jaottelua

Jaottelua is a Finnish term referring to the act and result of dividing or organizing items into groups or categories according to shared characteristics or criteria. It is derived from the verb jaotella, meaning to distribute, separate, or classify. In Finnish, jaottelu can describe both the process of categorizing and the arrangement that emerges from that process, such as a classification scheme or a grouping scheme.

The concept is used across various fields. In information science and library work, jaottelu describes classification systems that structure knowledge into subject areas, topics, or metadata tags, often employing hierarchical or faceted approaches. In statistics and data analysis, jaottelu can mean partitioning a data set into subsets, such as bins or clusters, for analysis. In mathematics, it may denote the partition of a set into disjoint blocks. In social sciences and policy, jaottelu is used to refer to grouping people or phenomena by attributes like age, gender, language, or socio-economic status for study or decision-making.

Common methods include hierarchical jaottelu, which creates nested levels of categories; faceted jaottelu, which uses multiple independent attributes; and rule-based jaottelu, which relies on explicit criteria. The term is closely related to, yet broader than, luokittelu (classification) and ryhmittely (grouping). As with any categorization, jaottelu depends on purpose and criteria and may evolve as new information or perspectives emerge.
