• The SIGMOD Executive Committee continues to work on the relocation of the SIGMOD/PODS 2017 conference and workshops. As the uncertainty with respect to the location may be of concern to some of the participants, we have decided to extend the WebDB deadline to February 24, to allow time for the EC to finalize arrangements and announce the new location. We expect that information on the new arrangements is forthcoming.

The Web is an ever-evolving source of information, with data and knowledge derived from the Web powering a great range of modern applications. Accompanying the huge wealth of information, Web data also introduces numerous challenges due to its size, diversity, volatility, inaccuracy, and contradictions. WebDB, first held in 1998, provides a forum for researchers, theoreticians, and practitioners to share and promote insights, ideas, and novel research directions for the management of Web data. It covers a broad range of topics, including the extraction of knowledge from the Web, the transformation, generation, dissemination, and exchange of Web data, functionality pertaining to interfaces and applications, and many others.

We aim to bring together the research efforts from both the academia and industry, and we solicit papers on a broad range of research topics, types and methodologies in computer science, such as on applications and tools, systems, user experience and interface, and theoretical foundations and/or analysis.

WebDB has taken place nineteen times already, has had a high impact, and has published and provided the forum for a substantial amount of seminal research.

The theme of this year's workshop is

Web of opinions: Truths, beliefs, and conflicts.

This theme emphasizes the unique nature of Web data, a large portion of which is contributed by human users, who naturally demonstrate diverging opinions and views, resulting in data that is often uncertain, unreliable, and conflicting. Submissions relevant to the theme are particularly encouraged, but WebDB will also publish works more generally pertaining to Web data management.
