What is Information Fostering?

  • Providing proactive support for seeking, sharing, and making sense of information.
  • Suggesting questions to ask and answering the questions you should be asking.
  • Giving you guidance for the future that you may not know exists.

  

Information Fostering is currently being funded through the National Science Foundation (NSF) grant III-1717488, awarded to Dr. Chirag Shah.

Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation.
 
Dr. Shah received Amazon Research Award for project "Addressing Cold Start Problem in Personalization and Recommendation Using Proactive Information Retrieval" (February 2019-January 2020; $100,000). This will complement and help expand the work being done under the NSF-funded project.

Research Outcomes

  • A new framework for proactive recommendations: Reported in a Perspective Paper at ACM CHIIR 2018.
  • Task Model: Reported in papers at ACM SIGIR 2018, ACM ICTIR 2018, and ACM SIGIR 2019.
  • Problem-Help Model: Currently under review for a major journal.
  • Coagmento (a free, open-source tool) for conducting interactive IR and user studies: Presented at ACM CHIIR 2019.

Current Research Activities

  • We are doing more analysis using the data generated by a user study we recently completed. This work has already generated interesting results for creating a Problem-Help Model, which is under review.
  • Exploring reinforcement learning as a method to connect Task Model, Intention Model, and Problem-Help Model to recommendations -- first, reactive, and eventually, proactive.

Past Research Activities

  1. Information seeking barriers, failures, and solutions. In an effort to understand where people fail in information seeking situations and how to best help them, even when they don't explicitly ask for help, we collected data from a qualitative survey involving 208 real-life examples of information seeking failures. In addition, 10 semi-structured interviews with 10 different participants were analyzed using various theoretical frameworks of tasks, strategies, and barriers.
  2. Generative query recommendations. Sometimes, to help an information seeker, we need to go beyond just incremental changes to their existing expression of information need. This is where we have developed new techniques for generating queries that allow a searcher to make a leap rather than just a step. Given a user’s past queries, we model their past queries as a set of topics and recommended the least explored topic that was still relevant to their search, according to a threshold criterion. We then generate multi-word query terms from this topic, using a skipgram model that could create coherent phrases.
  3. Strategy recommendations. We have conducted research in recommending strategies (a sequence of steps involving queries, documents, and relevant information) for exploratory search tasks. We were able to accurately predict the performance of a user a few steps ahead within their search, and moreover could offer effective recommendations. The recommendations offered became more effective as the recommendations were given later in the search process. They moreover greatly enhanced user performance, according to quantitative simulations and qualitative judgments of the simulations and user performance.
  4. Collaborator recommendation. Some times, to help someone in their information seeking process, we should recommend a person to collaborate with. Using 120 participants in 60 pairs working on an exploratory search task, we built a model for finding suitable collaborators for an individual during different stages of his/her search. This model was then tested on real-life data obtained from Bing search logs and Internet Explorer browser logs. The data consisted of 8,969 search sessions by 8,051 users who were working on an exploratory search task during the overlapping timeframe.
