The HPSG grammars we are using, closely resemble the proposals in [Pollard and Sag, 1987]. As far as the coding of the lexical functions is concerned, we have simply interpreted these as relation names. 3 Representation The main aim of the ET-10/?5 project, 'Collocations and the Lexicalisation of Semantic Operations '1, is to evaluate the use of Mel'~uk's analysis of collocations in terms of lexical functions 2, as an interlingun device in a machine translation system. In this poster we only point out the main design issues involved in encoding the essential parts of this analysis in an HPSG-style. | A Constraint-based Representation Scheme of Collocational Structures Dirk Heylenf André Schenkf Marc VerhagenỊ heylen@let.ruu.nl schenk@let.ruu.nl verhm@sx.ac.uk _ __ t OTS - TYans 10- 3512 JK Utrecht NL í CLMT Essex University - Wivenhoe Park - C04 3SQ Colchester UK 1 Introduction The main aim of the ET-10 75 project Collocations and the Lexicalisation of Semantic Operations 1 is to evaluate the use of Mel cuk s analysis of collocations in terms of lexical functions2 as an interlingua device in a machine translation system. In this poster we only point out the main design issues involved in encoding the essential parts of this analysis in an HPSG-style framework. Other aspects of the project such as the definition of collocations or the evaluation of the analysis as such will not be dealt with. The linguistic analysis of collocations as far as it is dealt with in this poster involves two major issues. Coding the Mel cukian analysis in an HPSG-like grammar. Designing the architecture of the lexicon. 2 Analysis Examples of the collocational structures we have in mind are strong criticism as an adjective-noun combination and give a demonstration as a verb-noun combination . The essential characteristics we want to account for in our analysis are the following. The collocational cooccurrence restriction. The dependence of the meaning of the collocate on the combination. The relation between the collocate occurrence of a word and its free occurrence. Following Mel cuk the restricted choice of the particular adjective or verb is represented in the dictionary by means of lexical functions. The dictionary entry for criticism contains a section in which its collocates are listed indexed by a lexical function. In this case we would find Magn cnZiCism strong. This points out that you can use strong when you want to express Magn criticism . In our interpretation of these lexical functions we take them to be general semantic operations representing the major semantic .
