If the publishing house is well-known such as IEEE, TTP, WIT, etc., it can basically guarantee the retrieval, but no one can guarantee the retrieval time. For example, an author submitted a conference paper in March last year, held a meeting in July and August, and only retrieved it in April this year. Another example is that another author opened it in February last year at 65438 and searched in May this year. According to the general situation, ei conference papers can be retrieved about 3-9 months after the meeting, but the possibility that they cannot be retrieved or have to wait longer is not ruled out.
For graduates or assessors, there is a clear deadline for graduation and title evaluation. The meeting they are going to vote on should play a role. Before arranging the meeting, we should not only consider the retrieval time of the meeting papers, but also consider the authority of the meeting.
