The Language service API is a suite of natural language processing (NLP) skills built with the 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, entities recognition, and language detection, and more.

Further documentation can be found in https://docs.microsoft.com/azure/cognitive-services/language-service/overview

Parameters

endpoint (str) – Supported Cognitive Services or Language resource endpoints (protocol and hostname, for example: ‘https://<resource-name>.cognitiveservices.azure.com’).
credential (AzureKeyCredential or AsyncTokenCredential) – Credentials needed for the client to connect to Azure. This can be the an instance of AzureKeyCredential if using a Cognitive Services/Language API key or a token credential from azure.identity.

Keyword Arguments

default_country_hint (str) – Sets the default country_hint to use for all operations. Defaults to “US”. If you don’t want to use a country hint, pass the string “none”.
default_language (str) – Sets the default language to use for all operations. Defaults to “en”.
api_version (str or TextAnalyticsApiVersion) – The API version of the service to use for requests. It defaults to the latest service version. Setting to an older version may result in reduced feature compatibility.

Example:

Creating the TextAnalyticsClient with endpoint and API key.¶

from azure.core.credentials import AzureKeyCredential
from azure.ai.textanalytics.aio import TextAnalyticsClient
endpoint = os.environ["AZURE_LANGUAGE_ENDPOINT"]
key = os.environ["AZURE_LANGUAGE_KEY"]

text_analytics_client = TextAnalyticsClient(endpoint, AzureKeyCredential(key))

Creating the TextAnalyticsClient with endpoint and token credential from Azure Active Directory.¶

from azure.ai.textanalytics.aio import TextAnalyticsClient

Analyze sentiment for a batch of documents. Turn on opinion mining with show_opinion_mining.

Returns a sentiment prediction, as well as sentiment scores for each sentiment class (Positive, Negative, and Neutral) for the document and each sentence within it.

See https://aka.ms/azsdk/textanalytics/data-limits for service data limits.

Parameters

documents (list[str] or list[TextDocumentInput] or list[dict[str, str]]) – The set of documents to process as part of this batch. If you wish to specify the ID and language on a per-item basis you must use as input a list[TextDocumentInput] or a list of dict representations of TextDocumentInput, like {“id”: “1”, “language”: “en”, “text”: “hello world”}.

Keyword Arguments

show_opinion_mining (bool) – Whether to mine the opinions of a sentence and conduct more granular analysis around the aspects of a product or service (also known as aspect-based sentiment analysis). If set to true, the returned SentenceSentiment objects will have property mined_opinions containing the result of this analysis. Only available for API version v3.1 and up.
language (str) – The 2 letter ISO 639-1 representation of language for the entire batch. For example, use “en” for English; “es” for Spanish etc. If not set, uses “en” for English as default. Per-document language will take precedence over whole batch language. See https://aka.ms/talangs for supported languages in Language API.
model_version (str) – This value indicates which model will be used for scoring, e.g. “latest”, “2019-10-01”. If a model-version is not specified, the API will default to the latest, non-preview version. See here for more info: https://aka.ms/text-analytics-model-versioning
show_stats (bool) – If set to true, response will contain document level statistics in the statistics field of the document-level response.
string_index_type (str) – Specifies the method used to interpret string offsets. UnicodeCodePoint, the Python encoding, is the default. To override the Python default, you can also pass in Utf16CodeUnit or TextElement_v8. For additional information see https://aka.ms/text-analytics-offsets
disable_service_logs (bool) – If set to true, you opt-out of having your text input logged on the service side for troubleshooting. By default, the Language service logs your input text for 48 hours, solely to allow for troubleshooting issues in providing you with the service’s natural language processing functions. Setting this parameter to true, disables input logging and may limit our ability to remediate issues that occur. Please see Cognitive Services Compliance and Privacy notes at https://aka.ms/cs-compliance for additional details, and Microsoft Responsible AI principles at https://www.microsoft.com/ai/responsible-ai.

Returns

The combined list of AnalyzeSentimentResult and DocumentError in the order the original documents were passed in.

Return type

list[AnalyzeSentimentResult or DocumentError]

Raises

HttpResponseError or TypeError or ValueError –

Start a long-running operation to perform a variety of text analysis actions over a batch of documents.

We recommend you use this function if you’re looking to analyze larger documents, and / or combine multiple text analysis actions into one call. Otherwise, we recommend you use the action specific endpoints, for example analyze_sentiment().

Note

See the service documentation for regional support of custom action features: https://aka.ms/azsdk/textanalytics/customfunctionalities

Parameters

documents (list[str] or list[TextDocumentInput] or list[dict[str, str]]) – The set of documents to process as part of this batch. If you wish to specify the ID and language on a per-item basis you must use as input a list[TextDocumentInput] or a list of dict representations of TextDocumentInput, like {“id”: “1”, “language”: “en”, “text”: “hello world”}.
actions (list[RecognizeEntitiesAction or RecognizePiiEntitiesAction or ExtractKeyPhrasesAction or RecognizeLinkedEntitiesAction or AnalyzeSentimentAction or ExtractSummaryAction or RecognizeCustomEntitiesAction or SingleCategoryClassifyAction or MultiCategoryClassifyAction or AnalyzeHealthcareEntitiesAction]) – A heterogeneous list of actions to perform on the input documents. Each action object encapsulates the parameters used for the particular action type. The action results will be in the same order of the input actions.

