Conf abstracts are NOT papers
Conference presentation usually only publish the abstracts in the meeting proceedings. Since they do not require any peer-review process, thus they are not considered "papers" according to INS.
Also because they are not published by normal peer-reviewed journals, it is not collected by paper databases, like PubMed, ISI, or Google Scholar. Thus no citation will be found. And anyway who will cite only a abstract?
The only thing useful in a conference is the invited speach. If you can provide the initial invitation letter from the conference to ask you to give keynote speech, that really counts!
Good Luck
