We present an algorithm for anaphora resolution which is a modified and extended version of that developed by (Lappin and Leass, 1994). In contrast to that work, our algorithm does not require in-depth, full, syntactic parsing of text. Instead, with minimal compromise in output quality, the modifications enable the resolution process to work from the output(More)
We describe a methodology and associated software system for the construction of a large lexicon from an existing machine-readable (published) dictionary. The lexicon serves as a component of an English morphological and syntactic analyesr and contains entries with grammatical definitions compatible with the word and sentence grammar employed by the(More)
The design of TimeML as an expressive language for temporal information brings promises, and challenges; in particular, its representational properties raise the bar for traditional information extraction methods applied to the task of text-to-TimeML analysis. A reference corpus, such as TimeBank, is an invaluable asset in this situation; however, certain(More)
Watson reads a clue A. Lally J. M. Prager M. C. McCord B. K. Boguraev S. Patwardhan J. Fan P. Fodor J. Chu-Carroll The first stage of processing in the IBM Watsoni system is to perform a detailed analysis of the question in order to determine what it is asking for and how best to approach answering it. Question analysis uses Watson’s parsing and semantic(More)
M. C. McCord J. W. Murdock B. K. Boguraev Two deep parsing components, an English Slot Grammar (ESG) parser and a predicate-argument structure (PAS) builder, provide core linguistic analyses of both the questions and the text content used by IBM Watsoni to find and hypothesize answers. Specifically, these components are fundamental in question analysis,(More)
