Web search engines are powerful tools that enable users to explore the rich information available on the world-wide web. While search engine design started as an engineering challenge, it has evolved into a thriving research area. The heterogeneity and volume of the data processed by search engines as well as the diversity of their user population have formed a fertile ground for the emergence of fascinating research problems. These problems call for the expertise of researchers from almost all fields of computer science.

The Search track welcomes contributions related to any area of Web search, including but not restricted to the following:

  • Search engine infrastructure: crawling, indexing, and query processing
  • Generic search platforms such as Map-Reduce
  • Matching and relevance ranking of web documents
  • Search advertising and contextual advertising: serving infrastructure, matching, relevance ranking, etc.
  • Vertical search: multimedia, blogs, news, research papers, e-commerce, etc.
  • Search engine evaluation and measurements
  • Search user interfaces: natural language interfaces, summarization, suggestions, etc.
  • Personalized search
  • Negative content filtering: spam, porn, viruses, etc.
  • Multiple collections: metasearch, rank aggregation, different media
  • Query log analysis
  • Semantic search: entity retrieval, geo/temporal search, sub/super-documents, etc.
  • Query and search user modeling
  • Multifaceted search
  • Distributed and peer-to-peer search
  • Enterprise and desktop search
  • Security and privacy in web search
  • Search and standards: RSS/ATOM, OpenSearch
  • Novel search paradigms
  • Search as an enabler of higher-level applications: implicit search, mashups, etc.

The program committee will give preference to papers focusing on core search technology over papers that focus on related areas, like theoretical computer science.

Paper formatting requirements are provided on the Submission page.
