Standoff Files

The following additional "standoff" files providing further semantic information to supplement the WordNet 3.0 release. These packages contain the data files as well as documentation on file formats. Note that you must obtain the WordNet database packageseparately.

Use of WordNet in other projects or papers

Please note that WordNet® is a registered tradename. Princeton University makes WordNet available to research and commercial users free of charge provided the terms of our licenseare followed, and proper reference is made to the project using an appropriate citation. Acknowledgement is both required for use of WordNet, and critical to future funding for project maintenance and enhancements.

Semantically Annotated gloss corpus (manually disambiguated)

The semantically annotated gloss corpus is a corpus of manually annotated WordNet synset definitions ("glosses"). We invite you to use this freely available corpus. Please refer to the "Princeton Annotated Gloss Corpus"  in any publications. It can be downloaded from http://wordnet.princeton.edu/glosstag.shtml.

Evocation Database

The "evocation" project collects human judgements on how much one synset brings to mind another. 100,000 semantic similarity judgements from at least three human raters. A ranking of synsets derived from word frequencies in the British National Corpus; synsets have been selected by salience. Download these packages from http://wordnet.cs.princeton.edu/downloads.html.

Morphosemantic Database

Links among noun and verb synsets containing words that share an underlying meaning and are derivationally related. The morphosemantic database (semantic relations between morphologically related nouns and verbs) for WordNet3.0 contains derivational links connecting noun and verb senses, e.g., employment#n1-employ#v2. morphosemantic-links.xls repeats these links, but also give the semantic type of the relationship. The database uses 14 semantic relations, as listed in the README file, and can be downloaded from http://wordnetcode.princeton.edu/standoff-files/morphosemantic-links.xls.

Telelogical Database

The teleological database contains, for approximately 350 artifacts (nouns), an encoding of the typical activity (purpose) for which that artifact was intended. 11 semantic relations are used to encode that activity, as listed in the README file and can be downloaded from http://wordnetcode.princeton.edu/standoff-files/teleological-links.xls.

"Core" WordNet

A semi-automatically compiled list of 5000 "core" word senses in WordNet (approximately the 5000 most frequently used word senses, followed by some manual filtering and adjustment) can be downloaded from http://wordnetcode.princeton.edu/standoff-files/core-wordnet.txt.

Logical Forms of the Glosses (Core WordNet Nouns)

Logical forms for the glosses of the ~2800 noun senses in core WordNet, in plain text format, using eventuality notation. Generated by USC/ISI, California in 2007. These are generally of higher quality than those contained in the file below for all glosses.  Download from http://wordnetcode.princeton.edu/standoff-files/cwn-noun-lfs.txt.
