在这里演示的斯坦福 NLP给出了这样的输出:
Colorless/JJ green/JJ ideas/NNS sleep/VBP furiously/RB ./.
词性标签是什么意思?我找不到正式的名单。是斯坦福自己的系统,还是他们使用通用标签?(JJ
例如,什么是?)
此外,例如,当我遍历句子、寻找名词时,我最终会做一些事情,比如检查 tag 是否为.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?

JJ是形容词。NNS是名词,复数。VBP 是动词现在时。RB是副词。
那是给英语的。对于中国人来说,它是 Penn Chinese Treebank。对于德语,它是 NEGRA 语料库。

关于查找特定 POS(例如,名词)标记的词/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);
}
输出是:
Input: Colorless green ideas sleep furiously.
Output: [ideas]
它们似乎是Brown Corpus 的标签。
斯坦福 CoreNLP 其他语言标签:法语、西班牙语、德语 ...
我看到您使用英语解析器,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不同。如果您想这样做,您必须下载该语言的特定模型(例如使用 Maven 之类的构建器),然后设置您要使用的模型。 在这里,您可以获得更多相关信息。
以下是不同语言的标签列表:
法语标签:
法语的词性标签
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)
法语短语类别标签:
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)
法语的句法功能:
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)
我认为在 spacy 中它非常快,在低端笔记本中它会像这样运行:
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")
多次试验的输出:
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,我认为你不必担心每个 POS 标签检查的循环:)
禁用某些管道时我得到了更多改进:
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
