目的针对大数据环境下跨数据源查询面临的中药实体呈现多视图,且中药实体在各数据源中表现出属性不完整、多模态、差异性等问题,提出面向多源数据的中药实体统一视图的构建策略。方法基于实体属性间的相互关系,构建实体多视图融合整体架构,并对实体和属性等关键元素进行抽象化表示;以用户需求为约束提出基于词向量的相关度计算方法,采用Skip-gram模型训练出表征实体属性的词向量;提出基于欧氏距离和Jaccard系数的相关度算法,并以此为依据进行实体融合。结果共训练完成属性词向量6116个,其中有效词向量230个,以400对不同源中药实体作为测试集,分别采用AFCDS、FF和WVCC方法进行实体融合实验,其融合...

Objective To propose a construction strategy of unified view of TCM entities for multi-source data targeting the fact that TCM entities are faced with multi-data query with multiple views in the big data environment, and that TCM entities exhibit incomplete attributes, multi-modality, and differences in each data source. Methods Based on the interrelationship between entity attributes, an entity multi-view fusion overall architecture was constructed, and abstract representations of key elements such as entities and attributes were carried out. A word vector-based correlation calculation method...
