收藏资源简介:
该数据集是OpenAlex 2026年5月快照的处理版本,包含处理后的作品记录和衍生引用边表,以及选定的下游文献计量数据集。它专为大规模学术元数据分析、引用网络分析和文献计量研究而设计。主要子集light_openalex_works提供了轻量级的OpenAlex作品记录,以Parquet格式分片存储,包含作品ID、出版年份、类型、主题、作者身份等关键列。其他子集包括扩展的引用边、过滤后的作品类型样本、AI领域作品样本(含机构部门信息)以及包含DI5(五年破坏指数)值的最终AI样本。数据集支持使用Hugging Face datasets库或DuckDB进行加载和查询,适用于文献计量研究、OpenAlex元数据分析、引用网络构建、破坏指数研究等领域。但需要注意的是,数据集受OpenAlex元数据覆盖范围和引用链接的限制,且衍生子集不代表所有学术作品的完整表示。
This dataset is a processed version of the OpenAlex Works snapshot from May 2026, including derived citation-edge tables and selected downstream bibliometric datasets. It is intended for large-scale scholarly metadata analysis, citation-network analysis, and bibliometric research. The main subset, light_openalex_works, contains lightweight OpenAlex Works records stored in Parquet shards, with key columns such as work ID, publication year, type, topics, and authorships. Other subsets include expanded citation edges, filtered work type samples, an AI-domain article/preprint sample enriched with institution-sector information, and a final AI sample with DI5 (five-year disruption index) values. The dataset can be loaded using the Hugging Face datasets library or queried with DuckDB, and it is useful for bibliometric research, OpenAlex metadata analysis, citation-network construction, disruption-index studies, and more. Limitations include dependencies on OpenAlex metadata coverage and citation links, and derived subsets should not be treated as complete representations of all scholarly works.
