Embodiment Construction
[0038] Below in conjunction with accompanying drawing, further describe the present invention through embodiment, but do not limit the scope of the present invention in any way.
[0039] The present invention provides a text multi-label classification method based on semantic unit information, which improves the sequence-to-sequence model based on the attention mechanism as the baseline model, improves the content that the attention mechanism focuses on, and improves the attention mechanism at the source Represents and improves the contribution of attention-based sequence-to-sequence models in text multi-label classification.
[0040] The baseline model adopted by the model SU4MLC proposed by the present invention is the sequence-to-sequence model of the cyclic neural network based on the attention mechanism, and the cyclic neural network adopts the LSTM. figure 1 It is a schematic flow chart of the method of the present invention. The specific implementation steps are as fol...
