Abstract: Information filtering systems constitute a critical component in modern information seeking applications. As the number of users grows and the information available becomes even bigger it is imperative to employ scalable and efficient representation and filtering techniques. Typically the use of XML representation entails the profile representation with the use of the XPath query language and the employment of efficient heuristic techniques for constraining the complexity of the filtering mechanism. However, most of the existing research work focuses on single-core systems, even though the multi-core processors are already widely used. In this paper we propose a parallel filtering algorithm based on the well known YFilter, which dynamically applies a work-load balancing approach to each thread to achieve the best parallelization. In addition, the proposed filtering algorithm extends YFilter to also support value-based predicates in the user profiles, thus enabling both structural and content-based XML filtering. Experimental results depict that the proposed system outperforms the previous parallel approaches to XML filtering problem. (More)
