Construction of Visualization Model of Maternal Health Care Based on Domain Ontology

In order to effectively analyze and utilize a large number of maternal health care diagnosis and treatment guidelines, electronic medical records and clinical data, and promote the sharing and reuse of knowledge and experience in the field of maternal health care, the project uses ontology technology to carry out semi-automatic ontology construction through analysis and reference seven steps and knowledge extraction technology, The ontology knowledge base model of pregnancy and childbirth domain is constructed. In order to further show the domain ontology of pregnancy and childbirth, through the visual analysis of the domain ontology of pregnancy and childbirth, using data visualization technology and domain oriented strategy, this paper constructs the domain ontology visualization model of pregnancy and childbirth.
