Slides from my presentation at the ECIR 2012 workshop on "Information Retrieval Over Query Sessions" (SIR2012) held in Barcelona, Spain.
Title: Exploring Session Search
Exploratory search is typically characterized by recall-oriented information needs and by uncertainty and evolution of the information need. As searchers interact with the system, their understanding of the topic evolves in response to found information. These two characteristics – uncertainty of information need and the desire to find multiple documents – drive the need to run multiple queries. Furthermore, these queries are not independent of each other because they often retrieve overlapping sets of documents. Yet traditional information retrieval systems often treat searchers’ queries in isolation, ignoring the evolution of a person’s understanding of the information need and the historical coupling among queries.
I this talk, I will describe some interface ideas we're exploring to help people incorporate their search history into their ongoing retrieval and sense-making tasks, and will touch on some issues related to retrieval algorithms and evaluation.
