TextAnalyticsClient Classe

Analizzare il sentiment per un batch di documenti. Attivare il data mining di opinione con show_opinion_mining.

Restituisce una stima del sentiment, nonché i punteggi di sentiment per ogni classe sentiment (Positivo, Negativo e Neutral) per il documento e ogni frase all'interno di essa.

Vedere https://aka.ms/azsdk/textanalytics/data-limits per i limiti dei dati del servizio.

Novità nella versione 3.1: argomenti della parola chiave show_opinion_mining, disable_service_logs e string_index_type .

Istanza di textAnalysisLROPoller. Chiama result() nell'oggetto poller per restituire un elenco eterogeneo paginabile di elenchi. Questo elenco di elenchi viene prima ordinato dai documenti immessi, quindi ordinato dalle azioni immesse. Ad esempio, se si dispone di documenti di input ["Hello", "world"]e azioni RecognizeEntitiesAction e AnalyzeSentimentAction, quando si esegue l'iterazione dell'elenco di elenchi, si eseguirà prima di tutto l'iterazione sui risultati dell'azione per il documento "Hello", recuperando "Hello", quindi l'oggetto RecognizeEntitiesResultAnalyzeSentimentResult "Hello". Poi, si otterrà il RecognizeEntitiesResult e AnalyzeSentimentResult di "mondo".

Analizzare le entità sanitarie e identificare le relazioni tra queste entità in un batch di documenti.

Le entità sono associate ai riferimenti disponibili nelle knowledge base esistenti, ad esempio UMLS, CHV, MSH e così via.

Estraiamo anche le relazioni tra entità, ad esempio in "Il soggetto ha preso 100 mg di ibuprofen", si estrae la relazione tra il dosaggio "100 mg" e il farmaco "ibuprofen".
