Probability Model in Semantic Analysis of Complicated Target Image Based on Ontology

We integrate the advantage of semantic depiction using ontology and the advantage of complicated targets image modeling using Bag Of Words model,complicated targets semantic reasoning model is introduced using the ontology concept as a random variable in Bag Of Words model.This model can map the ontology concept to the image.Consequently,the semantic conclusion of the image is obtained by reasoning the mapped ontology concept in the semantic net.The experimental result shows that the model is validate.
