Penn Treebank for syntax and the Penn PropBank for predicate-argument structure. Its semantic representation will include word sense disambiguation for nouns and verbs, with each word sense connected to an ontology, and coreference. The current goals call for annotation of over a million words each of English and Chinese, and half a million words of Arabic over five years. DataDocuments describing the annotation guidelines and the routines for deriving various views of the data from the database are included in the documentation directory of this release. The annotation is provided both in separate text files for each annotation layer (Treebank, PropBank, word sense, etc.) and in the form of an integrated relational database (ontonotes-v4.0.sql.gz) with a Python API to provide convenient cross-layer access.
ToolsThis release includes OntoNotes DB Tool v0.999 beta, the tool used to assemble the database from the original annotation files. It can be found in the directory ontonotes-db-tool-v0.999b. This tool can be used to derive various views of the data from the database, and it provides an API that can implement new queries or views. Licensing information for the OntoNotes DB Tool package is included in its source directory.UpdatesAdditional information, updates, bug fixes may be available in the LDC catalog entry for this corpus at LDC2011T03.
