Content

The Web 2.0 movement has brought a new generation of usability and socio-technical change to the Web. At the same time, several so-called Web 2.0 applications had enormous success: Wikipedia, del.icio.us, Flickr, YouTube, Facebook, Twitter, Geni – to name just a few. Having differing objectives, they all have something in common: huge amounts of enthusiastic users contributing and creating a plethora of content. The high acceptance of these applications with Web users from all over the world prove that they are usable and – more importantly – provide some kind of benefit. Each of the applications has incentive structure well in place, triggering user interest and involvement.
The aim of the workshop is to address the following questions around incentives and motivation of Web applications: what is the motivation for a user to (install and) use a tool? Which incentive structures can be applied to the Web, which cannot? Moreover, incentives are a crucial topic for future Web generations: Web paradigms, like the Semantic Web or the 3D Web, that are novel and unfamiliar to end users, aim to involve wide user bases. WEBCENTIVES will attract contributions analyzing, applying, and designing incentive structures for Web applications. We want to emphasize that the workshop also aims at failures, i.e. cases where incentives failed, in order to understand why they failed and to disseminate the lessons learned.

Format

WEBCENTIVES will provide a mix of invited talks, paper presentations selected from submitted papers by a programme committee, demo sessions, and enough time for discussions.
The workshop will be open to all interested parties and aims at bringing together

• researchers investigating content authoring, from collaborative knowledge construction, metadata annotation, social Web, Web 2.0 phenomena, incentives, intrinsic and extrinsic motivation,
• practitioner groups, and
• industry parties that make use of social applications in enterprise environments.

The eventual schedule will be fixed after the selection of the papers and demos.

Objectives

The objective of WEBCENTIVES is to foster the thinking process around incentives, motivations, and benefits of Web applications. We aim at submissions that

• Analyse incentives of existing Web applications,
• Apply incentives to Web applications, and
• Propose and create new incentive structures for Web applications.

Topics include, but are not limited to:

• Motivations and incentives of Web 2.0 applications
• Cost – benefit analyses
• Suggestions how those motivations can be applied in Web applications
• Incentive structures both within enterprise intranets and the open Web
• Games for generating content
• Tools exploiting collective intelligence and the “Wisdom of Crowds”
• Community-driven applications
• Monetary and non-monetary rewards
• Social applications in general
• Empirical studies on the usage of Web 2.0 or social Semantic Web applications
• Social rewards
• Monetary incentives and rewards
• Understanding and creating social reward mechanisms
• Reputation systems and Identity and Social networks for reputation

Review process and submission

We aim at three different kinds of submission: (1) research papers of the length of no more than 8 pages (ACM style) presenting mature work, early prototypes and methodologies, (2) position papers of the length of 4 pages presenting early work and elaborated ideas, and (3) demo outlines of the length of 2 pages.
The submitted papers will be reviewed by 3 reviewers each in a semi-blind review process. We will use the Easychair submission system for that purpose.

Please submit your papers here: http://www.easychair.org/conferences/?conf=webcentives090

Incentives for attending and submitting to the workshop

All accepted papers will published with the conference. We will also invite a selection of the accepted papers to be published at a special issue of the International Journal of Knowledge Engineering and Data Mining (IJKEDM).

Furthermore we plan to invite a proliferate speaker to present as an invited speaker to the workshop to provide an excellent forum for the discussion of this important topic.

It has also to be noted that the workshop's location is Madrid, which is famous for its beautiful parks and museums. April is a wonderful time to enjoy Spain.
