Constructor Details

#initialize {|config| ... } ⇒ Client

Create a new LanguageService REST client object.

Examples:


# Create a client using the default configuration
client = ::Google::Cloud::Language::V2::LanguageService::Rest::Client.new

# Create a client using a custom configuration
client = ::Google::Cloud::Language::V2::LanguageService::Rest::Client.new do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the LanguageService client.

Instance Method Details

#analyze_entities(request, options = nil) ⇒ ::Google::Cloud::Language::V2::AnalyzeEntitiesResponse #analyze_entities(document: nil, encoding_type: nil) ⇒ ::Google::Cloud::Language::V2::AnalyzeEntitiesResponse

Finds named entities (currently proper names and common nouns) in the text along with entity types, probability, mentions for each entity, and other properties.

Examples:

Basic example

require "google/cloud/language/v2"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Language::V2::LanguageService::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Language::V2::AnalyzeEntitiesRequest.new

# Call the analyze_entities method.
result = client.analyze_entities request

# The returned object is of type Google::Cloud::Language::V2::AnalyzeEntitiesResponse.
p result

Overloads:

Yields:

  • (result, operation) —

    Access the result along with the TransportOperation object

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.
