OBJECTIVE Construction of a resource that provides semantic information about words and phrases to facilitate the computer processing of medical narrative. DESIGN Lexemes (words and word phrases) in the Specialist Lexicon were matched against strings in the 1997 Metathesaurus of the Unified Medical Language System (UMLS) developed by the National Library of Medicine. This yielded a "semantic ...

We propose a method for automatic fine-scale audio description that draws inspiration from ontological sound description methods such as Shaeffer’s Objets Sonores and Smalley’s Spectromorphology. Our goal is complete automation of audio description at the level of sound objects for indexing and retrieving sound segments within Internet audio documents. To automatically segment audio documents i...

Automatic grammar extraction from annotated corpora (Xia, 1999; Chen and Vijay-Shanker, 2000; Chiang, 2000; Hockenmaier and Steedman, 2002; Miyao et al., 2004) enabled us to build a widecoverage lexicalized grammar at low cost. They succeeded in extracting a large number of lexical entries with less effort while conventional methods only allow limited lexical entries to be acquired in realworld...

This paper discusses the effects of variation in the meaning of property concept terms (Dixon 1982) on the form of predicative and comparative constructions. We demonstrate the existence of two kinds of property concept lexeme, which differ systematically in how they participate in constructions expressing the truth conditions of property concept predication. The first kind of lexeme is used in...

A writer independent handwriting recognition system must be able to recognize a wide variety of handwriting styles, while attempting to obtain a high degree of accuracy when recognizing data from any one of those styles. As the number of writing styles increases, so does the variability of the data’s distribution. We then have an optimization problem: how to best model the data, while keeping t...
