The growing importance of the World Wide Web as a means to manage and publish both data and functionality has lead to new and interesting research questions in the field of databases, on already existing subjects and on completely new ones. This workshop aims at bringing together database researchers, from both the theoretical and practical side, to discuss whether the right subjects on Web data management are being researched, and whether there are new and interesting areas that have not been sufficiently addressed yet.

Therefore, we invite papers that contain theoretical results that could open up new research areas in Web data management, as well as application-oriented papers that present ideas and applications that raise new and interesting research questions.

List of Topics

Suggested, but not exclusive, topics of interest for submissions include:

Important dates:

Paper submission: Fri, Nov 3, 2006
Notification of acceptance: Thu, Nov 30, 2006
Camera-ready copy due: Thu, Dec 21, 2006
Workshop: Sat, Jan 13, 2007

Submission guidelines:

Paper submissions must be in electronic form using Portable Document Format (.pdf). Papers should be formatted according to the Springer LaTeX2e style llncs for Lecture Notes in Computer Science, which is available at http://www.springer.de/comp/lncs/authors.html. The length should not exceed 15 pages. Papers longer than 15 pages risk rejection without consideration of their merits.

The submissions will be judged for scientific quality and relevance. At least one author of each accepted paper must attend the workshop to present the work. There will be only informal proceedings, so work and results presented at this workshop may be republished elsewhere. Submissions can be sent to the e-mail address erow07@gmail.com.

Invited speakers:

There will be three invited talks at the workshop:

  1. Speaker: Bertram Ludaescher, Department of Computer Science & Genome Center, UC Davis, and San Diego Supercomputer Center, UCSD, USA

    Title: Scientific Workflows: Research Opportunities for the Practically-Oriented Theoretician

    Abstract: In recent years, 'scientific workflow' is emerging as an area of increasing research and development activity. Reasons include the growing needs in many domain science communities to better support scientific data management and analysis, thus shifting the scientists' energy away from many low-level "plumbing activities", and towards focusing on doing more of the science. While there are now many activities in scientific workflows, there are few if any theoretical foundations of the area. What is a natural underlying model for scientific workflows? What formalisms can incorporate (i) high-level workflow design issues, combining a data-oriented with a process-oriented and "science-oriented" view, and (ii) lower-level optimization issues, e.g. to exploit task-, pipeline-, and data-parallelism? There is some hope that a synthesis from a number of research areas, including databases, functional programming, and software engineering can advance the state of the art in scientific workflows. The talk will highlight some of the existing challenges and point out research opportunities for the "practically-oriented theoretician".

  2. Speaker: Ricardo Baeza-Yates, Yahoo! Research Barcelona

    Title: Web Query Mining

    Abstract: User queries in search engines and Websites give valuable information on the interests of people. In addition, clicks after queries relate those interests to actual content. Even queries without answers imply important missing synonyms or content. In this talk we show several examples on how to use this information to improve the performance of search engines, to recommend better queries, and to improve the information scent of the content of a Website.

  3. Speaker: Madhusudan Parthasarathy, Department of Computer Science, University of Illinois at Urbana-Champaign, USA

    Title: Visibly Pushdown Automata for XML

    Abstract: (to be announced)
