content-based

The term is a modern compound adjective formed within English by combining two established words. "Content," with its core idea of "that which is contained," evolved from Latin through French, shifting from a state of being satisfied to denoting substantive information. "Based" derives from the architectural and foundational sense of "base." When combined in the late 20th century, particularly in computing and information science, the compound logically denotes systems or methods whose fundamental operating principle ("base") is the intrinsic subject matter ("content") itself, as opposed to external factors. This construction follows a transparent and productive English pattern for creating technical descriptors, such as "evidence-based" or "rule-based."

Structure: content (subject matter) + based (founded on) - content: From Latin contentus (contained, satisfied), via Old French. In this compound, it functions as a noun meaning "the things that are contained or the subject matter." - based: From the past participle of the verb base (to found, establish), itself from Old French baser and ultimately Latin basis (foundation). It functions as an adjective-forming suffix meaning "having as a foundation" or "founded on."
