【 摘 要 】

Information systems of every organization (ranging from large companies to individual entities) have to handle a variety of information sources, from proprietary ones to information publicly available in web services worldwide. Grasping relevant information wherever it may be and exchanging information with all potential partners has become an essential challenge. Basically, information sharing, rather than information processing, is IT's primary goal in the 21st century. The key point is that now information has to be sharable in an open environment, where interacting peers do not necessarily have a common understanding of the world at hand, as used to be the case in traditional enterprise information systems. Lack of common background generates the need for explicit guidance in understanding the exact meaning of the data, i.e., their semantics. Data semantics is more and more context- and time-dependent, and cannot be fixed once and for all at design time. Identifying emerging relationships among previously unrelated information items (e.g., during data interchange) may dramatically increase their value. Such relationships are the basic ingredients for semantic interoperability that is viewed as an emergent phenomenon constructed incrementally, and its state at any given point in time depends on the frequency, the quality and the efficiency with which negotiations can be conducted to reach agreements on common interpretations within the context of a given task. This type of semantic interoperability is referred to as \emergent semantics" [3, 5].[First Paragraph]
