Programme committee having over 300 members

Overview of submissionsECML PKDD 2009 received 679 abstract

submissions Finally 422 papers submitted (and not

withdrawn during the reviewing process)Area chairs provided recommendations and

rankingbased on the reviews and discussions among the

reviewersThe three Program Chairs made the final

decision after merging the opinions of the Area chairs

Reviewing process - hierarchical26 Area chairs each responsible for several

related research topicsProgram committee nominated by area chairs

consisting of some 300 renowned researchersTo reduce the efforts of the reviewers1. only two reviews were requested 2. in the event of an inconsistency between the two

assessments a third review was requested3. papers receiving two very positive reviews were considered

for inclusion in the two special journal issues: `Machine Learning' and `Data Mining and Knowledge Discovery‘

4. further review for the candidates for journal5. among the journal papers two best student papers were

selected

Reviewing process – detailsOur aim was to give Area Chairs control of the

process:They recruit their refereesThey bid for papers They allocate the refereesThey lead the resolution of conflicts/discussionsThey rank their batch of papers

Aim was to personalise the reviewing process and ensure all papers given attention of area chair

Reviewing process – detailsSome teething problems (our apologies!):

Had significant number of papers that did not receive bids from Area Chairs

Meant Area Chairs were handling papers they were not expert in and for which they did not initially have ideal reviewers

Delays in allocation process significantly reduced reviewing time

Despite these difficulties Area Chairs and reviewers did a magnificent job – and we believe that our main goal of more personalised reviewing was achieved.

Best Papers: procedurePapers receiving positive reviews were suggested

by the Area chairs as candidates for journal publication

16 papers were suggested; 8 for ML and 8 for KDD

Additional review for each suggested paper, papers ranked, the top seven from each list were selected for a journal publication

In each list:the highest ranked paper is awarded the best paperthe highest ranked student paper is awarded the

best student paper
