Abstract: A method for detection of spam in a tagging system can include assigning negative points to each tag in the tagging system responsive to the tag matching at least one spam filter criteria, assigning trust points to a tagger responsive to the tagger's behavior matching at least one tagger filter criteria, wherein the at least one tagger filter criteria depends upon tags assigned by the tagger that are assigned negative points, and restricting a tagging functionality of the tagging system for a tagger if a first predefined threshold of negative trust points is exceeded.

Abstract: A method, system, and computer program product for federating tags across multiple web-based systems in order to provide an improved tag management system which allows users of a community to upload their contributions to the content of the content server systems, including uploading their tags. The method includes: storing tags in a central database, wherein the central database accesses the resources and the tags of the multiple systems; retrieving all tags from the central database; displaying the tags to a user; receiving a search request by the user, wherein the user search comprises selection of specific tags or specification of tag search criteria; generating a tag cloud containing references to tag-associated resources which result from the search, wherein the resources may reside in any one of the systems; and displaying the resources.

Abstract: In order to provide an improved tagging-based search method, the method includes one-click actions for searching as well as an “one view” indicator telling the user which search would be the most effective or most important search—by displaying a “search cloud”, called search bag.
