The conference received 184 submissions, and all were reviewed by the Program
Committee. Each paper was assigned at least three reviewers, while submissions
co-authored by Program Committee members were reviewed by at least
five people. All submissions were anonymous, and the identity of the authors
were not revealed to committee members. During the first phase of the review
process, the Program Committee, aided by reports from 142 external reviewers,
produced a total of 611 reviews in all. Then, committee members discussed these
papers in depth over a period of 8 weeks using an electronic messaging system,
in the process writing 1,400 discussion messages. After careful deliberation, the
Program Committee selected 32 papers for presentation. The authors of accepted
papers were given 5 weeks to prepare final versions for these proceedings. These
revised papers were not subject to editorial review and the authors bear full
responsibility for their contents.
