Soft resource allocation is an important factor of system configuration which plays a critical role in guaranteeing the performance of multi-tier web service systems. There is a tradeoff between real-time performance and resource consumption, and thus the real-time adjustment of soft resource allocation in response to dynamic workload is quite challenging. In this paper, we propose a real-time soft...
In service-oriented environments (e.g. Cloud Computing or Utility Computing), automated service discovery is crucial to enable self-organizing technical components that are able to discover and consume services autonomously. To this end, precise and robust service discovery algorithms are desirable. In this paper, we propose an approach combining both syntactic and semantic search to increase accuracy...
Automated end-to-end Service Level Management (SLM) is crucial to enable self-organising Service-Oriented Architectures (SOA). In this paper, we present an approach based on Organic Computing to enable automated SLM by using automated service level negotiation. The evaluation results in a simulated SOA environment are presented to show the applicability of our approach.
Ontology matching is critical to semantic interaction and knowledge sharing. The purpose of ontology matching is to reuse the ontologies and integrate them in different fields. It is the basement of the other semantic Web application, such as, semantic Web-based service, ontology alignment. Nowadays most ontology mapping approaches integrate multiple individual matchers to explore both linguistic...
The better way for Web services discovery is to classify the Web services into different categories when they are published in a registry. The method of intelligent clustering based classification of the Web services is mainly studied. A hybrid solution is proposed for building and populating a taxonomy structure by combining human knowledge with the techniques of artificial intelligence. The Web...
This paper has proposed a method which implements the web service dynamic composition based on an annotated ontology. The capability parameters of the registered web services are used to annotate the domain ontology, when a request comes, only the related web service according to the annotated ontology will be matched or be composed. With the method, the efficiency can be improved significantly when...
Web services have become the prominent standards for distributed application. Extending from software component, web component is a new paradigm to support service-oriented software development and reuse in web environment. Web component aims at providing support to service-oriented development by enabling automatic discovery, composition, invocation and interoperation of services. Semantic support...
WBISD is a tool that utilizes Eclipse plug-ins and other World Wide Web tools as a debugger to help Web-based interactive service developers debug the Web pages. The users of our system simply start debugging by interacting with the provided GUI environment of the tool. They can view the Web-based interactive service parameters encoded in URLs of dynamic Web pages obviously. WBISD can improve development...
Semantic Web service makes service representation and discovery more machine-understandable by adopting ontology semantics. However these representations are inadequate to descript and discover services imprecisely requested by human. Fuzzy ontology is an extension of the domain ontology. It is more suitable to describe the domain knowledge for uncertainty representation and reasoning. In this paper,...
