In this paper it is argued that the, accuracy of the syntax-semantics interfhce is improw',d by adopting u non-linear obliqueness hierarchy [br subcategorized arguments. 0...

The paper discusses how compositional semantics is implemented in the Verb- mobil speech-to-speech translation sys- tem using LUD, a description language for underspecified discourse representa- tion structures. The description lan- guage and its formal interpretation in DRT are described as well as its imple- mentation together with the architecture of …...

In many contexts, automatic analyzers cannot fully disambiguate a sentence or an utterance reliably, but can produce ambiguous results containing the correct interpretation. It is useful to study vatious properties of these ambiguities in the view of subsequent total or partial inter- active disambiguation. We have proposed a technique for …...

This paper presents a gratmnar and style checker demonstrator for Span- ish and Greek native writers devel- oped within the project GramCheck. Besides a brief grmnmar error typol- ogy for Spanish, a linguistically moti- vated approach to detection and diag- nosis is presented, based on the gen- eralized use of …...

'Fhis l)aper presents a pruning tech- nique which can bc used to reduce the number of paths searched in rule-based b~g generators of the type proposed by (Poznafiski el; al., 1!)95) and (l'opowMl, 1995). Pruning the search space in these generators is important given the. com- putational cost of bag …...

We describe a case study in tit(', ap- plication of symbolic machinc learning techniques for the discow;ry of linguis- tic rules and categories. A supervised rule induction algorithm is used to learn to predict the. correct dimilmtive suffix given the phonological representation of Dutch nouns. The system produces rules which …...

This paper describes a large-scale sys- tem that performs morphological anal- ysis and generation of on-line Arabic words represented in the standard or- thography, whether fully voweled, par- tially voweled or unw)weled. Analyses display the root, pattern and all other affixes together with feature tags in- dicating part of speech, …...

We describe a number of experiments that demonstrate the usefulness of prosodic information for a processing module which parses spoken utterances with a feature-based grammar employing empty categories. We show that by re- quiring certain prosodic properties from those positions in the input, where the presence of an empty category …...

Knowledge structures called Concel)t (?lustering Knowledge (]raphs (CCKGs) are introduced along with a process for their construction from a machine read- able dictionary. C(3K(]s contain multi- ple concepts interrelated through multi- l)le semantic relations together forming a semantic duster represented by a con-. ceptual graph. '1'he knowledge acquisi- tion is …...

Parsing spontaneous speech is a difficult task because of the ungrammatical nature of most spoken utterances. To overpass this problem, we propose in this paper to handle the spoken language without considering syntax. We describe thus a microsemantic parser which is uniquely based on an associative network of semantic priming. …...

Word sense disambugation has re- cently been utilized in corpus-based aI)- proaches, reflecting the growth in the number of nmehine readable texts. One (:ategory ()f al)l)roa(:hes disambiguates an input verb sense based on the similar- ity t)etween its governing (:its(; fillers and those in given examl)les. In this palter , …...

A new method has been developed for extracting word correspondences from a bilingual corpus. First, the co-occurrence infi~rmation for each word in both languages is extracted li'om the corpus. Then, the correlations between the co-occurrence features of the words are calculated pairwisely with tile assistance of a basic word bilingual …...

. This paper presents a method for the resolution of lexical ambiguity of nouns and its automatic evaluation over the Brown Corpus. The method relies on the use oil' the wide-coverage noun taxonomy of WordNet and the notion of conceptual distance among concepts, captured by a Conceptual Density formula developed …...

We address the problem of automati- cally acquiring case frame patterns (se- lectional patterns) from large corpus data. In particular, we l)ropose a method of learning dependencies between case frame slots. We view the problem of learning case frame patterns as that of learning a multi-dimensional discrete joint distribution, where …...

We address the probhml of automaticMly constructing a thesaurus by clustering words based on corpus data. We view this problem as that of estimating a joint distribution over the (:artesian product of a partition of a set of nouns and a partition of a set of verbs, and propose a …...
