探索式搜寻意图对搜寻策略选择的影响机制研究

目的/意义]研究旨在回答不同探索式搜寻意图的用户如何表达信息需求,不同的需求表达倾向于采用哪种搜寻策略,以及该选择机制如何受用户预期绩效的影响。方法/过程]通过理论研究探索用户搜寻意图的复杂性和搜寻策略的多元化,结合用户需求表达和用户预期绩效的分析,建立用户探索式搜寻意图对搜寻策略选择的影响机制的理论研究框架,通过情景模拟问卷获取搜寻行为数据,以揭示无向信息收集、有向信息收集、知识获取、建议咨询、社会联系5种探索式搜寻意图在选择综合搜索引擎、专业搜索引擎、个人空间SMQA、问答平台提问和短视频网站浏览策略时的策略偏好及其成因。结果/结论]研究表明,探索式搜寻意图需求表达的差异受搜寻目标的性质和用户认知能力的影响;不同需求表达的搜寻策略选择具有显著差异;预期绩效的调节作用促进了探索式搜寻策略选择的多元化和策略转换。

Research on the Influence Mechanism of Exploratory Seeking Intention on Seeking Strategy Selection

Purpose/significance]The purpose of this study is to answer how users with different exploratory seeking intention express their information needs,which seeking strategy is preferred by different expressions of needs,and how this selection mechanism is affected by users'expected performance.Method/process]This paper explored the complexity of users'seeking intention and the diversification of seeking strategies through theoretical research,and established a theoretical framework on the influence mechanism of users'exploratory seeking intention on seeking strategy selection combined with the analysis of users'demand expression and expected performance,then collected seeking behavior data by scenario simulation questionnaire to reveal the preference and its causes of five exploratory seeking intentions(undirected information collection,directed information collection,knowledge acquisition,suggestions for consultation,and social connection)in choosing seeking strategies(comprehensive search engine,professional search engine,personal cyberspace SMQA,Q&A platform enquiring,and short video website browsing).Result/conclusion]The difference of the demand expression of exploratory seeking intention is caused by the nature of seeking objectives and users'cognitive ability.There are significant differences in the choice of seeking strategies for different demand expression.The regulatory effect of expected performance promotes the diversification and strategy transformation of exploratory seeking strategy selection.
