Information on-demand distribution method and system

The invention discloses an information on-demand distribution method and system, and the method comprises the following steps: (1) receiving superior literature and telegram information to obtain an action task, and obtaining information; (2) extracting features including commander features, action task features and intelligence features; (3) error processing and model optimization; and (4) sorting and outputting the intelligence according to the interestingness according to the optimized model. Tasks and intelligence texts are preprocessed through an improved linear discriminant analysis method, the tasks and intelligence data are encoded by adopting a sparse edge noise reduction automatic encoder, and the blank part of a matrix is removed by adopting a matrix decomposition algorithm for dimensionality reduction, so that the accuracy of a training model is effectively improved; and meanwhile, the accuracy of information on-demand distribution is improved, and the commanding efficiency of commanders is improv
