Collaborative tagging systems allow users to annotate resources using freely chosen keywords, so called tags . Those tags help users in finding/retrieving resources, discovering new resources, and navigating through the system. The process of tagging resources is laborious. Therefore, most systems support their users by tag recommender components that recommend tags in a personalized way. The Discovery Challenges 2008 and 2009 of the European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases (ECML PKDD) tackled the problem of tag recommendations in collaborative tagging systems. Researchers were invited to test their methods in a competition on datasets from the social bookmark and publication sharing system BibSonomy. Moreover, the 2009 challenge included an online task where the recommender systems were integrated into BibSonomy and provided recommendations in real time. In this chapter we review, evaluate and summarize the submissions to the two Discovery Challenges and thus lay the groundwork for continuing research in this area.http://www.bibsonomy.org/bibtex/2c64b98851f270a50717e107d25c9014a/hothohotho2009-09-27T19:51:38+02:002009 challenge conference dc09 ecml myown pkdd <span class="authorEditorList"><a href="/author/Eisterlehner">Folke Eisterlehner</a>, <a href="/author/Hotho">Andreas Hotho</a>, and <a href="/author/Jäschke">Robert Jäschke</a> (Eds.). . </span><em>volume 497 of CEUR-WS.org, </em>(<em>September 2009</em>)Sun Sep 27 19:51:38 CEST 2009sepCEUR-WS.orgECML PKDD Discovery Challenge 2009 (DC09)49720092009 challenge conference dc09 ecml myown pkdd
