For each word, the table also shows the number of senses, the total number of examples, and two baselines: a simple informed baseline that selects the most frequent sense by default, 5 and a more refined baseline that 5 Note that this baseline assumes the availability of a sense tagged corpus in order to determine the most frequent sense of a word.
rather than using the senses listed in a disambiguation page as the sense inventory for a given ambiguous word, we chose instead to collect all the annotations available for that word in the Wikipedia pages, and then map these labels to a widely used sense inventory, namely WordNet.
