Visual knowledge exploration and discovery from different points of view

Complex scenario analysis requires the exploration of multiple hypotheses and supporting evidence for each argument posed. Knowledge-intensive organisations typically analyse large amounts of inter-related, heterogeneous data to retrieve the knowledge this contains and use it to support effective decision-making. We demonstrate the use of interactive graph visualisation to support hierarchical, task-driven, hypothesis investigation. The visual investigative analysis is guided by task and domain ontologies used to capture the structure of the investigation process and the experience gained and knowledge created in previous, related investigations.
