The pace of innovation in these areas has reached a level that requires more than one premier annual venue. WSDM invites original, high quality submissions related to search and data mining on the Web, with an emphasis on practical but principled novel models, algorithm design and analysis, economics implications, and in-depth experimental analysis of accuracy and performance. More details are at http://wsdm2008.org/ . Topics of interests include but are not limited to the following: * Crawling the Web and monitoring change * Text indexing, index caching, query processing * Search engine architecture * Novel query languages * Security and privacy in Web search and mining * Distributed, meta, and peer-to-peer search * Vertical portals and search * Ranking and machine learning for ranking * Personalized search and ranking * User profiling and recommendation systems * Multifaceted and task-driven search * User activity modeling and exploitation * Algorithmic aspects of Web advertising related to sponsored search and content match * Multimedia Web search * User interfaces for search interaction * Search quality benchmarking and evaluation * Social media analysis: blogs and friendship networks * Summarization, clustering, classification of Web data * Wrapper induction * Data integration and data cleaning * Information extraction, slot-filling * Entity and relationship extraction * Sense and entity disambiguation * Discovery-driven Web and social network mining * Web measurements, Web evolution, Web models * Traffic and log analysis * Site-level and other aggregate analysis * Algorithms and systems for Web-scale search and mining Paper Format Papers must report original research not accepted or under submission to any journal or conference with public proceedings (previous submissions in informal workshops or as posters are allowed, but must be indicated). Papers must be formatted according to ACM guidelines and style files to fit within 10 pages, including diagrams and appendices if any. A submitted paper must be self-contained. If absolutely necessary, one or two citations may be flagged as compulsory reading before evaluating the submission. Accepted papers will appear in the conference proceedings published by the Association for Computing Machinery (ACM), and will also be accessible to the general public via the conference Web site. Submissions Papers must be submitted in PDF format to the paper submission Web site. PDF files must have all non-standard fonts embedded. After upload, please check the copy stored on the site. Submissions that do not view or print properly may be rejected without a chance to rectify the problem. Please contact wsdm2008@easychair.org for any questions. Review Process Each paper will be reviewed by at least three regular PC members and one or two senior PC members. Decisions will take into account novelty, technical depth, elegance, practical application, impact, and presentation. For some papers, the PC may ask for clarifications from the authors during an author feedback phase.
