自然语言处理预训练模型商品评价购买决策分析-电商领域服务 Quick Start

使用前提：服务开通与资源包购买

• 自然语言处理：开通地址
• NLP自学习平台：开通地址
• 自学习平台资源包：购买地址
• 获取阿里云账号的AccessKey ID 和AccessKey Secret
• 授权子账号（无需子账号，可以忽略此步骤）：RAM鉴权

操作步骤：

1.添加pom依赖

   <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-java-sdk-core</artifactId>
            <version>4.5.25</version>
        </dependency>
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-java-sdk-nlp-automl</artifactId>
            <version>0.0.5</version>
        </dependency>
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-java-sdk-alinlp</artifactId>
            <version>1.0.16</version>
       </dependency>

2.Code Sample

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.nlp_automl.model.v20191111.RunPreTrainServiceRequest;
import com.aliyuncs.nlp_automl.model.v20191111.RunPreTrainServiceResponse;
import com.aliyuncs.profile.DefaultProfile;
import com.google.gson.Gson;

import java.util.HashMap;
import java.util.Map;


//预训练模型 商品评价购买决策分析-电商领域 调用示例
public class Demo3 {
    public static void main(String[] args) throws ClientException{
        DefaultProfile defaultProfile = DefaultProfile.getProfile("cn-hangzhou","XXXXXXXXXX","XXXXXXXXXX");
        IAcsClient client = new DefaultAcsClient(defaultProfile);
        Map<String, Object> map = new HashMap<>();
        map.put("input", "服务态度不好，你们就是这种服务态度的？");
        RunPreTrainServiceRequest request = new RunPreTrainServiceRequest();
        request.setServiceName("Dialog-Analysis");
        //request.setPredictContent(JSON.toJSONString(map));
        request.setPredictContent(new Gson().toJson(map));
        RunPreTrainServiceResponse response = client.getAcsResponse(request);
        System.out.println(response.getPredictResult());
    }
}

3.测试结果

{"sentiment":{"score":1.0,"key":"负"},"emotion":{"score":0.4929790198802948,"key":"抱怨"},"aspectItem":[{"aspectPolarity":"负","terms":[{"aspectTerm":"服务态度","opinionTerm":"不好"}],"positiveProb":0.0,"aspectCategory":"客服-服务","negativeProb":1.0}],"category":{"score":0.45799994468688965,"key":"其他类-其他"},"intent":{"score":0.7565186023712158,"key":"无"}}
