We invite research contributions for the 26th World Wide Web Conference Search Track.

We invite original research submissions addressing all the aspects of search, from: complex efficient web-scale systems; to email/calendar search; to search across/within apps, including novel applications.

Relevant topics include, but are not limited to:

  • Adversarial search: spam and abuse issues, link farms, etc.
  • Evaluation methodologies and metrics, including click analysis, online and offline approaches, implicit signals, user models, collection construction, etc.
  • Indexing Web content: text, metadata, semantic and social annotations, etc.
  • Interactive search: query suggestion/completion, search assistance applications
  • Mobile and local search
  • New search paradigms and applications: implicit search, zero query search, task-based search, collaborative search, real-time search, crowdsourcing in Web search, etc.
  • Personalized or context-aware search and ranking including privacy-aware search
  • Query analysis: segmentation, intent prediction, enrichment, rewriting, etc.
  • Query processing: caching and pruning strategies, efficiency issues
  • Relevance ranking: relevance feedback, rank aggregation, diversity, ranking fresh results, integration of search verticals, etc.
  • Search engine architecture and scalability: index compression and organization, distribution, federated and selective search, fault tolerance, pruning and approximation heuristics, etc.
  • Search result presentation: snippet generation, direct answers, interactive results, SERP generation, etc.
  • Semantic search: entity retrieval, geo/temporal search, entity and knowledge graph for Web search and applications
  • User studies involving search and applications, including both in-laboratory and in-wild observations
  • Vertical and specialized search: enterprise, multimedia, social media, news, dynamic content, email, academic, e-commerce, etc.
  • Web IR: blog and microblog search, forum search, community-based QA, etc.
  • Web search models and ranking: probabilistic retrieval models, language models, learning to rank, meta-search and resource selection, diversity and aggregated search, etc.
