Combining knowledge and beliefs of autonomous peers in distributed settings, is a major challenge. In this paper we consider peers that combine ontologies and reason jointly with their coupled knowledge. Ontologies are within the SHIQ fragment of Description Logics. Although there are several representation frameworks for modular Description Logics, each one makes crucial assumptions concerning the subjectivity of peers' knowledge, the relation between the domains over which ontologies are interpreted, the expressivity of the constructors used for combining knowledge, and the way peers share their knowledge. However in settings where autonomous peers can evolve and extend their knowledge and beliefs independently from others, these assumptions may not hold. In this article, we motivate the need for a representation framework that allows peers to combine their knowledge in various ways, maintaining the subjectivity of their own knowledge and beliefs, and that reason collaboratively, constructing a tableau that is distributed among them, jointly. The paper presents the proposed E − SHIQ representation framework, the implementation of the E − SHIQ distributed tableau reasoner, and discusses the efficiency of this reasoner.4. This is a soft form of an agreement: a) correspondences between some units may coincide but involved units do not necessarily know it (i.e. a unit does not know the correspondences of another), b) if one of the involved units drops the correspondence, this action will not affect the symmetric correspondence of the other. Although there are means for units to reach consensus (Vouros, 2013), these are not within the scope of this paper.
