A semantic relatedness metric based on free link structure
Sander Wubben, Antal van den Bosch · 2009
While shortest paths in WordNet are known to correlate well with semantic similarity, an is-a hierarchy is less suited for estimating semantic relatedness. We demonstrate this by comparing two free scale networks (ConceptNet and Wikipedia) to WordNet. Using the Finkelstein-353 dataset we show that a shortest path metric run on Wikipedia attains a better correlation than WordNet-based metrics. Concept-Net attains a good correlation as well, but suffers from a low concept coverage.
