Abstract
In the area of ubiquitous computing, users will continuously interact with computing devices by suggesting strategies, hypothesis, by communicating some new facts from domain knowledge, explaining untypical cases in dialogs with devices, etc. Hence, compound vague concepts used by humans should be understandable, at least in an approximate sense, by these devices. We present current results on approximation of compound vague concepts which are based on rough-granular computing. In particular, we use hierarchical methods for approximation of domain ontologies of vague concepts. The developed methodology is illustrated by real-life examples related to such areas as unmanned area vehicle control, robotics, predicting of risk patterns from temporal medical and financial data, sun spot classification, bioinformatics. We also discuss an extension of the proposed approach on approximation of theories related to simplified fragments of natural language.

Andrzej Skowron is the author and co-author of over 350 scientific publications, more than 20 edited books and several special issues of international journals like Pattern Recognition Letters, Neurocomputing, Computational Intelligence, Journal of Intelligent Information Systems (Kluwer), Journal of Intelligent Systems (Wiley). His areas of expertise include soft computing methods and applications, reasoning with incomplete information, approximate reasoning, rough sets, rough mereology, granular computing, synthesis and analysis of complex objects, intelligent agents, knowledge discovery systems and advanced data mining techniques including process mining, decision support systems, adaptive and autonomous systems.
Since 1995 he is the Editor-in-Chief of Fundamenta Informaticae journal and a member of Editorial Boards of several others journals including Knowledge Discovery and Data Mining and Knowledge and Information Systems, An International Journal. He is the co-editor-in-chief of the journal LNCS Transactions on Rough Sets published by Springer.
Andrzej Skowron was the President of the International Rough Set Society from 1996 to 2000, and now he is a member of Steering Committee of IRSS. He served or is currently serving on the program committees of over 70 international conferences and workshops, as program committee member, program chair or co-chair. For example, he was the program chair of The 2005 IEEE/WIC/ACM International Conference on Intelligent Agent Technology (IAT’05) and 2005 IEEE/WIC/ACM International Conference on Web Intelligence (France, 2005), the co-program chair of the IEEE International Conference on Granular Computing (GrC 2005) (Beijing, 2005), and the co-chair of the conference Trends in Logic III: In memoriam of Andrzej Mostowski, Helena Rasiowa, and Cecylia Rauszer (Poland, 2005). He has delivered numerous invited talks at international conferences including a plenary talk at the 16-th IFIP World Computer Congress (Beijing, 2000). In 2005 he delivered keynote talks at 8th International Conference on information Sciences (JCIS 2005) (Salt Lake City, USA, 2005) and at the First International Conference of Pattern Recognition and Machine Intelligence (Kolkata, India, 2005).
Throughout his career Andrzej Skowron has won many awards for his achievements, including awards from the Ministry of Science, the Rector of Warsaw University, the Ministry of Education, Mazur’s Award of the Polish Mathematical Society, and Janiszewski’s Award of the Polish Mathematical Society. In 2003 he received the title of honorary professor from Chongqing University of Post and Telecommunication (China). In 2005 he has received the ACM Recognition of Service Award for Contributions to ACM.
In recent years he was involved in several national and international research and commercial projects related to, e.g., data mining (fraud detection, web mining), control of unmanned vehicles, medical decision support systems and approximate reasoning in distributed environments.
He was the supervisor over 20 PhD Thesis.
