Abstract: Embodiments of the present disclosure provide a method and a device for processing natural language. The method comprises obtaining a set of terms corresponding to an initial input sentence to be processed, wherein the set of terms comprises initial terms included in the initial input sentence and extended terms of the initial terms; performing word order restoring on terms in the set of terms to obtain an extended sentence of the initial input sentence; and obtaining a processing result based on the extended sentence and a Natural Language Process (NLP) model.

Abstract: The disclosed embodiments provide a system for performing unified management of targeting attributes in A/B tests. During operation, the system obtains attribute configurations for attributes to be used in subsequent targeting of users by A/B tests. Next, the system configures, based on the attribute configurations, onboarding of the attributes from an offline environment, a near-real-time environment, and an online environment. During an A/B test, the system retrieves values of one or more of the attributes for a user from locations specified in the attribute configurations. Finally, the system outputs the values with targeting conditions for the A/B test for use in selecting a treatment assignment for the user in the A/B test.
