The construction of social memory is an effective way to realize the continuity of historical context and cultural transmission. In view of the shortcomings of the current research of narrative construction, in this paper the author reconstructs the social memory carried by archives through semantic organization to promote the development and utilization of archives value. Based on the discussion of the logical relationship between social memory and semantic organization, a semantic organization framework of archival information for social memory reconstruction is proposed. Firstly, social memory elements are extracted and their semantic relationships are obtained through thesaurus, description and machine learning. Secondly, social memory ontology is constructed from the perspective of information integration. Finally, the conversion and opening of social memory linked data are proposed from the perspective of shared services, and provides a reference for the panoramic reappearance of social memory and the value development and utilization of archives in the era of big wisdom cloud.
