The document discusses automatic metadata generation (AMG) as an alternative to manual metadata entry by librarians. An evaluation of AMG found no significant difference in quality between metadata generated automatically and metadata generated manually. AMG aims to remove barriers to metadata entry by integrating automatic generation into existing systems and content, rather than introducing new technologies. The quality of automatically generated metadata depends as much on the quality of the data and context used as on the technology itself.
