摘要

为提升水产疾病防治中复杂与多层次因果关系抽取的准确性，引入一种双向焦点增强机制（bidirectional focus enhancement mechanism，BFM），提出RoBFM模型（RoBERTa-wwm-ext-large bidirectional focus enhancement mechanism）。该模型结合预训练语言模型RoBERTa-wwm-ext-large生成高质量词嵌入，并利用双向长短时记忆网络（bi-directional long short-term memory，BiLSTM）增强长距离依赖性建模。RoBFM的核心是通过BFM机制的前后向权重分配，强制解耦并聚焦因果语义角色。为全面评估模型性能，在公开数据集DuIE和自建的领域专用数据集DLOU-CRE上开展了基线对比试验与消融实验。试验结果显示，该模型在公开数据集DuIE和自建的领域专用数据集DLOU-CRE上的

值等指标均优于现有模型。尤其在DLOU-CRE数据集上，

值达到了68.23%。结果表明，该方法用于水产病害防治因果关系抽取中具有更好的效果。

Abstract

To enhance the accuracy of extracting complex，multi-level causal relationships in aquatic disease control，this study introduces a bidirectional focus enhancement mechanism （BFM） and proposes the RoBFM model （RoBERTa-wwm-ext-large integrated with bidirectional focus enhancement mechanism）.The model integrates the RoBERTa-wwm-ext-large pre-trained language model to generate high-quality word embeddings and leverages Bi-directional long short-term memory （BiLSTM） networks to strengthen long-distance dependency modeling.The core innovation of RoBFM resides in the BFM mechanism，which employs forward and backward weight allocation to explicitly decouple and focus on causal semantic roles.To systematically evaluate the model’s performance，this paper conducts baseline comparison and ablation experiments on the public dataset DuIE and the self-constructed，domain-specific dataset DLOU-CRE.Experimental results demonstrate that the proposed model surpasses existing baselines in terms of

score and other metrics on both datasets.Notably，the model achieves an

score of 68.23% on the DLOU-CRE dataset，demonstrating that the proposed method is more effective for causal relationship extraction in the prevention and control of aquatic animal diseases.
