On Intuitionistic Fuzzy Representing Temporal and Factual Uncertainty

摘要

The challenging task of an information system is the representation and management of indicative information from multiple sources describing the state of some enterprise. Most snapshot database models represent enterprises that are crisp with no imprecise data, where all relationships are fixed, and all attributes are atomic valued. In temporal databases, approaches are dealing mainly with precise absolute times. A few approaches deal with imprecise absolute times or with infinite absolute times. No consideration has been given to imprecise infinite absolute times. Many algebraic models are dealing with temporal or value imperfection, with no description of semantics of uncertain information. This paper is suggesting an application independent conceptual framework that describes the semantics of temporal and incomplete information, and shows how this can be translated to database representation. An intuitionistic fuzzy interpretation of the discussed objects is suggested.
