| Abstract: |
With the rapid development of mobile Internet，mobile search becomes increasingly more popular. There are critical needs for developing theoretical and practical understanding of this relatively new search phenomenon. As an important aspect of users’behaviors，mobile users search strategies play important roles in understanding users’ search intentions and their search behavior characteristics. We intend to study college students’ behaviors through in depth analyzing their information needs within a search session context，and combine it with examining the recorded search logs，which contain detailed user’s behaviors on querying，selecting，and reviewing in the search sessions. The particular participants we recruited in this study were all college students，who are one of the main user groups for mobile searches. We examined the relationship between the search session and query，characterized the features of mobile search sessions，discussed the factors of these features，and compared the behaviors of our participants to those of the populations in existing studies in the literature.
Our research examined the participants in their real life search environment. 30 college students were recruited to conduct this uncontrolled experiment for two weeks. Their phones were installed AWARE logging software to collect the data，and the participants needed to complete structured diary every day to describe one mobile search with deepest impression. The diary recorded the mobile searchs information needs，search motivation，search context，search experience，etc. After the experiment，we conducted an interview to ask the participants to explain the reasons of characteristics in the mobile search process. We analyzed the relevant data in questionnaire，the search logs，and the diary，and combined with the text content of the interview to achieve quantitative analysis and qualitative analysis.
Our results show that the participants searched for information with different languages in mobile environment. Different from other users’ more diverse information needs，college students focused on several particular topics. The numbers of queries and search sessions observed in this experiment were higher than what are reported in the literature，which might show that users with higher information literacy would search more frequently. As mobile searches become easier to operate，college students could satisfy their information needs through shorter queries and search sessions. At the same time，they performed more complex search tasks on the mobile phone through multiple strategies. We also found that the mobile applications they used were more diverse in a search session，reflecting their different search strategies. In addition，mobile search would lead to other follow up activities such as making a purchase，navigating，sharing the search results，etc.
Studying the mobile search strategy will help to understand the features of users search behaviors，and it can enable mobile service providers to serve better to users search habits and information needs. 11 figs. 5 tabs. 27 refs. |
| 中文摘要: |
| 在移动互联网迅速发展的背景下,移动搜索日趋普遍,搜索策略成为用户行为研究的一个重要方面。现有用户搜索策略研究包含查询式和搜索会话的统计分析,以及结合用户的信息需求、搜索情境来分析原因。本研究通过非受控实验的方式,对大学生用户在移动环境下的查询式构造、搜索会话中的查询式及搜索会话的其他特征进行分析。研究发现:在移动环境下大学生用户习惯使用多种语言组配进行搜索；搜索信息的主题类型存在聚焦现象；移动搜索更加便捷,大学生用户通过更短的查询式、搜索会话便可满足其信息需求；大学生用户会通过多种策略,在手机上执行较为复杂的搜索任务；其搜索活动会引发其他后续活动。研究大学生用户在移动环境下的搜索策略,可了解其搜索行为特征,有助于搜索引擎服务商提供更符合其搜索习惯的服务,更好地满足其信息需求,提高搜索效率。图11。表5。参考文献27。 |
