Vasily

Vasily is a gem for using textocat.com API from Ruby.

Installation

Add this line to your application's Gemfile:

gem 'vasily'

And then execute:

$ bundle

Or install it yourself as:

$ gem install vasily

Usage

To use API, first you need to obtain (free) token from textocat.com. Then you can use it to initialize client:

client = Vasily::Client.new('auth_token')
client.status # => 200

Let's analyze some documents!

doc1 = Vasily::Document.new("Председатель совета директоров ОАО «МДМ Банк» Олег Вьюгин — о том, чему приведет обмен санкциями между Россией и Западом в следующем году. Беседовала Светлана Сухова.", "doc1")
doc2 = Vasily::Document.new("Не перепутает Генри Форда и компанию «Форд» в документах", "doc2")
doc3 = Vasily::Document.new("Штаб-квартира компании Форд Моторс располагается в городе Дирборн.", "doc3")
batch_id, status = client.queue([doc1, doc2, doc3]) # => ["abcdefgh-1111-2222-3333-abcdefabcdef", "IN_PROGRESS"]
status = client.request(batch_id) # => "FINISHED"

To retrieve entities:

entities = client.retrieve([batch_id])
puts JSON.pretty_generate(entities)
[
  {
    "status": "SUCCESS",
    "tag": "doc1",
    "entities": [
      {
        "span": "Председатель совета директоров ОАО «МДМ Банк» Олег Вьюгин",
        "category": "PERSON",
        "beginOffset": 0,
        "endOffset": 57
      },
      ...
    ]
  },
  {
    "status": "SUCCESS",
    "tag": "doc2",
    "entities": [
      ...
    ]
  },
  ...
]

To perform search:

search_result = client.search('ORGANIZATION:форд')
puts JSON.pretty_generate(search_result)
[
  {
    "status": "SUCCESS",
    "tag": "doc2",
    "entities": [
      {
        "span": "Генри Форда",
        "category": "PERSON",
        "beginOffset": 14,
        "endOffset": 25
      },
      {
        "span": "компанию «Форд»",
        "category": "ORGANIZATION",
        "beginOffset": 28,
        "endOffset": 43
      }
    ]
  },
  ...
]
