Search Engines and Knowledge Organization (or why we still need Knowledge Organization)
In this class, Birger Hjørland discussed why search engines such as Google do not make knowledge organization (KO) superfluous. Some basic principles behind Google were presented (exact match, best match, web site ranking and search is personalization). None of these principles try to do what KO does: map relations between concepts and conceptual relations as reflected in contemporary knowledge. Prof. Hjørland further presented “the semantic staircase” as a classification of knowledge organization systems (KOS) and argued for concepts as the building blocks of KOS and the Thomas Kuhn's theory as a fruitful way to consider concepts in KO.
The class was delivered via Zoom and was attended by 90 participants from 30 countries. Presentation slides are available to all participants via the KO-ED forum on the ISKO UK website.
