Product review analysis service for the E-commerce realm-Natural Language Processing(NLP)-阿里云帮助中心

The product review analysis service parses product reviews in the E-commerce realm.

This document describes how to use the product review analysis service for the E-commerce realm. If the currently supported realms and industries do not meet your needs, you can join the NLP Self-learning Platform Q&A DingTalk group 2 (Group ID: 44619071) to discuss collaboration.

Note

This service is provided by the NLP Self-learning Platform. You can use it by directly calling the API.

Service activation and resource plan purchase

Before using the service, confirm that it is activated. After activation, purchase a resource plan.

Activate service: Activation URL
Purchase resource plan: Purchase URL

Service invocation and debugging

For more information about model invocation, see Model invocation.

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

Debug

You can run this API operation directly in the OpenAPI Developer Portal to avoid calculating a signature. After the operation runs successfully, the OpenAPI Developer Portal automatically generates SDK sample code.

Configure access credentials (AKSK) using environment variables

Notes:
1. An AccessKey for an Alibaba Cloud account has all API access permissions. This poses a high security risk. We recommend that you create and use a Resource Access Management (RAM) user for API access or daily operations and maintenance (O&M). To create a RAM user, log on to the RAM console.
2. Do not hardcode your AccessKey ID and AccessKey secret in your code. Doing so can lead to key leakage. Instead, configure environment variables to store and access your AccessKey ID and AccessKey secret.
Configuration for Linux and macOS systems
```
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 for your account.
Configuration for Windows systems
1. Create a file for the environment variables. Add the environment variables NLP_AK_ENV and NLP_SK_ENV and set their values to your AccessKey ID and AccessKey secret.
2. Restart the Windows system.

To call the product review analysis service for the E-commerce realm, set ServiceName to ReviewAnalysis.
