Entity Recognition for Power Equipment Data Based on Optional Word Vectors and Feature Fusion

Power equipment is an essential part of the power system. Regular inspection and maintenance of power equipment are of great significance. However, the existing entity recognition methods for power equipment data have certain limitations. Therefore, this paper introduces Continuous Bag of Words to optimize Convolutional Neural Network and Long Short-Term Memory network. Meanwhile, Variational Autoencoder is introduced to improve Conditional Generative Adversarial Network. These two methods are combined to form an algorithm that integrates textual data and image information features. On this basis, conditional random field is used for secondary optimization, and an intelligent recognition model is constructed. Its superiority and feasibility are verified by comparison with three traditional models. The results show that the proposed model achieves an accuracy of 96.8%, a recall of 97.6%, an average error of 0.11%, and a loss rate of 0.18%. In practical applications, the model achieves a recall of 97.6% and an Area Under the Curve value of 0.831. When facing different datasets, its average sensitivity reaches 97.6%. Comparative experiments also demonstrate its robustness and generalization ability. All experimental data and results outperform the three comparative models. In conclusion, the proposed model ensures the quality of power equipment data entity recognition and effectively improves recognition efficiency, making an important contribution to the healthy development of the power system in China.
