Simulation Model of Semantic Information Retrieval Based on Differentiation Fusion

A semantic information retrieval algorithm is proposed based on differentiation fusion, the model design and simulation are realized. The semantic ontology model is constructed, the correlation dimension difference characteristic is extracted, fusion model difference semantic information features take top-down method, the difference of semantic information is obtained, semantic information retrieval ontology model is obtained in the feature space, the semantic feature of information is computed, different text component elements of classification processing is fused, the stratified differentiation characteristics of fusion, achieve improved semantic information retrieval algorithm.
