2. WEB SPAM CHALLENGE

This year, we are introducing a novel element: a Web Spam Challenge for
testing web spam detection systems. We will be using the WEBSPAM-UK2006
collection for Web Spam Detection <http://www.yr-bcn.es/webspam>.

We provide a set of features extracted from the contents and links in
the collection, which may be used by the participant teams, in addition
to any automatic technique they choose to use.  We ask that participants
of the Web Spam Challenge submit predictions (normal/spam) for all
unlabeled hosts in the collection. Predictions will be evaluated and
results will be announced at the AIRWeb 2007 workshop.

The Web Spam Challenge is supported by the EU Network of Excellence PASCAL
Challenge Program and by the DELIS EU-FET research project. For more
information, see <http://webspam.lip6.fr/>

3. STUDENT GRANTS

These grants are possible by a sponsorship from Microsoft.

Students who author or co-author accepted papers at AIRWEB 2007,

Up to three students will be supported, with an expected level of
