【摘要】：信息搜寻行为研究是用户行为研究的核心领域之一,目前面向“特定用户群体”和“特定信息系统环境”是该领域的研究热点。随着社会化信息系统的兴起与发展,面向社会化信息系统的社会化信息搜寻引起了学术界的重点关注。不同的社会化信息系统环境中,用户的信息搜寻行为不可一概而论。社会化问答平台发展至今,已形成一个庞大的、有价值的、带有社交关系的知识库,越来越多的用户利用社会化问答平台搜寻信息、解决问题。然而爆发式增长的社区内容给用户搜寻信息带来了困难,此外,用户的信息搜寻方式也由单一化向多元化转变,社会化问答平台用户的信息搜寻行为备受关注。目前社会化问答平台用户信息搜寻行为的相关研究,或探讨用户搜寻的内容、问题类型,或基于满意度、可信度对搜寻结果进行评估,而对于“如何搜寻”这一角度多围绕搜寻过程的一个环节或一种策略展开讨论,缺乏全面性和系统性。此外,以往任务对信息搜寻行为的影响研究普遍关注web搜索引擎和专业搜索系统,社会化问答平台这一领域还有待拓展和验证。针对以上问题,本文将用户信息搜寻行为置于任务情境下,着眼于查询行为、浏览行为、选择行为、搜寻路径等完整信息搜寻过程,探究社会化问答平台的用户信息搜寻行为。本文阐释了社会化问答平台的内涵、内容产生与传播机制以及知乎问答平台的内容组织结构,结合信息搜寻行为变量的相关理论基础,构建了社会化问答平台的用户信息搜寻行为变量框架,并通过对任务内涵的解析和任务类型的梳理,构建了任务变量框架。采用实验法,利用Morae录屏软件和调查问卷收集用户行为数据,利用统计学非参数检验方法,结合MoraeManager、Excel和SPSS19.0软件进行数据分析。从查询重构策略的选择、任务对查询重构行为的影响、查询重构策略的转移模式、每种类型任务中浏览行为比较、任务类型对浏览行为的影响、每种类型任务中选择话题、问题、用户的具体方式比较等方面挖掘用户信息搜寻行为特征,并总结了三种搜寻路径模式:“查询/浏览”路径模式、“选择问题/浏览详情/其他”路径模式、“选择话题/浏览详情/其他”路径模式。最后根据研究结果,从优化平台搜索功能、改善平台组织结构、提高平台问答质量三个角度提出面向搜寻过程的服务优化策略。
[Abstract]:The research of information search behavior is one of the core areas of user behavior research. At present, "specific user group" and "specific information system environment" are the focus of research in this field. With the rise and development of socialized information system, the socialized information search for socialized information system has attracted the attention of academic circles. In different social information system environment, user's information search behavior can not be generalized. Up to now, the social question answering platform has formed a huge, valuable, social relationship knowledge base. More and more users use the social question answering platform to search for information and solve problems. However, the exploding community content makes it difficult for users to search for information. In addition, the information search methods of users are also changed from single to diversified, and the information search behavior of users in social Q & A platform has attracted much attention. The current research on user information search behavior in social Q & A platform, or explore the content of user search, the type of question, or based on satisfaction, credibility to evaluate the search results, However, there is a lack of comprehensiveness and systematicness in the discussion of "how to search" around a link or a strategy in the search process. In addition, research on the impact of tasks on information search behavior has focused on the web search engine and professional search system. The social question answering platform needs to be expanded and verified. Aiming at the above problems, this paper puts the user information search behavior under the task situation, focusing on the query behavior, browsing behavior, selecting behavior, searching path and other complete information search process, and explores the user information search behavior in the social question answering platform. This paper explains the connotation of the social Q & A platform, the content generation and dissemination mechanism, the content organization structure of the Question-answering platform, and the relevant theoretical basis of information search behavior variables. This paper constructs the framework of user information search behavior variables in the social question and answer platform, and constructs the task variable framework by analyzing the connotation of tasks and combing the types of tasks. The experimental method was used to collect user behavior data using Morae screen recording software and questionnaire. The data were analyzed by using statistical non-parametric test method and combining with Morae Manager Excel and SPSS 19.0 software. From the selection of query refactoring strategy, the influence of task on query refactoring behavior, the transfer mode of query refactoring strategy, the comparison of browsing behavior in each type of task, the influence of task type on browsing behavior, the topic selection in each type of task. In this paper, the characteristics of user information search behavior are explored in terms of problem, user's specific way comparison, and three search path modes are summarized: "query / browse" path mode, "select problem / browse details / other" path mode, Select topic / browse details / other path mode. Finally, according to the research results, the search process oriented service optimization strategy is put forward from three aspects: optimizing the platform search function, improving the platform organization structure and improving the platform question and answer quality.
