控制器是将视图上的行为(例如，按下Submit按钮)映射到模型上的操作(例如，检索用户详细信息)。
The Controller maps actions performed on the View (for example, pressing a Submit button) to operations on the Model (for example, retrieving user details).
对于第二种用户行为的检索，目前采取的办法是，根据包括个人基本资料信息，用户的历史行为，用户好友列表来推荐信息。
For the second, user-based analysis, a number of approaches have been taken, including ones based on profile information, user actions, and lists of the user's friends or contacts.
了解具体item和用户空间的规模，对于我们在决定是采用搜索item检索还是采用户行为分析检索有非常大的影响。
The dimensions of the particular item and user space are helpful in deciding whether to use an item-based or user-based approach.
然后，本文讨论了用户在网络数据库信息检索过程中选择行为的行为表现和影响因素。
Then, the dissertation discusses the concrete behavior and effecting factors of users' selection behavior in the process of web database information searching.
人类行为是建立在最小省力原则基础上的，情报检索系统的用户行为中也自始至终贯穿着这一原则。
Human's behavior is based on the principle of minimum power-saving, and the user's behavior in the information retrieval system follows the principle too.
指出了传统信息查寻和情报检索研究只针对个体用户的行为，忽视查寻的社会情景以及用户之间的相互关系的问题。
Traditional information search and retrieval research focused on single-users' activities with less attention on the social context of information search and interaction among users.
因此，如何帮助数据库用户查找到所需要的文献信息就显得尤为重要，而其中探索数据库用户的检索行为是非常重要的研究课题。
Therefore, it is remarkably important that how we can help the database users find the document information they need, among which exploring the retrieval behaviors is an essential research project.
