With growing product portfolios of eCommerce companies it gets increasingly challenging for customers to find the products they like best. Current recommendation approaches primarily rely on customer-product affinities derived from explicit ratings or historical purchases. In this paper, we introduce SARI OpenRec, an extendible framework combining the capabilities of complex event processing and recommendation...
In a Service-Oriented Architecture (SOA) based on Web Service technology the services typically communicate with each other by passing data values directly from one service to another. In the case the services are orchestrated by workflows the services receive their input values from the workflow engine and return their calculated results back to the engine by value. In this paper we show several...
The volumes of data in information systems are growing drastically. The systems become increasingly complex in trying to handle heterogeneity of ubiquitous components, standards, data formats, etc. According to the vision of Autonomic Computing, the complexity can be handled by introducing self-manageable components able to "run themselves." Agent Technology fits this vision, whereas interoperability...
