OSTI Semantic Thesaurus v1

The OSTI Semantic Thesaurus is a reference for scientific and technical terms and relationships. The term data is used to implement keyword-to-concept mapping in OSTI.GOV searches, where searched term(s) will be mapped to related scientific concepts, allowing the end user to retrieve results related to their search terms and also explore narrower and similar concepts. The OSTI Semantic Thesaurus originally inherited data and structure from the INIS/ETDE Thesaurus (https://www.etde.org/edb/IAEA-INIS-ETDE-01-2013-08.pdf), which was a controlled terminology for indexing information within the subject scopes of the International Nuclear Information System (INIS) and the Energy Technology Data Exchange (ETDE). The data has been expanded upon since that time with the inclusion of scientific concepts from sources like Wikidata, and through manual curation. This dataset is an export from the OSTI Semantic Thesaurus in RDF/SKOS format, which is specifically suited for representation of controlled vocabularies like thesauri. While the full thesaurus includes additional relation types which may be included in future revisions, this export is limited to broader, narrower, and related term relations. Definitions and scope notes are included where available.

OSTI语义词库系科学和技术术语及其关系的参考资源。术语数据被用于实现OSTI.GOV搜索中的关键词至概念的映射，其中搜索到的术语将被映射至相关的科学概念，使得最终用户能够检索与搜索术语相关的结果，并进一步探索更为狭窄和相似的概念。OSTI语义词库最初继承自INIS/ETDE词库（https://www.etde.org/edb/IAEA-INIS-ETDE-01-2013-08.pdf），该词库是国际核信息系统（INIS）和能源技术数据交换（ETDE）主题范围内的信息索引的控制术语。自那时以来，数据得以扩展，纳入了来自如Wikidata等来源的科学概念，并通过人工整理。本数据集是OSTI语义词库以RDF/SKOS格式导出的结果，该格式特别适用于表示如词库等控制词汇。尽管完整的词库包含可能在未来修订版中包含的额外关系类型，但此导出仅限于上位概念、下位概念和相关术语关系。当有可用时，还包括定义和范围注释。
