We consider the Top-k Approximate Subtree Matching (TASM) problem: finding the k best matches of a small query tree, e.g., a DBLP article with 15 nodes, in a large document tree, e.g., DBLP with 26M nodes, using the canonical tree edit distance as a similarity measure between subtrees. Evaluating the tree edit distance for large XML trees is difficult: the best known algorithms have cubic runti...

Cosparse analysis model (CAM) provides a new signal processing paradigm for recovering cosparse signals with respect to given operator from the undersampled linear measurements in context of emerging theory compressed sensing (CS). The sparse recovery/cosparse recovery is key one brought up by this paradigm. In paper, we propose family pursuit algorithms problem when obey model, termed as itera...

WebAssign is a web-based system that supports written assignments in a virtual university. The system has been developed by the FernUniversität Hagen, the German distance teaching university, and successfully used by different faculties at our and other universities (cf. [1]). The development of WebAssign was partially supported by the federal government program MultiMedia (cf.: http://www.uvm-...

Malu Castellanos is a senior researcher at HP Labs where she has been working on different areas of data management since 1997; physical database design, real-time business intelligence and text analytics being her primary research areas in the last years. Earlier she was on the Faculty of the Department of Information Systems at the Polytechnic University of Catalunya in Barcelona, where she r...

The 2008 edition of the IEEE International Conference on Data Engineering has, once again, established a new record of submissions. In total, there were 615 research submissions, 47 industrial submissions, and 64 demo submissions for a total of 726. Such a constant increase in the number of submissions is a clear indication of the interest in the area and the health of the community. A communit...

HE 16th International Conference on Data Engineering (ICDE 2000) was held in San Diego, California, from 29 February through 3 March 2000. As the first major database conference of the new millenium, it marked the threshold of a new database era with a proliferation of exciting data-intensive, network-centric applications, and increasing penetration of database technology into the software infr...
