No. Each paper should be evaluated in its own right. If you feel that most of the papers assigned to you have value, you should accept them. It is unlikely that most papers are bad enough to justify rejecting them all. However, if that is the case, provide clear and very specific comments in each review. Do NOT assume that your stack of papers necessarily should have the same acceptance rate as the entire conference ultimately will.
Can I review a paper I already saw on arXiv and hence know who the authors are?Yes. See next bullet below for guidelines.
How should I treat papers for which I know the authors?Reviewers should make every effort to treat each paper fairly, whether or not they know who wrote the paper. For example: It is Not OK for a reviewer to read a paper, think "I know who wrote this; it's on arXiv; they're usually quite good" and accept paper based on that reasoning. Conversely, it is also Not OK for a reviewer to read a paper, think "I know who wrote this; it's on arXiv; they're no good" and reject paper based on that reasoning.
How should I treat arXiv papers?ArXiv papers are not considered prior work since they have not been peer reviewed. Therefore, you should review your AISG workshop short papers independently as if the ArXiv papers didn't exist. Citations to these papers are not required and failing to cite or beat performance of arXiv papers are not grounds for rejection. For example:
