NAL Agricultural Thesaurus and Glossary

The NAL Agricultural Thesaurus (NALT) was first released by the National Agricultural Library in 2002, with in-depth coverage of agriculture, biology, and related disciplines. It contains over 135,000 terms, including 63,000 cross references, and is arranged into 17 subject categories which are used to browse the Thesaurus in a specific discipline or subject area. NALT is updated annually each January. The subject scope of agriculture is broadly defined in the thesaurus, and includes terminology in the supporting biological, physical, and social sciences. Biological nomenclature comprises a majority of the terms in the thesaurus and is located in the "Taxonomic Classification of Organisms" Subject Category. Political geography is mainly described at the country level. Published since 2007, the Glossary is a collection of definitions of agricultural terms developed in conjunction with the creation of the NAL Agricultural Thesaurus. The 2018 edition of the glossary contains 5,618 terms ranging across agriculture and its many ancillary subjects. Most definitions were composed by the NAL Thesaurus Staff. Those definitions taken from government sources are indicated in the "Definition Source" field and are included in the bibliography. In 2010, the thesaurus was made available as Linked Open Data. Linked Open Data translates information into a form both readable and understandable by computers. This translation makes it possible for different information resources, such as Web pages, datasets and research articles, to be interconnected, creating meaningful relationships that make it easier to locate related content. In May 2007, Spanish language versions of its NAL Agricultural Thesaurus (NALT) and Glossary of Agricultural Terms were published under the Spanish language names "Tesauro Agrícola" and "Glosario". The Thesaurus and Glossary are produced cooperatively by the USDA National Agricultural Library and the Inter-American Institute for Cooperation on Agriculture (IICA), as well as other Latin American agricultural institutions belonging to the Agriculture Information and Documentation Service of the Americas (SIDALC). The Thesaurus and Glossary can be downloaded in XML, RDF-SKOS, PDF, MARC, and DOC formats. Resources in this dataset:Resource Title: NAL Thesaurus and Glossary Home.

《美国国家农业图书馆农业术语表》（NALT）首次由美国国家农业图书馆于2002年发布，涵盖了农业、生物学及其相关学科的深入内容。该术语表包含超过135,000个术语，其中63,000个为交叉引用，并按17个主题类别编排，便于在特定学科或主题领域中浏览术语表。NALT每年一月份进行更新。术语表中农业的主题范围被广泛定义，并包括支持生物学、物理学和社会科学的相关术语。生物学命名学构成了术语表中的多数术语，并位于“生物分类学”主题类别中。政治地理主要在国家层面上进行描述。自2007年出版以来，《术语表》收录了与《美国国家农业图书馆农业术语表》创建相结合的农业术语的定义。2018年版术语表包含涵盖农业及其众多相关主题的5,618个术语，其中大部分定义由美国国家农业图书馆术语表工作人员撰写。来自政府来源的定义在“定义来源”字段中标注，并包含在书目中。2010年，该术语表作为关联开放数据提供。关联开放数据将信息转换为计算机可读和可理解的形式。这种转换使得不同信息资源，如网页、数据集和研究文章，能够相互连接，建立有意义的联系，从而便于查找相关内容。2007年5月，其西班牙语版本的《美国国家农业图书馆农业术语表》（NALT）和《农业术语汇编》以西班牙语名称“Tesauro Agrícola”和“Glosario”发布。术语表和汇编由美国农业部国家农业图书馆、美洲间农业合作研究所（IICA）以及其他美洲农业信息与文献服务（SIDALC）所属的拉丁美洲农业机构合作制作。术语表和汇编可下载为XML、RDF-SKOS、PDF、MARC和DOC格式。本数据集包含的资源：资源标题：《美国国家农业图书馆术语表和汇编首页》。文件名：网页，网址：https://agclass.nal.usda.gov/agt.shtml，美国国家农业图书馆术语表（NALT）和汇编的网站。
