 eventSecond ACM International Conference on Web Search and Data Mining - WSDM 2009
WSDM (pronounced "wisdom") is a young ACM conference intended to be the publication venue for research in the areas of search and data mining. Indeed, the pace of innovation in these areas prevents proper coverage by conferences of broader scope. ...

 introduction Ricardo Baeza-Yates: Welcome and Introduction to WSDM 2009

Invited talk:

 invited talk Gerhard Weikum: Harvesting, Searching, and Ranking Knowledge from the Web
There are major trends to advance the functionality of search engines to a more expressive semantic level. This is enabled by employing large-scale information extraction of entities and relationships from semistructured as well as natural-language Web sources. In addition, harnessing ...


 keynote Jeffrey Dean: Challenges in Building Large-Scale Information Retrieval Systems
Building and operating large-scale information retrieval systems used by hundreds of millions of people around the world provides a number of interesting challenges. Designing such systems requires making complex design tradeoffs in a number of dimensions, including (a) the number ...

 lecture Paul Heymann, Hector Garcia-Molina: Contrasting Controlled Vocabulary and Tagging: Do Experts Choose the Right Names to Label the Wrong Things?
Social cataloging sites—tagging systems where users tag books—provide us with a rare opportunity to contrast tags to other information organization systems. We contrast tags to a controlled vocabulary, the Library of Congress Subject Headings, which has been developed over several ...

Most studies on tags focus on collaborative tagging systems where each resource (e.g., article, photo) can be tagged by multiple users with multiple tags. The tag usage patterns in self-tagging systems where a resource (e.g., a blog post) can only ...

 lecture Bruno Gonçalves, Mark R. Meiss, José Javier Ramasco: Remembering what we like: Toward an agent-based model of Web traffic
Analysis of aggregate Web traffic has shown that PageRank is a poor model of how people actually navigate the Web. Using the empirical traffic patterns generated by a thousand users over the course of two months, we characterize the properties ...
 lecture Chinmay D. Karande: Speeding up Algorithms on Compressed Web Graphs
 lecture Ioannis Antonellis, Hector Garcia-Molina, Jawed Karim: Tagging with Queries: How and Why?
Web search queries capture the information need of search engine users. Search engines store these queries in their logs and analyze them to guide their search results. In this work, we argue that not only a search engine can benefit ...

 lecture Irem Arikan, Srikanta Bedathur, Klaus Berberich: Time Will Tell: Leveraging Temporal Expressions in IR
Temporal expressions, such as between 1992 and 2000, are frequent across many kinds of documents. Text retrieval, though, treats them as common terms, thus ignoring their inherent semantics. For queries with a strong temporal component, such as U.S. president 1997, ...
