I can't tell you what i found: problems in multi-level collaborative information retrieval

In this position paper, we describe the unique challenges of collaborative information retrieval (MLCIR) in an environment where information access and visibility is not equal across all participants. We call this multi-level collaborative information retrieval, after the term used to describe an environment with differing classification levels. In contrast to traditional collaborative information retrieval, which focuses on technologies to facilitate dynamics in a group, MLCIR must be aware of the information flow in a group, making sure there is not information contamination and inadvertent disclosure of information, while still allowing for collaboration. We cover some of the challenges, and discuss impact on not just formal MLCIR domains, but also more traditional collaborative information seeking domains.
