Research On The Relationship Between Task Type, Task Attribute And Web Users’ Image Searching Behavior

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.
