Computer science publication culture and practices has become an active discussion topic. Moshe Vardi has written a number of editorials in Communications of ACM on the topic that can be found here and here, and these have generated considerable discussion. The conversation on this issue has been expanding and Jagadish has collected the writings on Scholarly Publications for CRA, which is a valuable resource.
The database community has pioneered discussions on publication issues. We have had panels at conferences, discussions during business meetings, informal conversations during conferences, discussions within SIGMOD Executive and the VLDB Endowment Board – we have been at this since about 2000. I wrote about one aspect of this back in 2002 in my SIGMOD Chair‘s message.
The initial conversation in the database community was due to the significant increase in the number of submitted papers to our conferences that we were experiencing year-after-year. The increasing number of submissions had started to severely stress our ability to meaningfully manage the conference reviewing process. It became quite clear, quite quickly, to a number of us that the overriding problem was our over-reliance on conferences that were not designed to fulfill the role that we were pushing them to play: being the final archival publication venues. I argued this point in my 2002 SIGMOD Chair’s message that I mentioned above. I ended that message by stating that we “have been very successful over the years in convincing tenure and promotion committees and university bodies about the value of the conferences (rightfully so), we now have to convince ourselves that journals are equally valuable and important venues to publish fuller research results.” The same topic was the focus of my presentation on the panel on “Paper and Proposal Reviews: Is the Process Flawed?” that Hank Korth organized at the 2008 CRA Snowbird Conference (the report of the panel appeared in SIGMOD Record and can be accessed here).
This discussion needs to start with our objectives. In an ideal world, what we want are:
The conventional wisdom is that conferences are superior on the first two points and the third point is something we can tinker with (and we have been tinkering with for quite a while with mixed results) while the fourth objective is addressed by a combination of increasing conference paper page limits, decreasing font sizes so we can pack more material per page, and the practice of submitting fuller versions of conference papers to journals. Data suggest that the first issue does not hold – our top journals now have first round review times that are competitive with “traditional” conferences (e.g., SIGMOD and ICDE). The second issue can be addressed by adopting a publication business model that relies primarily on on-line dissemination with print copies released once per volume – this way you don’t wait for print processing, nor do you have to worry about page budgets and the like. Note that I am not talking about “online-first” models, but actually publishing the final version of the paper online as soon as the final version can be produced after acceptance. Journals perform much better on the last two points.
In my view, in the long run, we will follow other science and engineering disciplines and start treating journals as the main outlet for disseminating our research results. However, the road from here to there is not straightforward and there are a number of alternatives that we can follow. Accepting the fact that we, as a community, are not yet willing to give up on the conference model of publication, what are some of the measures we can take? Here are some suggestions:
These are things that we currently do – Proceedings of VLDB (PVLDB) incorporates these suggestions. It represents the current thinking of the VLDB Endowment Board after many years of discussions. Although I had some reservations at the beginning, I have become convinced that it is better than our traditional conferences. However, I am suggesting going further:
As I said earlier, my personal belief is that we will eventually shift our focus to journal publications. What I outlined above is a set of policies we can adopt to move in that direction. For an open membership organization such as SIGMOD, making major changes such as these requires full engagement of the membership. I hope we start discussing.
