| Abstract: | Purpose/significance]With the rapid growth of scientific literature resources, users are surrounded by the ocean of scientific literature, and the future trend of the document knowledge retrieval is to provide users with fast and accurate fine-grained knowledge element services. Method/process]Based on the analysis of the content structure of scientific literature, this paper went gradually and deeply into the scientific literature contents, with a view of constructing a knowledge element ontology model of scientific literature for the knowledge representation, to express fine-grained knowledge points owning holonomic sentence meanings in the content of scientific literature as knowledge elements with a unified structure. Result/conclusion]The paper illustrates the rationality of the model of scientific literature by the means of displaying the content of a scientific literature, but this example only shows knowledge points in the introduction of scientific literature and the knowledge element ontology model needs to be further verified. |
