# Azure AI Text Analytics SDK for Python
Client library for Azure AI Language service NLP capabilities including sentiment, entities, key phrases, and more.
## Installation
```bash
pip install azure-ai-textanalytics
```
## Environment Variables
```bash
AZURE_LANGUAGE_ENDPOINT=https://<resource>.cognitiveservices.azure.com
AZURE_LANGUAGE_KEY=<your-api-key> # If using API key
```
## Authentication
### API Key
```python
import os
from azure.core.credentials import AzureKeyCredential
from azure.ai.textanalytics import TextAnalyticsClient
endpoint = os.environ["AZURE_LANGUAGE_ENDPOINT"]
key = os.environ["AZURE_LANGUAGE_KEY"]
client = TextAnalyticsClient(endpoint, AzureKeyCredential(key))
```
### Entra ID (Recommended)
```python
from azure.ai.textanalytics import TextAnalyticsClient
from azure.identity import DefaultAzureCredential
client = TextAnalyticsClient(
endpoint=os.environ["AZURE_LANGUAGE_ENDPOINT"],
credential=DefaultAzureCredential()
)
```
## Sentiment Analysis
```python
documents = [
"I had a wonderful trip to Seattle last week!",
"The food was terrible and the service was slow."
]
result = client.analyze_sentiment(documents, show_opinion_mining=True)
for doc in result:
if not doc.is_error:
print(f"Sentiment: {doc.sentiment}")
print(f"Scores: pos={doc.confidence_scores.positive:.2f}, "
f"neg={doc.confidence_scores.negative:.2f}, "
f"neu={doc.confidence_scores.neutral:.2f}")
# Opinion mining (aspect-based sentiment)
for sentence in doc.sentences:
for opinion in sentence.mined_opinions:
target = opinion.target
print(f" Target: '{target.text}' - {target.sentiment}")
for assessment in opinion.assessments:
print(f" Assessment: '{assessment.text}' - {assessment.sentiment}")
```
## Entity Recognition
```python
documents = ["Microsoft was founded by Bill Gates and Paul Allen in Albuquerque."]
result = client.recognize_entities(documents)
for doc in result:
if not doc.is_error:
for entity in doc.entities:
print(f"Entity: {entity.text}")
print(f" Category: {entity.category}")
print(f" Subcategory: {entity.subcategory}")
print(f" Confidence: {entity.confidence_score:.2f}")
```
## PII Detection
```python
documents = ["My SSN is 123-45-6789 and my email is [email protected]"]
result = client.recognize_pii_entities(documents)
for doc in result:
if not doc.is_error:
print(f"Redacted: {doc.redacted_text}")
for entity in doc.entities:
print(f"PII: {entity.text} ({entity.category})")
```
## Key Phrase Extraction
```python
documents = ["Azure AI provides powerful machine learning capabilities for developers."]
result = client.extract_key_phrases(documents)
for doc in result:
if not doc.is_error:
print(f"Key phrases: {doc.key_phrases}")
```
## Language Detection
```python
documents = ["Ce document est en francais.", "This is written in English."]
result = client.detect_language(documents)
for doc in result:
if not doc.is_error:
print(f"Language: {doc.primary_language.name} ({doc.primary_language.iso6391_name})")
print(f"Confidence: {doc.primary_language.confidence_score:.2f}")
```
## Healthcare Text Analytics
```python
documents = ["Patient has diabetes and was prescribed metformin 500mg twice daily."]
poller = client.begin_analyze_healthcare_entities(documents)
result = poller.result()
for doc in result:
if not doc.is_error:
for entity in doc.entities:
print(f"Entity: {entity.text}")
print(f" Category: {entity.category}")
print(f" Normalized: {entity.normalized_text}")
# Entity links (UMLS, etc.)
for link in entity.data_sources:
print(f" Link: {link.name} - {link.entity_id}")
```
## Multiple Analysis (Batch)
```python
from azure.ai.textanalytics import (
RecognizeEntitiesAction,
ExtractKeyPhrasesAction,
AnalyzeSentimentAction
)
documents = ["Microsoft announced new Azure AI features at Build conference."]
poller = client.begin_analyze_actions(
documents,
actions=[
RecognizeEntitiesAction(),
ExtractKeyPhrasesAction(),
AnalyzeSentimentAction()
]
)
results = poller.result()
for doc_results in results:
for result in doc_results:
if result.kind == "EntityRecognition":
print(f"Entities: {[e.text for e in result.entities]}")
elif result.kind == "KeyPhraseExtraction":
print(f"Key phrases: {result.key_phrases}")
elif result.kind == "SentimentAnalysis":
print(f"Sentiment: {result.sentiment}")
```
## Async Client
```python
from azure.ai.textanalytics.aio import TextAnalyticsClient
from azure.identity.aio import DefaultAzureCredential
async def analyze():
async with TextAnalyticsClient(
endpoint=endpoint,
credential=DefaultAzureCredential()
) as client:
result = await client.analyze_sentiment(documents)
# Process results...
```
## Client Types
| Client | Purpose |
|--------|---------|
| `TextAnalyticsClient` | All text analytics operations |
| `TextAnalyticsClient` (aio) | Async version |
## Available Operations
| Method | Description |
|--------|-------------|
| `analyze_sentiment` | Sentiment analysis with opinion mining |
| `recognize_entities` | Named entity recognition |
| `recognize_pii_entities` | PII detection and redaction |
| `recognize_linked_entities` | Entity linking to Wikipedia |
| `extract_key_phrases` | Key phrase extraction |
| `detect_language` | Language detection |
| `begin_analyze_healthcare_entities` | Healthcare NLP (long-running) |
| `begin_analyze_actions` | Multiple analyses in batch |
## Best Practices
1. **Use batch operations** for multiple documents (up to 10 per request)
2. **Enable opinion mining** for detailed aspect-based sentiment
3. **Use async client** for high-throughput scenarios
4. **Handle document errors** — results list may contain errors for some docs
5. **Specify language** when known to improve accuracy
6. **Use context manager** or close client explicitly
## When to Use
This skill is applicable to execute the workflow or actions described in the overview.
