Amphibian Species of the World (ASW) - obsolete: Amphibian Species of the World - obsolete

Data from Frost, Darrel R. 2018. Amphibian Species of the World: an Online Reference. Version 6.0. Electronic Database accessible at http://research.amnh.org/herpetology/amphibia/index.html. American Museum of Natural History, New York, USA.
With revised identifiers.
The Encyclopedia of Life (EOL, eol.org) aggregates biodiversity information from more than 400 sources and provides access to the data through taxon pages, visual query and application programming interfaces. Scientific names are essential elements of the data integration infrastructure, but their shortcomings as key identifiers are well documented (Patterson et al., 2016). Complex automated workflows and continuous manual curation are required to address idiosyncrasies of source taxonomies, variation in data quality, and conflicting taxonomic opinions.

To achieve a harmonized taxonomic view of EOL content, names from data sources are mapped to a dynamic reference hierarchy ([see current version here](
https://opendata.eol.org/dataset/tram-807-808-809-810-dh-v1-1/resource/00adb47b-57ed-4f6b-8f66-83bfdb5120e8)) using an algorithm that leverages canonical name strings, hierarchical information (ancestry, descendants), taxonomic ranks, synonym data, and author strings. Names that cannot be associated with a reference taxon are still accessible, but their unmapped status excludes them and any associated content from certain core EOL functions.

本数据集的数据源自Frost, Darrel R.于2018年发布的《世界两栖动物物种：在线参考手册》（第6.0版），该电子数据库可通过https://research.amnh.org/herpetology/amphibia/index.html 访问，由美国纽约的美国自然历史博物馆（American Museum of Natural History）提供。标识符已做修订。

生命百科全书（Encyclopedia of Life, 简称EOL，eol.org）整合了来自400余个数据源的生物多样性信息，并通过分类群页面、可视化查询工具及应用程序编程接口（Application Programming Interface, 简称API）提供数据访问渠道。科学名称是数据整合基础设施的核心要素，但学界已充分证实其作为关键标识符的局限性（Patterson等人，2016）。为解决源分类体系的特异性、数据质量参差不齐以及分类学观点冲突等问题，需要依托复杂的自动化工作流与持续的人工编校工作。

为实现EOL内容的统一分类学视图，本数据集采用依托标准名称字符串、层级信息（祖先、后代）、分类阶元、同物异名数据以及作者字符串的算法，将数据源中的名称映射至动态参考层级体系[详见当前版本](https://opendata.eol.org/dataset/tram-807-808-809-810-dh-v1-1/resource/00adb47b-57ed-4f6b-8f66-83bfdb5120e8)。无法关联至参考分类群的名称仍可被访问，但因其未完成映射，这类名称及其关联内容将无法使用EOL的部分核心功能。
