Authors in proceeding are dominated by one university Recently I want to submit my manuscript to a conference. The accepted papers in this conference will be published in IEEE Xplore, so I thought this conference is reputable. But after I checked the last two years published proceeding (2021 is their 10th), more than 60% of the accepted papers authors are from one university (which is the host of the conference)
As I'm new in academia (as junior lecturer), I'm not sure is this normal and acceptable (the 60%), or is it a sign that the conference not reputable?
Conference reputation is essentially the experiences of the people who have attended the conference.  You have established that only a narrow group of people have attended.  So you know that the conference has an exceptionally narrow reputation.
I would not attend such a conference.
Proceedings for conferences during the COVID-19 pandemic should be disregarded as atypical.
