如何在Stanford CoreNLP服務器上使用自定義的TokensRegex規則註釋器？

通過命令行使用CoreNLP時TokensRegex規則顏色註釋器（stanford-corenlp-full-2016-10-31/tokensregex/color.rules.txt）加載成功，但對於java.lang.IllegalArgumentException: Unknown annotator: color Web服務器加載失敗。如何在Stanford CoreNLP服務器上使用自定義的TokensRegex規則註釋器？

設置

# custom.properties 
annotators=tokenize,ssplit,pos,lemma,ner,regexner,color 
customAnnotatorClass.color = edu.stanford.nlp.pipeline.TokensRegexAnnotator 
color.rules = tokensregex/color.rules.txt

命令行

$ java -cp "*" -Xmx2g edu.stanford.nlp.pipeline.StanfordCoreNLP -props custom.properties -file ./tokensregex/color.input.txt -outputFormat text 
[main] INFO edu.stanford.nlp.pipeline.StanfordCoreNLP - Registering annotator color with class edu.stanford.nlp.pipeline.TokensRegexAnnotator 
...

解決方案

在請求中包含自定義標註屬性：wget --post-data 'Both blue and light blue are nice colors.' 'localhost:9000/?properties={"color.rules":"tokensregex/color.rules.txt","customAnnotatorClass.color":"edu.stanford.nlp.pipeline.TokensRegexAnnotator","annotators":"tokenize,ssplit,pos,lemma,ner,regexner,color","enforceRequirements":"false","outputFormat":"json"}' -O -

做了所有''ner'，'regexner'和'color'爲你工作？ –

添加

"enforceRequirements":"false"

到你的請求，並應該停止這個錯誤！

謝謝！這給了我一個新的錯誤'java.lang.IllegalArgumentException：沒有註釋器命名爲color'.However，一些搜索後，我發現CoreNLP服務器不加載[傳遞給它的屬性文件]（https://github.com/stanfordnlp/CoreNLP /問題/ 165）。我必須在請求中包含顏色註釋器屬性。 –
