Why training and review (partly) break control sets

A technology-assisted review (TAR) process frequently begins with the creation of a control set—a set of documents randomly sampled from the collection, and coded by a human expert for relevance. The control set can then be used to estimate the richness (proportion relevant) of the collection, and also to gauge the effectiveness of a predictive […] → Read More: Why training and review (partly) break control sets

Ego-Centric vs. Exo-Centric Tracking and Interaction in Smart Spaces

In the recent paper published at SUI 2014,”Exploring Gestural Interaction in Smart Spaces using Head-Mounted Devices with Ego-Centric Sensing”, co-authored with Barry Kollee and Tony Dunnigan, we studied a prototype Head Mounted Device (HMD) that allows the interaction with external displays by input through spatial gestures. In the paper, one of our goals was to […] → Read More: Ego-Centric vs. Exo-Centric Tracking and Interaction in Smart Spaces

Total assessment cost with different cost models

In my previous post, I found that relevance and uncertainty selection needed similar numbers of document relevance assessments to achieve a given level of recall. I summarized this by saying the two methods had similar cost. The number of documents assessed, however, is only a very approximate measure of the cost of a review process, […] → Read More: Total assessment cost with different cost models

Information Interaction in Context 2014

I asked FXPAL alumni Jeremy Pickens to contribute a post on the best paper award at IIiX which is named after our late colleague Gene Golovchinsky.  For me, the episode Jeremy recounts exemplifies Gene’s willingness and generosity in helping others work though research questions.  The rest of this post is written by Jeremy. I recently had the opportunity to attend the Information Interaction […] → Read More: Information Interaction in Context 2014
