环境：IDEA+jdk8+maven 3.5.2
新建maven项目，添加nlp的maven依赖：
<dependency>
<groupId>org.apache.opennlp</groupId>
<artifactId>opennlp-tools</artifactId>
<version>1.8.4</version>
</dependency>
然后就可以使用nlp的开发工具了。我们来看一些实例：

//divide sentences
public static void SentenceDetect() throws IOException {
String paragraph = “Hi. How are you? This is JD_Dog. He is my good friends.He is very kind.but he is no more handsome than me. “;
InputStream is = new FileInputStream(“E:\\NLP_Practics\\models\\en-sent.bin”);
SentenceModel model = new SentenceModel(is);
SentenceDetectorME sdetector = new SentenceDetectorME(model);
String sentences[] = sdetector.sentDetect(paragraph);
for (String single : sentences) {
System.out.println(single);
}
is.close();
}
这是一个英文分词的实例，我们首先要去下载英文分词的模型，在这里，我将它放到了E:\NLP_Practics\models\目录下。
关于更多模型的下载可以在地址：
http://maven.tamingtext.com/opennlp-models/models-1.5/
中找到。
我们来看下对应的输出结果：

Hi. How are you?
This is JD_Dog.
He is my good friends.He is very kind.but he is no more handsome than me.
是不是很神奇呢？哈哈哈也没什么可神奇的。这里只是使用现有的一个简单模型做了一个示范，模型是从大量的训练数据中具象出来的，因此分析的结果好坏还要取决于你使用的模型。
我们再看一个英文分词的例子：

//devide words
public static void Tokenize() throws IOException {
InputStream is = new FileInputStream(“E:\\NLP_Practics\\models\\en-token.bin”);
TokenizerModel model = new TokenizerModel(is);
Tokenizer tokenizer = new TokenizerME(model);
String tokens[] = tokenizer.tokenize(“Hi. How are you? This is Richard. Richard is still single. please help him find his girl”);
for (String a : tokens)
System.out.println(a);
is.close();
}
运行结果：
