Abstract:Nuovo Soggettario is a verbal subject indexing system renewing the existing Soggettario used in many Italian libraries. The renewal work consists of substantive improvements in the structure and the relationships of the system, now making it a true faceted thesaurus. Facet analysis is a key part of this development, both in identifying a set of facets and categories to which terms in the thesaurus belong, and in providing a scheme of the roles they can play within a subject string, as well as rules for their citation order.
Keywords:Categorial analysis  Facet analysis  Nuovo Soggettario  Subject heading lists  Syntactic roles  Thesauri
