The FrameNet project has developed a lexical knowledge base providing a unique level of detail as to the the possible syntactic realizations of the specific semantic roles evoked by each predicator, for roughly 7,000 lexical units, on the basis of annotating more than 100,000 example sentences extracted from corpora. An interim version of the FrameNet data was released in October, 2002 and is being widely used. | The FrameNet Data and Software Collin F. Baker International Computer Science Institute Berkeley California USA collinb@ Hiroaki Sato Senshu University Kawasaki Japan hiroaki@ Abstract The FrameNet project has developed a lexical knowledge base providing a unique level of detail as to the the possible syntactic realizations of the specific semantic roles evoked by each predicator for roughly 7 000 lexical units on the basis of annotating more than 100 000 example sentences extracted from corpora. An interim version of the FrameNet data was released in October 2002 and is being widely used. A new more portable version of the FrameNet software is also being made available to researchers elsewhere including the Spanish FrameNet project. This demo and poster will briefly explain the principles of Frame Semantics and demonstrate the new unified tools for lexicon building and annotation and also FrameSQL a search tool for finding patterns in annotated sentences. We will discuss the content and format of the data releases and how the software and data can be used by other NLP researchers. 1 Introduction FrameNet1 Fontenelle 2003 Fillmore 2002 Baker et al. 1998 is a lexicographic research project which aims to produce a lexicon containing very detailed information about the relation be 1http framenet tween the semantics and the syntax of predicators including verbs nouns and adjectives for a substantial subset of English. The basic unit of analysis is the semantic frame defined as a type of event or state and the participants and props associated with it which we call frame elements FEs .2 Frames range from highly abstract to quite specific. An example of an abstract frame would be the Replacement frame with FEs such as Old and New as in the sentence Pat replaced l Old the curtains New with wooden blinds . One sense of the verb replace is associated with the Replacement frame thus constituting one lexical unit .
