SIGIR 2013 Workshop on Time-aware Information Access (#TAIA2013)

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 online world with the offline world, we observe that the web, both in its composition and use, has incorporated many of the dynamics of the real world.

Few of the problems associated with searching dynamic collections are well understood, such as defining time-sensitive relevance, understanding user query behavior over time and understanding why certain web content changes. Just as static collections often benefit from modeling topics, dynamic collections will likely benefit from temporal modeling of events and time-sensitive user interests and intents, which were rarely addressed in the literature. There have been preliminary efforts in the research and industrial communities to address algorithms, architectures, evaluation methodologies and metrics.

We aim to bring together practitioners and researchers to discuss their recent breakthroughs and the challenges with addressing time-aware information access, both from the algorithmic and the architectural perspectives. This workshop would be a successor to the successful SIGIR 2012 Workshop on Time Aware Information Access (#TAIA2012). Where the 2012 edition was the first to bring together a broad set of academic and industrial researchers around the topic of time-aware information access, the specific focus of this workshop is on the many time-aware benchmarking activities that are on-going in 2013.


Important Dates

  • Submission Deadline (extended): Friday, June 21st 2013 (23:59UTC-11; Samoa time zone)
  • Acceptance Notifications: Monday, July 8th 2013
  • Camera-ready Deadline: Friday, July 12th 2013
  • Workshop: Thursday, August 1st 2013

Workshop Format

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

Call for Papers

We will welcome submissions related to all aspects of time-sensitive information access. TAIA 2013 will have a special focus on evaluation and on the collaborative benchmarking activities that are happening this year:

  1. Temporal summarization (or works in progress for the TREC 2013 task).
  2. Real-time search (or works in progress for the TREC 2013 task), including, real-time trends in social circles, real time events vs. real time queries, aggregated search answers for real-time searches, and other related issues.
  3. Dynamic information extraction and updating (or works in progress for TREC 2013 Knowledge Base Acceleration (KBA) and Temporal Summarization tracks).
  4. Evaluation methodologies for time-sensitive tasks: How can these tasks be approached? Are they measuring the right thing? What do they teach us? What is missing?

In addition, TAIA 2013 welcomes contributions on the following issues that complement today's benchmarking activities and that may inform future versions of these activities:

  1. Publicly available dynamic collections (e.g. Wikipedia edits, Wikipedia page requests, Twitter and news streams).
  2. Temporal changes in document contents.
  3. Timeline creations and summarizations
  4. Temporal natural language processing tasks and techniques
  5. Time-sensitive ranking, including, effective ranking for time-sensitive queries, optimizing for both freshness and relevance, evaluating the results for time sensitive queries, etc.
  6. Understanding Web dynamics, including trends and other temporal analysis on web and social graphs.
  7. Mining and correlating multiple temporal signals (e.g., news streams and query streams)



The submissions will be peer reviewed and must be formatted according to the ACM SIG proceedings template with a maximum length of 4 pages. We welcome both position papers and reports on on-going research. Papers should be submitted online ( by Friday, June 21st, 2013 (23:59UTC-11; Samoa time zone).

Acceptance notifications will be on Monday July 8th 2013.
