After have analysed the qualities of the web services and the insufficiency in the existing expert systems, This paper designed an assembling unit fault diagnosis expert system of a power station based on the web services architecture, and studied knowledge database management and inference mechanism in the diagnose system in detail.
The current situation and problems of knowledge service and its supporting platform are discussed. In order to make product more competitive, a new framework of the knowledge service platform for modern design under distributed resource environment from a perspective of whole lifecycle of the products is proposed by the application of knowledge flow theory and knowledge service in this paper. This...
Web surfing has become an important activity for many consumers. We propose a web recommender that models user behavior by constructing a know ledge base using temporal web access patterns as input. We apply fuzzy logic to represent real-life temp oral concepts and requested resources of periodic pattern-based web access activities. Th e fuzzy representation is used to construct a know ledge base...
The paper based on digital city management platform, built emergency evacuation management model. First, gave the framework of digital city management platform, and then, describes the main steps of the design of digital city management platform, final, gave the emergency evacuation model based on Digital City management platform. The model based on knowledge base of emergency contingency plans, for...
This study converts the professional knowledge in WLAN problem diagnosis to the rules in the knowledge base and turns the inference engine, explanation subsystem and knowledge base of the entire expert system into service components through web services. In this manner, external systems can transmit diagnosis requests via HTTP to the WLAN problem diagnosis expert system and obtain results from it.
This paper presents a new approach for automatic Web service composition based on the formalism of Fluent Calculus using semantic Web service descriptions. In our approach, the Web service composition process is viewed as an AI planning problem in the Fluent Calculus formalism. To semantically describe Web services, we have used a Web service domain ontology which is then translated into a Fluent...
Sem@ntica is a system for extracting the information contained in collections of documents into a knowledge base. It combines high quality conventional named entity analysis with an ontology class labeling capability for open class words. The ontology comprises an upper ontology and one or more domain ontologies. The system has tools for rapidly designing the ontology and mapping segments of Word...
In this paper, the focus is on how context information can be efficiently modeled with an ontology. This ontology can than be used by reasoning algorithms which are based on this context information. This is illustrated with a use case which studies the evolution from a place oriented to a person oriented nurse call system. An ontology was designed which holds the necessary context information. A...
Advances in information technology change the way e-negotiations, which constitute an important aspect of worldwide e-trading, can be structured and represented. In this paper an e-negotiation framework for building complex negotiation systems with emphasis on their automation is presented. A novel approach for dynamically adapted e-negotiations, that exploits ontologies, semantic Web services, software...
Traditional RBAC model describes a static access control policy. As the development of network application, such as Web services, access control faces many new challenges, one of which is that access control policies need to protect not only static resources but also dynamic ones that are encapsulated in a service. In order to capture the flexibility of application, we specify a fine-grained control...
We apply our work on Web service discovery with initially incomplete information to the problem of service composition. Rich semantic descriptions of Goals and Web services allow the unambiguous specification of constraints on what services are required and offered respectively. However, the data provided in service descriptions may be incomplete. We describe how missing instance data may be fetched...
In contrast to recommending new books and to enhance utilization of one's own books, we 1) propose to build a knowledge base (KB) by collecting book information using Web services, 2) develop a book utilization system (BUS) that enables users to edit additional book information by using an XML database, 3) use a book search using Web service. We also create an infrastructure for sharing existing books...
Service oriented architecture (SOA) is a flexible software design paradigm for enterprises. The workflows of a company are implemented as services which can be arranged, updated and managed at runtime without interfering with ongoing business. Service management aims at providing undisturbed access to services. Its efficiency strongly depends on a fast response time in the case of a failure. This...
This paper proposes the SSOA (Semantic Service-Oriented Architecture) based on formal and distributed ontologies, and the knowledge base framed by ontology and the fuzzy reasoning system oriented to agent cognition are considered to prescribe and treat the uncertainty of agent cognizing. The SSOA includes two essential components: Knowledge Base Supported by Formal Ontology and Agent-oriented Fuzzy...
Complex information resources interoperability is becoming an important issue for information resources reuse and aggregation in semantic Web services. Current registration standards are relatively weak in the description of complex logic relationship between information resources. This paper proposes complex information resources registry method based on deeply semantic interoperability. The method...
Harmonized system (HS) is a systematic directory to identify the product codes based on their categories for entry and exit inspection. The identified HS codes are used, by entry and exit authorities, to determine the applicable policies for product to be inspected. We have proposed a HS codes Web service to intelligently generate the HS codes for the product names. Besides, the service can enable...
