Chinese Clinical Named Entity Recognition with ALBERT and MHA Mechanism
Traditional clinical named entity recognition methods fail to balance the effectiveness of feature extraction of unstructured text and the complexity of neural network models. We propose a model based on ALBERT and a multihead attention (MHA) mechanism to solve this problem.

Chinese Medical Entity Recognition Model Based on Character and Word Vector Fusion
The medical information carried in electronic medical records has high clinical research value, and medical named entity recognition is the key to extracting valuable information from large‐scale medical texts. At present, most of the studies on Chinese medical named entity recognition are based on character vector model or word vector model.

目的探讨胃癌根治性手术前后TM4SF1(跨膜4超家族成员1)水平及病理特征变化。方法选取天津市宁河区医院2016年6月到2019年6月共收治的80例胃癌患者进行回顾性分析,所有患者均行胃癌根治术,分析胃癌患者根治术前胃癌组织及邻近非胃癌组织中TM4SF1表达,胃癌患者根治术后胃粘膜中TM4SF1水平表达与胃癌根治术前TM4SF1表达水平对比,并对比所有患者胃癌根治术前和手术1年后的临床病理特征。结果在同一切段中,TM4SF1在GC组织中呈阴性表达,在相邻非癌组织中呈阳性表达。在我们的患者队列中 ...
