“…Each LIS program uses different titles and labels for KO courses, which differ in coverage and content. Some relevant KO content can be categorized as information and knowledge maps (Dodge, 2005; Bargent, 2001), indexing tools (Hjørland, 2008, Anderson and Perez-Carballo, 2001), thesauri (Hill et al , 2002), metadata (Hsieh-Yee, 2004) KM, subject headings (Hodge, 2000; Walsh, 2010; Wiggins, 2007) taxonomy, ontology (Urs and Angrosh, 2008) and social tagging (Allam, 2010). Some LIS schools offer advanced courses, both core and elective, which are devoted solely to KO, using the schemes such as classification, subject headings, Machine-Readable (MARC)-based cataloging and metadata.…”
