We develop a framework for formalizing semantic construction within grammars expressed in typed feature structure logics, including HPSG. The approach provides an alternative to the lambda calculus; it maintains much of the desirable flexibility of unification-based approaches to composition, while constraining the allowable operations in order to capture(More)
Being able to identify which rhetorical relations (e.g., contrast or explanation) hold between spans of text is important for many natural language processing applications. Using machine learning to obtain a classifier which can distinguish between different relations typically depends on the availability of manually labelled training data, which is very(More)
In this paper we investigate logical metonymy, i.e., constructions where the argument of a word in syntax appears to be different from that argument in logical form (e.g., enjoy the book means enjoy reading the book, and easy problem means a problem that is easy to solve). The systematic variation in the interpretation of such constructions suggests a rich(More)
This paper describes a distributional approach to the semantics of verb-particle constructions (e.g. put up, make off). We report first on a framework for implementing and evaluating such models. We then go on to report on the implementation of some techniques for using statistical models acquired from corpus data to infer the meaning of verb-particle(More)
Research on the discovery of terms from corpora has focused on word sequences whose recurrent occurrence in a corpus is indicative of their terminological status , and has not addressed the issue of discovering terms when data is sparse. This becomes apparent in the case of noun compounding, which is extremely productive: more than half of the candidate(More)
We present an overview of a comprehensive formal theory of the interpretation of sentential fragments, which has as components an empirically validated taxonomy, an analysis of the syntax and compositional semantics of fragments, and a formalisation of their contextual interpretation. We also briefly describe an implementation of this theory, and quantify(More)
In this paper, we explore the interaction between lexical semantics and pragmatics. We argue that linguistic processing is informationally encapsulated and utilises relatively simplètaxonomic' lexical semantic knowledge. On this basis, defeasible lexical generali-sations deliver defeasible parts of logical form. In contrast, pragmatic inference is(More)
