At present, more and more government departments and organizations choose to open their own data to the outside world. Open data can expand the scope of data sharing and improve the use efficiency of digital resources. However, most of the open data presents massive, decentralized and heterogeneous characteristics that greatly limit the use of open data. Also, semantic interoperability between data...
Information retrieval is the essential task for traffic information service system in intelligent transportation systems (ITS). There a lot of fuzzy traffic information derived from human factor. To achieve fuzzy semantic retrieval, this paper proposes an approach using resource description framework (RDF) and fuzzy ontology. First, we apply RDF data model to represent traffic information on the semantic...
The semantic Web is turning into a new generation Web, where Web resources will be semantically annotated based on resource description framework (RDF) and ontology to share and reuse knowledge. In order to integrate fuzzy logic in the semantic Web and to represent fuzzy knowledge, this paper utilizes fuzzy ontology and RDF to represent formally the fuzzy linguistic variables, the basic of fuzzy knowledge...
Ontology-based semantic information retrieval is a hotspot of current research. In order to achieve fuzzy semantic retrieval for scientific research information in WWW, this paper applies a fuzzy ontology framework to information retrieval system for university scientific research management. The framework includes three parts: concepts, properties of concepts and values of properties, in which property's...
Ontology-based semantic retrieval is a hotspot of current research. In order to achieve fuzzy semantic retrieval, this paper applies a fuzzy ontology framework to information retrieval system in e-commerce. The framework includes three parts: concepts, properties of concepts and values of properties, in which propertypsilas value can be linguistic values of fuzzy concepts. The semantic query expansion...
Ontology is adopted as a standard for knowledge representation on the semantic Web, and resource description framework (RDF) is used to add structure and meaning to Web applications. In order to incorporate fuzzy systems into the Semantic Web, this paper utilizes fuzzy ontology to represent formally the fuzzy linguistic variables, considering the semantic relationships between fuzzy concepts. Then...
