    The quantity of biomedical publications is growing at an exponential rate. With such explosive growth of the content, it is more and more difficult to locate, retrieve and manage the resulting information. This is why text mining has become a necessity. The main goal of biomedical research is to put knowledge to practical use in the form of diagnoses, prevention, and treatment. It is important to ... View full abstract»

    This paper focuses on web pages clustering as a tool for typical Web patterns searching and using. Traditional methods of cluster analysis, self-organizing map and nonnegative matrix factorization were applied. Web pages on products sale and automatically detected Web patterns were used as a testing data. The application of GD-CLS (gradient descent constrained least squares) which combines some of...

    Web service chaining forms one of the basic operation during Web service composition. To decide whether services can be chained, semantic matching between the I/O is usually evaluated. In this paper we propose an approach considering possible adaptation of output data before it is consumed as input by other service. We also define the corresponding rules based on which it is evaluated if the chain... View full abstract»

    With the advance of Semantic Web, the adoption of Semantic Web has been regarded as the most promising way to improve the recall rate and precision rate of service discovery. However, Semantic Web Service discovery (SWS) is essentially not used on a large scale in real business world due to its time consuming performance and weak support for the QoS-based discovery. In order to solve these problem... View full abstract»

    Complex service-oriented systems comprise humans and software services spanning multiple organizations. These systems are highly dynamic, because services, processes, and teams are not only diverse but they also constantly evolve. Therefore, these systems introduce a variety of challenges on how to adapt services, processes, and teams to changing situations. We contribute with our approach to addr... View full abstract»

    Improving the ontology integration seems to be an important thing for maintenance of cooperation among various directions of ontology engineering (semantic web services, social networks, etc.). While particular ontologies cover a view at one specific domain of interest, many applications require much more general approach to describe their data. On this account it approaches to a promising solutio... View full abstract»

  • Towards More Effective Support of Service Composition: Utilizing AI-planning, Semantics and User's Assistance

    Publication Year: 2009, Page(s):50 - 55

    There are various approaches to service composition - some of them mainly based on AI planning. Although they offer relatively good results, in some cases they are not sophisticated enough to solve real problems. We identified some problems with automatic composition. Our belief is that the natural way to improve these techniques is to include user into the process of composing services. The goal ... View full abstract»

    This paper presents a method to automatically construct a sequence of mediation services needed to adapt an existing service interface into a required new form. The expected use of this method is mainly in heterogeneous service-oriented environments where Web Service and other technologies have to coexist. Unlike most other works in the area of Web Service composition, we do not focus on semantics... View full abstract»

  • Reputation-Based Trust Network Modelling and Simplification in Multiagent-Based E-Commerce Systems

    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (698 KB) | HTML iconHTML

    In this paper, we present a description model of a trust network graph (TNG)-for multi-agent-based e-commerce systems, which is similar to the relationship network formed among people's transaction activities in the real-world. The method assumes that a multi-agent system in a domain constitutes a community and so the trust network is modelled by the means of a graph in the community. Several nota... View full abstract»

    In this paper, we propose a integrate framework for evaluation and selection of service composition based on distributed agent. Meanwhile, a distributed method, which is used for acquiring the user-based quality data of Web services (WSs) from the agents scattered in the network, is introduced. In the framework, the location and time factor, concerning quality of Web service composition, is consid... View full abstract»

    In this paper a method of automatic composition plan creation that relies on automatic extraction of dependencies among services is investigated. For automatic dependency extraction our approach makes use of semantic similarities between I/O parameters of services. Extracted I/O dependencies are represented using a directed graph. The approach recognizes when cyclic dependencies exist and proposes... View full abstract»

    The event calculus is a logical formalism that provides the ability for a software agent to understand sequences of events and how they can affect system states. We are interested in the application of this formalism to the Web at large through semantic Web languages which offer access to a continually growing body of interconnected knowledge bases. We describe a simplified version of the event ca... View full abstract»

    The aspect of human interaction becomes more and more relevant for service-oriented applications. On one hand, current development approaches support the composition of services but neglect the creation of user interfaces. On the other hand, task-based modeling of user interactions is well established but poorly integrated into service-oriented development. In this paper we propose an integrated m...
