Adversarial Information Retrieval addresses tasks such as gathering,
indexing, filtering, retrieving and ranking information from
collections wherein a subset has been manipulated maliciously. On the
Web, the predominant form of such manipulation is “search engine
spamming” or spamdexing, i.e., malicious attempts to influence the
outcome of ranking algorithms, aimed at getting an undeserved high
ranking for some items in the collection.

We solicit both full and short papers on any aspect of adversarial
information retrieval on the Web. Particular areas of interest
include, but are not limited to:

* Link spam
* Content spam
* Cloaking
* Comment spam
* Spam-oriented blogging
* Click fraud detection
* Reverse engineering of ranking algorithms
* Web content filtering
* Advertisement blocking
* Stealth crawling
* Malicious tagging
* Ping spam

Proceedings of the workshop will be included in the ACM Digital
Library. Full papers are limited to 8 pages; work-in progress will be
permitted 4 pages. Papers should be formatted using the WWW2008
proceedings style and submitted via

Last year we introduced a novel element at the workshop: a Web Spam
Challenge for testing web spam detection systems. We will be holding
the Web Spam Challenge again this year, using the WEBSPAM-UK2007
collection for Web Spam Detection

The collection includes large set of web pages, a web graph, and
human-provided labels for a set of hosts. We will also 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 2008
