Stanford Parser의 새 모델을 만드는 데 몇 가지 문제가 있습니다.
Stanford에서 마지막 버전도 다운로드했습니다. http://nlp.stanford.edu/software/lex-parser.shtml
그리고 여기에는 xml과 ptb (Penn Treebank)의 두 가지 형식의 Genia Corpus가 있습니다.
Standford Parser는 ptd 파일로 학습 할 수 있습니다. 그런 다음 생의학 텍스트 작업을 원하기 때문에 Genia Corpus를 다운로드했습니다.
http://categorizer.tmit.bme.hu/~illes/genia_ptb/ (더 이상 사용할 수없는 링크) (genia_ptb.tar.gz)
그런 다음 하나의 생체 의학 문장의 종속성 표현을 얻기 위해 짧은 Main 클래스가 있습니다.
String treebankPath = "/stanford-parser-2012-05-22/genia_ptb/GENIA_treebank_v1/ptb";
Treebank tr = op.tlpParams.diskTreebank();
tr.loadPath(treebankPath);
LexicalizedParser lpc=LexicalizedParser.trainFromTreebank(tr,op);
나는 다른 방법을 시도했지만 항상 같은 결과를 얻습니다.
마지막 줄에 오류가 있습니다. 이것은 내 결과입니다.

이 말뭉치로 새 모델을 어떻게 만들 수 있습니까?
