(In) formal classification : connecting formal and informal knowledge organization systems

TL;DRAbstract

Recent developments in knowledge organization systems (KOS) have added new dimensions to traditional classification practices, as knowledge is now not only organized by official committees and editors, but also by the users of these systems themselves.\nThe aim of this study is to provide new insights into mapping formally created knowledge organization systems to socially created knowledge organization systems. To this end, a literature review, a theoretical analysis and a practical analysis have been carried out. The theoretical analysis consists of a comparison between the knowledge structure of Freebase, a semantic encyclopedia based on Linked Open Data, and the Dewey Decimal Classification (DDC), a traditional classification system. The practical analysis is based on a statistical mapping of Freebase “domains” to classes of the Dewey Decimal Classification, using information available in the WorldCat database. This analysis is of a quantitative nature.\nThe findings of this study
