package language

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

Package language is an experimental, auto-generated package for the language API.

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

Types ¶

type CallOptions ¶

type CallOptions struct {
	AnalyzeSentiment []gax.CallOption
	AnalyzeEntities  []gax.CallOption
	AnalyzeSyntax    []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 Google Cloud Natural Language API.

func NewClient ¶

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

NewClient creates a new language service client.

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

{
	ctx := context.Background()
	c, err := language.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use client.
	_ = c
}

func (*Client) AnalyzeEntities ¶

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

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

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

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

func (*Client) AnalyzeSentiment ¶

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

AnalyzeSentiment analyzes the sentiment of the provided text.

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

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

func (*Client) AnalyzeSyntax ¶

func (c *Client) AnalyzeSyntax(ctx context.Context, req *languagepb.AnalyzeSyntaxRequest) (*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.

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

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

func (*Client) AnnotateText ¶

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

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

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

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

func (*Client) Close ¶

func (c *Client) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*Client) Connection ¶

func (c *Client) Connection() *grpc.ClientConn

Connection returns the client's connection to the API service.

func (*Client) SetGoogleClientInfo ¶

func (c *Client) SetGoogleClientInfo(keyval ...string)

SetGoogleClientInfo sets the name and version of the application in the `x-goog-api-client` header passed on each request. Intended for use by Google-written clients.
