Marti Hearst recently gave a talk at Google related to the themes in her book. She does a good job of explaining the challenges and opportunities related to interactive information seeking, including design, evaluation, query reformulation, integrating navigation and search, information visualization as it relates to search, and future trends. While most of this is music to the ears of HCIR types, her discussion of collaborative search (around minute 46) is particularly “relevant:” Marti spends a good deal of time on our paper on collaborative search, describing the various models of collaboration and showing some figures from our paper. The talk is on YouTube, the paper is on the web. Questions and comments are very welcome.
