In order to cope with the growth of information complexity, organizations have started to implement various forms of knowledge management applications. Approaches range from file-, data-, information-centric software to information retrieval, search engines, and decision support systems. Thereby, the data presentation plays often a crucial part in making knowledge available in organizational settings. We examine two visualizations and investigate their capabilities to support organizational knowledge and their usability. One is a document-keyword centric graph-based visualization, while the other is person-institute centric. Both were evaluated positively in supporting improvement of organizational knowledge.
