The fuzzy association degree in semantic data models
This paper presents an expression of the semantic proximity. Based on the concept of the semantic proximity, an evaluated method of the fuzzy association degree is given. It is shown that the method is reasonable and effective. Particularly, by means of the fuzzy association degree, we can discover the connection between a plant acid some ecological environment which will be helpful to the exploitation of rare plants.
