Erich J. Neuhold is currently Honorary (Adjunct) Professor for Computer Science at the University of Vienna and associated with the Fakultaet fuer Informatik. Here he is involved with structured and unstructured multimedia Databases and Web-Information Systems and questions of Semantic enrichment for effective Information Interoperability and Mining. He is also investigating issues of interoper...

Advances in wireless sensors, RFID technology, and mobile devices have enabled the development of information systems that monitor and react to events in the real world. When deployed on a large (e.g., national) scale, these systems assume a high fan-in architecture, in which vast numbers of events measured at the edges of the network are continually refined, summarized, augmented, and aggregat...

TCDE, I would also like to thank Erich Neuhold for his leadership over the last four years. The activities of the TCDE are led by an Executive Committee whose members are selected by the chair. I am pleased to announce that the Executive Committee for 2007-2008 consists of Karl Aberer (Switzerland), Masaru Kitsuregawa (Japan), Per-Åke (Paul) Larson, chair, (USA), Sam Lightstone (Canada), David ...

We present a new sketch for summarizing network data. The sketch has the following properties which make it useful in communication-efficient aggregation in distributed streaming scenarios, such as sensor networks: the sketch is duplicate insensitive, i.e., reinsertions of the same data will not affect the sketch and hence the estimates of aggregates. Unlike previous duplicate-insensitive sketc...

Because of the distance between the dispersed development locations, Global Software development (GSD) is confronted with challenges regarding communication, coordination and control of the development work. At the same time, agile software development is strongly built upon communication between engineers and has proven its benefits, although, mostly on one single site. As such, it might be ad...

Motivated by the increasing availability of vehicle trajectory data, we propose learn-to-route, a comprehensive trajectory-based routing solution. Specifically, we first construct a graph-like structure from trajectories as the routing infrastructure. Second, we enable trajectory-based routing given an arbitrary (source, destination) pair. In the first step, given a road network and a collectio...

multiple traveling salesman problem (mtsp) is one of the most popular operation research problem and is known as combinatorial optimization problems. mtsp is an extension version of the famous and widely used problem named traveling salesman problem (tsp). because of its benefices in various domains, many researchers have tried to solve that, and many methods have proposed so far. mtsp is a np-...

1 This paper has appeared in The 22 International Conference on Data Engineering (ICDE) Atlanta, Georgia 2006. ABSTRACT Peer-to-peer databases are becoming prevalent on the Internet for distribution and sharing of documents, applications, and other digital media. The problem of answering large scale, ad-hoc analysis queries – e.g., aggregation queries – on these databases poses unique challenge...

Several recent events have heatedly discussed the applicability of database technology to the Internet and the World-Wide Web (e.g., Dewitt’s VLDB-95 talk, a 1996 DIMACS Web/DB workshop, ICDE-98 panel). One of the areas that has emerged from these discussions as a candidate for impact of the database community is that of of Web site construction and management. In parallel, several research pro...

It is time to hand over the chairmanship of the IEEE-CS Technical Committee on Data Engineering. I took over from Erich Neuhold in 2007. I have had the pleasure of working with an oustanding TCDE Executive Committee comprised of Calton Pu, Thomas Risse, Erich Neuhold, Guy Lohman, Karl Aberer, Masaru Kitsuregawa, David Lomet and Yannis Ioannides. TCDE has continued to sponsor several conferences...
