Azure Conversational Language Understanding client library for Python
Conversational Language Understanding - aka CLU for short - is a cloud-based conversational AI service which provides many language understanding capabilities like:
Conversation App: It's used in extracting intents and entities in conversations
Workflow app: Acts like an orchestrator to select the best candidate to analyze conversations to get best response from apps like Qna, Luis, and Conversation App
Conversational Summarization: Used to analyze conversations in the form of issues/resolution, chapter title, and narrative summarizations

Getting started
Prerequisites
Python 3.7 or later is required to use this package.
An Azure subscription
A Language service resource
Install the package
Install the Azure Conversations client library for Python with pip:
pip install azure-ai-language-conversations
Note: This version of the client library defaults to the 2023-04-01 version of the service
Authenticate the client
In order to interact with the CLU service, you'll need to create an instance of the ConversationAnalysisClient class, or ConversationAuthoringClient class. You will need an endpoint, and an API key to instantiate a client object. For more information regarding authenticating with Cognitive Services, see Authenticate requests to Azure Cognitive Services.
Get an API key
You can get the endpoint and an API key from the Cognitive Services resource in the Azure Portal.
Alternatively, use the Azure CLI command shown below to get the API key from the Cognitive Service resource.
az cognitiveservices account keys list --resource-group <resource-group-name> --name <resource-name>
Create ConversationAnalysisClient
Once you've determined your endpoint and API key you can instantiate a ConversationAnalysisClient:
from azure.core.credentials import AzureKeyCredential
from azure.ai.language.conversations import ConversationAnalysisClient
endpoint = "https://<my-custom-subdomain>.cognitiveservices.azure.com/"
credential = AzureKeyCredential("<api-key>")
client = ConversationAnalysisClient(endpoint, credential)
Create ConversationAuthoringClient
Once you've determined your endpoint and API key you can instantiate a ConversationAuthoringClient:
from azure.core.credentials import AzureKeyCredential
from azure.ai.language.conversations.authoring import ConversationAuthoringClient
endpoint = "https://<my-custom-subdomain>.cognitiveservices.azure.com/"
credential = AzureKeyCredential("<api-key>")
client = ConversationAuthoringClient(endpoint, credential)
Create a client with an Azure Active Directory Credential
To use an Azure Active Directory (AAD) token credential,
provide an instance of the desired credential type obtained from the
azure-identity library.
Note that regional endpoints do not support AAD authentication. Create a custom subdomain
name for your resource in order to use this type of authentication.
Authentication with AAD requires some initial setup:
Install azure-identity
Register a new AAD application
Grant access to the Language service by assigning the "Cognitive Services Language Reader" role to your service principal.
After setup, you can choose which type of credential from azure.identity to use.
As an example, DefaultAzureCredential
can be used to authenticate the client:
Set the values of the client ID, tenant ID, and client secret of the AAD application as environment variables:
AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_SECRET
Use the returned token credential to authenticate the client:
from azure.ai.language.conversations import ConversationAnalysisClient
from azure.identity import DefaultAzureCredential
credential = DefaultAzureCredential()
client = ConversationAnalysisClient(endpoint="https://<my-custom-subdomain>.cognitiveservices.azure.com/", credential=credential)
Key concepts
ConversationAnalysisClient
The ConversationAnalysisClient is the primary interface for making predictions using your deployed Conversations models. For asynchronous operations, an async ConversationAnalysisClient is in the azure.ai.language.conversation.aio namespace.
ConversationAuthoringClient
You can use the ConversationAuthoringClient to interface with the Azure Language Portal to carry out authoring operations on your language resource/project. For example, you can use it to create a project, populate with training data, train, test, and deploy. For asynchronous operations, an async ConversationAuthoringClient is in the azure.ai.language.conversation.authoring.aio namespace.
Examples
The azure-ai-language-conversation client library provides both synchronous and asynchronous APIs.
The following examples show common scenarios using the client created above.
