SIGIR 2012 Workshop on Time-aware Information Access (#TAIA2012)

Web content increasingly reflects the current state of the physical and social world, manifested both in traditional news media sources along with user-generated publishing sites such as Twitter, Foursquare, and Facebook. At the same time, web searching increasingly reflects problems grounded in the real world.

As a result of this blending of the web with the real world, we observe that the web, both in its composition and use, has incorporated many of the dynamics of the real world. Many of the problems associated with searching dynamic collections are not well understood, such as defining time-sensitive relevance, understanding user query behavior over time and understanding why certain web content changes.

We aim to bring together practitioners and researchers to discuss their recent breakthroughs and the challenges with addressing time-aware search, both from the algorithmic and the architectural perspectives.

Call for Papers

We will welcome submissions related to all aspects of time-sensitive search including, but not limited to the following topics.

  • Classifying queries with temporal intent
  • Effective ranking for time-sensitive queries
  • Optimizing for both freshness and relevance
  • Evaluating the results for time-sensitive queries
  • Aggregated search answers for real-time searches
  • Temporal trends in social circles
  • Temporal dynamics of document contents
  • Time-aware recommendation systems

The workshop will comprise of invited talks, oral presentations and open-forum discussions.

The submissions will be peer reviewed and must be formatted according to the ACM SIG proceedings template with a maximum length of 4 pages. The papers should be submitted online at:

Keynote Speakers

  • Eytan Adar (Assistant Professor, University of Michigan)
  • Rosie Jones (Director of Computational Advertising at Akamai)
  • Neel Sundaresan (Sr. Director & Head, Research Labs at eBay)
