An account of grammatical acquisition is developed within the parameter-setting framework applied to a generalized categorial grammar (GCG). The GCG is embedded in a default inheritance network yielding a natural partial ordering (reeecting generality) of parameters which determines a partial order for parameter setting. Computational simulation shows that… (More)
This paper motivates the use of Information Extraction (IE) for gathering data on protein interactions, describes the customization of an existing IE system, SRI's Highlight, for this task and presents the results of an experiment on unseen Medline abstracts which show that customization to a new domain can be fast, reliable and cost-effective.
an anonymous reviewer for extremely helpful comments on earlier drafts of the m anuscript. This paper describes a new addition to the family of parsing models based on the principles of Description Theory (Marcus, Hindle, & Fleck, 1983). We dem onstrate how the de nition of two simple parsing operations, simple attachm ent and tree lowering, which are… (More)
1 This paper provides an account of deenite and pronominal anaphora which draws together insights from dynamic semantics and situation semantics. The result is a dynamic semantics in which contexts consist of the parts of a scenario which have been brought to a hearer's attention. The contexts are structured by meta-level disjunction, corresponding to a set… (More)
Previous work has demonstrated the success of statistical language models when enough training data is available , but despite that, grammar-based systems are proving the preferred choice in successful commercial systems such as HeyAnita , BeVocal  and Tellme , largely due to the difficulty involved in obtaining a corpus of training data. Here… (More)
The paper describes a parser for Categorial Grammar which provides fully word by word incremental interpretation. The parser does not require fragments of sentences to form constituents, and thereby avoids problems of spurious ambiguity. The paper includes a brief discussion of the relationship between basic Categorial Grammar and other formalisms such as… (More)
Despite the large amount of theoretical work done on non-constituent coordination during the last two decades, many computational systems still treat coordination using adapted parsing strategies, in a similar fashion to the SYSCONJ system developed for ATNs. This paper reviews the theoretical literature, and shows why many of the theoretical accounts… (More)

The production of gold standard corpora is time-consuming and costly. We propose an alternative: the ‚silver standard corpus‗ (SSC), a corpus that has been generated by the harmonisation of the annotations that have been delivered from a selection of annotation systems. The systems have to share the type system for the annotations and the harmonisation… (More)
