Overview

Package textanalytics implements the Azure ARM Textanalytics service API version v2.0.

The Text Analytics API is a suite of text analytics web services built with best-in-class Microsoft machine learning algorithms. The API can be used to analyze unstructured text for tasks such as sentiment analysis, key phrase extraction and language detection. No training data is needed to use this API; just bring your text data. This API uses advanced natural language processing techniques to deliver best in class predictions. Further documentation can be found in https://docs.microsoft.com/en-us/azure/cognitive-services/text-analytics/overview

func PossibleAzureRegionsValues 

func PossibleAzureRegionsValues() []AzureRegions

PossibleAzureRegionsValues returns an array of possible values for the AzureRegions const type.

type BaseClient 

type BaseClient struct {
	autorest.Client
	AzureRegion AzureRegions
}

BaseClient is the base client for Textanalytics.

func New 

func New(azureRegion AzureRegions) BaseClient

New creates an instance of the BaseClient client.

func NewWithoutDefaults 

func NewWithoutDefaults(azureRegion AzureRegions) BaseClient

NewWithoutDefaults creates an instance of the BaseClient client.

func (BaseClient) DetectLanguage 

func (client BaseClient) DetectLanguage(ctx context.Context, input BatchInput) (result LanguageBatchResult, err error)

DetectLanguage scores close to 1 indicate 100% certainty that the identified language is true. A total of 120 languages are supported.

input is collection of documents to analyze.

func (BaseClient) DetectLanguagePreparer 

func (client BaseClient) DetectLanguagePreparer(ctx context.Context, input BatchInput) (*http.Request, error)

DetectLanguagePreparer prepares the DetectLanguage request.

func (BaseClient) DetectLanguageResponder 

func (client BaseClient) DetectLanguageResponder(resp *http.Response) (result LanguageBatchResult, err error)

DetectLanguageResponder handles the response to the DetectLanguage request. The method always closes the http.Response Body.

func (BaseClient) DetectLanguageSender 

func (client BaseClient) DetectLanguageSender(req *http.Request) (*http.Response, error)

DetectLanguageSender sends the DetectLanguage request. The method will close the http.Response Body if it receives an error.

func (BaseClient) KeyPhrases 

func (client BaseClient) KeyPhrases(ctx context.Context, input MultiLanguageBatchInput) (result KeyPhraseBatchResult, err error)

KeyPhrases we employ techniques from Microsoft Office's sophisticated Natural Language Processing toolkit. See the <a href="https://docs.microsoft.com/en-us/azure/cognitive-services/text-analytics/overview#supported-languages">Text Analytics Documentation</a> for details about the languages that are supported by key phrase extraction.

input is collection of documents to analyze. Documents can now contain a language field to indicate the text language

func (BaseClient) KeyPhrasesPreparer 

func (client BaseClient) KeyPhrasesPreparer(ctx context.Context, input MultiLanguageBatchInput) (*http.Request, error)

KeyPhrasesPreparer prepares the KeyPhrases request.

func (BaseClient) KeyPhrasesResponder

func (BaseClient) KeyPhrasesSender 

func (client BaseClient) KeyPhrasesSender(req *http.Request) (*http.Response, error)

KeyPhrasesSender sends the KeyPhrases request. The method will close the http.Response Body if it receives an error.

func (BaseClient) Sentiment 

func (client BaseClient) Sentiment(ctx context.Context, input MultiLanguageBatchInput) (result SentimentBatchResult, err error)

Sentiment scores close to 1 indicate positive sentiment, while scores close to 0 indicate negative sentiment. Sentiment score is generated using classification techniques. The input features to the classifier include n-grams, features generated from part-of-speech tags, and word embeddings. See the <a href="https://docs.microsoft.com/en-us/azure/cognitive-services/text-analytics/overview#supported-languages">Text Analytics Documentation</a> for details about the languages that are supported by sentiment analysis.
