Sensemaking in e-discovery • The challenge • When conduct of a company is brought into question... • Investigation - regulatoryor prelude to litigation • Lawyers search, review, sort and re-represent data • A high-recall problem • Construct the narratives that matter from unstructured info. • ... a collaborative sensemaking problem

  3. The problem of manual review • The problem of ‘information inflation’ – a ‘pulse’ in the history of information [Paul & Baron, 2007] • A challenge to effectively identifying the evidentiary record within reasonable constraints of time and cost.

  4. ‘Information inflation’ - challenges tractability • Jeane Thomas, Crowell & Moring • (Keynote at DESI II, 2008) • Mergers and Acquisitions for AT&T • Document requests from US Department of Justice • 1996 – 12 to 15 lawyers – 300 boxes of paper • 2004 – 125 contract lawyers – reviewed 30 million pages and produced 12 million relevant documents • 2005 – 600 lawyers – reviewed 112 million pages and produced 17 million relevant pages

  5. Case studies of regulatory investigations at a London law firm.

  6. ThreadsVI • The construction of narrative is important. • Emails are units of communication. Email threads are higher order-units of communication. • Investigations are people-centric • Wanted... • Visualisation that supported visual indexing by people, emails and threads. • Visualisation that showed thread overlap – i.e. faithful to chronology.

  7. The Enron collection • In October 2003, US Federal Energy Regulatory Commission placed collection of Enron's internal emails from 1999-2002 into the public domain as part of its ongoing investigations. • ~ 500,000 messages belonging to 158 users - mostly senior management. • ~250,000 unique messages. • One of the few or only substantial set of emails available. • Much research has been done with the collection.

  8. Help users shape the flow of information they receive [McNee & Arnette, 2008] • Provide an overview of what’s underneath

  9. Update the dataset and get ThreadsVI going • Downloadhttp://www.eis.mdx.ac.uk/vass/simondatafiles.zip • Save zip file to Desktop/visualindexesdemo/OUT/ • Unzip in that folder (overwrite) • Change the screen resolution to 1152 x 864 • Go to Desktop\VASS\visualindexesdemo • Right click vi-threads.ss • Open with Firefox

  10. Task Context • Facts • Enron filed for bankruptcy in late 2001 • Largest bankruptcy in history • Many debts and losses were not reported • Imaginary Scenario • Enron was funding research at Poppleton University. The money didn’t appear on the books. • You are investigating debts that weren’t declared.

  11. Task • Investigation questions • Did Enron give money to Poppleton? If so what/when? • Who might be responsible for the accounting decisions? What is your evidence for oragainst? • Who would you like to interview and why? • Meta-questions • Record your thinking. What hypotheses did you have? Were they challenged? • What representations did you create? • What additional tools/functionality would you add?
