Living Web: Making its Diversity a true asset

Abstract. The large diversity (with respect to cultural background, school of thought, intention, opinion etc. ) underlying the content creation process  of the Web contributes a lot to the wealth and value of the Web. On the other hand, the wide variety of opinions and biased content found on the Web makes it difficult to get a balanced view on a given subject, given that many people only consider the ten search results provided as the first page of results by a typical search engine.  This panel will controversially discuss the risk of biasing through the Web as well as the potentials that are inherent in diversity and that today are only marginally exploited.

The role of the Telco in the new Web: is possible to create a win-win relationship?

Abstract. Main issues to cover are (but not only):
Can operators offer services more than the connectivity?
Net neutrality and the separation of network and services
New paradigms for competition: iPhone, flat rate in mobiles, open source, open assets to third parties
Is possible a new ecosystem (as I pursuit in the WIMS 2.0 initiative) more fair for all the actors?
User 2.0: user demands customized services. Are big players ready to provide this services?
Is increasing the number of technololgy disable people?
Are there ways in which operators need to behave more like wireline ISPs, and ways in which wireline needs to concentrate on the role of clearinghouse rather than aggregator?


Regulator (EC): Mr. Christophe FORAX - Member of the Mrs. Reding's Cabinet
Operator (Telefonica): Mr. Luis Jorge Romero - Division Director of Innovation and Standards
Internet/ISP (Google). Mss Olga SanJacinto - Division Director of Local Businesses
Vendor (HP). Miguel Carreño - Corporate Head of New Applications and Businesses
Visionaries (Red Herring) - Mr. Farley Duwall Managing Director EMEA

The Emergence of Web Science

Abstract. Since the term was coined in 2005, Web Science has provided a rallying call for researchers who are interested in the social and organisational behaviour engendered by the Web as about the underpinning technology. Web Science is inherently inter-disciplinary.  Web Science research aims to provide the means to better model the Web’s structure, describe the principles that have fuelled its phenomenal growth, and discover how online human interactions are driven by and can change social conventions. Research is needed to reveal the principles that will ensure that the network continues to grow productively. Research is required to implement principles that can settle complex issues such as privacy protection and intellectual property rights. Of course, we cannot predict what this nascent discipline might reveal. But Web science has already generated powerful insights, how the Web is structured, how resilient it is, how ideas travel through the tens of millions of blogs, how we might include information in Web content so that its accuracy and origin is more transparent. At the micro scale, the Web is an infrastructure of artificial languages and protocols; it is a piece of engineering. However, it is fundamentally about the interaction of human beings creating, linking and consuming information. It is this interaction that we also need to research and understand. It is this interaction that generates the Web's behavior as emergent properties at the macro scale. These macro properties are often surprising and require analytic methods to understand them. The Web’s use is part of a wider system of human interaction – the Web has had profound effects on society, with each emerging wave creating both new challenges and new opportunities available to wider sectors of the population than ever before.

The Web Science Research Initiative (WSRI) was launched in November 2006 by Tim Berners-Lee, Wendy Hall, Nigel Shadbolt and Daniel Weitzner. At WWW2007 in Banff, WSRI sponsored a reception to present the ideas behind Web Science to the WWW community. At WWW2008, WSRI sponsored a workshop entitled “Understanding Web Evolution: A Prerequisite for Web Science” chaired by Dave De Roure. It attracted a lot of excellent papers – see http://webscience.org/events/www2008/ - and was one of the largest workshops at the conference. In March 2009, WSRI is running its first Web Science conference in Athens, WebSci’09 – see www.websci09.org - with the aim of bringing computer scientists and social scientists together to discuss this important topic.
The aim of this panel is to bring this debate to the heart of the WWW community at WWW2009 in Madrid.
Tim Berners-Lee is confirmed as a panellist. Other invited panellists are:

Manuel Castells, Open University of Catalonia
Jonathan Zittrain, Harvard
Ricardo Baeza-Yates, Yahoo Europe
Lorrie Cranor, CMU

As the Web approaches its third decade a debate about the relevance of Web Science as a research discipline to the WWW community is an important and timely debate to have at WWW2009

Web 20th Anniversary panel

Abstract. As WWW2009 coincides with the 20th Anniversary of the Web conference organisers would like to include this panel to commemorate it. The initial idea is to provide a rich overview of the past 20 years and as well as forecast into the future.

Wendy Hall has confirmed his participation as chair of the panel.

Tim Berners Lee and Robet Caillou have already confirmed participation.

Web Search APIs: The Next Generation

Abstract. Web search APIs are provided by a handful of large Web search companies and used by a large number of developers.  Yet, downstream applications today have to depend not only on an adversarial corpus with uncertain boundaries, but also on a best-effort, black-box search system without any formal guarantees.  The provocative proposition here is that unless search APIs evolve to provide more expressive semistructured query languages involving entity and relation types, and more precise control over matching, ranking, sampling and aggregation, search consumers will remain restricted to relatively simplistic downstream processing, such as mashups that join search results with other services like maps and yellow pages.  In this panel we will urge the two sides to the search contract to discuss what features they want in the next generation of search APIs, whether the technology exists to provide these features, and whether the providers should move to provide these features.

Web-based Multimedia Search and Retrieval

Abstract. Multimedia search and retrieval research has gone a long way from its beginnings. The research community has proposed several very good algorithms for search and retrieval of both images and video, which take advantage of content analysis, text associated with that content (i.e., user generated tags, web page text, etc.) and associated camera metadata. Also, the last few years have seen the appearance of web sites that allow for image search (e.g. flickr.com), video search (e.g. youtube.com) and audio search (e.g. http://www.freesound.org), and are being used by millions of users. In most cases, these commercial search algorithms use the text and tags associated with the media, but not the content analysis generated features, due to its disconnection from the end users’ language terminology. Also the user feedback is rarely incorporated in the search process, reducing the personalization of the search results. Future commercial multimedia search and retrieval systems will have to bridge the semantic gap between low level features and the user’s language so that these features can be incorporated in the search process, which should be customizable. In order to accomplish this, a standardized way of measuring user satisfaction will have to be implemented in the research community.
