Overview

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
	AnnotateText     []gax.CallOption
}

CallOptions contains the retry settings for each method of this 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 LanguageService.

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.

Example

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.

Example

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.

Example

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) AnnotateText

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

AnnotateText advanced API that analyzes the document and provides a full set of text annotations, including semantic, syntactic, and sentiment information. This API is intended for users who are familiar with machine learning and need in-depth text features to build upon.

Example

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(name, version 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.
