In this paper,the diary method is used to collect the search task examples with learning characteristics from 16 national economic industries in real work context,and the search task is characterized in combination with the task conceptual framework to construct a multidimensional task library for"search-as-learning"research,and further analyze the attributes and characteristics of search tasks in real work context.Task-related characteristics,cognitive changes and behaviors of participants,and relationships of them were discussed,and the relationships among the three groups of variables were compared according to the participants'educational level,cognitive level of completing tasks,and time pressure of the participants when completing the task.The results showed that the participants'familiarity and interest in the task,and the amount of required information types significantly affected the cognitive changes,and the influence of the characteristics of the task performers on the cognitive changes and behaviors was significantly different in differ-ent contexts.The task library developed in this study can serve as a public research resource for"search as learning"research,as well as an evaluation set for evaluating the complex task processing ability of AIGC technology,providing a basis for developing efficient information systems for real-world work task contexts.
