基于浏览器日志分析的探索式搜索行为研究

A Study on Exploratory Search Behaviors Based on Browser Log Analysis

为探讨网络用户探索式搜索行为的特点,设定一个提问-应答式搜索任务和两个复杂程度不同的探索式搜索任务,并根据受试者的检索能力分组,在实验环境下,记录受试者的浏览日志。日志分析结果表明,任务类型与搜索能力均对探索式搜索行为产生不同程度的影响。与提问-应答式搜索相比,探索式搜索需要的信息量大,受试者受自身知识背景影响程度高,且任务难度越大,探索结果越多、越分散;检索能力的强弱对受试者探索式搜索行为的影响较小。

To explore the characteristics of web users＇ search behaviors in the exploratory search process, this paper sets one question-answer search task and two different complex exploratory search tasks, divides the participants into two groups according to their retrieval capacity, and records their browser logs in the experiment. The results of log analysis indicate that search tasks and search ability can differently affect users＇ search behaviors in the exploratory search process. Compared to the question-answer search, exploratory search demands more information; participants are highly affected by knowledge background ; the more difficult the task, the more and more dispersed the results of exploration ; the retrieval capacity less affects the search behaviors in the exploratory search process.
