如何实现“java 判断文字相似度”

1.整体流程

下面是实现“java 判断文字相似度”的步骤：

步骤 操作
1 读取两段文字
2 对两段文字进行分词处理
3 计算两段文字的相似度

2.具体操作

步骤1：读取两段文字

// 读取第一段文字
String text1 = "Java is a programming language.";
// 读取第二段文字
String text2 = "Java is a programming language used to develop applications.";

步骤2：对两段文字进行分词处理

// 将文字分词为数组
String[] words1 = text1.split(" ");
String[] words2 = text2.split(" ");

步骤3：计算两段文字的相似度

// 计算相同词汇的数量
int commonWords = 0;
for(String word1 : words1) {
    for(String word2 : words2) {
        if(word1.equals(word2)) {
            commonWords++;
            break;
        }
    }
}

// 计算相似度
double similarity = (double)commonWords / Math.max(words1.length, words2.length);

完整代码示例

public class TextSimilarity {
    public static void main(String[] args) {
        // 读取两段文字
        String text1 = "Java is a programming language.";
        String text2 = "Java is a programming language used to develop applications.";

        // 分词处理
        String[] words1 = text1.split(" ");
        String[] words2 = text2.split(" ");

        // 计算相似度
        int commonWords = 0;
        for(String word1 : words1) {
            for(String word2 : words2) {
                if(word1.equals(word2)) {
                    commonWords++;
                    break;
                }
            }
        }

        double similarity = (double)commonWords / Math.max(words1.length, words2.length);

        System.out.println("Text similarity: " + similarity);
    }
}
