在Java中使用Stanford Core NLP時遇到錯誤（tokensregex.parser.TokenMgrError）

Question

我收到此錯誤錯誤：edu.stanford.nlp.ling.tokensregex.parser.TokenMgrError：Encountered：“ \\'”，在“”之后

我正在使用斯坦福核心nlp的最新2016-10-31版本，這是我的代碼

  static MaxentTagger tagger = new MaxentTagger("C:/Users/Sam/Desktop/stanford-corenlp-full-2016-10-31/stanford-corenlp-full-2016-10-31/edu/stanford/nlp/models/pos-tagger/english-left3words/english-left3words-distsim.tagger"); tokens = new ArrayList<CoreLabel>(); properties = new Properties(); properties.put("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref"); pipeline = new StanfordCoreNLP(properties); this.sentenceFeatures = Main.pipeline.process(textFeatures) .get(CoreAnnotations.SentencesAnnotation.class); for(CoreMap sentence: this.sentenceFeatures) { // **using TokensRegex** for (CoreLabel token: sentence.get(TokensAnnotation.class)){ Main.tokens.add(token); } this.p1 = TokenSequencePattern.compile(this.textFeatures); this.matcher = p1.getMatcher(Main.tokens); for (CoreLabel token: sentence.get(TokensAnnotation.class)) { String words = token.get(TextAnnotation.class); this.wordsList.add(words); String tagged = Main.tagger.tagString(words); this.wordsList.add(tagged); this.no_of_words++; this.no_of_chars += words.length(); } } 

而

  textFeatures = "At the western corner of the northern peninsula of Michigan you'll find Porcupine Mountains Wilderness State Park that is a true gem for a great family vacation , and the largest State Park in Michigan too.It has many things to offer to families looking for adventure in the great outdoors.And it's accessible during all the seasons of the year.The Park got its name from the Ojibwa Indians, who named the 'small mountains' thus, because, with their tall trees, they looked like crouching porcupines.Visit in the spring as the leaves begin to bud.Call on it in the summer lambing season.Greet it in the Autumn as the leaves begin to fall.Love it in the winter skying season.Its terrain is wild and rugged where it sits at the shoreline of Lake Superior, and inland where it embraces sixty-thousand acres of towering pines and sturdy birches and natural hemlock forests.The rivers teem with various species of trout as they cut through the forests." 

我得到的異常是：

Answer 1

TokenSequencePattern應該是您要編譯的規則，而不是您要在其中找到模式的文本。

這也是TokensRegex的一般參考：
