Data Semantics on the Information Superhighwayway. We begin by describing a system that treats character string data as genuine text in a natural language, and adds the level of semantic understanding provided by thematic analysis. Extensions of conventional database type systems and query paradigms are needed for handling text and document and

Value-added Mediation in Large-Scale Information Systemseral companies in the same line of business, predicting the weather, and checking on transportation resources. We assign such sharable services to an active middleware layer, interposed between clients and servers. We define domain-specific mediator modules to populate this layer..Such mediating ser

Information Visualization: The Need for a Data Base Approachon. We can no longer ask users to work with low-level graphics tools to create information presentations. Rather, we want users to be able to ask, at a high level, for visualizations which will help with a particular task, or will emphasize a certain trend. In order to automatically create such pres

The Context Interchange Network Prototypegration of contextually (i.e., semantically) heterogeneous data. The system uses explicit context knowledge and a context mediator to automatically detect conflicts and resolve them through context conversion. The network also allows for context explication; making it possible for a receiver of data

Extending a Multidatabase Manipulation Language to Resolve Schema and Data Conflictse requirements to preserve their local autonomy. Semantic heterogeneity is concerned with the differences in the meaning and interpretation of similar data objects across the different systems. In loosely coupled database federations, static schema integration may be not feasible and heterogeneity c

To support this rule-based active mechanisms, it is desirable that rules can be taken into account on the conceptual level. Another important reason for focusing on rules is th
