Knowledge Assessment
摘要
A knowledge graph is not created once but needs to be curated continuously to ensure a high quality. Knowledge assessment is the first step of curating a knowledge graph. We introduce quality dimensions, their metrics and calculation functions, as well as how to calculate a weighted aggregated quality score. We present some assessment tools and explain one of them in a larger detail. We provide an indicative example on how correctness (accuracy) of a knowledge graph can be calculated based on the German Tourism Knowledge Graph.
