Advanced Web Applications:
Semantic and Data Processing Issues
PhD Course at DISI - Department of Computer Science, University of Genova
According to the seminal work of T. Berners-Lee, J. Hendler and O. Lassila [1] "The Semantic Web is not a separate Web but an extension of the current one, in which information is given well-defined meaning, better enabling computers and people to work in cooperation."
The first module of the course will survey enabling technologies for the semantic web, including languages, tools and infrastructures for knowledge representation and rational agents. Indeed, while the definition reported above is still valid after almost ten years, with respect to ten years ago, enabling technologies for the semantic web are now enough established to build intelligent applications that take advantage of the semantics associated with web resources. In particular, research on intelligent software agents [2] has now reached a great degree of maturity that makes its exploitation feasible for real applications.
The second module focuses on the requirements posed by Web applications on data handling and query processing techniques. Such applications often require the analysis of strongly related, highly heterogeneous data, stored in remote and autonomous data sources, that can be either totally available at query processing time (stored data) or become available in a continuous stream (data stream). In these contexts, search efficiency is a key issue. However, classical processing techniques, according to which queries are executed exactly, both for what concerns the request and for what concerns the processing technique, which is set at the beginning of the execution, may not ensure adequate performance and quality (in terms of completeness and of accuracy) of the returned result. To overcome such problem, approximate and adaptive query processing techniques have been proposed. Adaptive techniques aim at ensuring an efficient query processing whenever a priori information, needed to statically select once at the beginning of the processing the most efficient processing technique, is not available. Approximation, by contrast, has been proposed for ensuring a higher result quality in presence of data heterogeneity and limited data knowledge.
