I'm curating a list of sources - that makes the dataset easier to deal with, and I think higher quality. In a lot of cases I'm trying to rely on someone else having vetted speakers. E.g. a conference picking speakers, universities hiring good professors, someone recommending a talk on hacker news. I also boost the ranking if a speaker is interesting enough to have a wikipedia page.
