Abstract. Narrative descriptions about populated places are very common in ethnographies. In old articles and books on the migration history of Taiwan aborigines, for example, narr...
We identify the complexity of (finite model) reasoning in the DL SROIQ to be N2ExpTime-complete. We also prove that (finite model) reasoning in the DL SR--a fragment of SROIQ witho...
This paper describes how to generate compositions of semantic Web services using social trust information from user ratings of the services. We present a taxonomy of features, suc...
One of the challenges raised by the construction of the semantic Web lies in the analysis and management of complex relationships (thematic, spatial and temporal) connecting severa...
