[Objective] This paper proposes a new method to address the issues facing semantic information and relationship representation, aiming to improve the recognition of noun metaphors. [Methods] First, we used the BERT model to replace the word vector, and added position relationship among words for the semantic representation. Then, we utilized the Transformer model to extract features. Finally, we identified the noun metaphors with the help of used neural network classifier. [Results] The proposed model got the highest scores in accuracy (0.900 0), precision (0.896 4), recall (0.885 8), and F1(0.891 0). It covered multiple key points to improve the classification results of noun metaphors. [Limitations] The proposed method could not process the Chinese ancient idioms, as well as rare or dummy vocabularies. [Conclusions] The proposed model could more effectively identify Noun Metaphors than the existing models based on artificial features and deep learnings.
