String and tree analysis and processing

Project goals

Information society uses results of pattern matching every day and its importance keeps rising. The pattern matching is no longer limited to ordinary texts. Searching in more complex structures is required like searching in trees (XML data structures), in 2D images, or in compressed data.The proposed project aims not only to extend our research results in Stringology, but also apply our knowledge in quite new topic dealing with pattern matching in trees that we call Arborology. Our strong background inparsing seems to be very efficiently utilized in Arborology. In Stringology we would like to continue on topics like multidimensional pattern matching, searching for regularities in strings, generalized string matching, and parallel approaches to patternmatching. In Data Compression we developed algorithms for exact pattern matching in compressed data. We want to improve our results and expand to approximate pattern matching. The idea of using approximate string matching in dictionary compression methods seems to be effective so we would like to continue our research in this area.
