Based on the analysis of the key factors involved in the situation information recommendation, this paper integrates the situation information into the traditional “user-item” recommendation system, and constructs a multi-dimensional and multi-level battlefield situation information recommendation model. Furthermore, the two-dimensional recommendation model is extended to multi-dimensional recommendation model to improve the accuracy of the recommendation system. On the basis of the multi-dimensional recommendation model, the ontology modeling method is used to model the situation information, and the battlefield situation information recommendation method based on ontology similarity is designed. |
