LLMs enhance e-commerce ad relevance evaluation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new metric for evaluating dynamic product advertising (DPA) retrieval systems in e-commerce. This metric compresses user engagement history into intent representatives and then assesses product relevance to these intents, providing a stable user-level relevance score. Large language models (LLMs) are utilized as semantic relevance judges within an agentic prompting framework to capture nuanced relationships, enabling more efficient and reliable iteration of DPA systems before costly A/B testing.

    LLM-based User-Product Relevance Evaluation for Dynamic Product Advertising

    Dynamic Product Advertising (DPA) retrieval systems are a core component of modern e-commerce advertising; however, their evaluation remains challenging. Conventional offline engagement metrics are limited by sparse, biased feedback, while online evaluation is costly and time-con…
