Replacing frames by Intersective Levin Classes[]
Giulea and Moschitti (2006)[1] propose to use ILC as feature in semantic role labeling instead of frame information. Since there is vastly more data (e.g. PropBank) to train a classifier for ILC than FrameNet frames, this approach helps increase coverage.
Their experiments show that the use of ILC results in a negligible drop in performance, i.e. ILC carries pretty much the same information as FrameNet frames.
The mapping between frames and ILC can be problematic though:
- frames can be defined over adjectives and nouns while ILC are for verbs only
- one frame may correspond to many ILC
- one ILC may correspond to many frames
- a frame and a ILC can form overlapping verb groups
TODO: how big are those problems?
Drawback: complicated, waste (don't use) FrameNet annotations.
Generating new examples[]
Bauer and Rambow (2011)[2] use FrameNet corpus and VerbNet equivalent classes to generate new examples.
