Categorizable

Categorizable is an adjective meaning capable of being categorized or classified. It is formed from the verb categorize and the suffix -able. The term is used across disciplines such as philosophy, linguistics, information science, and data management to describe objects, phenomena, or concepts whose attributes allow them to be placed into a category within a taxonomy or classification scheme.

Philosophical discussions of categorizability address whether a thing has a determinate position in a system of distinctions. Issues such as vagueness, polysemy, context dependence, and the granularity of the scheme can affect categorizability. Some items are highly categorizable in one context but not in another; others may belong to multiple categories or require hierarchies.

In information science and knowledge organization, categorizable items are those that can be assigned to one or more classes with stable meaning. Clear categorizability supports retrieval, reasoning, and interoperability, whereas poor categorizability can hinder search and data integration. In machine learning, features or instances are described as categorizable when labels are well-defined and the target taxonomy is agreed upon; otherwise, annotation can be inconsistent.

Examples include a medical record entry classified under patient demographics, a plant identified as a species within a genus, or a news article tagged by topic. Abstract notions like beauty or justice may be only partially categorizable depending on the framework.

Related concepts include classification, taxonomy, ontology, and categorization, as well as fuzzy or probabilistic categorization when boundaries are not sharp.
