“…The more users were able to focus on results inspection instead of querying and on working with information in documents found instead of result inspection, the better this seemed to be to the process of construction for proceeding in the task [cf. 30, 39, 42]. Also a recent query log study [47] seems to hint at this.…”

“…Thus, the dependent factor used does not represent search effectiveness, but the characteristics of cognitive processing in evaluating search results. Butcher and colleagues [42] studied how pre-service teachers search educational material for classroom instructions using two different interfaces. The three search tasks in the study emulated online, daily instructional planning activities.…”

The paper surveys empirical studies on the relations between information searching and learning, and presents some reflections about learning in a search process based on the findings. First, the meaning of the concepts 'learning' and 'searching' is briefly defined. Learning is conceptualized as changes in one's knowledge structures. Then it is described more in detail how learning occurs in the search process. The point of departure is to focus on tasks that require the restructuring of knowledge structures and to analyse how gradual stabilization of those structures is related to accessing and interacting with information sources. After that, empirical studies on searching and learning are categorized by identifying independent and dependent variables in those studies. In conclusion, some general remarks on the topic are presented.

“…Increased time use is here an indirect proof of increasing knowledge (cf. Butcher et al, 2011). In addition, an expert will count the concepts that have been identified for the question of Task 4 for scoring.…”

“…The results offer insight for understanding how well each tactic observed is supported by each part of the interfaces. Butcher et al (2011) investigate the effectiveness of graphical search tools to support teachers with limited domain knowledge to evaluate the content of educational resources. The aim of the study is to analyze the cognitive processing load and the thinking level during the online search process when using the graphical and keyword search interfaces.…”

Supporting navigation in Wikipedia by information visualization: extended evaluation measures

Purpose -The authors introduce two semantics-based navigation applications that facilitate information-seeking activities in internal link-based web sites in Wikipedia. These applications aim to help users find concepts within a topic and related articles on a given topic quickly and then gain topical knowledge from internal link-based encyclopedia web sites. The paper aims to discuss these issues. Design/methodology/approach -The WNavi s application consists of three information visualization (IV) tools which are a topic network, a hierarchy topic tree and summaries for topics. The WikiMap application consists of a topic network. The goal of the topic network and topic tree tools is to help users to find the major concepts of a topic and identify relationships between these major concepts easily. In addition, in order to locate specific information and enable users to explore and read topic-related articles quickly, the topic tree and summaries for topics tools support users to gain topical knowledge quickly. The authors then apply the k-clique of cohesive indicator to analyze the sub topics of the seed query and find out the best clustering results via the cosine measure. The authors utilize four metrics, which are correctness, time cost, usage behaviors, and satisfaction, to evaluate the three interfaces. These metrics measure both the outputs and outcomes of applications. As a baseline system for evaluation the authors used a traditional Wikipedia interface. For the evaluation, the authors used an experimental user study with 30 participants. Findings -The results indicate that both WikiMap and WNavi s supported users to identify concepts and their relations better compared to the baseline. In topical tasks WNavi s over performed both WikiMap and the baseline system. Although there were no time differences in finding concepts or answering topical questions, the test systems provided users with a greater gain per time unit. The users of WNavi s leaned on the hierarchy tree instead of other tools, whereas WikiMap users used the topic map.Research limitations/implications -The findings have implications for the design of IR support tools in knowledge-intensive web sites that help users to explore topics and concepts. Originality/value -The authors explored to what extent the use of each IV support tool contributed to successful exploration of topics in search tasks. The authors propose extended task-based evaluation measures to understand how each application provides useful context for users to accomplish the tasks and attain the search goals. That is, the authors not only evaluate the output of the search results, e.g. the number of relevant items retrieved, but also the outcome provided by the system for assisting users to attain the search goal. 392JDOC 70,3 groups to collaborate and create long-lasting artifacts that benefit the whole community (Doan et al., 2011).
