关于找到特定POS（例如，名词）标记的单词/块的第二个问题，这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);
}输出为：
Input: Colorless green ideas sleep furiously.
Output: [ideas]它们似乎是布朗语料库标签。
Stanford CoreNLP其他语言的标签：法语，西班牙语，德语...
我看到您使用英语的解析器，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，每种语言的标记器和部分语音标记器都不同。如果要这样做，则必须下载该语言的特定模型（例如，使用Maven之类的构建器），然后设置要使用的模型。 在这里，您有关于此的更多信息。
这里是不同语言的标签列表：
法语标签：
法语的部分语音标签
A (adjective)
Adv (adverb)
CC (coordinating conjunction)
Cl (weak clitic pronoun)
CS (subordinating conjunction)
D (determiner)
ET (foreign word)
I (interjection)
NC (common noun)
NP (proper noun)
P (preposition)
PREF (prefix)
PRO (strong pronoun)
V (verb)
PONCT (punctuation mark)法语的短语分类标签：
AP (adjectival phrases)
AdP (adverbial phrases)
COORD (coordinated phrases)
NP (noun phrases)
PP (prepositional phrases)
VN (verbal nucleus)
VPinf (infinitive clauses)
VPpart (nonfinite clauses)
SENT (sentences)
Sint, Srel, Ssub (finite clauses)法语的语法功能：
SUJ (subject)
OBJ (direct object)
ATS (predicative complement of a subject)
ATO (predicative complement of a direct object)
MOD (modifier or adjunct)
A-OBJ (indirect complement introduced by à)
DE-OBJ (indirect complement introduced by de)
P-OBJ (indirect complement introduced by another preposition)我认为这是很快的，在一个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")在几个试验中的输出：
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因此，我认为您无需担心每个POS标签检查的循环:)
当禁用某些管道时，我得到了更多改进：
nlp = spacy.load("en_core_web_sm", disable = 'ner')因此，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
.starts_with('N')而不是contains，因为'IN'和'VBN'也包含'N'。这可能是找到标记者认为哪些单词是名词的最佳方法。
