16. Status Report on VLDB J. August 31, 200516 How do we do? Quality Has the highest impact in ISI citation index ranking in the category of “Computer Science, Information Systems” VLDB J.(4.545), TOIS(3.533), Information Systems(3.327), TODS(1.957), TKDE(1.223), etc. Erhard Rahm’s study shows significant increase in references after 2000 The paper downloads have increased substantially

17. Status Report on VLDB J. August 31, 200517 How do we do? (cont’d) Review process Review times are still long, with significant variability We are trying hard to shorten it Accessibility Presence in ACM Digital Library helps enhance accessibility

18. Status Report on VLDB J. August 31, 200518 Discussion Point Journals vs. Conferences

19. Status Report on VLDB J. August 31, 200519 Conferences Fast dissemination is the biggest merit We are concerned about “papers being lost in the noise” (Good papers are rejected) But, we also have to worry about incomplete/incorrect papers being accepted (Bad papers are accepted) Papers claim fancy things, but there is insufficient or faulty proof that they work; experiments are not credible This problem is becoming more serious as the review quality of the papers is degrading  Problems: Many papers tend to be incorrect or incomplete  Reasons: Conferences lack the processes of revision and rebuttal

20. Status Report on VLDB J. August 31, 200520 Journals handle these problems more properly by interactions between the authors and reviewers through a thorough revision process (typically, two rounds) Authors have good chances to have potentially incorrect reviews rectified through a rebuttal process These processes are essential since correctness and completeness are of prime importance for archival journals Bad side: slow dissemination By the time you are rejected in two years, someone else has published an incomplete version of a similar idea in a conference Journals

21. Status Report on VLDB J. August 31, 200521 Inherent Differences Conferences fast dissemination allowing some immaturity Journals archival purposes requiring correctness and completeness

22. Status Report on VLDB J. August 31, 200522 Bridging the Gap between Journals and Conferences Journals Trying to shorten the review time On-line availability helping fast dissemination Conferences Allowing revisions (e.g., rolling over some rejected papers to the same referees) Allowing rebuttals (e.g., permitting author feedback as in SIGMOD 2005)  We are making some progress, but complete merger remains a major challenge
