As an example, consider the second ensemble classifier in Table 7: this classifier excludes the two levels that contain morphological information (morph and all), which represents the most successful individual source of information for our dataset.
work by Hatzivassiloglou and colleagues (Hatzivassiloglou and McKeown, 1993;Hatzivassiloglou and McKeown, 1997;Hatzivassiloglou and wiebe, 2000) used clustering methods to automatically identify adjectival scales from corpora.
