Types of Knowledge Organization Systems
A review of some typical knowledge organization systems shows their scope and applicability to a variety of digital library settings. While there are specific definitions for many of these KOSs in the computer science and information science literature, and even in standards documents, there is debate over these definitions. Terms are often used, particularly in the popular press and in the book trade, in nonstandard ways. Reflecting the scope of this practice, a recent National Information Standards Organization (NISO) workshop on electronic thesauri emphasized the need to improve the definitions of "terminology relating to terminology" (NISO 1999).
