'''Concept-based image indexing''', also variably named as “description"description-based”based" or “text"text-based”based" image indexing/retrieval, refers to retrieval from text-based indexing of images that may employ keywords, subject headings, captions, or natural language text (Chen & Rasmussen, 1999). It is opposed to '''[[Content-based image retrieval]]'''.

Chu (2001) confirms that there exist two distinctive research groups employing the content-based and description-based approaches, respectively. However, research in the content-based ___domain is currently dominating in the field, while the other approach has less visibility.
