Thesaurus In general usage, a thesaurus is a reference work that lists words grouped together according to similarity of meaning (containing synonyms and sometimes antonyms), in contrast to a dictionary, which provides definitions for words, and generally lists them in alphabetical order. The main purpose of such reference works is to help the user “to find the word, or words, by which [an] idea may be most fitly and aptly expressed” – to quote Peter Mark Roget, architect of the best known thesaurus in the English language.[1] Although including synonyms, a thesaurus should not be taken as a complete list of all the synonyms for a particular word. The entries are also designed for drawing distinctions between similar words and assisting in choosing exactly the right word. Unlike a dictionary, a thesaurus entry does not give the definition of words. Etymology[edit] History[edit] In antiquity, Philo of Byblos authored the first text that could now be called a thesaurus.

Search Engine Land: Must Read News About Search Marketing & Search Engines Dewey Web Services For a long time, the Dewey team at OCLC has wanted to do something with Linked Data. That is, apply Linked Data principles to parts of the Dewey Decimal Classification and present the data as a small “terminology service.” The service should respond to regular HTTP requests with either a machine- or a human-readable presentation of Dewey classes. There should be a URI (and, even better, a Web page that delivers a useful description) for every Dewey concept, not just single classes. The data should be presented in a format that is capable of handling rich semantic information and in a way that allows users or user agents to just “follow their nose” to explore the data. Along comes dewey.info Tim Berners-Lee's new-ish Linked Data meme “Raw Data Now!” For now, the latter approach seemed a more effective driving force that prompted us to confront several different issues that are relevant for either one.
