NASA thesaurus. Volume 1: Hierarchical Listing

There are over 17,000 postable terms and nearly 4,000 nonpostable terms approved for use in the NASA scientific and technical information system in the Hierarchical Listing of the NASA Thesaurus. The generic structure is presented for many terms. The broader term and narrower term relationships are shown in an indented fashion that illustrates the generic structure better than the more widely used BT and NT listings. Related terms are generously applied, thus enhancing the usefulness of the Hierarchical Listing. Greater access to the Hierarchical Listing may be achieved with the collateral use of Volume 2 - Access Vocabulary and Volume 3 - Definitions

NASA thesaurus. Volume 2: Access vocabulary

The access vocabulary, which is essentially a permuted index, provides access to any word or number in authorized postable and nonpostable terms. Additional entries include postable and nonpostable terms, other word entries and pseudo-multiword terms that are permutations of words that contain words within words. The access vocabulary contains almost 42,000 entries that give increased access to the hierarchies in Volume 1 - Hierarchical Listing

SKUA - retrofitting semantics

Abstract. The Semantic Web promises much for software developers, but because its claimed benefits are rather abstract, there is little obvious incentive to master its unfamiliar technology. In contrast, many ‘Social Web ’ applications seem rather trivial, and not obviously useful for astronomy. The SKUA project (Semantic Knowledge Underpinning Astronomy) is implementing a service which will realise the benefits of both these web technologies. This RESTful web service gives application authors ready access to simple persistence, simple (social) sharing, and lightweight semantics, at a low software-engineering cost. The SKUA service allows applications to persist assertions (such as bookmarks and ratings), and share them between users. On top of this, it provides lightweight, astronomy-specific, semantics to enhance the usefulness and retrieval of the users ’ data.
