HOW TO READ
RESEARCH PAPERS
Reading papers effectively is
challenging
   Written in a condensed style

   Assuming much prior knowledge

   Written for a different purpose than
    being course materials

   You have limited time
Learning how to read papers
effectively is important
   Life-time long skill of self-learning
    ◦ New knowledge is likely to show up in
      research papers
How to read paper effectively
1.   Know what you should get out of the
     papers

2.   Know where to find them
Structure of a paper
   Introduction
    ◦ Motivation
    ◦ Outline the solution

   Body
    ◦ Solutions in detail
    ◦ Evaluation to show the solutions are valid

   Conclusion
    ◦ Recap
    ◦ Emphasize primary contributions
Questions to answer
1.       What are the motivations for this work?
     ◦       People problem: broader impact on society
             Saved time, increased safety
     ◦       Technical problem
             Why is the people problem difficult?
             Why are previous solutions inadequate?


     ◦        Research problem: what the paper
             addresses
Questions to answer
2.       What is the proposed solution?
     ◦    A hypothesis
     ◦    Why is it believed to solve the problem
     ◦    Why is it better than previous solutions
     ◦    Design and implementation
Questions to answer
3.       What’s the work’s evaluation to the
         proposed solution
     ◦    What argument, implementation, and/or
          experiment shows the solution’s better?
     ◦    What benefits/problems are identified?
Questions to answer
4.       What is your analysis of the identified
         problem, solution, and evaluation?
     ◦    Is it a good idea? Flaws? Controversial?
          Practical?
5.       What are the contributions?
     ◦    Insights on the research question, ideas,
          software, experimental techniques, …
6.       What are the future directions?
7.       What questions are you left with?
Questions to answer
8.       What’s your take-away message?
     ◦    Try to sum up the paper in one sentence
