Overview

Project

Google Cloud Natural Language API reveals the structure and meaning of text by offering powerful machine learning models in an easy to use REST API. You can analyze text uploaded in your request or integrate with your document storage on Google Cloud Storage.

See Google::Cloud#language

Examples:

require "google/cloud/language"

language = Google::Cloud::Language.new

content = "Star Wars is a great movie. The Death Star is fearsome."
annotation = language.annotate content

annotation.sentiment.score #=> 0.10000000149011612
annotation.sentiment.magnitude #=> 1.100000023841858
annotation.entities.count #=> 3
annotation.sentences.count #=> 2
annotation.tokens.count #=> 13

Instance Method Summary collapse

#annotate(content, sentiment: false, entities: false, syntax: false, format: nil, language: nil, encoding: nil) ⇒ Annotation (also: #mark, #detect)
Analyzes the content and returns sentiment, entity, and syntactic feature results, depending on the option flags.
#document(content, format: nil, language: nil) ⇒ Document (also: #doc)
Returns a new document from the given content.
#entities(content, format: :text, language: nil, encoding: nil) ⇒ Annotation::Entities
Entity analysis inspects the given text for known entities (proper nouns such as public figures, landmarks, etc.) and returns information about those entities.
#html(content, language: nil) ⇒ Document
Returns a new document from the given content with the format value :html.
#project ⇒ Object
The Language project connected to.
#sentiment(content, format: :text, language: nil, encoding: nil) ⇒ Annotation::Sentiment
Sentiment analysis inspects the given text and identifies the prevailing emotional opinion within the text, especially to determine a writer's attitude as positive, negative, or neutral.
#syntax(content, format: nil, language: nil, encoding: nil) ⇒ Annotation::Syntax
Syntactic analysis extracts linguistic information, breaking up the given text into a series of sentences and tokens (generally, word boundaries), providing further analysis on those tokens.
#text(content, language: nil) ⇒ Document
Returns a new document from the given content with the format value :text.

Instance Method Details

#annotate(content, sentiment: false, entities: false, syntax: false, format: nil, language: nil, encoding: nil) ⇒ `Annotation` Also known as: mark, detect

Analyzes the content and returns sentiment, entity, and syntactic feature results, depending on the option flags. Calling annotate with no arguments will perform all analysis features. Each feature is priced separately. See Pricing for details.

Examples:

require "google/cloud/language"

language = Google::Cloud::Language.new

content = "Star Wars is a great movie. The Death Star is fearsome."
annotation = language.annotate content

annotation.sentiment.score #=> 0.10000000149011612
annotation.sentiment.magnitude #=> 1.100000023841858
annotation.entities.count #=> 3
annotation.sentences.count #=> 2
annotation.tokens.count #=> 13

content (String, Document, Google::Cloud::Storage::File) —
The content to annotate. This can be an Document instance, or any other type that converts to an Document. See #document for details.
sentiment (Boolean) (defaults to: false) —
Whether to perform the sentiment analysis. Optional. The default is false. If every feature option is false, all features will be performed.
entities (Boolean) (defaults to: false) —
Whether to perform the entity analysis. Optional. The default is false. If every feature option is false, all features will be performed.
syntax (Boolean) (defaults to: false) —
Whether to perform the syntactic analysis. Optional. The default is false. If every feature option is false, all features will be performed.
format (String) (defaults to: nil) —
The format of the document (TEXT/HTML). Optional.
language (String) (defaults to: nil) —
The language of the document (if not specified, the language is automatically detected). Both ISO and BCP-47 language codes are accepted. Optional.
encoding (String) (defaults to: nil) —
The encoding type used by the API to calculate offsets. Optional.

Returns:

(Annotation) —
The results for the content analysis.
