خلاصه	Facet analysis is the analytico-synthetic technique, pioneered by S. R. Ranganathan and systematized for special schemes by Brian Vickery, for decomposing a subject into its fundamental conceptual components. Instead of trying to enumerate every compound topic in advance, the analyst breaks a subject down into elementary concepts (isolates), sorts those isolates into a small number of fundamental categories — in Ranganathan's canonical scheme Personality, Matter, Energy, Space, and Time (PMEST) — and arranges each resulting facet as an ordered array. A defined citation order then prescribes how facets recombine, so any compound subject can be synthesized from its parts. Facet analysis is the conceptual engine beneath faceted classification, thesaurus structure, and much modern metadata, taxonomy, and interface design.	Literary warrant analysis is the method of justifying the classes and terms of a knowledge-organization system by reference to the actual content of a domain's published literature, rather than to abstract logic or a designer's intuition. The principle, traceable to E. Wyndham Hulme's 1911 idea that classification should be warranted by the books that exist, was given an empirical, corpus-based operationalization by Clare Beghtol in her study of fiction studies, where she used subject descriptors in a bibliographic database to quantify how strongly the domain's literature supported particular concepts and where the field reached consensus. Within Hjørland and Albrechtsen's domain-analysis programme, literary warrant is the empirical anchor that ties a classification or thesaurus to the discourse it serves. The analysis assembles a representative corpus, extracts and counts concepts, measures their warrant, gauges consensus, and lets that evidence determine what the system should contain and how finely it should distinguish.
