2013Q3 Reports: Program Chairs

Program Chairs (Pascale Fung and Massimo Poesio)

This year's ACL introduces a number of innovations, main among which are that this will be the first year in which TACL papers are going to be presented; that mentoring was trialled again; and that a stricter policy regarding registrations was introduced. Handling such innovations as well as the greatly increased number of submissions proved challenging, but in the end not really problematic.

ACL 2013 received a total of 1286 submissions, of which 662 long papers and 624 short papers. (This number of long paper submissions is in line with previous years and in fact slightly lower than in 2011, but the number of short paper submissions is the highest ever - almost twice the 369 of last year, and 20% higher than in 2011.) These submissions were managed by a program committee of 45 area chairs, much larger than in the past (cfr. the 30 area chairs of 2012 and the 27 of 2011), assisted by XXX reviewers. 174 (26%) long papers and 154 (24%) short papers were selected for presentation in the conference. Among the accepted papers, 111 of the long papers will have an oral presentation (in 37 sessions of 3 papers each) as well as 56 of the short papers (in 14 sessions of 4 papers each). In addition, the authors of 16 TACL papers chose presentation at ACL; 9 of these were given an oral presentation and 7 a poster presentation. In total, then, 344 papers will be presented at ACL 2013: 176 orally and 168 as posters. The number of poster presentations is much higher than the 75 of the 2012 edition and the 128 of 2011. We believe the increase in the number of posters is a positive development that may eventually lead to ACL playing a greater community building role; but it will have to be managed in a number of ways, e.g., by ensuring that suitable space is allocated to the posters. (How to handle the number of posters, much exceeding expectations, was one of the main issues we had to face as program chairs. More in general, we recommend keeping program chairs more in the loop regarding venue characteristics - we only learned about the specifics of this year's venue after coming up with a first version of the program, which then had to be substantially revised.)

The submission process in general worked reasonably well, except for the delay caused by Softconf moving to a new platform in October 2012. The new platform aims at reducing the number of distinct Softconf accounts each of us has to keep track of, which is a very good idea, but the fact it only came live in October meant that both us and the area chairs had to invite people twice, first via email and then through Softconf, which was quite painful. (But apart from this difficulty we wish to stress that we were very impressed with the level and speed of support provided by Softconf, which went way beyond the terms of the contract.) The timetable for submissions, developed in close collaboration with both the chairs of NAACL and with ACL exec, worked quite well and we recommend future chairs to follow it quite closely as it will not be easy to find a different solution satisfying all the constraints.

The following table shows the number of submissions in each area for long and short papers, as well as the number of papers accepted in each area.
