OpenAmplify

The OpenAmplify API reads text you supply and returns linguistic data explaining and classifying the content. What you do with that analysis is, in the fine tradition of APIs and mashups, up to you. Some possibilities might include pairing ads with articles, creating rich tag-clouds, or monitoring the tone of forum threads.

Supported version

2.1

Helpful links

Install

gem install openamplify

Usage

Configure

OpenAmplify.configure do |config|
  config.api_key = 'YOUR_API_KEY'

  # default :get
  config.method = :post

  # default :xml
  config.output_format = :json

  # default :all
  config.analysis = :topics

  # default :standard
  config.scoring = :todo
end

Default settings can be overriden by the client

client = OpenAmplify::Client.new(:method => :get)

Or when you start 'amplifying'.

result = client.amplify('input', :output_format => :rdf)

Usage

client = OpenAmplify::Client.new

text = "After getting the MX1000 laser mouse and the Z-5500 speakers i fell in love with logitech"
analysis = client.amplify(text)
puts analysis  # default as xml

It knows if the input is a URL and uses the right webservice param (ie. sourceurl)

client.amplify('http://theonion.com')

In case you need a different format, OpenAmplify supports XML, JSON, RDF, CSV. It can also return the result as a fancy HTML page.

# assuming you use Nokogiri
doc = Nokogiri::XML(analysis.to_xml)

# or you want a JSON
json = JSON.parse(analysis.to_json)

# you should really try the pretty formats
puts analysis.to_pretty
# or
puts analysis.to_signals

Command-line

OpenAmplify gem comes with a command-line tool.

openamplify --api-key=APIKEY --format=json --analysis=topics "sample input text"

Upgrading from 0.2.3 to 0.3.0

Note 0.3.0 is a major revamp of the code. In general, it is better but if you encounter a problem, please let me know. Or better, submit a pull request.

The following methods are deprecated and will be removed in 0.3.1

client.analyze_text('input')
client.base_url = 'http://domain.dev'

The following methods are no longer supported. I figure it's better to let the caller decide how they want to traverse the results.

# Treating the result as hash
response.each do |k, v|
  pp k
  pp v
end

# 'response' works like a Hash
puts response['Topics']

# Nor the shortcuts
response.top_topics
response.proper_nouns
response.locations
response.domains

Testing

rake test OPEN_AMPLIFY_KEY=YOUR_KEY
