The objectives of this paper are twofold, whereby the computer program is meant to be a particular implementation of a general natural Language [NL] proeessin~ system [NI,PSI which could be used for different domains. The first obiective is to provide a theory for processing temporal information contained in a well-struct- …...

Tree Adjoining Grammar (TAG) is u formalism for natural language grammars. Some of the basic notions of TAG's were introduced in [Jo~hi,Levy, mad Takakashi I~'Sl and by [Jo~hi, l~l. A detailed investigation of the linguistic relevance of TAG's has been carried out in IKroch and Joshi,1985~. In this paper, we …...

This paper analyzes the requirements for adding a temporal reasoning component to a natural language database query system, and proposes a computational model that satisfies those requirements. A prelim- Inary implementation in Prolog is used to generate examples of the model's capabi Iltles. I....

level. The definition of concrete measures is then obtained by assigning actual values to the functional parameters of the abstract definition; some particular cases are shown and discussed in detail. Finally, the task of measuring performance in practice is considered, and a model for experimental performance evaluation is presented. Comparison …...

Elements ot the history, state of the art, and probable future of Machine Translation (MT) are discussed. The treatment is largely tutorial, based on the assumption that this audience is, for the most part, ignorant of matters pertaining to translation in general, and MT in particular. The paper covers some …...

The paper discusses three different kinds of syntactic ill-formedness: ellipsis, conjunctions, and actual syntactic errors. It is shown how a new grammatical formalism, based on a two-level repr_e sentation of the syntactic knowledge is used to cope with Ill-formed sentences. The basic control struc ture of the parser is briefly …...

In this paper we describe a flexible analysls-synthesls system which can be used for a number of studies In speech research. The maln objective Is to have a synthesis system whose characteristics can be controlled through a set of parameters to realize any desired voice characteristics. The basic synthesis scheme …...

By integrating syntactic and semantic processing, our parser (LAZY) is able to deterministically parse sentences which syntactically appear to be garden path sentences although native speakers do not need conscious reanalysis to understand them. LAZY comprises an extension to conceptual analysis which yields an explicit representation of syntactic information and …...

The problem addressed in this paper is to disambiguate grammatically ambiguous input semences by asking the user. who need not be a computer specialist or a linguist, without showing any parse trees or phrase structure rules. Explanation List Comgarison (ELC) is the technique that implements this process. It is applicable …...

In this paper the experience made through the development of a NAtural Language driven Image Generation is discussed. This system is able to imagine a static scene described by means of a sequence of simple phrases. In particular, a theory for equilibrium and support will be outlined together with the …...

Our MT systems integrate many advanced con- cepts from the fields of computer science, linguis- tics, and AI : specialized languages for linguistic programming based on production systems, complete linguistic programming environment, multilevel representations, organization of the lexicons around "lexical units", units of translation of the size of several paragraphs, …...

The papers in this panel consider machine-readable dictionaries from several perspectives: research in computational linguistics and computational lexicology, the development of tools for improving accessibility, the design of lexical reference systems for educational purposes, and applications of machine-readable dictionaries in information science contexts. As background and by way of...

Computational neurolinguistics (CN) is an approach to computational linguistics which in- cludes neurally-motivated constraints in the design of models of natural language processing. Furthermore, the knowledge representations in- cluded in such models must be supported with documented behaviorial ev~ce, normal and patho- logical. This paper will discuss the contribution of …...

The difficulties to be met with the resolu- tion of syntactical ambiguity in MT can be at least partially overcome by means of preserving the syntactical ambiguity of the source language into the target language. An extensive study of the co- rrespondences between the syntactically ambiguous structures in English and …...

We present a progress report on our research on nominal compounds (NC's). Recent approaches to this probiem in linguistics and natural ianguage processing (NLP) are reviewed and criticized. We argue that the notion of "roie nominal", which is at the interface of linguistic and extraiinguis- tic knowledge, is crucial for …...

Generation of texts in natural language requires making conceptual and linguistic decisions. This paper shows first that these decisions involve the use of a discourse grammar, secondly that they are all dependent on one another but that there is a priori no reason to give priority to one decision rather …...

This paper describes the design of a prototype machine translation system for a sublanguage of job advertis~nents. The design is based on the hy- pothesis that specialized linguistic subsystems may require special crmputational treatment and that therefore a relatively shallow analysis of the text may be sufficient for automatic translation …...

In this paper we will present three systems, ATLAS, THAM and VISULEX, which have been designed and implemented at GETA (Study Group for Machine Translation) in collaboration with IFCI (Institut de Formation et de Conseil en Informatique) as tools operating around the ARIANE-78 system. We will describe in turn the …...

One problem for the generation of natural language text is determining when to use a sequence of simple sentences and when a single complex one is more appropriate. In this paper, we show how focus of attention is one factor that influences this decision and describe its implementation in a …...
