User Domain Knowledge and Eye Movement Patterns During Search
نویسندگان
چکیده
Cognitive effort measures inferred from eye movement patterns during textural information search have been correlated with subjective task difficulty and objective measures of task effort. Analysis of the same cognitive effort measurements in an independent user study (n=40) of recall-oriented search in the genomics domain reveals strong correlations with self-assessed domain knowledge. A simple regression model based on these measures was successful in predicting participant domain knowledge. These measurements of cognitive effort during search can be calculated on-the-fly and require only recent eye fixation location and duration. We discuss the potential for real time detection of domain knowledge during information search using this eye movement analysis technique.

Inferring user knowledge level from eye movement patterns
The acquisition of information and the search interaction process is influenced strongly by a person’s use of their knowledge of the domain and the task. In this paper we show that a user’s level of domain knowledge can be inferred from their interactive search behaviors without considering the content of queries or documents. A technique is presented to model a user’s information acquisition p...
متن کاملDynamic Assessment of Information Acquisition Effort During Interactive Search
We present a method to measure some aspects of cognitive effort by a user while reading during a search session. We measured reading eye movement properties and patterns of eye movement in a user study (n=32) of participants carrying out realistic journalism IR work tasks. The results show the cognitive effort measures correlate positively with the information task characteristics that, by hypo...

A user-centered view of interactive information retrieval expands the context relevant to understanding information seeking intent to properties of the user and of their task. Some user properties can be sources of metadata that may be useful for improving information search interactions in context. In particular, certain user physiological data can provide novel metadata. One such source for m...
متن کاملA Queuing Network Model for Eye Movement
Eye movement is a basic human behavior that offers a valuable means to explore human cognitive processes. This article introduces two modeling studies of eye movement. First, random menu search was modeled using a queueing network approach and second, a reinforcement learning algorithm was used to generate various eye movement patterns. Random menu search is a task component involved in many hu...
