A semantic relatedness metric based on free link structure (short paper)
Sander Wubben, Antal P. J. 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 Finkelstein353 dataset we show that a shortest path metric run on Wikipedia attains a better correlation than WordNet-based metrics. ConceptNet attains a good correlation as well, but suffers from a low concept coverage.
