A Comparative Analysis of User-generated and Authorgenerated Metadata for Web Resources

摘要

In this paper, we investigate the difference betweenrnmetadata generated by users and authors. Delicious tags andrnHTML keyword META tags associated with the same setrnof web pages on topics related to semantic web arerncollected, forming two datasets (i.e., Delicious dataset andrnHTML dataset). Comparisons of the two datasets in micrornand macro vocabulary overlap as well as classification ofrnweb pages are analyzed. The results show that (1) overlaprnbetween the two datasets exists; (2) non-overlapped tags inrnDelicious dataset reveal systematic deficiency of socialrntagging systems; non-overlapped tags in HTML datasetrnexpose organization-oriented contents; and (3) Deliciousrndataset tends to cluster web pages according to theirrnpopularity and subject area while HTML dataset clustersrnthe web pages according to different websites/authors.
