CORD-19 Diachronic Concept Embeddings

Medical concept embeddings trained on monthly releases of the CORD-19 dataset, for analysis of diachronic change.

This resource includes:

Concept embeddings, trained using the JET toolkit on the set of articles added to CORD-19 in each month of March 2020 - October 2020.  Concepts are SNOMED CT codes.

Nearest neighborhood-based analysis results of the concept embeddings, stored as a SQLite database.

本数据集为基于CORD-19数据集每月更新版本训练得到的医学概念嵌入，用于历时变化分析。

本资源包含以下内容：

概念嵌入：使用JET工具包（JET toolkit），针对2020年3月至2020年10月每月新增至CORD-19数据集的文章集训练所得，其中概念均为医学系统命名法-临床术语（SNOMED CT）编码。
基于最近邻域的概念嵌入分析结果，以SQLite数据库格式存储。
