On these issues unified representation of urban transport information using urban transport ontology, it defines the statute and the algebraic operations of semantic fusion in ontology level in order to achieve the fusion of urban traffic information in the semantic completeness and consistency. Thus this paper takes advantage of the semantic completeness of the ontology to build urban traffic ontology...

A medical image retrieval system combined of the low-level image feature and high-level semantic is used in the paper witch includes two main parts: image preprocessing and the machine learning. In the first part, feature tree structure is presented to reduce the semantic gap and in the latter part, a novel machine learning method based on SVM is presented to optimize the Network parameters by which...
With the wide use of web services over the world, an effective and efficient search engine becomes necessary. In this paper, we analyzed the limitation of search method using traditional UDDI, and make it in IR-style and take advantage of approximate string matching. Motivated by the feature of WSDL files which define the interfaces of web services, we make operations defined in WSDL files which compose...
