TAILIEUCHUNG - Báo cáo khoa học: "A MODEL FOR PREFERENCE"

In this paper we address the problem of choosing the best solution(s) from a set of interpretations of the same object (in our case a segment of text). A notion of preference is stated, based on pairwise comparisons of complete interpretations in order to obtain a partial order among the competing interpretations. An experimental implementation is described, which uses Prolog-like preference statements. | A MODEL FOR PREFERENCE Dominique Petitpierre ISSCO University of Geneva 54 route des Acacias CH-1227 Geneva Switzerland Steven Krauwer Louis des Tombe Instituut voor Algemene Taalwetenschap Rijksuniversiteit Utrecht Trans 14 3512 JK Utrecht The Netherlands Doug Arnold Centre for Cognitive Studies University of Essex Colchester C04 3SQ England Giovanni B.

Box 1907 Luxembourg Luxembourg Abstract In this paper we address the problem of choosing the best solution s from a set of interpretations of the same object in our case a segment of text . A notion of preference is stated based on pairwise comparisons of complete interpretations in order to obtain a partial order among the competing interpretations. An experimental implementation IS described which uses Prolog-like preference statements. 1. Introduction In this paper we address the problem of choosing the best solution s from a set of interpretations of the same text segment For the sake of brevity throughout this text we use the term interpretation where in fact we should write representation of an interpretation . Although developed in the context of a machine translation system the Eurotra project Arnold 1986 Arnold and des Tombe 1987 we believe that our approach is suited to many other fields of computational linguistics and even outside pattern recognition etc. . After a brief overview of the problem section 2 we suggest a general method to deal with preference section 3 and then describe a possible implementation section 4 . An appendix gives actual examples of preference statements. 2. What is preference In the computational linguistics literature the term preference has been used in different contexts. We shall mention a few selectively in section which may be skipped and then state our own view in section . . Various approaches Preference strategies have often been used for dealing with the problem of informed input
