中文摘要：	基于任务的研究一直是情报学领域的热点。任务类型和任务属性一直被视为影响用户信息搜索行为的重要因素。用户的信息搜索行为受到其信息需求的驱使，而搜索满意度则关注了信息需求的满足程度。图像搜索行为作为信息搜索行为的重要分支，其受关注度远不如文本信息搜索行为，特别在国内，鲜有关于图像搜索满意度的研究。因此本研究从不同类型和属性的任务出发，研究网络用户图像搜索行为的交互特征以及用户满意度，并试图解释满意度与任务类型和属性之间的关系，以及尝试揭示图像搜索行为特征能否以及如何预测用户的满意度。 本研究采用实验法，收集的数据有三类：用户对模拟仿真任务的主观评估数据（任务难度、主题熟悉度、自信度）、图像搜索行为数据和满意度评估数据。通过实验前测问卷收集模拟仿真任务的主观评估数据，使用屏幕录像软件收集用户的图像搜索行为数据，通过实验后测问卷收集用户的满意度评估数据。 在图像搜索行为分析方面，本研究参考关键行为定义表识别了三种行为，并研究了用户搜索图像时的路径选择、查询特征和行为模式。在行为模式的划分中，本研究将用户分为随意型、执着型和调整型。 通过描述性统计数据和SPSS统计检验，本文得出以下结论：用户偏向于使用百度图片，且对初次搜索入口较为依赖。用户倾向于直接使用主题词搜索，查询构造的方式主要是增加限制，其次是对格式和形式进行调整。用户的图像搜索行为更多体现为积极、追随、低水平和低层次的交互。.图像搜索行为受到用户性别的显著影响，男生比女生更随意，其他特征对行为模式影响不大。任务的类型会影响用户的图像搜索行为，越特指的任务用户搜索行为越随意，越主观的任务用户越积极调整自己的行为。 此外，用户的图像搜索行为模式和满意度之间关系密切，且对满意度具有预测作用。任务类型和属性是影响用户满意度的核心因素。 任务类型会显著影响图像搜索满意度，其中，不同任务的满意度高低方面，A组—指定的>B组—可命名的>D组—主观的>C组—抽象的。任务难度感知越高，满意度越低。对任务主题越熟悉，满意度越高。实验者对完成任务的自信度越高，满意度越高。 本研究丰富了信息搜索行为和满意度的理论成果，并对图像搜索工具或系统的设计和改善提供了依据和启发，具有理论和实践意义。
英文摘要：	Task-based information retrieval research has always been a hot topic in the field of information science. Task types and task attributes have been regarded as an important factor affecting user search behavior. The user's information search behavior is driven by its information needs, while search satisfaction is concerned about the degree of information needs to meet. Image searching behavior as an important branch of information searching behavior, it has received much less attention compared to text information search behavior, especially in China. Therefore, this study starts from the different types and attributes of the task, to study web user’s image searching behavior and the interactive features and their satisfaction, and try to explain the satisfaction and task types and attributes of the relationship between, and try to reveal the characteristics of image searching behavior and how to predict user satisfaction. In this study, three types of data were collected: the subjective evaluation data (task difficulty, subject familiarity, self-confidence), image search behavior data and satisfaction evaluation data of the simulation task. The subjective evaluation data of the simulation task was collected by the pre-test questionnaire, and the user's image search behavior data collected by the screen recording software. The user's satisfaction evaluation data was collected by the post-test questionnaire. In the aspect of image searching behavior analysis, this study identifies three behaviors with reference to the key behavior definition table, and the path selection, query characteristics and behavior patterns when users searching for images were analyzed. In the division of behavior patterns, this study divides users into random, persistent, and adjusted. Through descriptive statistics and SPSS statistical tests, this paper draws the following conclusions: users prefer to use Baidu Image, and they are dependent on the initial search portal. Users tend to use keyword search directly, the main way of query constructs is to increase the restrictions, followed by the format and form of adjustment. The user's image search behavior is positive, following, low-level and low-level of interaction. Image search behavior is significantly influenced by the gender of the user, and boys are more casual than girls. Other characteristics have little effect on behavior patterns. The type of task will affect the user's image search behavior. In specific tasks , users’ search behavior tends to be more casual, while in more subjective tasks users are more likely to actively adjust their behavior. The relationship between user's image search behavior pattern and satisfaction is closely related and that pattern has a predictive effect on satisfaction. Task type and attribute are the core factors that affect customer satisfaction. Task type will significantly affect the image search satisfaction, which in the satisfaction of different tasks, A group - specific > B group - namable> D group - subjective> group C - abstract. The higher the difficulty of the task, the lower the satisfaction. The more familiar with the theme of the task, the higher the satisfaction. The higher the self-confidence of the experimenter to complete the task, the higher the satisfaction. This study enriches the theoretical results of information search behavior and satisfaction, and provides the basis and inspiration for the design and improvement of image search tool or system, which has theoretical and practical significance.
