Implementation of the Rapid Automatic Keyword Extraction algorithm (RAKE)
Broadly based on the python implementation at github.com/fabianvf/python-rake
Based on Rose, S. , Engel, D. , Cramer, N. and Cowley, W. (2010). Automatic Keyword Extraction from Individual Documents. In Text Mining (eds M. W. Berry and J. Kogan). doi:10.1002/9780470689646.ch1
A simple usage example:
import 'package:rake/rake.dart';
main() {
final rake = Rake();
// only keywords with length >= 5
// and at least two occurrences
print(rake.rank('this large world', minChars: 5, minFrequency: 2));
}
