Resource discovery through social tagging: a classification and content analytic approach: Online Information Review: Vol 33, No 3

"This paper aims to investigate if tags are an effective means of resource discovery. Results from the classifiers were mixed, and the inclusion of tags as part of the feature set did not result in a statistically significant improvement (or degradation) of the performance of the SVM classifiers. This suggests that not all tags can be used for resource discovery by public users, confirming earlier work that there are many dynamic reasons for tagging documents that may not be apparent to others."
