Przemysław Kazienko, Ph.D., D.Sc. - Homepage

I am working as a professor in The Department of Information System being a part of The Institute of Informatics, Wroclaw University of Technology.

Research areas

• Social networks (SNs) and social network analysis (SNA).
  
  We have established Social Network Group - a research group that consists of several full time researchers, as well as some Ph.D. and M.Sc. students. Its web site is available here. The group is closely related with the Student Research Group "DaniE" - Data and Exploration.
  
  The main, recent research areas in the domain of SN include:
  • Analysis of multi-layered social networks; measures in multi-layered SNs; clustering and prediction of groups, etc.
  • Extraction of multi-layered social networks from data about common activities and mutual communication of users
  • Classification in social networks, collective classification
  • Social networks in evaluation of organizational structures, graph comparison
  • Latent knowledge acquisition based on social relationships
  • Application of social network analysis in marketing
  • Social networks on the Internet and telecommunication
  • Social networks in analysis of criminal networks
  
  You are invited to the following scientific events and special issues organized by us:
  • CSNA 2012 - International Workshop on Complex Social Network Analysis, co-located with ASONAM 2012, 26-29 August, 2012, Istanbul, Turkey
  • SNAA 2012 - The Second Workshop on Social Network Analysis in Applications, co-located with ASONAM 2012, 26-29 August, 2012, Istanbul, Turkey
  • A special issue of Journal of Universal Computer Science (JUCS), Vol. 18, Issue 4, 2012 (JCR journal, indexed by SCI, DBLP, Scopus, etc.).
  • SNAA 2011 - The First Workshop on Social Network Analysis in Applications, co-located with ASONAM 2011, July 25-27, 2011, Kaohsiung, Taiwan.
  
  You are also invited to our periodic monthly meetings - seminars (every second Tuesday) at WrUT related to social network and complex network analysis.
  
  In this area we co-operate with some companies: British Telecom, Intelligent Systems Research Centre (ISRC), Research & Engineering Center REC and Telnet. In the past also within The European Network of Excellence Nature-inspired Smart Information Systems.


• Multiple model systems and hybrid prediction (classification), multi-label classification, especially for complex structures in output (structured output prediction), e.g. sequences.
  
  Together with Edwin Lughofer and Bogdan Trawiński as well as previously with Oscar Cordón, we organize a series of special sessions and special issues of journals:
  • A Special Issue on Hybrid and Ensemble Methods in Machine Learning, Journal of Universal Computer Science (JUCS) (JCR-listed journal), 2013.
  • MMAML 2012, Special Session on Multiple Model Approach to Machine Learning, The 4th Asian Conference on Intelligent Information and Database Systems, Kaohshiung, Taiwan, March 19-21, 2012, Springer, LNAI, 2012. Envisaged postconference special issue.
  • MMAML 2011, A Special Session on Multiple Model Approach to Machine Learning, at The 3rd Asian Conference on Intelligent Information and Database Systems, Daegu, Korea, April 20-22, 2011, LNAI 6592, Springer.
  • A Special Issue on Hybrid and Ensemble Methods in Machine Learning of International Journal of Applied Mathematics and Computer Science (indexed by SCI, JCR, DBLP, Scopus, Inspec, etc.) with extended versions of the selected papers, is scheduled for 2012.
  • MMAML 2010, Special Session on Multiple Model Approach to Machine Learning, at The 2nd Asian Conference on Intelligent Information and Database Systems, Hue City, Vietnam, March 24-26, 2010, Springer, LNAI 5991, 2010.
  • A Special Issue on Hybrid and Ensemble Methods in Machine Learning, Vol. 29, No. 3, 2011 in the journal New Generation Computing (indexed by SCI, JCR, DBLP, Scopus, Inspec, etc.).
  
  
• Web-based recommender systems
  
  • Project ROSA (Remote Open Site Agents) - web recommender system - the part of the general concept of "adaptive web sites". The prototype had been accessible on this page for the certain time (it is not maintained any more).
  • The extension of ROSA was AdROSA - the system for personalized web adversiting, in which the recommended items were web advertisements (banners).
  • Take also a look at WindOwls - prototype e-commerce with windsurfing (at the moment only in Polish - sorry), in which 5 recommendation methods were integrated in the personalized and adaptive way, i.e. separately for each user. The site has been implemented by Paweł Kołodziejski.
  • The International Workshop on Recommender Agents and Adaptive Web-based Systems (RAAWS 2005). Selected, extended versions have been published in International Journal of Computer Science & Applications, Vol. 3 Issue 3, 2006.
  • The second edition of The International Workshop on Recommender Agents and Adaptive Web-based Systems (RAAWS 2006) was held in England at KES 2006, LNAI 4253, Springer Verlag. See also a special issue of the journal New Generation Computing (JCR journal).
  
  
• Data mining in information systems especially in web environment - web mining. Most recent research focuses on association rules, especially negative patterns.
• Databases for simple devices - modular databases.
• Aplications and the future of languages derivered from XML.
• Data security: electronic signature and intrusion detection systems.
• Content management systems (CMS).
• Information Retrieval in the Internet environment.
