-The [International Symposium on Open Collaboration](http://www.opensym.org/) (*OpenSym*, formerly *WikiSym*) is the premier academic venue exclusively focused on scholarly research into open collaboration. OpenSym is an [ACM](http://www.acm.org/) conference which means that, like conferences in computer science, it's really more like a journal that gets published once a year than it is like most social science conferences. The "journal", in this case, is called the *Proceedings of OpenSym* and it consists of all the papers presented there. Papers that are published in the proceedings are not typically published elsewhere.

-Along with [Claudia Müller-Birn](https://www.clmb.de/) from the [Freie Universtät Berlin](http://www.fu-berlin.de/), I served as the *Program Chair* for OpenSym 2017. For the social scientists reading this, the role of program chair is similar to being an editor for a journal. My job was *not* to organize keynotes or logistics at the conference—that is the job of the General Chair.  Indeed, in the end I didn't even attend the conference! Along with Claudia, my role as Program Chair was to recruit submissions, recruit reviewers, coordinate and manage the review process, make final decisions on papers, and ensure that everything makes it into the published proceedings in good shape.

 Over the years, OpenSym has established a clear set of niches. Although we eliminated tracks, we asked authors to choose from a set of categories when submitting their work. These categories are similar to the tracks at OpenSym 2016. Interestingly, a number of authors selected more than one category. This would have led to difficult decisions in the old track-based system.

+### Page Lengths

 
 In previous years, OpenSym followed most other venues in computer science by allowing submission of two kinds of papers: full papers which could be up to 10 pages long and short papers which could be up to 4. Following some other conferences, we eliminated page limits altogether. This is the text we used in [the OpenSym 2017 CFP](https://perma.cc/87QY-27FS):
 
 > There is no minimum or maximum length for submitted papers. Rather, reviewers will be instructed to weigh the contribution of a paper relative to its length. Papers should report research thoroughly but succinctly: brevity is a virtue. A typical length of a “long research paper” is 10 pages (formerly the maximum length limit and the limit on OpenSym tracks), but may be shorter if the contribution can be described and supported in fewer pages— shorter, more focused papers (called “short research papers” previously) are encouraged and will be reviewed like any other paper. While we will review papers longer than 10 pages, the contribution must warrant the extra length. Reviewers will be instructed to reject papers whose length is incommensurate with the size of their contribution.

-Although, I won't post any analysis or graphs, bidding worked well. With only two exceptions, every single assigned review was to someone who had bid "yes" or "maybe" for the paper in question and the vast majority went to people that had bid "yes". However, this comes with one major proviso: people that did not bid at all were marked as "maybe" for every single paper.

 Given a reviewer pool whose diversity of expertise matches that in your pool of authors, bidding works fantastically. *But everybody needs to bid*. The only problems with reviewers we had were with people that had failed to bid.

-It might be reviewers who don't bid are less committed to the conference, more overextended, more likely to drop things in general, etc. It might also be that reviewers who fail to bid get good matches become less interested, willing, or able to do their reviews well and on time.

 Having used bidding twice as chair or track-chair, my sense is that bidding is a fantastic thing to incorporate into any conference review process. The major limitations are that you need to build a PC before the conference (rather than finding the perfect reviewers for specific papers) and you have to find ways to incentivize or communicate the importance of getting your PC members to bid.
