采莓与搜索:随性休闲搜索行为特征研究     

袁红  王奥 《现代情报》2019,39(4):59-68

[目的/意义]随性休闲搜索具有与工作任务情境下以结果为导向的搜索行为不同的规律，探索休闲情境中的搜索行为特征对于信息系统功能的优化，从而为用户日常信息搜索提供更有效的支持具有重要的意义。[方法/过程]论文以采莓模型为基础，采用基于观察实验的日记研究法，招募23位实验参与者进行了为期一周的视频搜索实验，通过文本分析和数据建模，从查询变化、思考、信息/文档、结束4个方面分析了随性休闲搜索行为的特征。[结果/结论]随性休闲搜索中用户需求及其变化带来了查询改变；用户对信息保持着开放选择，从自身情感体验进行搜索评价。随性休闲搜索是一个顺其自然的信息接受和利用过程，也是一项带来快乐体验的休闲活动。  相似文献

Epistemic beliefs in action: Spontaneous reflections about knowledge and knowing during online information searching and their influence on learning     

Lucia Mason  Nicola AriasiAngela Boldrin 《Learning and Instruction》2011,21(1):137-151

In the present study it was investigated whether high school students are spontaneously able to reflect epistemologically during online searching for information about a controversial topic. In addition, we examined whether activating epistemic beliefs is related to individual characteristics, such as prior knowledge of the topic and argumentative reasoning skill; also whether learning from the Web is influenced by epistemic beliefs in action and the ability to detect fallacies in arguments. The participants (N = 64) were students of Grade 13, who were asked to think aloud during navigation. Qualitative and quantitative analyses were performed. Findings reveal that most participants spontaneously activated beliefs about all four dimensions identified in the literature, that is, about the simplicity/complexity, certainty/uncertainty, justification, and source of knowledge, at different levels of sophistication. Most epistemic reflections were about the source of knowledge. Two patterns of contextualized epistemic beliefs emerged and significantly influenced learning from the Web, which was also affected by participants' ability to identify argumentative fallacies.  相似文献   

Can Google Scholar and Mendeley help to assess the scholarly impacts of dissertations?     

Kayvan Kousha  Mike Thelwall 《Journal of Informetrics》2019,13(2):467-484

Dissertations can be the single most important scholarly outputs of junior researchers. Whilst sets of journal articles are often evaluated with the help of citation counts from the Web of Science or Scopus, these do not index dissertations and so their impact is hard to assess. In response, this article introduces a new multistage method to extract Google Scholar citation counts for large collections of dissertations from repositories indexed by Google. The method was used to extract Google Scholar citation counts for 77,884 American doctoral dissertations from 2013 to 2017 via ProQuest, with a precision of over 95%. Some ProQuest dissertations that were dual indexed with other repositories could not be retrieved with ProQuest-specific searches but could be found with Google Scholar searches of the other repositories. The Google Scholar citation counts were then compared with Mendeley reader counts, a known source of scholarly-like impact data. A fifth of the dissertations had at least one citation recorded in Google Scholar and slightly fewer had at least one Mendeley reader. Based on numerical comparisons, the Mendeley reader counts seem to be more useful for impact assessment purposes for dissertations that are less than two years old, whilst Google Scholar citations are more useful for older dissertations, especially in social sciences, arts and humanities. Google Scholar citation counts may reflect a more scholarly type of impact than that of Mendeley reader counts because dissertations attract a substantial minority of their citations from other dissertations. In summary, the new method now makes it possible for research funders, institutions and others to systematically evaluate the impact of dissertations, although additional Google Scholar queries for other online repositories are needed to ensure comprehensive coverage.  相似文献
