This is a moderately broad coverage English lexicon (with about 38,000 lemmas) developed at New York University under LDC sponsorship. It contains detailed information about the syntactic characteristics of each lexical item and is particularly detailed in its treatment of subcategorization (complement structures).


In the current dictionary, nouns have nine possible features and nine possible complements; adjectives have seven features and 14 complements; verbs have five features and 92 complements. The entries for 750 frequent verbs contain 100 tags each, where a tag includes: a pointer to an instance of that verb in a corpus and the subcategorization appropriate for that instance.
