中文摘要： 探索是人类的天性，几乎所有的搜索都带有不同程度的探索性。随着信息搜寻领域的不断细分，探寻式搜索作为一个新兴的研究焦点引起了广泛关注。结合提问、浏览这两种搜索策略是用户个体探寻信息的主要手段，而人的社会性本质决定了用户之间的社会交互也是探寻式搜索的重要方式。本课题将从社会性软件对用户交互的支持出发，建立社会性搜索策略框架；根据真实提问式的聚类分析得到的搜索主题模拟探索性任务；利用独特的点击流分析方法，揭示用户为应对探索性任务而使用各种搜索策略的行为模式；进而研究用户的认知及情感因素对其行为的影响，以创建探寻式搜索过程模型；最终构建支持人们综合使用社会导向和个体导向策略的探寻式搜索系统原型，并在构建过程中借助用户眼动追踪技术对其进行形成性评价。该研究将完善探寻式搜索领域的搜索社会化理论及用户搜索数据采集分析方法，而且对于在日常搜索中帮助人们解决探索性的信息需求将起到积极指引作用。

英文摘要： Humans are explorers by nature. Almost all searches are exploratory in some way. As a result of the subdivision of the information seeking domain, exploratory search has become a new research focus arousing extensive attention. Individual users explore for information mainly via the combination of querying and browsing strategies, but the social interaction between users can also lend itself to exploratory search because of the fact that humans are social creatures. This research project will firstly create a framework of social search strategies through studying how user interaction is supported by social software. Then we will generate simulative exploratory tasks from the clustering analysis of real-world search queries. A clickstream data analysis will be made on users' behavior in accomplishing exploratory tasks in terms of their search strategies. The effects of cognitive and affective factors on their behavior will be investigated to construct an Exploratory Search Process Model. We will finally build a prototype exploratory search system that supports the integrated use of socially oriented and individual-oriented strategies and conduct a formative evaluation of the prototype in virtue of the eye movement tracking technology. The significance of this research consists in its contribution to the maturing
