Towards More Intelligent Mobile Search

Karen Church, Mark T. Keane, Barry Smyth
2005 International Joint Conference on Artificial Intelligence  
Instead we evaluate an alternative approach involving the use of related queries in place of snippet text for result gisting.  ...  In this paper we argue that the standard Web search approach of providing snippet text alongside each result is not appropriate given the interface limitations of mobile devices.  ...  It is interesting to consider whether these related queries could be used as an alternative to snippet text to gist search results, especially given the interface limitations of mobile devices.  ...

Human performance measures for video retrieval

Gary Marchionini
2006 Proceedings of the 8th ACM international workshop on Multimedia information retrieval - MIR '06  
In this paper, we describe the challenges of assessing human performance during video retrieval episodes and describe several measures of human performance that have been used in developing visual surrogates  ...  These include two sets of cognitive performance measures that aim to assess human recognition and inference and a set of attitudinal measures that aim to assess user satisfaction with video surrogates.  ...  Barbara Wildemuth, Gary Geisler, and Meng Yang and other members of the Open Video Project team developed and applied these measures.  ...