Keyword Arguments

display_name (str) – An optional display name to set for the requested analysis.
language (str) – The 2 letter ISO 639-1 representation of language for the entire batch. For example, use “en” for English; “es” for Spanish etc. If not set, uses “en” for English as default. Per-document language will take precedence over whole batch language. See https://aka.ms/talangs for supported languages in Language API.
show_stats (bool) – If set to true, response will contain document level statistics.
polling_interval (int) – Waiting time between two polls for LRO operations if no Retry-After header is present. Defaults to 5 seconds.
continuation_token (str) – Call continuation_token() on the poller object to save the long-running operation (LRO) state into an opaque token. Pass the value as the continuation_token keyword argument to restart the LRO from a saved state.

Returns

An instance of an AsyncAnalyzeActionsLROPoller. Call result() on the poller object to return a pageable heterogeneous list of lists. This list of lists is first ordered by the documents you input, then ordered by the actions you input. For example, if you have documents input [“Hello”, “world”], and actions RecognizeEntitiesAction and AnalyzeSentimentAction, when iterating over the list of lists, you will first iterate over the action results for the “Hello” document, getting the RecognizeEntitiesResult of “Hello”, then the AnalyzeSentimentResult of “Hello”. Then, you will get the RecognizeEntitiesResult and AnalyzeSentimentResult of “world”.

Return type

AsyncAnalyzeActionsLROPoller[AsyncItemPaged[ list[RecognizeEntitiesResult or RecognizeLinkedEntitiesResult or RecognizePiiEntitiesResult or ExtractKeyPhrasesResult or AnalyzeSentimentResult or ExtractSummaryAction or RecognizeCustomEntitiesResult or SingleCategoryClassifyResult or MultiCategoryClassifyResult or AnalyzeHealthcareEntitiesResult or DocumentError]]]

Raises

HttpResponseError or TypeError or ValueError –

New in version v3.1: The begin_analyze_actions client method.

Analyze healthcare entities and identify relationships between these entities in a batch of documents.

Entities are associated with references that can be found in existing knowledge bases, such as UMLS, CHV, MSH, etc.

We also extract the relations found between entities, for example in “The subject took 100 mg of ibuprofen”, we would extract the relationship between the “100 mg” dosage and the “ibuprofen” medication.

Parameters

documents (list[str] or list[TextDocumentInput] or list[dict[str, str]]) – The set of documents to process as part of this batch. If you wish to specify the ID and language on a per-item basis you must use as input a list[TextDocumentInput] or a list of dict representations of TextDocumentInput, like {“id”: “1”, “language”: “en”, “text”: “hello world”}.

Keyword Arguments

model_version (str) – This value indicates which model will be used for scoring, e.g. “latest”, “2019-10-01”. If a model-version is not specified, the API will default to the latest, non-preview version. See here for more info: https://aka.ms/text-analytics-model-versioning
show_stats (bool) – If set to true, response will contain document level statistics.
language (str) – The 2 letter ISO 639-1 representation of language for the entire batch. For example, use “en” for English; “es” for Spanish etc. If not set, uses “en” for English as default. Per-document language will take precedence over whole batch language. See https://aka.ms/talangs for supported languages in Text Analytics API.
display_name (str) – An optional display name to set for the requested analysis.
fhir_version (str) – The FHIR Spec version that the result will use to format the fhir_bundle on the result object. For additional information see https://www.hl7.org/fhir/overview.html. The only acceptable values to pass in are None and “4.0.1”. The default value is None.
string_index_type (str) – Specifies the method used to interpret string offsets. Can be one of ‘UnicodeCodePoint’ (default), ‘Utf16CodeUnit’, or ‘TextElement_v8’. For additional information see https://aka.ms/text-analytics-offsets
polling_interval (int) – Waiting time between two polls for LRO operations if no Retry-After header is present. Defaults to 5 seconds.

Detect language for a batch of documents.

Returns the detected language and a numeric score between zero and one. Scores close to one indicate 100% certainty that the identified language is true. See https://aka.ms/talangs for the list of enabled languages.

See https://aka.ms/azsdk/textanalytics/data-limits for service data limits.

Parameters

documents (list[str] or list[DetectLanguageInput] or list[dict[str, str]]) – The set of documents to process as part of this batch. If you wish to specify the ID and country_hint on a per-item basis you must use as input a list[DetectLanguageInput] or a list of dict representations of DetectLanguageInput, like {“id”: “1”, “country_hint”: “us”, “text”: “hello world”}.

Keyword Arguments

country_hint (str) – Country of origin hint for the entire batch. Accepts two letter country codes specified by ISO 3166-1 alpha-2. Per-document country hints will take precedence over whole batch hints. Defaults to “US”. If you don’t want to use a country hint, pass the string “none”.
model_version (str) – This value indicates which model will be used for scoring, e.g. “latest”, “2019-10-01”. If a model-version is not specified, the API will default to the latest, non-preview version. See here for more info: https://aka.ms/text-analytics-model-versioning
show_stats (bool) – If set to true, response will contain document level statistics in the statistics field of the document-level response.
disable_service_logs (bool) – If set to true, you opt-out of having your text input logged on the service side for troubleshooting. By default, the Language service logs your input text for 48 hours, solely to allow for troubleshooting issues in providing you with the service’s natural language processing functions. Setting this parameter to true, disables input logging and may limit our ability to remediate issues that occur. Please see Cognitive Services Compliance and Privacy notes at https://aka.ms/cs-compliance for additional details, and Microsoft Responsible AI principles at https://www.microsoft.com/ai/responsible-ai.
