Extensions for Integrated Queries on Heterogeneous Semantic Web Resources

This paper proposes extensions on SPARQL, to help RDF users inquire the TM resources.

Semantic Web query languages are designed to carry out the machine understandability of the Semantic Web. However, most popular Semantic Web query languages are separately designed for two incompatible Semantic Web frameworks, the Resource Description Framework (RDF) and Topic Maps™. Due to the absence of cross-framework query support, the interoperations between RDF and TM resources cannot be achieved seamlessly. In this paper, we propose extensions on a popular RDF query language, SPARQL, to help RDF users inquire the TM resources.With the SPARQL-X extensions, TM resources can be interoperated in a usual RDF-like triple format. Furthermore, the challenges of querying resources from different frameworks and the corresponding design issues are discussed. Some use cases of using SPARQL-X to query XML Topic Maps (XTM) resources are also presented in comparison with the use cases of Topic Maps Query Language (TMQL).

As a former information scientist, I am fascinated since 1999 by the capabilities for building Topic Maps-based knowledge systems having the potential to augment human mind. One can model arbitrary knowledge organization systems, deal with semantic heterogeneity, collocate all facts about one subject in one logical place, and with TMQL have semantic retrieval on federated semantic networks. Therefore I expect bright prospects for business concepts building on the exchange of such knowledge snippets via semantic knowledge services.
