创建 StanfordCoreNLP 对象时出错 [英] Error in creating the StanfordCoreNLP object

问题描述

我已经从 http://nlp.stanford.edu 下载并安装了所需的 jar 文件/software/corenlp.shtml#Download.

我已经包含了五个 jar 文件

I have include the five jar files

Satnford-postagger.jar

Satnford-postagger.jar

Stanford-psotagger-3.3.1.jar

Stanford-psotagger-3.3.1.jar

Stanford-psotagger-3.3.1.jar-javadoc.jar

stanford-corenlp-3.3.1.jar

stanford-corenlp-3.3.1.jar

代码是

public class lemmafirst {

    protected StanfordCoreNLP pipeline;

    public lemmafirst() {
        // Create StanfordCoreNLP object properties, with POS tagging
        // (required for lemmatization), and lemmatization
        Properties props;
        props = new Properties();
        props.put("annotators", "tokenize, ssplit, pos, lemma");

        /*
         * This is a pipeline that takes in a string and returns various analyzed linguistic forms. 
         * The String is tokenized via a tokenizer (such as PTBTokenizerAnnotator), 
         * and then other sequence model style annotation can be used to add things like lemmas, 
         * POS tags, and named entities. These are returned as a list of CoreLabels. 
         * Other analysis components build and store parse trees, dependency graphs, etc. 
         * 
         * This class is designed to apply multiple Annotators to an Annotation. 
         * The idea is that you first build up the pipeline by adding Annotators, 
         * and then you take the objects you wish to annotate and pass them in and 
         * get in return a fully annotated object.
         * 
         *  StanfordCoreNLP loads a lot of models, so you probably
         *  only want to do this once per execution
         */
        ***this.pipeline = new StanfordCoreNLP(props);***
}

我的问题在于创建管道.

My Problem is in creating a the pipline.

我得到的错误是:

谁能更正错误?谢谢

推荐答案

抛出的异常是由于缺少 pos 模型.这是因为有带和不带模型文件的可下载版本.

The exception which is thrown is due to the missing pos model. This is because there are downloadable versions with and without the model files.

无论你添加stanford-postagger-完整-3.3.1.jar可在以下页面 (stanford-postagger-full-2014-01-04.zip) 上找到:http://nlp.stanford.edu/software/tagger.shtml.

Either you add stanford-postagger-full-3.3.1.jar which can be found on the following page (stanford-postagger-full-2014-01-04.zip): http://nlp.stanford.edu/software/tagger.shtml .

或者您对整个 CoreNLP 包 (stanford-corenlp-full....jar) 执行相同操作:http://nlp.stanford.edu/software/corenlp.shtml(然后您也可以删除所有 postagger 依赖项，它们包含在 CoreNLP 中)

Or you do the same for the whole CoreNLP Package (stanford-corenlp-full....jar): http://nlp.stanford.edu/software/corenlp.shtml (Then you can drop all the postagger depenedencies too, they are included in CoreNLP)

如果您只想添加模型文件，请查看 Maven Central 并下载stanford-corenlp-3.3.1-models.jar".

In case you only want to add the model files, look at Maven Central and download "stanford-corenlp-3.3.1-models.jar".
