While Bag of Words approaches such as LSA have performed successfully on the content analysis task in domains such as Computer Literacy (Wiemer-Hastings et al., 1998), they have been demonstrated to perform poorly in causal domains such as research methods (Malatesta et al., 2002) because they base their predictions only on the words included in a text and not on the functional relationships between them.
we propose CarmelTC as an alternative.
