aliluokitus
Aliluokitus, literally “subclassification” in Finnish, refers to the process of creating subordinate categories within an existing classification framework in order to increase granularity and improve the organization and retrieval of information. It is used across information management disciplines, including libraries, archives, data catalogs, and taxonomy projects, to structure complex subjects into smaller, more specific groups under a common parent category.
Etymology and scope: The term combines alili- or ali- (sub-) with luokitus (classification). In practice, aliluokitus
Applications and benefits: Introducing subcategories supports more precise indexing, refined search results, analytics, and intuitive navigation.
Implementation considerations: Effective aliluokitus requires clear rules, governance, and version control to avoid drift and fragmentation.
