Application skills of Chinese rewriting in Java software

Abstract: Chinese rewriting refers to the process of converting a Chinese text into another Chinese expression with similar meaning. In Java software development, Chinese rewriting can improve user experience and search engine optimization. This article will introduce the application skills of Chinese rewriting and provide specific code examples.

1. Selection of NLP library

When rewriting Chinese in Java, we can use the natural language processing (NLP) library to help us with sentence segmentation and part-of-speech tagging , syntax analysis and other operations. Commonly used NLP libraries include HanLP, Stanford NLP and NLPIR. The following is a sample code using HanLP for word segmentation:

import com.hankcs.hanlp.HanLP;
import com.hankcs.hanlp.seg.common.Term;

public class NLPExample {
    public static void main(String[] args) {
        String sentence = "我家的狗很可爱。";
        List<Term> termList = HanLP.segment(sentence);
        for (Term term : termList) {
            System.out.println(term.word);
        }
    }
}

2. Synonym replacement

A common method for Chinese rewriting is to use synonym replacement. By replacing certain words in the text with words that have a similar meaning to them, you can change the way the sentence is expressed to make it more relevant to the user's needs. The following is a sample code that uses HanLP to implement synonym replacement:

import com.hankcs.hanlp.HanLP;
import com.hankcs.hanlp.suggest.Suggester;

public class SynonymReplacement {
    public static void main(String[] args) {
        Suggester suggester = new Suggester();
        suggester.addSentence("苹果是一种水果。");
        suggester.addSentence("苹果手机很受欢迎。");
        String input = "我想买个手机。";
        List<String> suggestList = suggester.suggest(input, 1);
        if (suggestList.size() > 0) {
            String suggestion = suggestList.get(0);
            String output = input.replace("手机", suggestion);
            System.out.println(output);
        }
    }
}

3. Antonym replacement

In addition to using synonym replacement, we can also use antonym replacement for Chinese rewriting. By replacing certain words in the text with words that have the opposite meaning, you can change the meaning of a sentence. The following is a sample code that uses HanLP to implement antonym replacement:

import com.hankcs.hanlp.HanLP;
import com.hankcs.hanlp.dictionary.stopword.CoreStopWordDictionary;
import com.hankcs.hanlp.seg.common.Term;
import com.hankcs.hanlp.tokenizer.StandardTokenizer;

import java.io.IOException;
import java.util.List;

public class AntonymReplacement {
    public static void main(String[] args) {
        String sentence = "这个电影太好看了。";
        List<Term> termList = StandardTokenizer.segment(sentence);
        for (Term term : termList) {
            if (!CoreStopWordDictionary.contains(term.word)) {
                String opposite = getOpposite(term.word);
                if (opposite != null) {
                    sentence = sentence.replace(term.word, opposite);
                }
            }
        }
        System.out.println(sentence);
    }
    
    public static String getOpposite(String word) {
        // 返回和word意思相反的词
        return null;
    }
}

Summary: Chinese rewriting is an important part of Java software development and can improve user experience and search engine optimization. By choosing an appropriate NLP library and using techniques such as synonym replacement and antonym replacement, we can rewrite Chinese text.