Analyze Text with a Conversation App
If you would like to extract custom intents and entities from a user utterance, you can call the client.analyze_conversation() method with your conversation's project name as follows:
# import libraries
import os
from azure.core.credentials import AzureKeyCredential
from azure.ai.language.conversations import ConversationAnalysisClient
# get secrets
clu_endpoint = os.environ["AZURE_CONVERSATIONS_ENDPOINT"]
clu_key = os.environ["AZURE_CONVERSATIONS_KEY"]
project_name = os.environ["AZURE_CONVERSATIONS_PROJECT_NAME"]
deployment_name = os.environ["AZURE_CONVERSATIONS_DEPLOYMENT_NAME"]
# analyze quey
client = ConversationAnalysisClient(clu_endpoint, AzureKeyCredential(clu_key))
with client:
query = "Send an email to Carol about the tomorrow's demo"
result = client.analyze_conversation(
task={
"kind": "Conversation",
"analysisInput": {
"conversationItem": {
"participantId": "1",
"id": "1",
"modality": "text",
"language": "en",
"text": query
},
"isLoggingEnabled": False
},
"parameters": {
"projectName": project_name,
"deploymentName": deployment_name,
"verbose": True
}
}
)
# view result
print("query: {}".format(result["result"]["query"]))
print("project kind: {}\n".format(result["result"]["prediction"]["projectKind"]))
print("top intent: {}".format(result["result"]["prediction"]["topIntent"]))
print("category: {}".format(result["result"]["prediction"]["intents"][0]["category"]))
print("confidence score: {}\n".format(result["result"]["prediction"]["intents"][0]["confidenceScore"]))
print("entities:")
for entity in result["result"]["prediction"]["entities"]:
print("\ncategory: {}".format(entity["category"]))
print("text: {}".format(entity["text"]))
print("confidence score: {}".format(entity["confidenceScore"]))
if "resolutions" in entity:
print("resolutions")
for resolution in entity["resolutions"]:
print("kind: {}".format(resolution["resolutionKind"]))
print("value: {}".format(resolution["value"]))
if "extraInformation" in entity:
print("extra info")
for data in entity["extraInformation"]:
print("kind: {}".format(data["extraInformationKind"]))
if data["extraInformationKind"] == "ListKey":
print("key: {}".format(data["key"]))
if data["extraInformationKind"] == "EntitySubtype":
print("value: {}".format(data["value"]))
Analyze Text with an Orchestration App
If you would like to pass the user utterance to your orchestrator (worflow) app, you can call the client.analyze_conversation() method with your orchestration's project name. The orchestrator project simply orchestrates the submitted user utterance between your language apps (Luis, Conversation, and Question Answering) to get the best response according to the user intent. See the next example:
# import libraries
import os
from azure.core.credentials import AzureKeyCredential
from azure.ai.language.conversations import ConversationAnalysisClient
# get secrets
clu_endpoint = os.environ["AZURE_CONVERSATIONS_ENDPOINT"]
clu_key = os.environ["AZURE_CONVERSATIONS_KEY"]
project_name = os.environ["AZURE_CONVERSATIONS_WORKFLOW_PROJECT_NAME"]
deployment_name = os.environ["AZURE_CONVERSATIONS_WORKFLOW_DEPLOYMENT_NAME"]
# analyze query
client = ConversationAnalysisClient(clu_endpoint, AzureKeyCredential(clu_key))
with client:
query = "Reserve a table for 2 at the Italian restaurant"
result = client.analyze_conversation(
task={
"kind": "Conversation",
"analysisInput": {
"conversationItem": {
"participantId": "1",
"id": "1",
"modality": "text",
"language": "en",
"text": query
},
"isLoggingEnabled": False
},
"parameters": {
"projectName": project_name,
"deploymentName": deployment_name,
"verbose": True
}
}
)
# view result
print("query: {}".format(result["result"]["query"]))
print("project kind: {}\n".format(result["result"]["prediction"]["projectKind"]))
# top intent
top_intent = result["result"]["prediction"]["topIntent"]
print("top intent: {}".format(top_intent))
top_intent_object = result["result"]["prediction"]["intents"][top_intent]
print("confidence score: {}".format(top_intent_object["confidenceScore"]))
print("project kind: {}".format(top_intent_object["targetProjectKind"]))
if top_intent_object["targetProjectKind"] == "Luis":
print("\nluis response:")
luis_response = top_intent_object["result"]["prediction"]
print("top intent: {}".format(luis_response["topIntent"]))
print("\nentities:")
for entity in luis_response["entities"]:
print("\n{}".format(entity))
Conversational Summarization
You can use this sample if you need to summarize a conversation in the form of an issue, and final resolution. For example, a dialog from tech support:
# import libraries
import os
from azure.core.credentials import AzureKeyCredential
from azure.ai.language.conversations import ConversationAnalysisClient
# get secrets
endpoint = os.environ["AZURE_CONVERSATIONS_ENDPOINT"]
key = os.environ["AZURE_CONVERSATIONS_KEY"]
# analyze query
client = ConversationAnalysisClient(endpoint, AzureKeyCredential(key))
with client:
poller = client.begin_conversation_analysis(
task={
"displayName": "Analyze conversations from xxx",
"analysisInput": {
"conversations": [
{
"conversationItems": [
{
"text": "Hello, how can I help you?",
"modality": "text",
"id": "1",
"participantId": "Agent"
},
{
"text": "How to upgrade Office? I am getting error messages the whole day.",
"modality": "text",
"id": "2",
"participantId": "Customer"
},
{
"text": "Press the upgrade button please. Then sign in and follow the instructions.",
"modality": "text",
"id": "3",
"participantId": "Agent"
}
],
"modality": "text",
"id": "conversation1",
"language": "en"
},
]
},
"tasks": [
{
"taskName": "Issue task",
"kind": "ConversationalSummarizationTask",
"parameters": {
"summaryAspects": ["issue"]
}
},
{
"taskName": "Resolution task",
"kind": "ConversationalSummarizationTask",
"parameters": {
"summaryAspects": ["resolution"]
}
},
]
}
)
# view result
result = poller.result()
task_results = result["tasks"]["items"]
for task in task_results:
print(f"\n{task['taskName']} status: {task['status']}")
task_result = task["results"]
if task_result["errors"]:
print("... errors occurred ...")
