CiNii 図書 - The Core language engine

The Core Language Engine presents the theoretical and engineering advances embodied in one of the most comprehensive natural language processing systems designed to date. Recent research results from different areas of computational linguistics are integrated into a single elegant design with potential for application to tasks ranging from machine translation to information system interfaces. Bridging the gap between theoretical and implementation oriented literature, The Core Language Engine describes novel analyses and techniques developed by the contributors at SRI International's Cambridge Computer Science Research Centre. It spans topics that include a wide-coverage unification grammar for English syntax and semantics, context-dependent and contextually disambiguated logical form representations, interactive translation, efficient algorithms for parsing and generation, and mechanisms for quantifier scoping, reference resolution, and lexical acquisition. Contents Introduction to the CLE * Logical Forms * Categories and Rules * Unification Based Syntactic Analysis * Semantic Rules for English * Lexical Analysis * Syntactic and Semantic Processing * Quantifier Scopin * Sortal Restrictions * Resolving Quasi Logical Forms * Lexical Acquisition * The CLE in Application Development * Ellipsis, Comparatives, and Generation * Swedish-English QLF Translation

categories and rules, Hiyan Alshawi - constraints, components and rules, categories for linguistic analysis, CLE categories, category unification and subsumption, Boolean expression feature values, feature sets, defaults and macros, internal category representation, grammar rules, syntax and morphology rules, semantic rules, lexical entries
unification-based syntactic analysis, Stephen G. Pulman - theoretical background, subcategorization, start categories, sentence types, subject-auxilliary inversion, unbounded dependencies, passives, conjunctions
semantic rules for English, Jan van Eijck and Robert C. Moore - semantic rules and sences, general principles of the CLE semantics, the semantics of specific constructions
lexical analysis, David Carter - tokenizing the input, segmenting the tokens, recovering from unknown tokens
syntactic and semantic processing, Robert C. Moore and Hiyan Alshawi - parsing, semantic analysis, morphological processing, ambiguities and packing
quantifier scoping, Douglas B. Moran and Fernando C.N. Pereira - quantifier scoping problem, scoping rules and references, the scoping algorithm, refinements to the basic algorithm, implementation
sortal restrictions, Hiyan Alshawi and David Carter - applying sortal restrictions, encoding sorts as terms, the external representation of sorts, specifying the sort hierarchy, developments
resolving quasi logical forms, Hiyan Alshawi - deriving LFs from QLFs, anaphoric terms, context model, constraints on resolved LFs, anaphoric relations and formulae, further work on QLF resolution
lexical acquisition, David Carter - strategy adopted, assumptions behind the strategy

the CLE in application development, Arnold Smith - linguistic applications, model-based systems, the LF-Prolog query evaluator, the order-processing exemplar, extending the interface, new directions
ellipsis, comparatives and generation, Hiyan Alshawi and Stephen G. Pulman
Swedish-English QLF translation, Hiyan Alshawi, et al - the Swedish CLE, QLF-based translation, disambiguation and interaction.
