We recently submitted a paper, and now I'm creating some slides about it for future presentation. There are papers that we have cited in our paper and I need to cite them in slides too because they are directly related to our work. What I would like to do is inline citing when you just mention author's name, or conference name, or the year. I have seen works in which what is mentioned is the first author's family name, e.g. (Patterson, 2013). And I've seen those who just mention conference name and year, e.g. (PPoPP, 2012).
I want to know which one is more appropriate, or actually correct? Where to use one, and where to use the other? Or should I use something different?
