My colleague Max Wilson at the University of Southampton recently called my attention to a pair of special issues of Information Processing & Management. The first is on Evaluation of Interactive Information Retrieval Systems; the second is on Evaluating Exploratory Search Systems. Both are available online at ScienceDirect. The interactive IR papers can be downloaded for free; the exploratory search papers are available for purchase to folks who don’t have access through their institutions.
I’m behind on my reading, but the titles look promising. Stay tuned!
