Synopsis

The topic of this book is the theoretical foundations of a theory LSLT -- Lexical Semantic Language Theory - and its implementation in a the system for text analysis and understanding called GETARUN, developed at the University of Venice, Laboratory of Computational Linguistics, Department of Language Sciences. LSLT encompasses a psycholinguistic theory of the way the language faculty works, a grammatical theory of the way in which sentences are analysed and generated -- for this we will be using Lexical-Functional Grammar -- a semantic theory of the way in which meaning is encoded and expressed in utterances -- for this we will be using Situation Semantics -, and a parsing theory of the way in which components of the theory interact in a common architecture to produce the needed language representation to be eventually spoken aloud or interpreted by the phonetic/acoustic language interface. LSLT will then be put to use to show how discourse relations are mapped automatically from text using the tools available in the 4 sub-theories, and in particular we will focus on Causal Relations showing how the various sub-theories contribute to address different types of causality.

About this title

Synopsis

The topic of this book is the theoretical foundations of a theory LSLT - Lexical Semantic Language Theory - and its implementation in a the system for text analysis and understanding. There are two main tenets of the theory which are supporting the construction of the system is that it is possible to reduce access to domain world knowledge by means of contextual reasoning, i.e. reasoning triggered independently by contextual or linguistic features of the text under analysis. In other words, it adopts what could be termed the Shallow Processing Hypothesis: access to WordNet is reduced and substituted whenever links are missing through inferences on the basis of hand-coded lexical and grammatical knowledge given to the system, which are worked out in a fully general manner.The purpose of the book is to present in detail the scientific foundations of the architecture and components of a (yet to be) implemented system for text understanding and generation, and at the same time to discuss critically some of the possible applications in real world domains in which such an approach could be fruitful.
