RDF triples plays a foundational role of Semantic Web for knowledge representation. But modeling e.g.the temporary evolution, spatial situation, trust and provenance require more than just a set of triples,without any reference to a situation, a point in time, or generally a context. This paper first introduces a theory named Dimensional Ontology (DO) for representing such context-sensitive knowledge...
This paper introduces a domain-independent Semantic Web application platform named DOWL, on top of which ontology (OWL) based knowledge retrieval system can be easily set up for any domains. DOWL is an integrated domain Semantic Web solution that consists of several components. The overview of DOWL is presented first in this paper, followed by the introduction of design and realization of each component...
The Chinese government has devoted to e-government development for decades. Digital archives have been built up in almost every level of Chinese government hierarchy. The structure features of the archives in Chinese government are discussed first in this paper. Then, it proposes a practical approach for text mining of these semi-structured archives. With the help of semantic Web related technology,...
Ontology (RDF/OWL) plays a foundational role of semantic Web for knowledge representation. But nowadays there are few Chinese ontology bases available, which hinders the research and development of Chinese Semantic Web applications. This paper introduces an ontology knowledge discovery tool, named OntoLTCn, which supports semi-auto domain ontology acquisition from Chinese corpus. In brief, OntoLTCn...
