This paper describes a system that attempts to interpret descriptive texts without the uJe of complex grammars. The purpose of the system is to transform the descriptions to a standard form which may be used as the basis of a database sys- tem knowledgeable in the subject matter of the …...

s Service 2540 Olentangy River Road P.O. Box 3012 Columbus, Ohio 43210 ABSTRACT In an age of increased attention to the problems of database o rganlzat ion, retrieval problems and query languages, one of the major economic problems of many potential databases remains the entry of the original information into …...

The task of understanding unedited naval ship-co-shore messages is implemented in the presence of a large database of domain specific knowledge. The program uses internal syntactic and semantic expectations to analyze the texts and co correct errors that arise during understanding, such as syntactic errors, missing punctuation, and errors of …...

This paper Identifies the types of sentence fragments found In the text of two domains: medical records and Navy equipment status messages. The fragment types are related to full sentence forms on the basis of the elements which were regularly deleted. A breakdown of the fragment types and their distributions …...

A technique is described for performing fitted parsing. After the rules of a more conventional syntactic grammar are unable to produce a parse for an input string, this technique can be used to produce a reasonable approximate parse that can serve as input to the remaining stages of processing. The …...

The work presented here is a preliminary sn~y concerning the automatic translation of French natural language statements into the RESEDA seman- tic metalanguage. The text in natural language is first (pre)processed in order to obtain its syntac- tic structure. The "semantic parsing" process begins with marking the "triggers", defined as …...

Logic based programming systems have enjoyed an increasing popularity in applied AI work in the last few years. One of the contributions to Computational Linguistics made by the Logic Programming Paradigm has been the Definite Clause Grammar. In comparing DCG's wlth previous parsing mechanisms such as ATN's, certain clear advantages …...

Constructing natural language interfaces to computer systems often requires achievment of ad- vanced reasoning and expert capabilities in addition to basic natural language understanding. In this pa- per the above issues are faced in the frame of an actual application concerning the design of a natu- ral language interface for …...

For five years the End-User Friendly Interface to Data management (EUFID) pro- ject team at System Development Corpora- tion worked on the design and implementa- tion of a Natural-Language Interface (NLI) system that was to be independent of both the application and the database management system. In this paper we …...

This paper addresses the problem Of generating communicatively adequate extended responses in the absence of specific knowledge concerning the intensions of the questioner. We formulate and justify a heuristic for the selection of optional deep case slots not contained in the question as candidates for the additional information con- tained …...

In this paper a system which understands and conceptualizes scenes descriptions in natural language is presented. Specifically, the following components of the system are described: the syntac- tic analyzer, based on a Procedural Systemic Gram- mar, the semantic analyzer relying on the Conceptu- al Dependency Theory, and the dictionary. I...

This paper presents a syntactical method of interpreting pronouns in Polish, Using the surface structure of the sentence as well as grammatical and inflexional inlormation accessible during syntactic analysis, an area of reference is marked out for each personal and possessive pronoun. This area consists of a few internal areas …...

This pape~ describes an "intelligent" tutor of foreign language concepts and skills based upon state-of-the-art research in Intelligent reaching Systems and Computational Linguistics. The tutor is part of a large R&D project in ITS which resulted in a system (called DART~ for the de- sign and development of intelligent teaching …...

The paper describes an experimental model of syntactic structure generation starting from the limited fragment of se- mantics that deals with the quantitative values of object parameters. To present the input information the basic semantic units of four types are proposed:"object", "parameter", "function" and "constant". For the syntactic structure representation …...

Island parsing is a powerful technique for parsing with Augmented ~ansition Networks (ATNs) which was developed and successfully applied in the HWIM speech understanding project. The HWIM application grammar did not, however, exploit Woods' original full ATN specification. This paper describes an island parsing interpreter based on HWIM, but containing …...

A new type of machine dictionary is described, which uses terminological relations to build up a semantic network representing the terms of a particular subject field, through interaction with the user. These relations are then used to dynamically generate outline definitions of terms in on-line query mode. The definitions produced …...

In this paper we present a parser which al lows to make explicit the interconnections between syntax and semantics, to analyze the sentences in a quasi-deterministic fashion and, in many cases, to identify the roles of the various constituents even if the sentance is ill-formed. The main fea ture of …...

A set of rules, named CSDC (Conjunct Scope Determination Constraints), is suggested for attacking the conjunct scope problem, the major issue in the automatic processing of conjunctions which has been raising great difficulty for natu- ral language processing systems. Grammars embody- ing the CSDC are incorporated into an existing A~{ …...

In the present paper we argue that the so-called sentence adverbials (typically, adverbs like probably, admittedly,...) should be generated, in the framework of Functional Generative Description, by means of a special deep case - Complementation of Attitude (CA) on grounds of their special behaviour in the topic-focus articulation (TFA) of …...
