Visual Analytics with Biclusters

Identifying coordinated relationships is an important task in data analytics. For example, an intelligence analyst might want to find three suspicious people who visited the same four cities. However, existing techniques that display individual relationships, such as between lists of entities, require repetitious manual selection and significant mental aggregation in cluttered visualizations to find coordinated relationships.

Spectrum: A Visual Analytics Tool to Explore Logs for VAST Challenge 2015

We present a visual analytics tool, called Spectrum, to analyze the movement and communication log data from VAST Challenge 2015. Spectrum has two views: MoveView and SpectrumView. MoveView gives an overview of the movement logs at a certain timestamp by synthesizing time, location and identity information. It replays movement logs over time and demonstrates communication logs with dynamic links. SpectrumView shows the status of all visitors' activities within a period of time. Each stay of visitors in a location is visualized as a line segment.
