信息搜寻可以视为一种问题解决活动,了解用户在信息搜寻过程中信息问题空间的构建过程,从认知机制角度刻画用户复杂且模糊的信息需求,以及这些需求逐步递进的过程,有利于支持用户更好地解决信息问题,为相应的系统设计和信息服务优化提供参考。本文在系统梳理信息问题解决和信息需求表达相关理论的基础上,提出信息问题空间的概念;通过“目的-手段”形式呈现信息问题的主题分面,以表征用户信息问题空间内部结构;结合仿真搜索实验结果,阐明群体用户信息问题空间的表征方式;进一步讨论如何优化系统以辅助用户构建信息问题空间,解决各类信息问题。结果表明,信息问题空间能够表征用户信息搜索中的动态认知过程。未来研究需关注用户信息问题空间的表征方式（含可视化方式）和搜索系统对用户构建信息问题空间的交互支持功能。 相似文献

在风险社会中,科技的发展不仅是衡量现代性的核心要素,同时也是催生不确定性的重要原因。社交媒体的发展很大程度改变了风险传播的景观,使得风险认知和媒介信息之间的关系更加复杂。本研究采用问卷调查法对临近核电站建设区域社交媒体用户进行调查,旨在探讨社交媒体环境下的信息对受众风险信息搜索行为的影响。本研究采用结构方程模型的分析方法,从社会认知理论出发考察社交媒体环境中信息的质量对受众反应的作用过程。结果显示信息质量可以通过影响用户的风险认知、风险知识水平和自我效能三个变量影响其风险信息搜索行为,从而证明社交媒体所构建的信息环境会显著作用于人们对于风险的认知和行为反应。本研究的发现期待可以为风险传播中的有效公众沟通策略以及线上风险信息管理提供参考。 相似文献

作为学习科学持续关注的一个话题,学习投入的研究范畴越发广泛。“搜索即学习”让人们同时对交互式信息检索与学习活动产生了别样的认识。探究学习投入的影响因素有助于提升信息搜索用户的认知灵活性与知识迁移、应用和创新能力,并为优化支持学习目标的信息检索系统的功能设计提供借鉴。本研究将信息搜索用户的学习投入划分为行为投入、认知投入和情感投入3个维度,运用信息检索实验探究学习风格与认知弹性对这3个维度的影响作用。数据分析与处理手段包括搜索日志分析、内容分析、自我报告以及方差分析、卡方检验。本研究发现,第一,学习风格对信息搜索用户的学习认知投入存在显著差异,而对学习行为投入、学习情感投入未产生影响;第二,认知弹性可以影响信息搜索用户的学习行为投入,并在用户的学习情感投入表现上有所不同,而对学习认知投入未产生显著影响;第三,学习风格与认知弹性仅单独作用于信息搜索用户学习投入的3个维度,并未对其产生交互效应。 相似文献

The Information Revolution has resulted in dynamic changes in information dissemination services. It is difficult for most people to understand the dynamic causes, processes, and the effects of these changes on the information world. Gender as a variable has been identified in some studies as a possible influencing variable in information seeking research. Some social psychology depicts physical, mental and social differences between men and women in society. Gender as a variable may be useful for better understanding the cognitive and social background of human information processing and may have important implications for information dissemination services and systems. Hence, it is pertinent to explore the gender-specific differences in information seeking behavior of university students so as to better assist them in their information search processes.The objective of this study was to determine whether gender as a variable is related to the information seeking behavior of university students. Data were collected from 600 university students studying different disciplines (arts, science and commerce) from three state-aided universities in West Bengal, India. Data tools included a General Information Schedule and an Information Seeking Behavior Inventory. Significant differences were noted in most of the domains of information seeking behavior with respect to gender (male and female). Females scored high on all the domains of information search except in diversity in search where the males were found to be high. The findings may have implications for research and practice in psychology, especially in the subfields of educational institutions, library science, cognitive development, and training and performance appraisal. 相似文献

Researchers have increasingly paid attention to the personal and emotional growth of youth. However, little research has examined how exactly young people use or seek information for their personal development and growth. The primary goal of this study, therefore, was to explore the students' use of “information seeking” to cope with their day-to-day personal stressors and problems. The sample consisted of 641 children in fifth- and sixth-grade classrooms from an urban public elementary school in Taiwan. Data were collected through semistructured, open-ended surveys. Both quantitative and qualitative methods were employed to analyze the data. This study found that in coping with daily-life problems, nearly two-thirds of the participating children would seek information; that sixth graders were more likely to do so; and that gender did not make information seeking more (or less) probable in this coping context. Findings also revealed some major reasons for children's information seeking in this coping context, for example, to solve problems, to escape, and to find a transition. Finally, five major different information seeking behaviors related to coping emerged from the findings: information seeking for problem solving, information seeking to escape, information seeking for a transition, information seeking to change mood, and information avoidance, which can be used as a platform to develop an explanatory and possibly predictive framework for future studies. 相似文献

The information needs of scientists in English-speaking countries have been studied and reported in the library literature. However, few studies exist on the information-seeking patterns of scientists in developing countries, and no study has examined the information needs of medical scientists in developing Asian countries. This study investigated the information needs of academic medical scientists at Chulalongkorn University in Bangkok, Thailand. The results indicate that medical scientists have three types of information needs: identifying up-to-date information, obtaining relevant studies and data, and developing research topics. Thai scientists' information-seeking behavior was different from that of scientists in developed countries. The study shows a high use of libraries as information providers; Thai medical scientists rely heavily on information from abroad. 相似文献

学术文本词汇功能识别--基于标题生成策略和注意力机制的问题方法抽取 总被引：1，自引：0，他引：1
学术文本词汇功能识别的目的是实现学术文本中表征问题、方法和对象等词汇的抽取。针对传统识别方法中训练难以获取所导致的识别准确率低、召回率有限和泛化能力差等问题,本研究提出了一种基于深度学习和标题生成策略的学术文本词汇功能识别方法,将任务形式由信息抽取转化为特定形式的标题生成问题。本研究采用构建seq2seq模型和引入注意力机制的方式捕获词汇多层语义信息,最终实现学术文本中问题和方法指代词的生成和获取。实验结果表明,通过应用深度学习方法和标题生成策略,本研究提出的模型能够从摘要中有效识别学术文献的主要研究问题和主要研究方法,并较已有方法在识别效果上有明显提升。 相似文献

This study uses in-depth qualitative interviews to explore the information seeking behavior of 25 mature undergraduates at one Canadian university. It explores the complex interweaving of these students’ everyday and academic information needs in light of Reijo Savolainen’s framework for the study of everyday life information seeking. Findings include the role of social and cultural capital in these students’ information seeking, the diverse ways that everyday and academic contexts inform one another, and the importance of not separating the everyday from other life situations in studies of individuals’ information behaviors. 相似文献
