Documentation

Overview

Package language is an auto-generated package for the Cloud Natural Language API.

Provides natural language understanding technologies, such as sentiment analysis, entity recognition, entity sentiment analysis, and other text annotations, to developers.

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

For information about setting deadlines, reusing contexts, and more please visit https://pkg.go.dev/cloud.google.com/go.

Functions

func DefaultAuthScopes added in v0.8.0 

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

Types

type CallOptions 

type CallOptions struct {
	AnalyzeSentiment       []gax.CallOption
	AnalyzeEntities        []gax.CallOption
	AnalyzeEntitySentiment []gax.CallOption
	AnalyzeSyntax          []gax.CallOption
	ClassifyText           []gax.CallOption
	AnnotateText           []gax.CallOption
}

CallOptions contains the retry settings for each method of Client.

type Client 

type Client struct {

	// The call options for this service.
	CallOptions *CallOptions
	// contains filtered or unexported fields
}

Client is a client for interacting with Cloud Natural Language API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

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

func NewClient 

func NewClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

NewClient creates a new language service client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

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

Example 
package main

import (
	"context"

	language "cloud.google.com/go/language/apiv1"
)

func main() {
	ctx := context.Background()
	c, err := language.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}

Output:

func (*Client) AnalyzeEntities 

func (c *Client) AnalyzeEntities(ctx context.Context, req *languagepb.AnalyzeEntitiesRequest, opts ...gax.CallOption) (*languagepb.AnalyzeEntitiesResponse, error)

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

Example 
package main

import (
	"context"

	language "cloud.google.com/go/language/apiv1"
	languagepb "google.golang.org/genproto/googleapis/cloud/language/v1"
)

func main() {
	ctx := context.Background()
	c, err := language.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &languagepb.AnalyzeEntitiesRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.AnalyzeEntities(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (*Client) AnalyzeEntitySentiment added in v0.14.0 

func (c *Client) AnalyzeEntitySentiment(ctx context.Context, req *languagepb.AnalyzeEntitySentimentRequest, opts ...gax.CallOption) (*languagepb.AnalyzeEntitySentimentResponse, error)

AnalyzeEntitySentiment finds entities, similar to AnalyzeEntities in the text and analyzes sentiment associated with each entity and its mentions.

Example 
package main

import (
	"context"

	language "cloud.google.com/go/language/apiv1"
	languagepb "google.golang.org/genproto/googleapis/cloud/language/v1"
)

func main() {
	ctx := context.Background()
	c, err := language.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &languagepb.AnalyzeEntitySentimentRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.AnalyzeEntitySentiment(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (*Client) AnalyzeSentiment 

func (c *Client) AnalyzeSentiment(ctx context.Context, req *languagepb.AnalyzeSentimentRequest, opts ...gax.CallOption) (*languagepb.AnalyzeSentimentResponse, error)

AnalyzeSentiment analyzes the sentiment of the provided text.

Example 
package main

import (
	"context"

	language "cloud.google.com/go/language/apiv1"
	languagepb "google.golang.org/genproto/googleapis/cloud/language/v1"
)

func main() {
	ctx := context.Background()
	c, err := language.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &languagepb.AnalyzeSentimentRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.AnalyzeSentiment(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (*Client) AnalyzeSyntax 

func (c *Client) AnalyzeSyntax(ctx context.Context, req *languagepb.AnalyzeSyntaxRequest, opts ...gax.CallOption) (*languagepb.AnalyzeSyntaxResponse, error)

AnalyzeSyntax analyzes the syntax of the text and provides sentence boundaries and tokenization along with part of speech tags, dependency trees, and other properties.

Example 
package main

import (
	"context"

	language "cloud.google.com/go/language/apiv1"
	languagepb "google.golang.org/genproto/googleapis/cloud/language/v1"
)

func main() {
	ctx := context.Background()
	c, err := language.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &languagepb.AnalyzeSyntaxRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.AnalyzeSyntax(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (*Client) AnnotateText 

func (c *Client) AnnotateText(ctx context.Context, req *languagepb.AnnotateTextRequest, opts ...gax.CallOption) (*languagepb.AnnotateTextResponse, error)

AnnotateText a convenience method that provides all the features that analyzeSentiment, analyzeEntities, and analyzeSyntax provide in one call.

Example 
package main

import (
	"context"

	language "cloud.google.com/go/language/apiv1"
	languagepb "google.golang.org/genproto/googleapis/cloud/language/v1"
)

func main() {
	ctx := context.Background()
	c, err := language.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &languagepb.AnnotateTextRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.AnnotateText(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (*Client) ClassifyText added in v0.17.0 

func (c *Client) ClassifyText(ctx context.Context, req *languagepb.ClassifyTextRequest, opts ...gax.CallOption) (*languagepb.ClassifyTextResponse, error)

ClassifyText classifies a document into categories.

Example 
package main

import (
	"context"

	language "cloud.google.com/go/language/apiv1"
	languagepb "google.golang.org/genproto/googleapis/cloud/language/v1"
)

func main() {
	ctx := context.Background()
	c, err := language.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &languagepb.ClassifyTextRequest{
		// TODO: Fill request struct fields.
	}
	resp, err := c.ClassifyText(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}
