type CallOptions ¶

CallOptions contains the retry settings for each method of Client.

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

type Client ¶

Client is a client for interacting with Google Cloud Natural Language API.

type Client struct {

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

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, 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.

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) AnalyzeEntitySentiment ¶

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

AnalyzeEntitySentiment finds entities, similar to [AnalyzeEntities][google.cloud.language.v1beta2.LanguageService.AnalyzeEntities] in the text and analyzes sentiment associated with each entity and its mentions.

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

req := &languagepb.AnalyzeEntitySentimentRequest{
// TODO: Fill request struct fields.
}
resp, err := c.AnalyzeEntitySentiment(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, opts ...gax.CallOption) (*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, 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.

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, opts ...gax.CallOption) (*languagepb.AnnotateTextResponse, error)

AnnotateText a convenience method that provides all syntax, sentiment, and entity features 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
