Biography, a historical genre dating back to antiquity, is a scholarly resource in history and prosopography(Shimizu et al., 2020). It records the lives of individuals and serves as a witness to social customs and historical scenes. However, most biographies follow the traditional form of non-structured text and cannot reveal the semantic features of biographers(Hyvönen et al., 2019), which has hindered information mining and retrieval. Semantic Web technologies provide a solution through deep semantic descriptions. However, few studies explore the semantic modeling of biography. Given this, we constructed a biographical ontology based on existing ontology and terms extracted from an autobiography. On this basis, semantic applications, such as semantic retrieval, annotation, and reasoning, can be explored.
