Search Among Secrets: Separating the wheat from the buzzsaw
Compartir
A fundamental assumption of nearly all information retrieval research is that content that should not be shown to the user should simply not be included in the collection that is indexed. This assumption breaks down, however, when it is not practical to separate what we want (the “wheat”) from what needs to be protected from disclosure (the “buzzsaw” that can ruin your day). In this talk, I will motivate the problem from four perspectives: multi-level security in enterprise search, scholarly access to personal papers in archival institutions, requests by citizens for access to government records, and withholding of privileged content in the “discovery” process that arises from civil litigation in some jurisdictions. For each of the last three cases, I will describe a research project that sheds some light on requirements, challenges, and capabilities. Iʼll then conclude the talk by offering thoughts on task design, evaluation design, and system design that may help to move us closer to being able to address this increasingly important grand hallenge of search among secrets.
