语义搜索相关配置

1.打开services项目,在pom文件中引入依赖如下

<dependency>
    <groupId>com.hankcs</groupId>
    <artifactId>hanlp</artifactId>
    <version>portable-1.8.3</version>
</dependency>

2.在hanlp github下载语言模型,放入项目根目录下

3.在services项目中,找到hanlpconfig,配置需要加载的模型路径

4.调用相关接口返回相关结果

public static void main(String[] args) throws IOException
    {
        WordVectorModel wordVectorModel = trainOrLoadModel();
        printNearest("上海", wordVectorModel);
        printNearest("美丽", wordVectorModel);
        printNearest("购买", wordVectorModel);
        System.out.println(wordVectorModel.similarity("上海", "广州"));
        System.out.println(wordVectorModel.analogy("日本", "自民党", "共和党"));

        // 文档向量
        DocVectorModel docVectorModel = new DocVectorModel(wordVectorModel);
        String[] documents = new String[]{
            "山东苹果丰收",
            "农民在江苏种水稻",
            "奥运会女排夺冠",
            "世界锦标赛胜出",
            "中国足球失败",
        };

        System.out.println(docVectorModel.similarity(documents[0], documents[1]));
        System.out.println(docVectorModel.similarity(documents[0], documents[4]));

        for (int i = 0; i < documents.length; i++)
        {
            docVectorModel.addDocument(i, documents[i]);
        }

        printNearestDocument("体育", documents, docVectorModel);
        printNearestDocument("农业", documents, docVectorModel);
        printNearestDocument("我要看比赛", documents, docVectorModel);
        printNearestDocument("要不做饭吧", documents, docVectorModel);
    }
