167 FRAME SPECIALISATION MOTIVATED BY INTER-FRAME RELATIONS IN FRAMENET SVETLOZARA LESEVA, IVELINA STOYANOVA, MARIA TODOROVA, HRISTINA KUKOVA Department of Computational Linguistics, Institute for Bulgarian Language, Bulgarian Academy of Sciences {zarka, iva, maria, hristina}@dcl.bas.bg Abstract The paper deals with the conceptual and syntactic specialisation that takes place between more general and more specific or constrained semantic and lexical descriptions as represented in two previously linked resources – FrameNet and WordNet – where lexical units (LUs) instantiating a particular frame in FrameNet are linked to a semantically corresponding synonym set in WordNet. Using the inheritance of conceptual and lexical features as well as other regularities, we observe the modifications that occur in the conceptual and semantic structure between more general and more specific frames and synsets: (1) reducing the number of core frame elements by incorporating one of them in the verb’s meaning; (2) reducing the scope of the frame through imposing stricter selectional restrictions; (3) profiling a different frame element from the one profiled by the hypernym; (4) inclusion/exclusion of frame elements. These types of specialisation are being studied as a point of departure for defining more narrow-scope frames that would allow for more precise predictions about the selectional restrictions and the syntactic realisation of frame elements. Key words — conceptual structure, frame semantics, FrameNet, WordNet 1. Introduction The research presented in this paper is an essential part of our work on enhancing WordNet with information about the conceptual structure of verbs based on the mappings between two large semantic resources, WordNet (WN) and FrameNet (FN). This information includes linking WN synsets with FN frames and providing description of the conceptual elements that receive expression as verbs’ arguments and adjuncts as well as of the selectional restrictions imposed on these elements. Our analysis focuses on the structural features of the resources and the possible structural improvements of FrameNet based on systemic features (e.g., inheritance, causativity, etc.), including definition of new conceptual frames. Section 2 outlines the linguistic resources employed in the proposed research, along with their relevant features as well as the linguistic preliminaries, the motivation for the presented work and how it is situated against the background of previous studies. Section 3 discusses the main factors and procedures for the specification of frames in
