Proceedings of the third ACM international conference on Web search and data mining

We welcome you to the Third ACM International Conference on Web Search and Data Mining (WSDM) held February 3--6, 2010 in New York City. As a premier conference in the field, WSDM 2010 provides a highly competitive forum for reporting the latest developments in the research and application of Web search and data mining. We are pleased to present the proceedings of the conference as its published record. WSDM (pronounced "wisdom") is a young conference for research in the areas of search and retrieval, Web mining, economics implications, and in depth analysis of accuracy and performance of search and mining systems. Although it is only in its third year, it has already witnessed significant growth. As evidence of that, WSDM 2010 received a record 290 submissions, representing a 70% increase compared to WSDM 2009. The conference accepted 45 papers (15.5%). The authors of submitted papers come from 35 countries and regions. Authors of accepted papers are from 11 countries.
