TAILIEUCHUNG - Báo cáo khoa học: compositional account of the semantics of German prefix verbs

A compositional account of the semantics of German prefix verbs in HPSG is outlined. We consider only those verbs that are formed by productive synchronic rules. Rules are fully productive if they apply to all base verbs which satisfy a common description. Prefixes can be polysemous and have separate, highly underspecified lexical entries. Adequate bases are determined via selection restrictions. | Compositional Semantics of German Prefix Verbs Maria Wolters Institut fur Kommunikationsforschung und Phonetik University of Bonn Poppelsdorfer Allee 47 D-Õ311Õ Bonn mwo@ Abstract A compositional account of the semantics of German prefix verbs in HPSG is outlined. We consider only those verbs that are formed by productive synchronic rules. Rules are fully productive if they apply to all base verbs which satisfy a common description. Prefixes can be polysemous and have separate highly underspecified lexical entries. Adequate bases are determined via selection restrictions. 1 The Problem Determining the semantics of unknown words which can be derived from lexicon entries is highly desirable for natural language understanding Light 1996 . In this paper I sketch a compositional account of the semantics of German prefix verbs derived from a verbal base concentrating on those verbs that can be generated by a productive word formation rule. Like Witte 1997 I assume that the meaning of most of these verbs can be derived compositionally by unifying the semantic representations of its constituents. Example 1 durch laufen through to run durchlaufen to run through This is an instance of a common rule which can be summarized informally as 2 dutch VERB motion agentive VERB through a space When a prefix verb is lexicalized its meaning frequently shifts due to language change and metaphorical usage Mayo et al. 1995 . For example durch-laufen is mostly associated with the meaning passing through ail stages of a process 3 Er durchlauft die Schulung. He passes through the training. 2 The Semantics of Prefix Verbs Frequently the prefix modifies features of the base verb such as valency or aspect1. For example while eilen to haste is an activity etw. durcheilen to haste through sth. is an accomplishment. I assume that the prefix entry provides a highly underspecified blueprint of the structure of the prefix verb therefore I regard the prefix as the head of the .
