In this paper we look at some of the problems in interacting with best-match retrieval systems. In particular, we examine the areas of interaction, some investigations of the complexity and breadth of interaction and attempts to categorise user's information seeking behaviour. We suggest that one of the diiculties of traditional IR systems in supporting information seeking is the way the inform...

This paper outlines a broad research agenda aimed at examining the manner in which individual differences in information seeking behavior interact with the search task to affect search outcomes. As part of this agenda, we describe specific experimentation that will assess the impact of both Need for Cognition (the tendency to elaborate upon, structure and evaluate information) and Selfand Other...

BACKGROUND Two variants in the dopamine D4 receptor (DRD4) gene have been reported to be associated with human approach-related traits such as novelty seeking and extraversion. However, the strength of evidence for this association remains uncertain. METHODS We conducted a meta-analysis of published studies of the association between the DRD4 gene variable number of tandem repeats (VNTR) and ...

In this paper, we evaluate query term suggestion in the context of academic professional search. Our overall goal is to support scientists in their information seeking tasks. We set up an interactive search system in which terms are extracted from clicked documents and suggested to the user before every query specification step. We evaluated our method with the iSearch collection of academic in...

Introduction. Use of the Internet for open Web searches is common among university students in academic learning tasks. The tools used by students to find relevant information for online assessment tasks were investigated and their information seeking behaviour was documented to explore the impact on assessment design. Method. A mixed methods approach was followed, using recorded observations o...

Navigating through the ever-changing information space is becoming increasingly difficult. Social navigation support is a technique for guiding users to interesting and relevant information by leveraging the browsing behavior of past users. Effect of social navigation support on users’ information seeking behavior has been studied mostly from conceptual basis or under natural experiments. In th...

Sensation seeking is a core personality trait that declines with age in both men and women, as do also both density and availability of the dopamine D(2/3) receptors in striatum and cortical regions. In contrast, novelty seeking at a given age relates inversely to dopamine receptor availability. The simplest explanation of these findings is an inverted-U-shaped correlation between ratings of se...
