With the rapid development of vehicle electronic systems, the vehicle software failure rate has also been rising over time. Providing the convenient and effective maintenance on the vehicle software has become a fundamental block constraining the progress of vehicle electronic industry. A trusted remote remediation framework for vehicle software is presented and realized to enable drivers to online upgrade version or fix bug without needing for driving the vehicles back to the factories or using the specific devices. In this framework, the trusted remediation server takes responsibility for managing and providing the patch programs and the trusted remediation client can download directly from the remediation server to upgrade programs or fix software errors, achieving the self-repair in complex vehicular networks.
Deep Web contains a significant amount of visited information, in order to be able to make full use of the information, we need to organize it according to different domain. Therefore, it is imperative that Deep Web d...

One kind of semantic Web service modeling and reasoning method based on description logic with Boolean role constructors (SROIQB) was introduced. By using DL to figure out the hyponymy relationship between concepts in domain ontology and model Web service functional semantic in ServiceProfile, and define Boolean role expressions to describe the composition process in ProcessProfile respectively. Furthermore, Boolean role expression is introduced to describe all possible composition structures of atomic services and then semantic Web service composition can be regarded as a process of consistence checking and class subsumption computing reasoning on DL knowledge base. Thus the comparison and example validation show that introduced one kind of new and reasonable semantic Web service modeling and composition method in the framework of semantic Web by using SROIQB, which with more strong expressive capability and decidable type inference.
Schema matching is important for schema integration and thus has got great attention. In this paper, we present an ontology-based algorithm to match a larger number of interface schemas, which can hand both simple and...

Currently, the research for the extraction of information in deep web is pretty active. Although many researchers already adopted ontology in the data extraction, many problems still exist. This paper proposed an ontology evolution based method for mining in the data area. Not only will this method solve the problem when the website only consists of one record, but it also can identify he meaning of data that has no labels. With the evolution of ontology, the extraction of data records is being more accurate. Experiments indicate that this method could improve the accuracy and efficiency of data extraction.

This paper proposed a complex ontology evolution based method of extracting data, and also completely designed an extraction system, which consists of four important components: Resolver, Extractor, Consolidator and the ontology construction components. The system gives priority to the construction of mini-ontology. When the user submits query keywords to the deep web query interface, the returned result will pass through the prior three components;after that, the final execution result will be returned to user in a unified form. This paper adopted an extraction method that is different from the general ontology extraction. More specifically, the ontology used in extraction here is dynamic evolution, which can adapt various data source better. Experimental results proved that this method could effectively extract the data in the query result pages.

To find an optimal elimination ordering for Bayesian networks, a multi-heuristic-based ant colony system named MHC-HS-ACS is proposed. MHC-HS-ACS uses a set of heuristics to guide the ants to search solutions. The heuristic set can evolve with the searching procedure in an adaptive way. MHC-HS-ACS also utilizes a heuristic-based local search to accelerate its convergence. computational experiments show that MHC-HS-ACS can find very high quality solutions.

According to the characteristics of the optimal elimination ordering problem in Bayesian networks, a heuristic-based genetic algorithm, a cooperative coevolutionary genetic framework and five grouping schemes are proposed. Based on these works, six cooperative coevolutionary genetic algorithms are constructed. Numerical experiments show that these algorithms are more robust than other existing swarm intelligence methods when solving the elimination ordering problem.
