Metaphors for Linguistic Description of Data

Abstract

In this paper, we propose a formal representation of the meaning of sentences involving conceptual metaphors in the context of the research line of Computing with Words and Perceptions. Conceptual metaphors are mappings between conceptual domains that are common in everyday natural language usage. They are not just a matter of lexico-grammar stratum but of representation and processing in the semantic stratum of language. Here, the Granular Linguistic Model of a Phenomenon is presented as a computational paradigm for representing the meaning of metaphorical sentences, with an application devoted to generate linguistic descriptions of data. The obtained results provide an approach to assign a fuzzy fulfilment degree to linguistic expressions with a more complex semantic and lexico-grammar structure than usually handled in Fuzzy Logic.
