要求描述如下：
A system is required to maintain and manage reviews of technical papers for a large software engineering conference. The system must record details about each paper, including its title, author(s), and contact email address. (Please see appendix 1 for the list
of submitted papers.) A paper should have at least one contact email address. A programme committee (PC), which is guided by a programme committee chair, carries out the reviews of papers. (Please see appendix 2 for the list of PC members). Each PC member is allocated a number of papers by the PC chair. Note that a PC member cannot be assigned a paper where there is a “conflict of interest”, for example, where they are personally related to an author or are themselves an author of the paper. To avoid this, a
record is kept of which authors have a conflict with which papers. Each PC member then reviews their allocated papers, after which they must fill in a review form with detailed comments about the paper and an overall score. The score for a paper is collated from a number of key indicators, for example, novelty, clarity, length, importance and relevance. The reviewer must write comments to the reviewed papers. (Please see appendix 3 for a sample review form).
Once the review process has completed, decisions are made regarding the acceptance of papers. Based on its score, a paper can be rejected or accepted. The PC chair sets the thresholds for accepting/rejecting a paper. A paper is assigned a “voting” status when it is in between the thresholds for acceptance and rejection. In this situation it is up to members of the PC to vote on whether a paper should be accepted. To do this, PC members discuss the merits or demerits of each paper that is being voted on (but they
cannot vote or discuss papers where they have a conflict of interest). PC members can then vote for or against a paper as many times as they like, but only their latest vote is recorded. If they do not vote for a paper no vote is counted. Finally, once a certain time period is over, the votes are counted. Papers that gain more votes for acceptance than votes for rejection are accepted.
