The approach of describing situations of persons in their surroundings is well known in Mobile Business. This approach is extended to a concept of human situations that holds for a wide range of Information Systems. Based on former empirical findings this contribution shows different cases where customer situations lead to information needs in virtual and real shopping processes.

The well-known Wikipedia can serve as a comprehensive knowledge repository to facilitate textual content analysis, due to its abundance, high quality and well-structuring. In this paper, we propose WikiRank - a Wikipedia-graph based ranking model, which can be used to extract key Wikipedia concepts from a document. These key concepts can be regarded as the most salient terms to represent the theme of the document. Different from other existing graph-based ranking algorithms, the concept graph used for ranking in this model is constructed by leveraging not only the co-occurrence relations within the local context of a document but also the preprocessed hyperlink-structure of Wikipedia. We have applied the proposed WikiRank model with the Support Propagation ranking algorithm to analyze the news articles, especially for enterprise news. These promising applications include Wikipedia Concept Linking and Enterprise Concept Cloud Generation.

One of the challenges in SOA is to provide an efficient and effective way to identify compatible Web service(s) and compose them into a service process that satisfies a user’s functional and non-functional needs. Quality of Service (QoS), like response time or throughput, might need to be optimized for the selected service process. This paper describes a system architecture and strategies Web services composition with QoS optimization. The strategies include a uniform cost backward search for optimizing response time and an improved greedy search for optimizing throughput.

Using SOA, service processes can be composed statically or dynamically using services provided by different service providers. Some services may become faulty at runtime and cause the service process to violate the end-to-end quality of service (QoS) constraint. We propose an efficient approach for replacing faulty services to ensure that the reconfigured service process still meets the original end-to-end QoS constraint. We use an iterative algorithm to identify reconfiguration regions that have a small number of services, some faulty and some healthy, in order to have more service selection options. By reconfiguring services in these selected regions rather than the whole service process, the computational complexity is significantly reduced. Simulation study has shown that our approach is efficient as most service processes can be repaired by replacing only a small number of services.

The concept of business integration as the combination of business process management and enterprise applica-tion integration may seem old hat and already well un-derstood. In practice, however, many project managers struggle with the complexity and interdisciplinarity of business integration. Specialized management frame-works are scarce in this field but are crucial to the suc-cess of projects. This paper proposes such a management framework, which has its roots in the St. Gall Manage-ment Model and is strongly influenced by empirical data from existing projects. It defines design objects in two dimensions, which depict the crucial success factors for business integration projects.

With the growing acceptance of service-oriented computing, an emerging area of research is the investigation of technologies that will enable the discovery and composition of web services. The Web Services Challenge (WSC) is a forum where academic and industry researchers can share experiences of developing tools that automate the integration of web services. In the fifth year (i.e. WSC-09) of the Web Services Challenge, software platforms will address several new composition challenges. Requests and results will be transmitted within SOAP messages. Semantics will be represented as ontologies written in OWL, services will be represented in WSDL, and service orchestrations will be represented in WSBPEL. In addition, non-functional properties (Quality of Service) of a service will be represented using WSLA format.

Over the last decade, recommendation systems (RS) have matured into a valuable approach for assisting online customers in navigating through large product or information spaces. The associated research has described and evaluated a variety of different techniques for proposing items of interest to customers. However, each of these techniques also suffers from several shortcomings. Therefore, depending on the application domain and the availability of background knowledge some algorithms and hybrid variants may be more applicable than others. However, most commercial recommendation systems are monolithic in the sense that they support only a limited subset of recommendation techniques.In this paper we therefore present ISeller, a proven industrial-strength recommendation framework for personalizing small to medium-scale e-commerce platforms. ISeller supports all basic recommendation techniques and, due to its modular architecture, hybrid variants as well. This paper focuses in particular on the generic user modeling component of ISeller as it is the prerequisite for supporting different recommendation techniques within the same application infrastructure. Furthermore, we present an application scenario showing the generic nature and wide applicability of the described user modeling component in the domain of map-based recommendations.

In this paper, we describe the design of our architecture for Continuous, Heterogeneous Analysis Over Streams, aka CHAOS that combines stream processing, approximation techniques, mining, complex event processing and visualization. CHAOS, with the novel concept of Computational Stream Analysis Cube, provides an effective, scalable platform for near real time processing of business and enterprise streams. We describe our approach with a real data center temperature analysis application.

The current industry-driven trend of providing flexible e-services lays the ground for the new research area ``service value networks'' (SVNs). We observe a rising number of industry-oriented publications provided by research departments of large companies such as IBM or SAP as well as the fact that more and more IS conferences offer special tracks on that issue. However, when it comes to formalizing and economically analyzing such SVNs that offer joint complex services to service customers, scientific approaches are in their infancy. We intend to fill this research gap by providing a clear understanding of service value networks by defining their characteristics, their structure, and their components. Mapping these aspects into a formalized model, we intend to establish a reference point for future work in the area of service value networks.

The European Commius Project aims at enabling Small and Medium Enterprises (SMEs) to collaborate easily on the level of system, semantic and process interoperability by just the use of e-mail communication. This will be achieved by enrichment of incoming e-mails, depending on their contents (semantic interoperability), with additional information. Furthermore, recommendations of expedient further steps will be provided to process the e-mail (process interoperability). This demo-paper will give a short overview of a prototype developed in the course of the Commius Project.
