Living Web: Making its Diversity a true asset

Chairs: Claudia Niederee and Peter Fankhauser.

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.

Web-based Multimedia Search and Retrieval

Chairs: Pere Obrador and Xavier Anguera.

Abstract. 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.

The Emergence of Web Science

Chair:  Nigel Shadbolt.

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.  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 aim of this panel is to bring this debate to the heart of the WWW community at WWW2009 in Madrid.

Web Search APIs: The Next Generation

Chair: Soumen Chakrabarti.

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.

14:30-16:00  Multilingual Web Sites

Chair: Manuel Tomas Carrasco Benitez

 Multilingual Web Sites (MWS) refers to sites with multilingual parallel texts; e.g., Europa, the portal of the European Union. MWS are of great practical relevance: the call for proposals for Multilingual Web has a budget of 14 millions euros.

There is an urgent need to address the standardization of MWS:
* Users should expect similar behaviour from different MWS.
* Webmasters should be capable of creating high quality low cost MWS.

11:30- 13:00 The role of the Telco in the new Web: is possible to create a win-win relationship?

Chair: Luis Angel Galindo.

Abstract. Main issues to cover include):
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 these services?
- Is increasing the number of technololgy disabled 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?

14:30- 16:00  Emerging technologies for combining web accessible interfaces with the development
of new interoperable ICT devices

Chair: Jose Angel Martínez-Usero. (ONCE Foundation – Technosite)

Abstract. The objective of this panel is to discuss which kind of emerging technologies can be combined with the development of web interfaces to foster accessible and interoperable interaction with a huge amount of devices, that at present are not accessible (such as ATMs, smart houses applications, public kiosks, etc.).
