Abstract: This short paper addresses the lack of accuracy in tagging systems in comparison with traditional search-engines. Lack of accuracy is caused by the Vocabulary Problems and the nature of these systems which rely on lower number of index terms for each resource. Tagraph, a weighted directed graph of tags, and Tag Qualifiers are proposed to mitigate these problems. Both solutions are based on community contributions, therefore specific procedures such as task routing can be used to take the most advantage of the contributions
