Subject Exploration in the Field of Library and Information from the Perspective of the Theory of Social Cognition

: In the theory of social cognitive hierarchy, topic detection is an important part of research. It can provide readers with more information and enable them to obtain a better cognitive experience. The subject detection tasks in the field of library and information in our country are constantly developing, and great achievements have been made. In order to improve the efficiency of subject detection in the field of library and information, this paper proposes a subject detection method under the perspective of social cognitive level. This article mainly uses statistical analysis and survey methods to analyze the key factors of subject detection. The experimental results show that the reasonableness score of the four factors proposed in this paper is about 15 points on average. This shows that the factors studied in this article are closely related to topic detection.
