1. 1 How to Present a Paper Jun Dong Cho, Sungkyunkwan University Jun Dong Cho, Sungkyunkwan University03/31/2007

2. 2 What to Say and How to Say it Introduction: Topic and purpose - what and why Agenda / Outline Benefits, Informal description Body: weave in supporting strategies as you expand on your agenda Conclusion: Summarize agenda Recap benefits Next steps

3. 3 Define the Problem If the audience doesn’t understand the problem being attacked, then they won’t understand the rest of your talk.

4. 4 Motivate the Audience Explain why the problem is so important. Throw in a little philosophy if necessary. How does the problem fit into the large pictures? What are its applications? What makes the problem nontrivial? The use of terminology and jargon should be kept to a minimum.

5. 5 Discuss Earlier Work Research is not carried out in a vacumm. Be sure to mention the author of each paper and its date of publication Compare and contrast them with each other, and with your paper.

6. 6 Emphasize the Contributions of your Paper Make sure that you explicitly and succinctly state the contributions

7. 7 Provide a Road-map Give a brief guide to the rest of the talk Do not make it a dry litany of dull generalizations (“First I will present the introduction, then summarize earlier work, then present the main body, and end with the conclusion”). Instead, give a short preview of what will be in each section.

8. 8 The Body Abstract the major Results Explain the Significance of the Results Sketch a Proof of the Crucial Results

9. 9 Technicalities Give some technical details Present a Key Lemma Present as succinct and clear as possible

10. 10 Conclusion Hindsight is Clearer than Foresight Regain the attention of the non- experts, who probably did not follow all of the Technicalities section. Leave them feeling that they have learned something nonetheless. Give Open Problems Mention weakness of your paper.

11. 11 Getting through to the Audience Use repetition : Coding theory Do not get bogged down in details You will not be able to communicate all of the details in an oral presentation. The audience would appreciate an overview of the paper so that they can determine whether the paper is worth reading. A good talk motivates the listener into reading the paper and makes the task of reading it easier.

12. 12 Know your Audience Make sure that your talk is at the right level Scientists: Provide more philosophical background. Computer Scientists –Introduce a small technicalities, but keep it brief –Be careful with your definitions –The emphasis should remain on the Introduction and the Body.

13. 13 Theoretical Computer Scientists –The emphasis should be on the Body of the talk. Experts Get right down to the core of the matter. The emphasis should be on the Body and the Technicalities. They are more argumentative. Do not try to cover too much material.

14. 14 Q&A If you are interviewing for a job, the question may be intended to see how you react to criticism under pressure. Expect to have your ego bruised. Attack: “boring, a minor twist to an old technique, there are something more interesting” To be prepared, be polite, and avoid getting involved in a lengthy exchange. It is sometimes advisable to short-circuit such questions by offering to take them off-line Do not be afraid to answer “I don’t know”. Don’t be afraid to approach your questioner after the talk – you might learn something.
