Types of Knowledge models

Implicit and explicit Semantics

Content is King?

▸ Natural languages

▸ Ambiguity versus Universality▸ Context information and background knowledge needed

Susan observes Mike on a tower with a telescope.

Context is King!

can use it.- Mike and Michael are the same person.- A Celestron is a type of telescope

SKOS business value

• A simple, well-defined, easy to understand format for taxonomies

• An extensible model for flexible taxonomy building

• A fundamental building block for semantic content classification

Cost trade-off

Thesauruses provide an "interpretive layer of semantics" between what we are looking for and the information stored in databases, file systems, the web or any other place where we try to store and retrieve information. (ANSI/NISO, 2005, S.11)
