In one of my previous posts, I had discussed the value and importance of TREC to the legal community. Clearwell Systems has been a TREC participant for the last two years, and believes in working with the rest of the participants in advancing the collective knowledge of electronic discovery-related information retrieval methodologies. TREC’s work has been conducted in the context of annual workshops, and is organized in the form of specific tracks. For legal professionals, the TREC Legal Track is the most relevant, and track organizers have just released the much-awaited overview of the 2009 workshop. I will summarize the key results from the study and its broader implications. The overview paper is now available and covers the design of the two tasks within the track – the Interactive task and the Batch task. The Interactive Task is very relevant for the legal community, since it is designed specifically for analyzing the task of producing specific records in response to a “discovery request”. As noted in the paper, 15 teams participated, including 10 commercial teams, up from three teams in 2008. The 2009 study was also the first time an email collection (based on Enron emails released by FERC) was used. The Interactive Task involves a “mock complaint” and seven different topics, with each topic described in the form of a general information request. Several teams participated by choosing one or more topics and submitting responsive documents for each. These were then assessed using a mathematically sound sampling and estimation methodology, and effectiveness metrics were computed for each team.
