SIGIR 2014 Workshop on Temporal, Social and Spatially-aware Information Access (#TAIA2014)

Spatial and temporal context are increasingly important as users rely more on mobile devices to access information on the Web. Although information access applications are becoming more context-savvy, users' expectations are far ahead of current capabilities. For example, users expect a given application to understand the nature of their current immediate surroundings, while many systems have trouble drawing an accurate map of a city, or assigning a geographic and temporal scope to a web document. Successfully incorporating spatial and temporal context into the retrieval and user models for a system opens up a universe of hyperlocal scenarios.

Users provide an unprecedented volume of detailed, and continuously updated information about where they are, what they are doing, who they are with, and what they are thinking and feeling about their current activities. The provision of this stream creates an informal contract between the user and the information access application that the user will provide the information, but the application must provide results that are contextually relevant. Many of the research questions about how to understand and employ user context have yet to be answered.

In this workshop we explore spatial and temporal context in dynamic geotagged collections, such as Wikipedia, and traditional news sources, as well as social media sites such as Twitter, Foursquare, Facebook and Flickr. To ground the workshop, and provide a locus for discussion of the two aspects of user context, we focus on event detection and recommendation. Events are a natural theme around which to center discussions of spatial and temporal context because events are defined by their time and place. We aim to bring together practitioners and researchers to discuss their recent breakthroughs and the challenges with addressing spatial and temporal information access, both from the algorithmic and the architectural perspectives. This workshop would be a successor to the successful SIGIR 2012 and 2013 Workshops on Time Aware Information Access (#TAIA2012#TAIA2013). 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 the 2013 workshop was on the many time-aware benchmarking activities in 2013. The focus this year will be spatial and temporal information, around the locus of event detection and recommendation.

Important Dates

  • Submission Deadline: Monday, May 19th 2014 (23:59UTC-11; Samoa time zone)
  • Acceptance Notifications: Monday, June 9th 2014
  • Camera-ready Deadline: Friday, June 20th 2014
  • Workshop: Friday, July 11th 2014


Workshop Format

We plan a full day workshop, which will include 2-3 keynote speeches from a combination of industry and academia, and several talks of 20-30 minutes from accepted papers. We will publish a call for papers inviting submissions to the workshop. The workshop will be open to all registered SIGIR participants. The program will be accessible to people with a general IR background, who are new to spatial and temporal information access. At the same time, because the program centers around invited talks and a panel discussion, it will still be interesting for those who have already done significant work in related areas.

Call for Papers

We will welcome submissions related to all aspects of geographical and time-sensitive information access. TAIA 2014 will have a special focus on events, to include event detection, recommendation, and characterization. Research questions include:

  1. How can we detect events in social media?
  2. How can we best leverage our understanding of a user's location and time context to improve the ranking of places and content?
  3. How can we employ models of user generated content to describe places people visit?
  4. Can we construct a pro le of places of interest of users based on their social media streams?
  5. How can we detect and signal significant changes in such profiles?
  6. How can we model the footprint of a business from user social tagging behavior?
  7. How can we model the impact on a business based on users' online behavior?

In addition, TAIA 2014 welcomes contributions on the following issues that complement current technologies in spatial and temporal information:

  1. Publicly available dynamic collections (e.g. Wikipedia edits, Wikipedia page requests, Twitter and news streams).
  2. Evaluation methodologies for geo-constrained and time-sensitive tasks.
  3. Timeline creations and summarizations
  4. Spatial modeling of social media and Web content
  5. Spatial and temporal intent classification of queries
  6. Spatial and temporal natural language processing tasks and techniques
  7. Spatial and time-sensitive ranking, including, effective ranking for spatio-temporal context-sensitive queries, optimizing for both freshness and relevance, evaluating the results for context sensitive queries, etc.
  8. Temporal changes in document contents.
  9. Understanding Web dynamics, including trends and other temporal analysis on web and social graphs.
  10. Local search and recommendation.


The submissions will be peer reviewed (single-blind) 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 Monday, May 26th, 2014 (extended) 23:59UTC-11; Samoa time zone.

Acceptance notifications will be on Monday June 9th 2014.

Keynote Speakers

Susan Dumais

Susan Dumais is a Distinguished Scientist at Microsoft and Deputy Managing Director of the Microsoft Research Lab in Redmond. She also manages the Context, Learning and User Experience for Search (CLUES) Group. Prior to joining Microsoft Research, she was at Bell Labs and Bellcore for many years, where she worked on Latent Semantic Analysis, techniques for integrating search and navigation, and organizational impacts of new technology. Her current research focuses on user modeling and personalization, temporal dynamics of information, context and search, and gaze-enhanced interaction techniques. She has worked closely with several Microsoft groups (Bing, Windows Desktop Search, SharePoint, and Office Online Help) on search-related innovations. Susan has published widely in the fields of information science, human-computer interaction and cognitive science, and holds several patents on novel retrieval algorithms and interfaces. Susan is an adjunct professor in the Information School at the University of Washington. She is Past-Chair of ACM's Special Interest Group in Information Retrieval (SIGIR), and serves on several editorial boards, technical program committees, and government panels.
