Named Entity Recognition (NER) is vital in natural language processing for the analysis of news texts, as it accurately identifies entities such as locations, persons, and organizations, which is crucial for applications like news summarization and event tracking. However, NER in the news domain faces challenges due to insufficient annotated data, complex entity structures, and strong context dependencies. To address these issues, we propose a new Chinese-named entity recognition method that integrates transfer learning with word embeddings. Our approach leverages the ERNIE pre-trained model for transfer learning and obtaining general language representations and incorporates the Soft-lexicon word embedding technique to handle varied entity structures. This dual-strategy enhances the model’s understanding of context and boosts its ability to process complex texts. Experimental results show that our method achieves an F1 score of 94.72% on a news dataset, surpassing baseline methods by 3%–4%, thereby confirming its effectiveness for Chinese-named entity recognition in the news domain.
Communication radiation source individual identification technology is an essential technique in electronic reconnaissance and a crucial link in electronic warfare support measures. Nevertheless, when the sample set encounters complex circumstances, such as class imbalance or a small sample, the classification network model, driven by big data, disrupts the symmetry between the recognition effect and the quantity of the datasets, leading to suboptimal recognition performance. Thus, it is requisite to optimize the existing models and algorithms to better propose more representative fingerprint features. This paper references the speech signal recognition model multivariate long short-term memory–fully convolutional network (MLSTM-FCN), and ameliorates the recognition algorithm and training strategy for the two scenarios of class imbalance and a small sample. It puts forward a communication radiation source individual identification method based on MLSTM-FCN incremental random feature concatenation and a communication radiation source individual identification method based on meta-learning. Proceeding from improving the class imbalance issue among features and small-sample learning, the experimental results under various signal-to-noise ratios demonstrate that the proposed methods have superior recognition effects and higher accuracy.
