摘要:

区分匹配的命名实体对或识别实体的规范形式是文本挖掘任务中的关键。文本挖掘中更精确的命名实体规范化将有益于其他后续的文本分析应用。采用一种新的边权值更新神经网络建立命名实体规范化模型。我们提出的模型在四个不同的数据集上进行测试时,取得了最先进的结果。接下来,我们在NCBI疾病、BC5CDR疾病和BC5CDR化学数据库上验证了我们的模型的性能,这些数据库是生物信息学领域中广泛使用的命名实体标准化数据集。我们还使用我们自己的金融命名实体规范化数据集测试了我们的模型,以验证更一般应用程序的有效性。使用构造的数据集,我们区分命名实体对。我们的模型在各种评估指标方面实现了最高的命名实体规范化性能。

英文摘要:

Discriminating the matched named entity pairs or identifying the entities' canonical forms are critical in text mining tasks. More precise named entity normalization in text mining will benefit other subsequent text analytic applications. We built the named entity normalization model with a novel Edge Weight Updating Neural Network. Our proposed model when tested on four different datasets achieved state-of-the-art results. We, next, verify our model's performance on NCBI Disease, BC5CDR Disease, and BC5CDR Chemical databases, which are widely used named entity normalization datasets in the bioinformatics field. We also tested our model with our own financial named entity normalization dataset to validate the efficacy for more general applications. Using the constructed dataset, we differentiate named entity pairs. Our model achieved the highest named entity normalization performances in terms of various evaluation metrics.
