The paper presents our design of a next generation information retrievalsystem based on tag co-occurrences and subsequent clustering. We help usersgetting access to digital data through information visualization in the form oftag clusters. Current problems like the absence of interactivity and semanticsbetween tags or the difficulty of adding additional search arguments aresolved. In the evaluation, based upon SERVQUAL and IT systems qualityindicators, we found out that tag clusters are perceived as more useful thantag clouds, are much more trustworthy, and are more enjoyable to use.
