Informaiton Retrieval and Applications, Spring 2016

This course offers an introduction to the principles and concepts in information retrieval (IR), which is fundamental to modern Web search engines.
In addition to Web search, other applications of information retrieval systems will also be described.
This year, the course is offered at graduate-level as well as the International Graduate Program in College of Electrical Engineering and Computer Science (EECS). It's taught in English.

  1. Term Project: paper presentation or system demonstration
    Proposal You are required to submit a proposal for term project one week after midterm exam. May 2, 2016 (Mon.)
    Topics For paper presentations, the paper quality will *greatly* affect your score in term project. Please *carefully* select good papers to read.
    Due to our time limits, we might have to start the term project presentation as early as May 30, 2016 (Mon.).

    * [NOTE] All presentations *must* be finished within the scheduled time slots, which will be the last *four* weeks in this semester. No other time slots will be avbailable.
    The current schedule for term project presentation has been announced. As of Jun. 1, there are 43 teams in total. Please check if there's any mistakes.
    May 30, Jun. 6, 13, 20, 2016
    ReportEach team is *required* to upload the final report after finishing your presentation.
    The final report should contain at least the following:
    1. presentation slides (for all teams), and
    2. source code, installation/execution instructions, team members and task responsibility (for system projects)
