Until now, I never engaged in presenting a conference paper. In the near future, I may likely need to give a seminar on a conference paper. In order to gain knowledge about conference presentations, I watched videos of seminars given by authors of accepted papers of previous years which are available on YouTube.
I can classify the seminars based on the type of questions asked by participants into 3 categories:
No questions from participants;
Questions solely based on the contents of the presentation;
Questions about research that happened a long time ago (say 20 years) that might be related to the presented paper.
The questions of category 3 are generally from domain experts. The questions are along the lines of:
The technique used by your published conference paper (say, on page no:3) seems similar to the technique that has been used in some other paper titled ______ by _____. How is your idea different from their techniques?
In some cases, if the corresponding author, who is presenting the paper, encounters such questions, other people from the audience, probably other authors, responded to the questioner since the corresponding author was not necessarily aware.
In this context, is it proper etiquette to prevent such questions by saying something like the following?
I will gladly answer any questions about the contents that are present in my presentation slides. If there are any other questions, feel free to email me.
