To treat dynamic preferences correctly is crucially required in the fields of argumentation as well as nonmonotonic reasoning. To meet such requirements, first, we propose a hierarchical Prioritized logic Program (or a hierarchical PLP, for short), which enhances the formalism of Sakama and Inoue's PLP so that it can represent and reason about dynamic preferences. Second, using such a hierarchical PLP as the underlying language, the proposed method defines the preference-based argumentation framework (called the dynamic PAP) built from it. this enables us to argue and reason about dynamic preferences in argumentation. Finally we show the interesting relationship between semantics of a hierarchical PLP given by preferred answer sets and semantics of the dynamic PAF given by P-extensions.

Clinical Decision Support Systems (CDSS) are useful tools that aid physicians during different tasks such as diagnosis, treatment and patient monitoring. Multidisciplinary, heterogeneous and disperse clinical information and decision criteria have to be handled by CDSSs. For such tasks, Knowledge Engineering (KE) techniques and semantic technologies are very suitable, as they support (i) the integration of heterogeneous knowledge, (ii) the expression of rich and well-defined models for knowledge aggregation, and (iii) the application of logicreasoning for the generation of new knowledge. In this paper we propose a generic architecture of a CDSS based on semantic technologies, which also considers the reutilization and enhancement of former CDSS in an organization. Particularly, an implementation of the proposed architecture is also presented, aiming to support the early diagnosis of AD.

MALP (i.e., the so-called Multi-Adjoint logicprogramming approach) can be seen as a promising fuzzy extension of the popular, pure logic language Prolog, including too a wide repertoire of constructs based on fuzzy logic in order to support uncertainty and approximated reasoning in a natural way. Moreover, the Fuzzy logicprogramming Environment for Research, FLOPER in brief, that we have implemented in our research group, is intended to assists the development of real-world applications written with MALP syntax. Among other capabilities, the system is able to safely translate fuzzy code into Prolog clauses which can be directly executed inside any standard Prolog interpreter in a completely transparent way for the final user. In this fuzzy setting, it is mandatory the use of lattices modeling truth degrees beyond {true;false}. As described in this paper, FLOPER is able to successfully deal (in a very easy way) with sophisticated lattices modeling truth degrees in the real interval [0, 1], also documenting -via declarative traces-the proof procedures followed when solving queries, without extra computational cost.
