Knowledge Organization System (KOS)

A Knowledge Organization System (KOS) is a structured way to categorize and organize information so that related concepts are grouped and easy to find. It includes tools like catalogs, taxonomies, thesauri, or classifications that define relationships among ideas or items. KOS helps users locate, manage, and understand information efficiently, whether in libraries, databases, or digital archives. By creating a shared, organized framework, KOS improves searchability and ensures consistent terminology across systems, making complex collections more accessible and navigable for everyone.
