Hi, This is precisely the subject of my PhD: How to asses the quality of information and select online sources. I have a special focus on corporate information specialists but I think it applies to your academic object. To investigate this subject, I've done a two-step fieldwork research. First consist in submitting a list of information quality criteria taken from a book written in 2001. Each criteria had to be rated on its level of importance when applied to 5 specific formats (blogs, wikis, podcasts, file sharing and social network) compared to "classic online sources". For information quality assessement, I have noriced 2 approach. The academic one, that is very broad, concpetual, theorethical, etc. You deal with very interesting things such as authority, timeliness, acuracy, etc... But this is not very useful when applied to a real situtaion. Here, Professional literature provides you with a great help. All thos general criteria are generally declined in checklists of precise questions. For exemple, assessing update is not easy as such but the checklist ask you: is there an expicit date of the information ? is the information up-to-date? is there statement of policy regarding frequency of update? etc. Two references have to be suggested in my opinion: Alexander, J. E. (1999). Web Wisdom: How to Evaluate and Create Information Quality on the Web (p. 156). Mahwah, N.J: Lawrence Erlbaum Associates. Cooke, A. (2001). A Guide to Finding Quality Information on the Internet: Selection and Evaluation Strategies (2 éd., p. 216). London: Library Association Pub. This is research is detailled in Depauw, J. (2007). Dealing with user generated content: Adjusting Information managers' source selection and information quality assessment. Dans Proceedings of The Good, the Bad and the Unexcpected. Moscow: Cost 298. Results are to be presented at IR9.0 - at doctoral colloquium and on Saturday. Paper #306 Depauw, J. (2008). Information quality assessment and source selection on the internet for competitive intelligence: fieldwork research on 53 Belgian executives. Dans Proceeding of Internet Research 9.0: Rethinking Community, Rethinking Place. IT University of Copenhagen: Association of Internet Researchers. The second step of the fieldwork research consists in 15 qualitative interview with respondents of the first step. During this interview, I asked a question that might interest you as I wondered if there are criteria of information quality that are not covered in the list of the study. I don't remember everything I have to say. But I cans share this asap. My dissertation is due to May 2009. I hope this helps. Feel free to contact me off-list if you want more details. I wish you all a nice WE guys, ____________ Jeremy Depauw PhD Student Département des Sciences de l'Information et de la Communication (S.I.C.) Université Libre de Bruxelles (U.L.B.) Avenue F.D.
