Adding Postgres and ActiveRecord
Getting started - adding dependencies to your project
Gingerice
Gingerice is a simple ruby gem that corrects grammar and spelling errors in your sentences. To use it:
- You provide it with a sentence as a string
- Gingerice will examine this sentence to find problems
- Gingerice will output a hash that contains the total number of mistakes found in the sentence, it describes likely mistakes, it suggests corrections for these mistakes, and provides a the corrected sentence.
The Gem can be found at: https://rubygems.org/gems/gingerice
Installing Gingerice
In your gem file add Gingerice
gem 'gingerice', '~> 1.2', '>= 1.2.2'
Then install your gem using the Terminal (OSX) or Command Prompt (Windows)
bundle install
Usage
To use it, first require the gem at the top of your project.
require 'gingerice'
Next you can use the following code to parse a sentence
text = 'the assigment is soo difficult.'
parser = Gingerice::Parser.new
output = parser.parse text
# print out the findings
puts output
The output is a hash and the correct sentence is stored as a value in the key “result”. It will look something like this:
output:
{
"text" => "the assigment is soo difficult.",
"result" => "The assignment is so difficult.",
"corrections" => [
[0] {
"text" => "the",
"correct" => "The",
"definition" => nil,
"start" => 0,
"length" => 3
},
[1] {
"text" => "assigment",
"correct" => "assignment",
"definition" => a duty that you are assigned to perform (especially in the armed forces)",
"start" => 4,
"length" => 9
},
[2] {
"text" => "soo",
"correct" => "so",
"definition" => to a very great extent or degree,
"start" => 17,
"length" => 3
}
]
}
When you have the output, you can pull the bits of information you want from the hash, for example:
output["corrections"][1]["text"]
#output "assigment"
Using it with Twilio
To use it with Twilio, you might do something like this:
get "/sms/incoming" do
# Get the incoming SMS message content i.e. Body
# and the who the SMS is From
body = params[:Body] || ""
sender = params[:From] || ""
# use the body as input to Gingerice
parser = Gingerice::Parser.new
output = parser.parse body
# print out the findings
puts output
if output["corrections"].length == 0
message = "Thank you for a well constructed sentence."
else
message = "I think you meant to say: " + output["result"]
end
# Build a twilio response object
# This will be sent back in XML
twiml = Twilio::TwiML::MessagingResponse.new do |r|
r.message do |m|
# add the text of the response
m.body( message )
end
end
# send a response to twilio
content_type 'text/xml'
twiml.to_s
end
