A data visualisation project to address the data quality and lineage issues in sensemaking using provenance, using the TimeSet technique.
This paper describes a new method designed for temporal visualization with ‘set’ information. Here the ‘set’ can be different ‘theme’ or ‘topic’, such as person, location, organisation, etc. It was selected as the journal cover! More information here
The paper is accepted at VAST 2015, and later appeared in the journal TVCG. It introduces a new tool that can save a lot time doing the transcription and coding when analysing the data collected from qualitative studies such as thematic analysis. More details here
The project designs, implements, and evaluates new Visual Analytic tool for Pattern-of-Life analysis, which tries to understand and predict movement patterns of individuals or small groups.
This is the outcomes from the analytic provenance workshop organised at VIS 2014. It provides an overview of the research related to analytic provenance and the challenges/open problems it faces (a lot). PDF (IEEE digital library Xplore)
A project to build the Big Data infrastructure /Data Lake for the visual analysis of open-source intelligence data.
This is a detailed report of our winner entry to the VAST challenge 2012.
I am co-chairing a workshop on Provenance and Sensemaking at the IEEE VIS conference week in Paris. The submission deadline has now passed, but you can still join the discussions at the workshop during the conference. Hope to see you there!
A data visualisation project to understand how interactive projection technique can help user improve their understanding of data with very high dimensionality.
This year, the Visual Analytics challenge organised by the IEEE VAST (Visual Analytics Science & Technology) conference again had a mini-challenge on Twitter data, and it is (near) real-time this time. The task is to monitor the Twitter feed and provide (near) real-time updates on important events that are happening and find information related to a […]
