    A considerable number of business process modeling approaches are developed for end-users in recent years. The core issue of end-user oriented business process modeling is how to fill the gap between end-user friendly business process model and professional IT process model. In our previous work, a wizard based lightweight event-driven modeling method is designed for end-users to create their own ... View full abstract»

  • Quantifying Consistency between Conceptual and Executable Business Processes

    Publication Year: 2013, Page(s):9 - 16
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (455 KB) | HTML iconHTML

    Business processes have been identified as effective means to developing service-based applications. It is an important and challenging research problem to check consistency between conceptual and executable business processes. Most existing approaches analyze the consistency based on qualitative equivalence relations between business processes and only provide a "true"/"false" result. Thus, they ... View full abstract»

  • QRA: A Quality Requirements Analysis Approach for Service Systems

    Publication Year: 2013, Page(s):25 - 32
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (242 KB) | HTML iconHTML

    Although quality requirements (QRs) are considered as being of crucial importance in today's service-oriented systems, existing approaches almost exclusively deal with QRs from the service providers' perspective (namely late QRs). The motivation for this paper is to address the analysis of QRs from the service customers' perspective (namely early QRs). The work presented in this paper focuses on t... View full abstract»

    Accurate and rapid evaluation of web service performance is a key problem of Service-Oriented Architecture (SOA), where services are continuously being (re-)designed and released, and integrated within heterogeneous environments. Unfortunately, pre-deployment testing of services is not suitable to evaluate service performance at both design time and runtime. As a result, often process designers ge... View full abstract»

  • Reputation-Aware QoS Value Prediction of Web Services

    QoS value prediction of Web services is an important research issue for service recommendation, selection and composition. Collaborative Filtering (CF) is one of the most widely used methods which employs QoS values contributed by similar users to make predictions. Therefore, historical QoS values contributed by different users can have great impacts on prediction results. However, existing Web se... View full abstract»

  • A Probabilistic Approach for Web Service Discovery

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (201 KB) | HTML iconHTML

    Web service discovery is a vital problem in service computing with the increasing number of services. Existing service discovery approaches merely focus on WSDL-based keyword search, semantic matching based on domain knowledge or ontologies, or QoS-based recommendations. The keyword search omits the underlying correlations and semantic knowledge or QoS information is not always available. In this ... View full abstract»

  • A Technique of Analyzing Trust Relationships to Facilitate Scientific Service Discovery and Recommendation

    Most of the existing service discovery methods focus on finding candidate services based on functional and non-functional requirements. However, while the open science community engenders many similar scientific services, how to differentiate them remains a challenge. This paper proposes a trust model that leverages the implicit human factor to help quantify the trustworthiness of candidate servic... View full abstract»

    Faced with the increasing services and users' personalized requirements, it remains a big challenge for users to effectively and accurately discover and reuse interested services. Goal oriented requirements modeling has attracted more and more attentions in services discovery and modeling, but little work has focused on extracting intentional goals from service descriptions. In this paper, based o... View full abstract»

  • A Robust Service Recommendation Scheme

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (228 KB) | HTML iconHTML

    In service computing, the quality of service (QoS) has been used to distinguish different services. Many service recommendation schemes predict how a customer might rate the QoS of various services. Based on the predicted ratings, they recommend services to the customer. Most of these schemes do not consider the unfair rating problem. As the QoS rating of a service can determine whether the servic... View full abstract»

  • A Combinatorial Auction Model for Composite Service Selection Based on Preferences and Constraints

    We propose a novel market-based approach for dynamic composite service selection based on combinatorial auctions. The combinatorial auction model that we developed allows us to incorporate service providers' and requesters' preferences in the service selection process. From the providers' perspective, the combinatorial formulation allows them to express their preferences for offering combinations ... View full abstract»

    Web service clustering is one of a very efficient approach to discover Web services efficiently. Current clustering approaches use traditional clustering algorithms such as agglomerative as the clustering algorithm. The algorithms have not provided visualization of service clusters that gives inspiration for a specific domain from visual feedback and failed to achieve higher noise isolation. Furth...

    The as a Service paradigm reflects the fundamental idea of providing basic coherent functionality in terms of components that can be utilized on demand. These so-called services may also be interconnected in order to provide more complex functionality. Automation of this service composition process is indeed a formidable challenge. In our work, we are addressing this challenge by decomposing servi... View full abstract»

  • An Efficient Algorithm for Strategy-Proof Service Composition

    One of the most typical models of service market is a reverse auction, where service providers offer their services at a certain price and a user selects a combination of the services. In the first price auction, however, a service which is cheaper and has better quality is not necessarily selected. This causes unstable outcomes which are undesirable both for a user and service providers. A possib... View full abstract»

    Service Oriented Computing Systems can be considered as a type of complex systems consisting of a number of loosely coupled autonomous and adaptive components (i.e., service components). Service quality depends on the performance of the "service group", and many dynamic factors including the expectation of service consumers, the availability of resources, etc. Trust is an important factor for dete...
