  • Natural language processing-a psychological perspective

    Publication Year: 1988, Page(s):1/1 - 1/4

    The paper is concerned with the characteristics of an ideal natural language understanding system. It is suggested that in addition to processing new linguistic input, such a system should be capable of monitoring the output from a natural language generating (NLG) component in a comprehensive system. In order to perform these two functions efficiently, it is argued that the NLU system should proc... View full abstract»

  • A natural language interface to planning systems

    It is characteristic of the type of interaction that one would like to be able to have with a planner that the range and type of potential queries is not predictable in advance, and thus not reducible to choices within some predetermined set of options. Furthermore, it is often desirable to have the planner try out a range of hypothetical or counterfactual situations that could not be represented ... View full abstract»

  • Generating natural language descriptions of derived relations

    Publication Year: 1988, Page(s):2/1 - 2/3

    Users of a formal language system face the problem of ensuring that their syntactically-valid constructions in that language are valid reflections of their semantic intentions. The work described develops a method for validating relational algebra query language expressions put to a relational database, through the automatic generation of natural language descriptions of the relations derived by q...

  • A natural language system and its users

    Describes the results of an ICL-internal project to produce a natural enquiry language system (NEL) by adding a PROLOG front-end to Querymaster, the standard ICL program for querying information stored in a database. Querymaster runs under VME on the ICL 2900 series and Series 39 computers. It provides access to various types of database including IDMS and conventional files, using CAFS (content a...

  • The use of reasoning in natural language understanding

    Publication Year: 1988, Page(s):3/1 - 3/5

    A connection between the problem of natural language understanding and representation of knowledge is outlined. An example is considered, of finding a substitute for a hammer, indicating the problems that this creates in representing the required knowledge. A solution is suggested which combines the needs of the expressiveness of the representation with those of the underlying reasoning techniques View full abstract»

  • Natural language for modelling situations

    The notion of event suggests time dependence: something has happened, and it is the pertinent conditions which make such an occurrence possible. The totality of these pertinent conditions is called a situation. The principle of causality having been accepted, all situations are subject to logic. However, the logic of situations is not always immediately apparent. On the other hand, natural languag... View full abstract»

  • Making sense of corrupt input: contextual interpretation in LOQUI

    Publication Year: 1988, Page(s):4/1 - 4/5

    LOQUI is the name of a natural language interface to databases developed during the course of the ESPRIT project LOKI. LOQUI is written in BIM prolog. The purpose of the paper is to illustrate LOQUI's exploitation of context in its treatment of corrupt input. This is an important issue in LOQUI, since the system has been designed to have a rich dialogue capability that will allow conversations to ... View full abstract»

    Describes completed work on the implementation of two successive versions of a natural language database interface with some recovery facilities, using the Prolog DCG in a way analogous to Hendrix's LIFER system (1978) and ongoing work building similar facilities into a more linguistically sophisticated interface View full abstract»
