E.g., if the object description contains only one token, the standard cosine-normalization technique (Salton et al., 1975) will yield a normalized score of 1 irrespective of the token.
for a review containing the words "Food" and "Casablanca", the standard normalization will yield the same score for a restaurant named "Food" and a restaurant named "Casablanca", ignoring the fact that "Food" is much more likely to be an object-independent term.
