Overview

Ruby Client for Google Cloud Natural Language API (Alpha)

Google Cloud Natural Language API: Google Cloud Natural Language API provides natural language understanding technologies to developers. Examples include sentiment analysis, entity recognition, and text annotations.

Quick Start

In order to use this library, you first need to go through the following steps:

  1. Select or create a Cloud Platform project.
  2. Enable billing for your project.
  3. Enable the Google Cloud Natural Language API.
  4. Setup Authentication.

Installation

$ gem install google-cloud-language

Preview

LanguageServiceClient

require "google/cloud/language"

language_service_client = Google::Cloud::Language.new(version: :v1)
content = "Hello, world!"
type = :PLAIN_TEXT
document = { content: content, type: type }
response = language_service_client.analyze_sentiment(document)

Next Steps

Enabling Logging

To enable logging for this library, set the logger for the underlying gRPC library. The logger that you set may be a Ruby stdlib Logger as shown below, or a Google::Cloud::Logging::Logger that will write logs to Stackdriver Logging. See grpc/logconfig.rb and the gRPC spec_helper.rb for additional information.

Configuring a Ruby stdlib logger:

require "logger"

module MyLogger
  LOGGER = Logger.new $stderr, level: Logger::WARN
  def logger
    LOGGER
  end
end

# Define a gRPC module-level logger method before grpc/logconfig.rb loads.
module GRPC
  extend MyLogger
end

Class Method Details

.new(credentials: nil, scopes: nil, client_config: nil, timeout: nil, metadata: nil, exception_transformer: nil, lib_name: nil, lib_version: nil) ⇒ Object

Provides text analysis operations such as sentiment analysis and entity recognition.

Parameters:

  • credentials (Google::Auth::Credentials, String, Hash, GRPC::Core::Channel, GRPC::Core::ChannelCredentials, Proc) —

    Provides the means for authenticating requests made by the client. This parameter can be many types. A Google::Auth::Credentials uses a the properties of its represented keyfile for authenticating requests made by this client. A String will be treated as the path to the keyfile to be used for the construction of credentials for this client. A Hash will be treated as the contents of a keyfile to be used for the construction of credentials for this client. A GRPC::Core::Channel will be used to make calls through. A GRPC::Core::ChannelCredentials for the setting up the RPC client. The channel credentials should already be composed with a GRPC::Core::CallCredentials object. A Proc will be used as an updater_proc for the Grpc channel. The proc transforms the metadata for requests, generally, to give OAuth credentials.

  • scopes (Array<String>) —

    The OAuth scopes for this service. This parameter is ignored if an updater_proc is supplied.

  • client_config (Hash) —

    A Hash for call options for each method. See Google::Gax#construct_settings for the structure of this data. Falls back to the default config if not specified or the specified config is missing data points.

  • timeout (Numeric) —

    The default timeout, in seconds, for calls made through this client.

  • metadata (Hash) —

    Default metadata to be sent with each request. This can be overridden on a per call basis.

  • exception_transformer (Proc) —

    An optional proc that intercepts any exceptions raised during an API call to inject custom error handling.
