In this paper we present an analysis of the development process of technology-supported didactic material. Such analysis considers didactic materials as the conjunction of contents and instructional design used to guide learning and teaching processes. And we examine why several features such as reusability, semantic interoperability and collaboration support must be ensured from the earlier st...

Research on Interoperability of geospatial information systems is becoming widespread in GI research community. We have identified three types of heterogeneity: semantic, schematic, and semantic. We argue that the current technological development is focused on resolving the syntactical problems, with little to know attention to the schematic and semantic differences, respectively. In this pape...

The assessment of semantic similarity among objects is a basic requirement for semantic interoperability. This paper presents an innovative approach to semantic similarity assessment by combining the advantages of two different strategies: feature-matching process and semantic distance calculation. The model involves a knowledge base of spatial concepts that consists of semantic relations (is-a...

The major challenge when integrating information systems in any domain such as e-Government is the challenge of Interoperability. One can distinguish between three aspects of Interoperability; technical, semantic, and organizational. The technical aspect has been widely tackled especially after the ubiquity of internet technologies. The semantic and organizational aspects deal with sharing the ...

In this paper, we describe an ontology-based collaboration model for supporting semantic interoperability in open networked systems. We characterize discovery and matchmaking semantic interoperability services for retrieving information resources semantically related to a target request, to enable a coordinated and virtualized access to distributed heterogeneous information resources.

We discuss current approaches that, for the sake of automation, provide formal treatments to the problem of semantic interoperability and integration, and we reflect upon the suitability of the Barwise-Seligman theory of information flow as a candidate for a theoretical framework that favours the analysis and implementation of semantic interoperability scenarios.
