We describe the formulation, construction, and evaluation of predictive models of human information seeking from a large dataset of Web search activities. We first introduce an expressive language for describing searching and browsing behavior, and use this language to characterize several prior studies of search behavior. Then, we focus on the construction of predictive models from the data. W...

Abstract: The path planning and obstacle avoidance are the most important tasks for an autonomous mobile robot moving in an unknown environment. This paper presents a simple fuzzy logic controller which involves searching target and path planning with obstacle avoidance. In this contest, fuzzy logic controllers are constructed for target searching behavior and obstacle avoidance behavior based ...

Individual searching style has a primary effect on searching behavior. The case study method provided data about elements of searching styles through: (1) observation of 47 professional searchers performing their job-related searches; and (2) analysis of verbal and search protocols. Statistical associations among a number of variables reveal three dimensions of searching behavior: level of inte...
