Abstract

Similarity analysis of power unstructured text is one of the most important tasks in power unstructured data management. This paper studies the feature extraction and similarity analysis of electric power unstructured text. A multi-dimensional fusion feature extraction-based similarity analysis method is proposed to capture the features of unstructured text with more keywords and strong professionalism in electric power. This method improves the MatchPyramid model. In the input layer, word vectors generated by BERT model are used to strengthen the relationship between semantics. In the matching layer, the matching matrix between texts is constructed according to word vectors. In the feature extraction layer, the multi-word feature vectors extracted by BERT model are extracted in a multidimensional text fusion feature vector by means of dense connection. The higher-order feature vector of unstructured text is obtained. The higher-order features of different unstructured texts were input into Pseudo Siamese Network for similarity analysis. This method improves the semantic feature extraction ability and similarity analysis accuracy of unstructured text. Experiments show that compared with the traditional MatchPyramid model, the proposed method improves the feature extraction accuracy of unstructured text by 2.66% and F1 value by 2.99%.
