Java Stanley NLP：语音标签的一部分？

Question

斯坦福 NLP，在此处进行了演示，给出了这样的输出：

Colorless/JJ green/JJ ideas/NNS sleep/VBP furiously/RB ./.

What do the Part of语音标签是什么意思？我无法找到官方名单。是斯坦福大学自己的系统，还是他们使用通用标签？ （例如，JJ 是什么？）

此外，例如，当我遍历句子、查找名词时，我最终会执行一些操作，例如检查标签 .contains （'N'）。这感觉很弱。有没有更好的方法来以编程方式搜索某个词性？

Answer 1

宾夕法尼亚大学树库项目。查看词性标记 ps。

JJ是形容词。 NNS 是名词，复数。 VBP 是动词现在时。 RB是副词。

那是为了英语。对于中国人来说，这是宾大中文树库。对于德语来说，它是 NEGRA 语料库。

1. CC 并列连词
2. CD 基数
3. DT 确定符
4. EX存在主义
5. FW 外来词
6. IN 介词或从属连词
7. JJ形容词

Answer 7

关于查找特定 POS（例如，名词）标记的单词/块的第二个问题，这里是您可以遵循的示例代码。

public static void main(String[] args) {
    Properties properties = new Properties();
    properties.put("annotators", "tokenize, ssplit, pos, lemma, ner, parse");
    StanfordCoreNLP pipeline = new StanfordCoreNLP(properties);

    String input = "Colorless green ideas sleep furiously.";
    Annotation annotation = pipeline.process(input);
    List<CoreMap> sentences = annotation.get(CoreAnnotations.SentencesAnnotation.class);
    List<String> output = new ArrayList<>();
    String regex = "([{pos:/NN|NNS|NNP/}])"; //Noun
    for (CoreMap sentence : sentences) {
        List<CoreLabel> tokens = sentence.get(CoreAnnotations.TokensAnnotation.class);
        TokenSequencePattern pattern = TokenSequencePattern.compile(regex);
        TokenSequenceMatcher matcher = pattern.getMatcher(tokens);
        while (matcher.find()) {
            output.add(matcher.group());
        }
    }
    System.out.println("Input: "+input);
    System.out.println("Output: "+output);
}

输出是：

Input: Colorless green ideas sleep furiously.
Output: [ideas]

它们似乎是布朗语料库标签。

Answer 9

用于其他语言的斯坦福 CoreNLP 标签：法语、西班牙语、德语 ...

我看到您使用英语语言的解析器，这是默认模型。
您可以将解析器用于其他语言（法语、西班牙语、德语...），并且请注意，每种语言的分词器和词性标注器都是不同的。如果您想这样做，则必须下载该语言的特定模型（例如使用 Maven 等构建器），然后设置您要使用的模型。
在这里您可以了解更多相关信息。

这里是不同语言的标签列表：

1. Stanford CoreNLP POS Tags for西班牙语
2. Stanford CoreNLP POS Tagger for German 使用 Stuttgart-Tübingen 标签集 (STTS)
3. 法语的斯坦福 CoreNLP 词性标注器使用以下标签：

法语标签：

ET    (foreign word)
I     (interjection)
NC    (common noun)

Answer 10

在 spacy 中，我认为速度非常快，在低端笔记本中，它将像这样运行：

import spacy
import time

start = time.time()

with open('d:/dictionary/e-store.txt') as f:
    input = f.read()

word = 0
result = []

nlp = spacy.load("en_core_web_sm")
doc = nlp(input)

for token in doc:
    if token.pos_ == "NOUN":
        result.append(token.text)
    word += 1

elapsed = time.time() - start

print("From", word, "words, there is", len(result), "NOUN found in", elapsed, "seconds")

几次试验中的输出：

From 3547 words, there is 913 NOUN found in 7.768507719039917 seconds
From 3547 words, there is 913 NOUN found in 7.408619403839111 seconds
From 3547 words, there is 913 NOUN found in 7.431427955627441 seconds

所以，我认为您不需要担心每个 POS 标签检查的循环:)

更多禁用某些管道时我得到的改进：

nlp = spacy.load("en_core_web_sm", disable = 'ner')

所以，结果更快：

From 3547 words, there is 913 NOUN found in 6.212834596633911 seconds
From 3547 words, there is 913 NOUN found in 6.257707595825195 seconds
From 3547 words, there is 913 NOUN found in 6.371225833892822 seconds
