3 Course (Part 1) Formula: Web Personalization + Web Mining + + Semantic Web + Intelligent Agents = = Intelligent Web Applications - Why ? - To be able to intelligently utilise huge, rich and shared web resources and services taking into account heterogeneity of sources, user preferences and mobility. - What included ? - Introduction to Web content management. Web content personalization. Filtering Web content. Data and Web mining methods. Multidatabase mining. Metamodels for knowledge management. E-services and their management in wired and wireless Internet. Intelligent e-commerce applications and mobility of users. Information integration of heterogeneous resources.

4 Practical Information §9 Lectures (2 x 45 minutes each, in English) during period 28 October - 15 November according to the schedule; §Course slides: available online plus hardcopies; §Practical Assignment (make PowerPoint presentation based on a research paper and send electronically to the lecturer until 10 December); §Exam - there will be no exam. Evaluation mark for this part of the course will be given based on the Practical Assignment

5 Introduction: Semantic Web - new Possibilities for Intelligent web Applications

6 Motivation for Semantic Web

7 Semantic Web Content: New “Users” applications agents

8 Some Professions around Semantic Web Content Agents Annotations Ontologies Software engineers Ontology engineers Web designers Content creators Logic, Proof and Trust AI Professionals Mobile Computing Professionals

10 What else Can be Annotated for Semantic Web ? Web resources / services / DBs / etc. Shared ontology Web users (profiles, preferences) Web access devices Web agents / applications External world resources

11 Word-Wide Correlated Activities Semantic Web Grid Computing Web Services Agentcities Agentcities is a global, collaborative effort to construct an open network of on-line systems hosting diverse agent based services. WWW is more and more used for application to application communication. The programmatic interfaces made available are referred to as Web services. The goal of the Web Services Activity is to develop a set of technologies in order to bring Web services to their full potential FIPA FIPA is a non-profit organisation aimed at producing standards for the interoperation of heterogeneous software agents. Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation Wide-area distributed computing, or "grid” technologies, provide the foundation to a number of large-scale efforts utilizing the global Internet to build distributed computing and communications infrastructures.

33 Semantic Metanetwork for Metadata Management Semantic Metanetwork is considered formally as the set of semantic networks, which are put on each other in such a way that links of every previous semantic network are in the same time nodes of the next network. In a Semantic Metanetwork every higher level controls semantic structure of the lower level. Terziyan V., Puuronen S., Reasoning with Multilevel Contexts in Semantic Metanetworks, In: P. Bonzon, M. Cavalcanti, R. Nossun (Eds.), Formal Aspects in Context, Kluwer Academic Publishers, 2000, pp

34 Petri Metanetwork for Management Dynamics A metapetrinet is able not only to change the marking of a petrinet but also to reconfigure dynamically its structure Each level of the new structure is an ordinary petrinet of some traditional type. A basic level petrinet simulates the process of some application. The second level, i.e. the metapetrinet, is used to simulate and help controlling the configuration change at the basic level.
