Research team on Data & Web Mining


The Data & Web Mining group was founded in 1998. Since then there is a continuous line of research in the areas of databases and data mining. More specifically in unsupervised learning (clustering algorithms and validity measures), advanced data management and indexing (P2P systems, distributed indexing, distributed dimensionality reduction), text mining (word disambiguation for classification) and ranking algorithms (extensions to PageRank). More recently we are working in graph mining (degeneracy based community detection and evaluation), text mining and retrieval for web advertising/marketing and recommendations.

We have introduced “Data Mining” and “Machine Learning” as taught subjects in the Greek University system syllabi. Our research group has hosted ten competed Ph.D. theses and hosts three more underway. See details

Our members have published chapters in books and encyclopedias, two international books and more than a hundred twenty (120) papers in international refereed journals and conferences. Also we have coauthored three patents and attracted significant R&D funding including national and international research & development projects. Members of our team have has received the ERCIM and Marie Curie EU fellowships.

Our group has co-organized the ECML PKDD 2011 conference in Athens. Members of the group participate in the editorial board of the Intelligent Data Analysis Journal and served as guest editors for special issues of the “Machine Learning” and “Data Mining & Knowledge Discovery” journals. Also co-chaired the PC committee of ECML/PKDD 2011 conference, served the Data Mining Track chair of the IEEE - ICDE 2011 conference and has participated as a conference committee member for more than forty international conferences, in the areas: Data Bases, Data Mining/Machine learning and the Web.

We have a long experience in real-world industrial level software projects in the area of Data Mining Text Mining and Web Service/commerce. The director of the group has been invited and participated in three Google faculty EMEA summits in Zurich and London, in 2008, 2011 and 2012.
