The classification model based on RFs uses the features shown in Table 6.
for the combined semantic and syntactic feature, we use two similarity measures between words: path represents the shortest path that connects the senses in the is-a (hypernym/hypnoym) taxonomy and lch represents the Leacock-Chodorow similarity, namely, the shortest path between the senses divided by double the maximum depth in the taxonomy in which the senses occur.
