社交网站的兴起给人们提供了实现社会化搜索的大好机遇,但在什么情况下人们更愿意使用社会化搜索或是传统搜索还不得而知。文章探讨了在良构和非良构两种不同任务问题的情境下用户的选择策略,并进一步分析了用户利用两种搜索方式所带来的信息收益和认知收益的差异及信息分享意愿的差异。结果显示,对于良构问题用户更倾向于采用传统的搜索引擎;对于非良构问题用户倾向于使用社会化搜索,或是两种搜索相结合的策略。 The rise of social networking sites offers great opportunities for social search, but it is unclear under what circumstances people prefer to use social search or traditional search. This paper discusses the user’s selection strategy in the situation of well-structured and non-well-structured two different tasks and further analyzes the difference between the information and cognitive benefits that the users use two search methods and the willingness of information sharing difference. The results show that users are more likely to adopt traditional search engines for well-structured issues, and social search for unstructured users or a combination of two search strategies.
