Python - WordNet NLTK KeyError

Question

私は実際にそれを取得しません。私はWordNetを使用しており、困っています。私はそのような文字列で次のメソッドを呼び出します。

F2F - プロセスが計画データを作成し、開始し、入庫を作成し、入庫が

def lemmatise(word, pos=NOUN): 
     return WordNetLemmatizer().lemmatize(word, pos) 

を作成し、この1は、次のメソッドを呼び出します：

def lemmatize(self, word, pos=NOUN): 
    lemmas = wordnet._morphy(word, pos) 
    return min(lemmas, key=len) if lemmas else word 

を

そして、morphy（）メソッドは、エラーが原因で問題が発生したことを示します（エラーメッセージを参照）。

def _morphy(self, form, pos): 
    # from jordanbg: 
    # Given an original string x 
    # 1. Apply rules once to the input to get y1, y2, y3, etc. 
    # 2. Return all that are in the database 
    # 3. If there are no matches, keep applying rules until you either 
    # find a match or you can't go any further 
L1687 exceptions = self._exception_map[pos] 
     substitutions = self.MORPHOLOGICAL_SUBSTITUTIONS[pos]

奇妙なことは、それがランダムに、それも同じ入力でエラーをスロー単語を切り替えていることです。私を助けてください！

Answer 1

長い文字列ではなく1文字で渡すことを確認してください。これらは、ソースnltk.corpus.reader.wordnetの定数セクションにあります。 {品詞定数ADJ、ADJ_SAT、ADV、NOUN、VERB = 'a'、 's'、 'r'、 'n' 'v'＃}
