The SAGE Social Science Thesaurus is a multidisciplinary vocabulary of the most important concepts in the social sciences. SAGE uses this vocabulary as its principal keyword vocabulary for automated tagging of content on SAGE Knowledge and SAGE Research Methods. You are welcome to browse, download, use and transform the vocabulary for any non-commercial purpose. The majority of concepts in the thesaurus have been mined from headwords in SAGE encyclopedias and other reference works. Relationships between concepts have been inferred from implicit structures in those works, for example subject indexes and readers' guides. As such, the thesaurus is a structured representation of what the editors of those reference works consider to be the most important concepts in the social sciences. Additional scraping work has extracted and structured concept-specific metadata, such as dates (for events and people) and definitions. In addition to broader-narrower relationships, concepts are grouped by type: concepts, people, organizations, events, methods, theories or laws.

SCOP(e) unique identifier. This is simply a number that may be used to reference any entry in the SCOP(e) hierarchy, from root to leaves (Fold, Superfamily, Family, etc.).

This is a dot notation used to concisely describe a SCOP(e) class, fold, superfamily, and family. For example, a.39.1.1 references the 'Calbindin D9K' family, where 'a' represents the class, '39' represents the fold, '1' represents the superfamily, and the last '1' represents the family.

A 7-character sid consists of "d" followed by the 4-character PDB ID of the file of origin, the PDB chain ID ('_' if none, '.' if multiple as is the case in genetic domains), and a single character (usually an integer) if needed to specify the domain uniquely ('_' if not). Sids are currently all lower case, even when the chain letter is upper case. Example sids include d4akea1, d9hvpa_, and d1cph.1.

Scopus is the largest abstract and citation database of peer-reviewed literature: scientific journals, books and conference proceedings. Delivering a comprehensive overview of the world's research output in the fields of science, technology, medicine, social sciences, and arts and humanities, Scopus features smart tools to track, analyze and visualize research.

The SciCrunch Registry holds metadata records that describe digital resources, e.g., software, databases, projects and also services. Most of these are produced as a result of government funding and are available to the scientific community. Resources are manually curated to make sure the information is accurate. We also use a web crawler to find literature mentions for the resources.
