How to use

This package utilizes Rxjs, therefore with every call to the service you will be able to perform all observable actions.

Below are a few examples

const GNLService = require('gnl').service;
 
...

let gnlService = new GNLService();

// call analyze sentiment
gnlService.analyzeSentiment("The Village is a great movie no matter what anyone says")
    .subscribe( results => console.log(results));


// call annotate text service -- basic call
gnlService.annotateText("The Village is a great movie no matter what anyone says. It was a great thriller.")
    .subscribe( results => console.log(results));

// analyze the annotated tokens
gnlService.annotateText("The Village is a great movie no matter what anyone says. It was a great thriller.")
    .flatMap( data => data.tokens)
    .subscribe( results => console.log(results));

// analyze the annotated sentences
gnlService.annotateText("The Village is a great movie no matter what anyone says. It was a great thriller.")
    .flatMap( data => data.tokens)
    .subscribe( results => console.log(results));



// drill down to get the mentions!
gnlService.analyzeEntities("The Village is a great movie no matter what anyone says")
    .flatMap( results => results.entities)
    .flatMap( entity => entity.mentions )
    .subscribe( mentions => console.log(mentions));
