Improved semantic similarity calculating model and its application
Zhaodan Wang · Journal of Jilin University · 2009
In the semantic searching,the semantic similarity calculation model is crucial to ensure the searching results being all-sided and exact.A new semantic similarity calculation model,PHSS,was proposed based on improving the traditional models.Both the hierarchy and the property restrictions of the concepts were taken into consideration in this new model.The semantic distance between two concepts was described more accurately.Based on this model,a semantic search system,CDPPIRS,for preventing and curing plant disease and insect pests of corn was also constructed.This system can carry out semantic reasoning based on query information and the repository,and provide accurate bibliographies to the users according to their different kinds of enquiries.This system satisfies the enquiries of different level agricultural professionals.Experiment results in CDPPIRS show that the PHSS model is better than traditional models.
