I wonder if keyphrase extraction by RAKE and short sentence extraction are related.
-
Key phrase extraction can be divided into two phases
- Creating keyphrase candidates
- Scoring key phrase candidates
-
I think concentration (of one’s attention) could be used for scoring.
-
When RAKE is compared to CRF, the “two or more occurrences” feature is different from a simple CRF [Global Features
-
Order by set size of candidate key phrases
- explicit human-powered set
- noun phrase
- stop-word increment
- RAKE-like coupling
- substring
-
Order by length of key phrase candidates
- character
- word
- stop-word increment
- RAKE-like coupling
- punctuation marks
- short piece of writing (e.g. passage, article, composition)
