What is peer review?
• Corner stone of science• Process to evaluate the quality of a scientist’s
research• By peers• Reviewers and decision makers • Peer Review Process for Scholarly Publication
![Page 3: Scientific Peer Review Yixin Chen, Associate Professor Computer & Information Science University of Mississippi April 9, 2013](https://reader036.vdocument.in/reader036/viewer/2022082510/5a4d1b457f8b9ab0599a30b9/html5/thumbnails/3.jpg)
Why do scientists want to publish?
• I did/discovered/proved it the first.• You may create a permanent record with your
name• Promote research interest • “Publish or perish”• Reputation of a journal

Peer Review Process
• An “interesting” research question.• Due diligence• Do your research• Find a “right” place to publish• Document your discovery

Peer Review Process
• Journal Editor• Associate Editor• Reviewers• 4 weeks later …• Associate Editor– Accept without changes / Accept with minor
changes– Major revision / Rewrite and resubmit / Reject

Peer Review Process
• Conference program committee• Reviewers• 4-6 weeks later• Rebuttal• PC chairs make final decision– Accept or reject

Anonymity
• Single-blind review• Double-blind review• Open peer review– arXiv• Perelman’s 2002 proof of Thurston’s geometrization
conjecture• Vinay Deolalikar’s proof of P!=NP in 2010 (unfortunate,
the proof has an error)

The Value of Peer Review
• Quality control• Authors• Journals• Other scientists• Outside the science community

Limitations of Peer Review
• Peer review may not increase the quality of published research
• Peer review is not fraud-detection system– Jan Hendrik Schön
• Does peer review increase the pace of scientific research?

Impact Factor (IF)
• Year Journal Citation Reports• IF = number of citations the papers published
in that journal in the previous two years / total number of papers published in the two years in that journal
• IF should be used cautiously• 5-year IF
