Caller and callee intent recognition for telesales

Service activation and resource plan purchase

Before you start, ensure that the service is activated. After activation, you must purchase a resource plan.

• Service activation: Activation page

• Resource plan purchase: Purchase page

Service invocation and testing

For more information about how to invoke the model, see Model invocation.

For software development kit (SDK) examples, see SDK examples.

Configure access credentials (AKSK) using environment variables

1. Notes:

   1. An AccessKey pair for an Alibaba Cloud account has permissions to access all APIs. This poses a high security threat. For better security, we recommend that you create and use a Resource Access Management (RAM) user to make API calls or perform routine O&M. To create a RAM user, log on to the RAM console.

   2. Do not hard-code your AccessKey ID and AccessKey secret in your code. This practice poses a security risk if the keys are leaked. Instead, store your AccessKey pair in environment variables.

2. Configuration for Linux and macOS

   export NLP_AK_ENV=<access_key_id>
   export NLP_SK_ENV=<access_key_secret>

   Replace <access_key_id> with your AccessKey ID and <access_key_secret> with your AccessKey secret. For more information about how to obtain an AccessKey ID and an AccessKey secret, see Step 2: Obtain an AccessKey pair.

3. Configuration method for Windows

   1. Create a file for the environment variables. In the file, add the NLP_AK_ENV environment variable for your AccessKey ID and the NLP_SK_ENV environment variable for your AccessKey secret.

   2. Restart your Windows system.

Java code example

class MsgDO{
            private String role;
            private String words;
            public MsgDO(String role,String words) {
                this.role = role;
                this.words = words;
            }
            public String getRole() {
                return role;
            }
            public void setRole(String role) {
                this.role = role;
            }
            public String getWords() {
                return words;
            }
            public void setWords(String words) {
                this.words = words;
            }
        }

* An AccessKey for an Alibaba Cloud account provides full access to all APIs and poses a high security risk. We strongly recommend that you log on to the RAM console to create and use a RAM user for API access or daily operations and maintenance (O&M).

* This example stores the AccessKey and AccessKey secret in an environment variable. Alternatively, you can store them in a configuration file to suit your business needs.

* We strongly recommend that you do not embed your AccessKey and AccessKey secret in your code to avoid the security risk of key leakage.
