   Abstract

Causality plays and has played an important role in human cognition, in particular in human decision-making, providing a basis for choosing an action which is likely to lead to a desired result. In this seminar, we present a method for detecting, retrieving and classifying conditional and causal sentences, particularly those identified by the presence of certain interrogative particles. These sentences are pre-processed to obtain cause-effect structures and causal chains. The result is displayed in an imperfect causal graph, which will be the basis for other applications like Question Answering and rule-based systems or generation of automated summaries.

In this same scope, but from a different point of view, Fuzzy Deformable Prototypes (from now on FDPs), introduced by J. A. Olivas in 2001, come from the confluence of two interesting approaches to the concept of prototype: the “deformable prototypes” of Bremermann, introduced in the late seventies from the field of pattern recognition, and fuzzy prototypes of Zadeh, result of a controversy with cognitive psychologists. In the framework of ‘deformable prototypes’ a real element is classified according to the minimum energies required for physically deforming the closest prototype. For Zadeh, a fuzzy prototype is not an element - usually the best representative of a set or class - but a reunion of good, bad and borderline elements of a category. Many applications of this approach had been accomplished, such as the ones related to Information Systems and Software Engineering ones, traffic control, health records and documents management, social sciences or Information Retrieval and Web Search.
