Abstract:
|
Authority control has long been used in library catalogue systems to handle
the problem of ambiguous identifiers for entities, especially authors. With electronic and networked collections the need for authority control is only increased,
and made more important by the possibility of extending defined entities to
cover the content of full-text collections.
The Entity Authority Tool Set (EATS) is a web application for recording,
editing, and using authority information about entities. EATS was developed at
the New Zealand Electronic Text Centre (NZETC) and is now used to manage
the 30,000+ entities represented in the NZETC online collection of signi cant
New Zealand and Pacific Island texts. This paper sets out the requirements for
an entity authority system and makes the case that no existing system suits all
of those needs. It presents the EATS model for representing entity authority
information, and describes the NZETC implementation of the model along with
associated tools. |
