A traditional classification scheme based on Aristotelian categories yields search results that are more exact. Traditional cataloging can be more time consuming, and is by definition more limiting, but it does result in consistency within its scheme. Folksonomy allows for disparate opinions and the display of multicultural views; however, in the networked world of information retrieval, a display of all views can also lead to a breakdown of the system.Takes an either-or position. Why not both? Also, seems to make too much about incorrect tagging. If the mass of tags is large enough one incorrect among 1000 correct tags will just get buried. This is only a problem when there is a group effort to supply the bad tag or there are only a small number of tags. There is also the aspect of access for one person or a small group that tagging supplies. The reading list for a class tagged LIS2600 is not much use to most folks but could be very useful to those in the class. Is tagging a replacement for subject analysis? No. Does it provide some access that traditional cataloging misses? Yes. Play around with Library Thing, tags there compliment the LCSH that also exist.