for error in task_result["errors"]:
print(error)
else:
conversation_result = task_result["conversations"][0]
if conversation_result["warnings"]:
print("... view warnings ...")
for warning in conversation_result["warnings"]:
print(warning)
else:
summaries = conversation_result["summaries"]
print("... view task result ...")
for summary in summaries:
print(f"{summary['aspect']}: {summary['text']}")
Import a Conversation Project
This sample shows a common scenario for the authoring part of the SDK
import os
from azure.core.credentials import AzureKeyCredential
from azure.ai.language.conversations.authoring import ConversationAuthoringClient
clu_endpoint = os.environ["AZURE_CONVERSATIONS_ENDPOINT"]
clu_key = os.environ["AZURE_CONVERSATIONS_KEY"]
project_name = "test_project"
exported_project_assets = {
"projectKind": "Conversation",
"intents": [{"category": "Read"}, {"category": "Delete"}],
"entities": [{"category": "Sender"}],
"utterances": [
{
"text": "Open Blake's email",
"dataset": "Train",
"intent": "Read",
"entities": [{"category": "Sender", "offset": 5, "length": 5}],
},
{
"text": "Delete last email",
"language": "en-gb",
"dataset": "Test",
"intent": "Delete",
"entities": [],
},
],
}
client = ConversationAuthoringClient(
clu_endpoint, AzureKeyCredential(clu_key)
)
poller = client.begin_import_project(
project_name=project_name,
project={
"assets": exported_project_assets,
"metadata": {
"projectKind": "Conversation",
"settings": {"confidenceThreshold": 0.7},
"projectName": "EmailApp",
"multilingual": True,
"description": "Trying out CLU",
"language": "en-us",
},
"projectFileVersion": "2022-05-01",
},
)
response = poller.result()
print(response)
Optional Configuration
Optional keyword arguments can be passed in at the client and per-operation level. The azure-core reference documentation describes available configurations for retries, logging, transport protocols, and more.
Troubleshooting
General
The Conversations client will raise exceptions defined in Azure Core.
Logging
This library uses the standard
logging library for logging.
Basic information about HTTP sessions (URLs, headers, etc.) is logged at INFO
level.
Detailed DEBUG level logging, including request/response bodies and unredacted
headers, can be enabled on a client with the logging_enable argument.
See full SDK logging documentation with examples here.
import sys
import logging
from azure.core.credentials import AzureKeyCredential
from azure.ai.language.conversations import ConversationAnalysisClient
# Create a logger for the 'azure' SDK
logger = logging.getLogger('azure')
logger.setLevel(logging.DEBUG)
# Configure a console output
handler = logging.StreamHandler(stream=sys.stdout)
logger.addHandler(handler)
endpoint = "https://<my-custom-subdomain>.cognitiveservices.azure.com/"
credential = AzureKeyCredential("<my-api-key>")
# This client will log detailed information about its HTTP sessions, at DEBUG level
client = ConversationAnalysisClient(endpoint, credential, logging_enable=True)
result = client.analyze_conversation(...)
Similarly, logging_enable can enable detailed logging for a single operation, even when it isn't enabled for the client:
result = client.analyze_conversation(..., logging_enable=True)
