Hello!

In this post we will show how easy it is to start using RussianSentimentAnalyzer API on rapidapi in Java.

package com.semanticanalyzer;

import com.mashape.unirest.http.HttpResponse;
import com.mashape.unirest.http.JsonNode;
import com.mashape.unirest.http.Unirest;
import com.mashape.unirest.http.exceptions.UnirestException;

public class RussianSentimentAnalyzerMashapeClient {

    private final static String rapidApiKey = "[PUT_YOUR_RAPIDAPI_KEY_HERE]";

    public static void main(String[] args) throws UnirestException {

        String textToAnnotate = "'ВТБ кстати неплохой банк)'";
        String targetObject = "'ВТБ'";

        // These code snippets use an open-source library. http://unirest.io/java
        HttpResponse response = Unirest.post("https://russiansentimentanalyzer.p.rapidapi.com/rsa/sentiment/polarity/json/")
                .header("x-rapidapi-host", "russiansentimentanalyzer.p.rapidapi.com")
                .header("x-rapidapi-key", rapidApiKey)
                .header("content-type", "application/json")
                .header("accept", "application/json")
                .body("{'text':" + textToAnnotate + ",'object_keywords':" + targetObject + ",'output_format':'json'}")
                .asJson();

        System.out.println("Input text = " + textToAnnotate + "\n" + "Target object:" + targetObject);
        System.out.println("RussianSentimentAnalyzer response:" + response.getBody().toString());
    }
}

In the code snippet above we’ve used the mashape’s Unirest API, that makes HTTP requesting in Java super easy. To make use of it, use the following maven dependency:

<dependency>
          <groupId>com.mashape.unirest</groupId>
          <artifactId>unirest-java</artifactId>
          <version>1.4.9</version>
</dependency>

All you really need to care about is to register at rapidapi.com, sign up for RussianSentimentAnalyzer API and insert your unique rapidapi key into the code, in place of “PUT_YOUR_RAPIDAPI_KEY_HERE”, as a value of the rapidapiKey variable.

If everything has been set right and you have an active account on rapidapi, execute the code and you should see the following output:

Input text = 'ВТБ кстати неплохой банк)'
Target object:'ВТБ'
RussianSentimentAnalyzer response:{"sentiment":"POSITIVE","synonyms":"[ВТБ]"}

Now you can easily hook the API up into your cool Java app and annotate texts in Russian for sentiment!
