The following topics are dealt with: enterprise computing; e-commerce privacy and security; e-service; resource management; media management; business collaboration and semantic Web service composition.
We investigate the structures of collaboration in software development groups by analyzing the data derived from the versioning system SVN (subversion) for several open source projects of different types and sizes. The goal of the work presented here is to investigate specific properties of the network topology in the collaboration groups of open source developer communities. For this purpose we developed...
Today, most approaches for inter-organizational business processes start bottom-up from the interfaces and the workflows of each partner described on the IT layer. Alternatively, one may start from the commitments and agreements between business partners to reach their complementary business goals. The latter approach is target of the UN/CEFACT Modeling Methodology (UMM), which models a global choreography...
Today, personalized services are lucrative for service providers and their customers. With their increasing pervasiveness and interconnection, however, customers show concerns about their privacy. If customers were to refuse the processing of their personal data in general, the economic potential of personalized services could not be realized. We claim that such scepticism is a direct consequence...
The exchange of inter-enterprise and intra-enterprise logistics services in the transport logistics sector has become more important. Nevertheless, only a few approaches are able to take into consideration the synergy effects between the customer orders in the case of the outsourcing process and the preferences of customers. In this article, an approach is introduced which offers a solution based...
Online retailers have associated the introduction of user-generated product reviews with increased customer sales and decreased product returns. For all of the perceived value conveyed by customer reviews, however, little effort has been directed towards leveraging user-generated content beyond a product centric focus: customers first select a product in order to read from prior users of that product...
The collaboration landscape evolves rapidly by allowing people to participate in ad-hoc and process-centric collaborations. Thus, it is important to support humans in managing highly dynamic and complex interactions. The problem currently with managing interactions is that humans are unable to specify different interaction interfaces for various collaborations, nor able to indicate their availability...
Various approaches to automate the observance of compliance requirements have recently been proposed. Since there is no all-round solution available within the foreseeable future, we propose a classification scheme for existing approaches that address different aspects of automating compliance. A layer model is used for linking laws and regulations with a company's IT system. The "policy layer"...
Valuation-aware traffic-control mechanisms for road intersections take the valuations of reduced waiting time of the individual drivers into account. They use agents to avoid any disturbance of the driver, and they feature mechanisms specifically designed for negotiating valuations. While such mechanisms do indeed increase overall driver satisfaction, they only allow one vehicle at a time to use the...
WSDL Web services are built around the request-reply framework, requiring service invocation to be bundled together with all relevant data in a single message. Inefficiency becomes evident as Web service providers begin to offer more robust services that require massive datasets (e.g., multimedia and scientific data). Under the WSDL standards, these hefty datasets must be ported to an appropriate...
We discuss an agency model for an e-market place. When a marketplace goes from brick-and-mortar to virtual, incentive issues according to asymmetric information of e-mall providers become significant because contracting for an e-mall service can be "outcome-based." We discuss the Internet firm's incentives associated with the cost of operating an e-mall and different types of contracting...
The development of mobile services becomes more challenging when context-awareness is taken into account. There are many problems in designing a successful context-aware mobile SOA. In this paper, we introduce the model of "dynamic capabilities" to study how systems can dynamically integrate, compose, and reconfigure internal and external competencies in responding to rapidly-changing environments...
Integrating service description, discovery, and invocation functionalities presents several fundamental problems in the management of web services and is a basic problem for composing Web services over a network. In this paper, we present the design of a system called "semantic service, wrapper, and invocation manager" (SSWiM) which provides these key functionalities. In particular, SSWiM...
