Message 1: New Corpus from the Linguistic Data Consortium

Subject: New Corpus from the Linguistic Data Consortium



 Announcing a NEW RELEASE from the
 LINGUISTIC DATA CONSORTIUM

 DSO CORPUS OF SENSE-TAGGED ENGLISH NOUNS AND VERBS

This corpus contains sense-tagged word occurrences for 121 nouns and
70 verbs which are among the most frequently occurring and ambiguous
words in English. These occurrences are provided in about 192,800
sentences taken from the Brown corpus and the Wall Street Journal, and
have been hand tagged by students at the Linguistics Program of the
National University of Singapore. WordNet 1.5 sense definitions of
these nouns and verbs were used to identify a word sense for each
occurrence of each word.

In addition to providing the word occurrences in their full sentential
context, the corpus includes complete listings of the WordNet 1.5
sense definitions used in the tagging.

The following example illustrates the format of a sentence with a
sense tag for the word "action", followed by the corresponding
WordNet1.5 sense definition:

 ca01.db #020 `` These >> actions 8 << should serve to protect in
 fact and in effect the court 's wards from undue costs and its
 appointed and elected servants from unmeritorious criticisms ''
 , the jury said .

 Sense 8
 legal action, action, case, lawsuit, suit -- (a judicial proceeding
 brought by one party against another; "no criminal cases were heard
 while the judge was ill")
 => proceeding, legal proceeding, judicial proceeding,
 proceedings -- (the institution of a legal action)
 => due process, due process of law -- (the administration
 of justice according to established rules and principles)
 => group action -- (action taken by a group of people)
 => act, human action, human activity -- (something
 that people do or cause to happen)

(In the actual corpus, all tagged occurrences of a given noun or verb
are stored together in one file, with each full sentence on one line;
all noun and verb word sense definitions are stored together in two
separate files.)

This sense tagged corpus was provided by Hwee Tou Ng of the Defence
Science Organisation (DSO) of Singapore. It was first reported in the
following paper at ACL-96:

"Integrating Multiple Knowledge Sources to Disambiguate Word Sense:
 An Exemplar-Based Approach," by Hwee Tou Ng and Hian Beng Lee, in
 Proceedings of the 34th Annual Meeting of the Association for
 Computational Linguistics, pages 40-47, Santa Cruz, California, USA,
 June 1996. ( http://xxx.lanl.gov/abs/cmp-lg/9606032 )
