TAILIEUCHUNG - Báo cáo khoa học: "Separable Verbs in a Reusable Morphological Dictionary for German"

Separable verbs are verbs with prefixes which, depending on the syntactic context, can occur as one word written together or discontinuously. They occur in languages such as German and Dutch and constitute a problem for NLP because they are lexemes whose forms cannot always be recognized by dictionary lookup on the basis of a text word. Conventional solutions take a mixed lexical and syntactic approach. In this paper, we propose the solution offered by Word Manager, consisting of string-based recognition by means of rules of types also required for periphrastic inflection and clitics. . | Separable Verbs in a Reusable Morphological Dictionary for German Pius ten Hacken1 Stephan Bopp2 Institut fur Informatik IASW Universitãt Basel Petersgraben 51 CH-4051 Basel Switzerland email tenhacken@ 2Lexicologie Faculteit der Letteren Vrije Universiteit De Boelelaan 1105 NL-1081 HV Amsterdam Netherlands email bopp@ Abstract Separable verbs are verbs with prefixes which depending on the syntactic context can occur as one word written together or discontinuously. They occur in languages such as German and Dutch and constitute a problem for NLP because they are lexemes whose forms cannot always be recognized by dictionary lookup on the basis of a text word. Conventional solutions take a mixed lexical and syntactic approach. In this paper we propose the solution offered by Word Manager consisting of string-based recognition by means of rules of types also required for periphrastic inflection and clitics. In this way separable verbs are dealt with as part of the domain of reusable lexical resources. We show how this solution compares favourably with conventional approaches. 1. The Problem In German there exists a large class of verbs which behave like aufhoren stop illustrated in 1 . 1 a. Anna glaubt dass Bernard aufhort. Anna believes that Bernard stops b. Claudia hort jetzt auf. Claudia stops now PRT c. Daniel versucht aufzuhoren. Daniel tries to_stop In subordinate clauses as in la the particle auf and the inflected part of the verb hôrt are written together. In main clauses such as lb the inflected form hôrt is moved by verb-second leaving the particle stranded. In infinitive clauses with the particle ZU to ZU separates the two components of the verb and all three elements are written together. In analysis the problem of separable verbs is to combine the two parts of the verb in contexts such as lb and lc . Such a combination is necessary because syntactic and semantic properties of aufhoren are the same irrespective of whether the two .
