Data streams are becoming an important concept and used in more and more applications. Processing of data streams needs a streaming engine. The streaming engine can start query processing once initial data is available. This capability is especially important for real-time computation and for long-relay transmission of data streams. In this work, we demonstrate a monitoring system of eBay auctions, which is based on our RDF stream engine and can analyze eBay auctions in a flexible way. Using our monitoring system, users can easily monitor the eBay auctions information of interest, analyze the behavior of buyers and sellers, predict the tendency of auctions and make more favorable decisions. Furthermore, each step during RDF stream processing can be visualized allowing a better and easier understanding of the internal processes. This paper is an extended version of [22].
