CALL FOR PAPERS

Workshop on Models of Trust for the Web (MTW'06)
(http://www.l3s.de/~olmedilla/events/MTW06_Workshop.html)

Edinburgh, Scotland, May 22, 2006
in conjunction with the 15th International World Wide Web Conference


Workshop Outline
----------------

    "There are three types of lies - lies, damn lies, and facts found
	on the Web."
    Dr. Tim Finin, paraphrasing the well known quotation by 
    Benjamin Disraeli on Statistics
	  
As it gets easier to add information to the web via html pages, wikis, 
blogs, and other documents, it gets tougher to distinguish accurate 
information from inaccurate or untrustworthy information. A search
engine query usually results in several hits that are outdated and/or 
from unreliable sources and the user is forced to go through the 
results and pick what she/he considers the most reliable information 
based on her/his trust requirements. With the introduction of web 
services, the problem is further exacerbated as users have to come up 
with a new set of requirements for trusting web services and web 
services themselves require a more automated way of trusting each 
other. Apart from inaccurate or outdated information, we also need to 
anticipate Semantic Web Spam (SWAM) -- where spammers publish false 
facts and scams to deliberately mislead users. This workshop is 
interested in all aspects of enabling trust on the web.

This workshop will bring together researchers and experts from 
different communities (e.g., Information Systems, Database, Semantic 
Web, Web Services) interested in topics like trust, provenance,
privacy, security, reputation and spam, in order to address current
challenges of their application to distributed environments like the
Web. The workshop will deliver a state-of-the-art overview,
successful research advances in the area as well as guidelines for 
future research.
