Source documents VANCOUVER, British Columbia -- A Canadian immigration panel is considering whether accused environmental saboteur Tre Arrow can apply for refugee status in Canada. Arrow, 30, who is wanted for fire bombing logging and cement trucks in Oregon, asked the Canadian authorities to remain in Canada as a political refugee at a hearing in Vancouver on Tuesday. A key issue will be whether Arrow is affiliated with a terrorist group, which would immediately disqualify him from receiving refugee status in Canada, authorities said. The Immigration and Refugee Board is scheduled to decide by May 31 whether Arrow is affiliated with the Earth Liberation Front, a group the FBI considers a terrorist organization responsible for scores of attacks on property over the past dozen years. unstructured natural language 1000+ extract entities (GATE [2]) from [3]

The scenario fictional dataset suspicious entity Michael Jones video
VAST contest experience realistic tasks and scenarios real data with virtual thread traditional start - read first exploration - few connections missing entities add missing, remove false
VAST contest experience - results entity modification on the fly utilitiy initial leads and plots useful evidence marshalling view
Critics negative: entity quality lots of screen estate involved workcycle hard start positive: responsibility with the user great visualization intuitive usage
