A logic-based environment for developing natural language processing applications

Gérard Milhaud, Élisabeth Godbert (1998)

Mathématiques et Sciences Humaines

We present a system providing a set of tools for developing natural language processing (NLP) applications such as natural language interfaces, communication aid systems, etc. This system is based on two principles: modularity of knowledge representation to ensure the portability of the system, and guided sentence composition to ensure transparency, i.e. to ensure that the produced sentences are well-formed at the lexical, syntactic, semantic and conceptual levels. We first describe the formalisms...

A model of decision with linguistic knowledge.

María Teresa Lamata Jiménez (1994)

Mathware and Soft Computing

The aim of this paper is to develop a new aggregating method for the decision problem in which the possible values of rewards are known in linguistic terms. We show new operators for solving this problem, as well as the way in which OWA operators provide us with an adequate framework for representing the optimism degree of the decision maker in case we have no information about the real state.

A survey of methods to evaluate quantified sentences.

Miguel Delgado, Daniel Sánchez, José María Serrano, M. Amparo Vila (2000)

Mathware and Soft Computing

The evaluation of quantified sentences is used to solve several problems. Most of the methods proposed in the literature are not satisfactory because they do not verify some intuitive properties. In this paper we propose an extension of both possibilistic and probabilistic methods, based on the Sugeno and the Choquet fuzzy integrals respectively, for the evaluation of type II sentences, the most general kind of sentences. These methods verify good properties, and they are shown to be better than...

Applying A Normalized Compression Metric To The Measurement Of Dialect Distance

Simov, Kiril, Osenova, Petya (2007)

Serdica Journal of Computing

The paper discusses the application of a similarity metric based on compression to the measurement of the distance among Bulgarian dia- lects. The similarity metric is de ned on the basis of the notion of Kolmo- gorov complexity of a le (or binary string). The application of Kolmogorov complexity in practice is not possible because its calculation over a le is an undecidable problem. Thus, the actual similarity metric is based on a real life compressor which only approximates the Kolmogorov complexity....

Approches des grammaires catégorielles

Frédérique Segond (1990)

Mathématiques et Sciences Humaines

Étant donné l'importance que prennent les grammaires catégorielles dans le domaine de la linguistique computationnelle, il nous a semblé intéressant de dresser un panorama sur cette question. Nous espérons fournir, aux chercheurs intéressés, un matériau de base susceptible de les aider à approfondir par eux-mêmes le sujet.

Automatic Identification of False Friends in Parallel Corpora: Statistical and Semantic Approach

Nakov, Svetlin (2009)

Serdica Journal of Computing

False friends are pairs of words in two languages that are perceived as similar but have different meanings. We present an improved algorithm for acquiring false friends from sentence-level aligned parallel corpus based on statistical observations of words occurrences and co-occurrences in the parallel sentences. The results are compared with an entirely semantic measure for cross-lingual similarity between words based on using the Web as a corpus through analyzing the words’ local contexts extracted...

Communication with www in Czech

Lukáš Svoboda, Luboš Popelínský (2004)

Kybernetika

This paper describes UIO, a multi–domain question–answering system for the Czech language that looks for answers on the web. UIO exploits two fields, namely natural language interface to databases and question answering. In its current version, UIO can be used for asking questions about train and coach timetables, cinema and theatre performances, about currency exchange rates, name–days and on the Diderot Encyclopaedia. Much effort have been made into making addition of a new domain very easy. No...
