In a previous paper, a tableau calculus has been presented, which constitute a decision procedure for hybrid logic with the converse and global modalities and a restricted use of the binder. This work extends such a calculus to multi-modal logic with transitive relations and relation inclusion assertions. The separate addition of either transitive relations or relation hierarchies to the consid...
In thesauri, conceptual structures or semantic networks, relationships are too often vague. For instance, in terminology, the relationships between concepts are often reduced to the distinction established by standard (ISO 704, 1987) and (ISO 1087, 1990) between hierarchical relationships (genus-species relationships and part/whole relationships) and non-hierarchical relationships (“time, space...
We are interested in black-box conformance testing of realtime systems. Our framework is based on the model of timed automata with inputs and outputs (TAIO). We use a timed conformance relation called tioco which is the extension of the untimed relation ioco. We show that considering only lazy-input TAIO is enough for describing all possible non-blocking specifications. We compare between tioco...
Horizontal decomposition is the process of splitting a relation into sub-relations, called fragments, each containing a subset of the rows of the original relation. In this paper, we consider horizontal decomposition in a setting where some of the attributes in the database schema are interpreted over a specific domain, on which a set of special predicates and functions is defined. We study the...
It is doubtless that intuitionistic fuzzy set (IFS) theory plays an increasingly important role in solving the problems under uncertain situation. As one of the most critical members in the theory, distance measure is widely used in many aspects. Nevertheless, it is a pity that part of the existing distance measures has some drawbacks in practical significance and accuracy. To make up for their...
