Naming Qualitative Models Based on Intervals: A General Framework

Ester Martinez-Martin, M. Teresa Escrig, Angel P. del Pobil

Abstract


Mostly real-daily problems involve qualitative reasoning about space and/or time. In fact, naming qualitative models are those that allow humans to express spatio-temporal concepts such as The cinemas are far away from my house, That horse is really fast or Take care, the car in front of you is reducing its speed. In colloquial terms, naming concepts are called relative. In this paper we introduce a general way to define naming qualitative models consisting of: (1) a representation magnitude, (2) the basic step of inference process and (3) the complete inference process. That is, we present a general framework to solve the representation magnitude and the basic step of inference process of qualitative models
based on intervals. This general procedure is based on the definition of two algorithms: the qualitative sum and the qualitative difference.
