this article can compute solutions to all four of these problems in a single flamework, with a number of additional advantages over previously presented isolated solutions

This thesis proposes a strongly lexicalist approach to machine translation and applies it to the translation of spatial prepositions and prepositional expressions between English and Spanish. Bilingual contrastive knowledge resides solely in the bilingual lexicon and is structured in the form of correspondences between sets of source and target language lexemes related through indices. The resulting architecture maximizes the independence of the monolingual and bilingual components. This independence is demonstrated by developing a grammar of Spanish which is significantly different in its constructions from its analogous English grammar. In particular, relative clauses are analysed through a single rule that allows gaps in subject position, while clitic climbing and doubling are handled through mechanisms not normally found in grammatical descriptions of English. Bilingual lexical rules, in conjunction with the bilingual lexicon, constitute a single, motivated and well defined mechani...

This paper describes a natural language-based CASE tool called CM-Builder which aims at supporting the Analysis stage of software development in an Object-Oriented framework. CM-Builder uses robust Natural Language Processing techniques to analyse software requirements texts written in English and build an integrated discourse model of the processed text, represented in a Semantic Network. This Semantic Network is then used to automatically construct an initial UML Class Model representing the object classes mentioned in the text and the relationships among them. The initial model can be directly input to a graphical CASE tool for further refinement by a human analyst. CM-Builder has been quantitatively evaluated in blind trials against a collection of unseen software requirements texts and we present the results of this evaluation, together with the evaluation methodology. The results are very encouraging and demonstrate that tools such as CM-Builder have the potential to play an important role in the software development process.

L 0 constitutes a recent effort in Cognitive Science to build a natural language acquisition system for a limited visual domain. As a preparatory step towards addressing the issue of learning in this domain, we have built a set of tools for rapid prototyping and experimentation in the areas of language processing, image processing, and knowledge representation. The special focus of our work was the integration of these different components into a flexible system which would allow us to better understand the domain given by L 0 and experiment with alternative approaches to the problems it poses. 1 Supported by an IBM Graduate Fellowship. 1 Introduction The Miniature Language Acquisition (MLA) task is easy to describe yet difficult to solve. The task is to learn a natural language fragment given training input consisting of simple geometric scenes accompanied by partial descriptions in the language of choice. Figure 1 shows an example of an input picture, along with several partial d...

• Goal: To provide an overview of the historical development of dependency grammar, set within the context of theoretical linguistics. • History in overview

This document describes LaSIE version 2.1 as embedded within GATE version 1.5.1. It is a technical specication document, not a user guide. It documents each of the modules in LaSIE in terms of: a functional overview, its interface to GATE (annotation input from or output to the GATE document manager), external processes the module may invoke, external resources on which the module depends, and known limitations.

This paper will thus examine the pros and cons of Prolog from the perspective of a natural language researcher, concluding that the recent advances in logic programming embodied in Prolog should provide an important impetus for further progress in the application of logic programming techniques to natural language analysis.
