January 2025

  • .NET SDK for Azure AI Language text analytics, Azure.AI.Language.Text 1.0.0-beta.2, is now available. This client library supports the latest REST API version, 2024-11-01 and 2024-11-15-preview, for the following features:
    • Language detection
    • Sentiment analysis
    • Key phrase extraction
    • Named entity recognition (NER)
    • Personally identifiable information (PII) entity recognition
    • Entity linking
    • Text analytics for health
    • Custom named entity recognition (Custom NER)
    • Custom text classification
    • Extractive text summarization
    • Abstractive text summarization
  • Custom sentiment analysis (preview), custom text analytics for health (preview) and custom summarization (preview) were retired on January 10th, 2025, as Azure AI features are constantly evaluated based on customer demand and feedback. Based on the customers’ feedback of these preview features, Microsoft has decided to retire this feature and prioritize new custom model features leveraging the power of generative AI to better serve customers’ needs.

November 2024

  • Azure AI Language is moving to Azure AI Foundry. These skills are now available in AI Foundry playground: Extract health information, Extract PII from conversation, Extract PII from text, Summarize text, Summarize conversation, Summarize for call center. More skills follow.
  • Runtime Container for Conversational Language Understanding (CLU) is available for on-premise connection.
  • Both our Text PII redaction service and our Conversational PII service preview API (version 2024-11-15-preview) now support the option to mask detected sensitive entities with a label beyond just redaction characters. Customers can specify if personal data content such as names and phone numbers, that is, "John Doe received a call from 424-878-9192", are masked with a redaction character, that is, "******** received a call from ************", or masked with an entity label, that is, "PERSON_1 received a call from PHONENUMBER_1". More on how to specify the redaction policy style for your outputs can be found in our how-to guides.
  • Native document support gating is removed with the latest API version, 2024-11-15-preview, allowing customers to access native document support for PII redaction and summarization. Key updates in this version include:
    • Increased Maximum File Size Limits (from 1 MB to 10 MB).
    • Enhanced PII Redaction Customization: Customers can now specify whether they want only the redacted document or both the redacted document and a JSON file containing the detected entities.
  • Language detection is a preconfigured feature that can detect the language a document is written in and returns a language code for a wide range of languages, variants, dialects, and some regional/cultural languages. Today the general availability of scription detection capability, and 16 more languages support, which adds up to 139 total supported languages is announced.
  • Named Entity Recognition service, Entity Resolution was upgraded to the Entity Metadata starting in API version 2023-04-15-preview. If you're calling the preview version of the API equal or newer than 2023-04-15-preview, check out the Entity Metadata article to use the resolution feature. The service now supports the ability to specify a list of entity tags to be included into the response or excluded from the response. If a piece of text is classified as more than one entity type, the overlapPolicy parameter allows customers to specify how the service will handle the overlap. The inferenceOptions parameter allows for users to adjust the inference, such as excluding the detected entity values from being normalized and included in the metadata. Along with these optional input parameters we support an updated output structure (with new fields tags, type, and metadata) to ensure enhanced user customization and deeper analysis Learn more on our documentation.
  • Text analytics for health (TA4H) is a preconfigured feature that extracts and labels relevant medical information from unstructured texts such as doctor's notes, discharge summaries, clinical documents, and electronic health records. Today, we released support for Fast Healthcare Interoperability Resources (FHIR) structuring and temporal assertion detection in the Generally Available API.
