는 여기에서 촬영 한 자바 스크립트 알고리즘을 형태소 운반되는 : http://tartarus.org/~martin/PorterStemmer/js.txt운반는 방법 아래
단순히 호출하여 알고리즘을 사용할 수 있도록하고 싶습니다:
var stemmed_word = porter_stemming_alg("some_word_to_stem");
누구든지 아래 코드에이 기능을 통합하는 방법에 대한 제안 사항이 있습니까? 의 라인을 따라
뭔가 : 너희들 감사
function porter_stemming_alg(word){
//...
// algorithm goes here...
//...
}
어떤 제안 ....
