This publication provides vital effects from the ESPRIT undertaking 393 "Construction and Interrogation of information Bases utilizing typical Language textual content and images" (ACORD). The venture concerned greater than fifty humans overfive years, and integrated commercial and educational companions from 3 nations. the most results of the venture is a hugely refined human-machine interface permitting the development and interrogation of a standard wisdom base in English, French, and German, utilizing either usual language and portraits. bankruptcy 1 offers an summary of the venture. Chapters 2-4 increase particular matters touching on thegrammar types used (functional grammars and unification categorial grammars). bankruptcy five discusses anaphora answer and bankruptcy 6 textual content new release. bankruptcy 7 explains the combination of textual content and pix, and bankruptcy eight discusses the data base module. The contributions are theoretically orientated and strongly involved in generalization and the underlying historical past of power additional advancements.

The combination procedure deals precisely with the relationship between sets of valencies, and it can be stated in the following general form : (20) (VA - VFAS U VF = VR) where VR is the valencies set of the result V-l is the valencies set of the argument VFAS is the valencies set of the functor's active sign VF is the valencies set of the functor It is easy to verify that the derivation of Ie regarde in (12) corresponds to the following operationS (21) ({obj, nom, mod} - {obj}) U {} = {nom, mod} In other words, for the two signs to be concatenated, a valency of the argument must be consumed.

Cplicitly what the coverage of a parser or a generator is. Demos and actual specifications are, at best, hints indicating roughly what the system can or should be capable of. When a lot of money is spent in the implementation of grammars and parsers, it is a big disappointment to find in a haphazard way obvious but completely unforeseen counterexamples to some system. 'Camples which 'work' say very little about the descriptive power of the grammar. Control of grammars can thus contribute to enhance the reliability of NL products and to monitor extensions of their coverage.

O [ne ... J The derivation of ne regarde corresponds thus to (23), where the valencies set of the verb remains unchanged: (23) ({obj, nom, mod} - 0) U {} = {obj, nom, mod} Another case is illustrated by the reflexive se, which must consume an object valency and agree with the nominative valency : (24) se: C/(C {(nom, G:N:p3), (obj, G:N:p3)} [verb ...
