Entities database

This json file contains the named entities extracted from 3.27 million materials science abstracts.Each document is indexed by it's digital object identifier (DOI) which may be used to find the original article. Each document contains the following entity types: material (MAT), sample descriptor (DSC), symmetry/phase label (SPL), property (PRO), application (APL), synthesis method (SMT), and characterization method (CMT).The named entity recognition was optimized for inorganic materials science.

本 JSON 文件包含了从 327 万篇材料科学摘要中提取的命名实体。每份文档均通过其数字对象标识符（DOI）进行索引，可用于查找原始文章。每份文档包含以下实体类型：材料（MAT）、样本描述符（DSC）、对称/相标签（SPL）、属性（PRO）、应用（APL）、合成方法（SMT）和表征方法（CMT）。命名实体识别针对无机材料科学进行了优化。
