The paper investigates how knowledge structures from a controlled vocabulary affect tagging. The study is a comparative analysis of tags assigned in two tagging systems, a simple tagging system (control system) that provides suggestions from two tag clouds (all users tags and my tags) and an enhanced tagging system (experimental system) that additionally offers suggestions from the Dewey Decimal Classification system (DDC). In the experimental study twenty-eight political students completed four tagging tasks, each comprising fifteen documents. The focus was to examine how suggestions from the enhanced tagging system affect tags as regard tag specificity, exhaustivity, and novelty. Generally, there were no big differences between assigned tags from the two systems. The largest difference was higher degree of tag specificity in the enhanced system indicating that suggestions from a controlled vocabulary might help taggers in being more specific in their tagging, allowing more precise information searching based on user tags. In addition, the results indicate that structured controlled suggestions might encourage taggers to add synonym variations enhancing the variety and number of access points. Furthermore, controlled vocabularies might be useful for automatic spell checking. Future study should explore in what direction the different kinds of suggestions lead the tagger and whether it is possible to identify scope or patterns between related tags from the two systems.
