1. VAST Challenge 2008 Participant Workshop Grand Challenge Summary VAST Challenge 2008 Participant Workshop Sunday Oct 19, 2008 (draft slides included in DVD distributed to participants)

2. VAST Challenge 2008 Participant Workshop Grand Challenge Overview 4 Questions Brought together all four mini challenges 4 Datasets from Mini Challenges –Heterogeneous data Submissions differed in their approach to: –Data integration –Support for analysis –Support for collaboration

3. VAST Challenge 2008 Participant Workshop 6 Participants Penn State & Drexel NEVAC / Composite tools SPADAC, Inc./ Composite tools Palantir Technologies / Palantir Oculus Info Inc. / GeoTime & nSpace2 Vision Systems & Technology, Inc. / Prajna Beijing University of Posts & Telecommunications / GeoTemporalNet

4. VAST Challenge 2008 Participant Workshop Questions for the Grand Challenge Based on ALL the data available (i.e. using the data from all 4 mini - challenges) what is the social network of the Paraiso movement at the end of the time period? What name or names can be associated with individual activities? What is the geographical range of the Paraiso Movement and how does it change over time? How do the major beliefs of the Paraiso movement affect their activities?

5. VAST Challenge 2008 Participant Workshop The Story – Ground Truth See the scenario write up Key are the Paraiso principles: importance of Head of Household, at home medical care, females educated at home. See the Manifesto. Catalano establishes movement on Island; then reaches out to US; boat migration starts Paraiso establishes local presence in FL Conflicts with DOH; incident in Miami; Ramon is a brother of Ferdinando Wiki edits illustrate controversial nature of movement Boat migration shows popularity of movement Cell calls show the social structure of some of the major characters, but also shows how difficult tracking a cell phone is (a structure disappears and is resurrected with other phones) Each mini-challenge is modeled after real situations (e.g., boat migration is very similar to Cuban situation over the years)

6. VAST Challenge 2008 Participant Workshop Data Integration

7. VAST Challenge 2008 Participant Workshop Data Integration Palantir Technologies Dynamic ontology allows disparate data to be combined and searched. Can build structured data from unstructured text. Meta data is stored with entries (can be edited and shared).

8. VAST Challenge 2008 Participant Workshop Data Integration Nevac Association Graph

9. VAST Challenge 2008 Participant Workshop Support for Integrated Analysis No integration –Approach used by a number of teams. Provided means for analysts to analyze each data set but integration of those analyses was left to analysts. Integrated analysis support –Collaboration –Area for analysis

10. VAST Challenge 2008 Participant Workshop Integration of Analysis Oculus Info, Inc. Analysts do separate analysis of minis Share folders which contain sandbox analysis Another analyst can pick this up and combine in another sandbox.

11. VAST Challenge 2008 Participant Workshop Analysis Support Palantir Technologies - History mechanism allows analyst to back up to a previous state. - Using the meta data and the history mechanism, the analyst can generate a Powerpoint presentation. video?

12. VAST Challenge 2008 Participant Workshop Analysis Support Nevac Team Hypotheses can be added as nodes and links into graphs

13. VAST Challenge 2008 Participant Workshop Conclusions Grand Challenge efforts became mostly analytic challenges Need more technical support for: –Integrating data –Integrating analyses –Supporting report generation
