Getting Started with AYLIEN Text Analysis API Using Ruby

Requirements

  • Ruby (>= 1.9)

Getting the SDK

The easiest way to get the Ruby SDK is to use RubyGems.

$ gem install aylien_text_api

Using the SDK

The following example demonstrates how to calculate the sentiment of a simple sentence, and determine the language it's written in.

require "aylien_text_api"

AylienTextApi.configure do |config|
  config.app_id  = "YourApplicationId"
  config.app_key = "YourApplicationKey"
end
client = AylienTextApi::Client.new

# or pass them as parameters to AylienTextApi::Client class.
# client = AylienTextApi::Client.new(app_id: "YourApplicationId", app_key: "YourApplicationKey")

text = "John is a very good football player!"

# returns nil in case of errors
sentiment = client.sentiment text: text

# returns an exception in case of errors
language = client.language! text: text

puts "Sentiment: #{sentiment[:polarity]} (#{sentiment[:polarity_confidence]})"
puts "Language: #{language[:lang]} (#{language[:confidence]})"
