The process of semantic web service composition arranges several web services into one composite service to realize complex workflows with an exploitation of semantics. This paper proposes a framework to automatic semantic web service composition. Its advantage is that a huge amount of computation is performed during preprocessing and the composition approach is designed to exploit the parallel execution of processes which is nowadays supported in multiprocessor platforms. The framework is built to suit the WS Challenge competition requirements.

Content providers compete for the user's attention on information services offered. The placement of content within a Web site is an important factor, influencing behavior of and choices made by users.The Gugubarra project aims at understanding the interests of registered users, by evaluating their behavior and actions performed while visiting the site. For this purpose, we have introduced the concept of ``zones'', which allows segmentation of a Web page, thereby enabling us to consider the placement of information and the possible actions taken by users within these zones. This paper describes the evaluation of the use of zones and their applicability in different scenarios. Several tests were performed using one of our tools to create zones on different Web sites. The main focus is to evaluate aspects of the zoning concept and to test how zones are used in real life situation. The test results should show how the chosen semantics of topic weights influences the use of zones and topics.

Workflow technology promises an increase in efficiency in the execution of business processes. The technology is widely accepted, but often the high costs exceed the promised benefits. Thus, it is desirable to calculate the profitability prior to investing into workflow technology. After an investment into workflow management systems (WFMS), it has to be verified whether the expected benefits have been realized or not. In this paper we present a method that covers both, the cost-benefit-ratio calculations specially customized for WFMS and the calculation of the realized savings. The profitability analysis is based on simple measurable performance indicators that consider the tangible calculation of costs as well as the quantitative and qualitative benefits. Long time practical experience in implementing and operating workflow management supported the design of the method. The method presented in this paper has been successfully used in the IT company of a banking corporation.

Abstract—Automatic service composition has been a hottopic in both academia and industry. It begins with syntacticcomposition, and then evolves semantic description. Recently, QoS of the composition comes into researchers’ mind, which aims at meeting the need of the overall qualities like service fee, response time, throughput, etc. In this paper, a novel QoSaware approach is presented. It adopts a forward filtering algorithm to reduce the number of service candidates, along with a modified dynamic programming approach to compute optimal values. Finally, a backward search is utilized to find out the optimal composition results efficiently.

Business processes are at the core of today’s businessworld. Most of the effort put into business processes in practice is either the task of designing a new process or the task of analyzing and improving an existing process. In both cases, visualizations of the process models support the user in achieving his objectives. In this paper, we present the first prototype of our tool “BPMN-Layouter”. Our supported notation language is the business process modeling notation (BPMN). The tool was implemented to integrate several concepts that we developed and adopted for the use in BPMN modeling. The integratedapproaches comprehend the tasks of finding an automatic layout for a BPMN model, increasing the readability of given visualizations and developing further existing BPMN models in an interactive fashion. Also, a method for automatic division of complex BPMN models is provided, too.

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.

Building Information Model (BIM) encompasses building geometry, spatial relationships, geographic information, and quantities and properties of building components; however, it does not include any information related to the functions that a building might require. On the other side, Service–Oriented computing emerged as a promising technology to enable fast, efficient software development. Even though features such as standard protocols, loosely coupled components, ontology-enabled dynamic discovery and composition of SOA seems a perfect fit for the building construction domain, the potential gain of applying SOA techniques has not really been discovered. In the paper, an ontology-based service composition framework for construction domain is proposed, and BIM is extended to include function requirements and service specifications. An example is shown to demonstrate the advantages over traditional techniques also.

A business process needs to be constantly reviewedto accommodate new business requirements and regulations.To this end, it is important to manage the impact of this reviewon a process by determining which parts are affected and morecritically estimating the overall cost of this review. In thispaper we present an approach to manage the changes in aprocess. We model a process as a set of business rules that arestructured using the ECAPE formalism standing for Event,Condition, Action, Post–condition, and post-Event Thisformalism allows translating a process into a graph of rulesthat is used for two types of analysis: business processes agilityand cost of changes. This cost is based on our Rule ChangeCost Model (R2CM).

Traditional recommendation approaches do not consider the changes of user preferences according to context. As a result, these approaches consider the user’s overall preferences, although the user preferences on items varies according to his/her context. However, in our context-aware approach, we take into account not only user preferences, but also context information. Our approach can be easily adopted for content-based and collaborative filtering based recommendations. To exploit raw context information in recommendation, we abstract the raw context information to a concept level. Moreover, by aggregating the context information, we can improve the quality of recommendation. The results of several experiments show that our method is more precise than the traditional recommendation approaches.

Complex Event Processing (CEP) systems are capable of processing large amounts of events, utilizing them to monitor, steer and optimize business in real time. The lack of tracking events and maintaining the causal relationships and traceability between those events, as well as aggregating them to higher-level events, is a problem that is currently investigated by many research groups. In this paper, we present SARI-SQL, which is a domain-specific event-query language, (EQL) that is designed for business analysts to easily gain insight into business events. SARI-SQL enables the retrieval of near real-time events and can process historical events, metrics and scores for analytical purposes. We introduce the SARI-SQL syntax and show infrastructural components for the query engine. We further show examples to illustrate the query language, and propose a reference implementation for the query engine.
