AIRWeb'09 Topics 2. Organizers and Program Committee 1. AIRWEB'09 TOPICS 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 the following types of submissions on any aspect of adversarial information retrieval on the Web: * Full papers, describing contributions to the field, * Short papers, presenting work in progress, and * Problem statements, explaining relevant, but unsolved or not adequately solved problems. Particular areas of interest include, but are not limited to: * Link spam * Content spam * Cloaking * Blog/forum/wiki spam * Tag spam * Review and rating spam * Click fraud detection * Reverse engineering of ranking algorithms * Web content filtering * Online advertisement blocking * Stealth crawling The proceedings of the workshop will be included in the ACM Digital Library. Full and short papers are limited to 8 and 4 pages, respectively; problem statements will be permitted 2 pages. Papers should be formatted using the WWW 2009 proceedings style (at ) and submitted via . For more information, see 2.
