Although there has been a fair amount of work employing linguistically sophisticated analysis of candidate items (e.g., on CE by Lin (1998) and Lin (1999) as well as on ATR by Daille (1996), Jacquemin (1999), and Jacquemin (2001)), these approaches are limited by the difficulty to port grammatical specifications to other domains (in the case of ATR) or by the error-proneness of full general-language parsers (in the case of CE).
most recent approaches in both areas have backed off to more shallow linguistic filtering techniques, such as POS tagging and phrase chunking (e.g., Frantzi et al.
