Identify feature synonyms
Liu et al (WWW-05) made an attempt using only WordNet.
Carenini et al (K-CAP-05) proposed a more sophisticated method based on several similarity metrics, but it requires a taxonomy of features to be given.
The system merges each discovered feature to a feature node in the taxonomy.
The similarity metrics are defined based on string similarity, synonyms and other distances measured using WordNet.
Experimental results based on digital camera and DVD reviews show promising results.
Many ideas in information integration are applicable.
