Knowledge Graphs and Network Text Analysis

Roel Popping

Dr Roel Popping, Department of Sociology, University of Groningen, NL9712TG Groningen 31, Netherlands. R.Popping{at}PPSW.RUG.NL

A knowledge graph is a kind of semantic network representing some scientific theory. The article describes the present state of this field and addresses a number of problems that have not yet been solved. These problems are implicit relations, strength of (causal) relations, and exclusiveness. Concepts might be too broad or complex to be used properly, so directions for solving these problems are explored. The solutions are applied to a knowledge graph in the field of labour markets.

Key Words: Knowledge graphs • Knowledge representation
