トークナイザーの使い方

from nltk.tokenize import word_tokenize, sent_tokenize
# 对句子进行分词
sentence = "Hello, how are you? I hope you are doing well."
tokens = word_tokenize(sentence)
print(tokens) # 输出分词结果
# 对文本进行句子分割
text = "This is the first sentence. This is the second sentence."
sentences = sent_tokenize(text)
print(sentences) # 输出句子分割结果

import java.util.StringTokenizer;
public class TokenizerExample {
public static void main(String[] args) {
// 对字符串进行分割
String str = "apple,banana,orange";
StringTokenizer tokenizer = new StringTokenizer(str, ",");
while (tokenizer.hasMoreTokens()) {
System.out.println(tokenizer.nextToken());
}
}
}

// 对字符串进行分割
var str = "apple,banana,orange";
var tokens = str.split(",");
console.log(tokens); // 输出分割结果
4、C++中的Tokenizer用法(使用std::stringstream)：
在C++中，可以使用std::stringstream来对字符串进行分割。
#include
#include
#include
int main() {
// 对字符串进行分割
std::string str = "apple,banana,orange";
std::stringstream ss(str);
std::string token;
while (std::getline(ss, token, ',')) {
std::cout << token << std::endl;
}
return 0;
}
