Overview

The “Gen AI for E-commerce” workshop explores the role of Generative Artificial Intelligence in transforming e-commerce through enhanced user experience and operational efficiency. E-commerce companies grapple with multiple challenges such as lack of quality content for products, subpar user experience, sparse datasets etc. Gen AI offers significant potential to address these complexities. Yet, deploying these technologies at scale presents challenges such as hallucination in data, excessive costs, increased latency response, and limited generalization in sparse data environments. This workshop will bring together experts from academia and industry to discuss these challenges and opportunities, aiming to showcase case studies, breakthroughs, and insights into practical implementations of Gen AI in e-commerce.

Call for papers

We will welcome papers that leverage Generative Artificial Intelligence (Gen AI) in e-commerce. Detailed topics are mentioned in CFP. Papers can be submitted at Easychair.

From Search to Conversational Shopping with Generative AI

Abstract
Abstract: The rapid growth of online shopping platforms such as Amazon has brought services to billions of people worldwide. With global retail sales surpassing $6 trillion in 2024 and is trending increase in 2025, customer expectations for personalized and seamless shopping experiences have never been higher. In this talk, I will share our multi years journey of reimagining online shopping at Amazon—transforming it from a product search problem into a conversational shopping experience powered by generative models. Specifically, I will cover: (1) How the product search engine traditionally worked. (2) How we began adopting conversational shopping and use language models for this new paradigm. (3) How we are building shopping agents that empower customers with richer, more personalized experiences.

  • Mind the Gap: Bridging Behavioral Silos with LLMs in Multi-Vertical Recommendations
    Nimesh Sinha, Raghav Saboo, Martin Wang, Sudeep Das
    Abstract
    Abstract: In multi-vertical e-commerce platforms like DoorDash, relatively newer product verticals such as grocery and retail present a significant opportunity for personalization innovation. A key challenge lies in solving the "cold start" problem for users. This paper introduces a novel framework for enhancing recommendation quality by transferring knowledge from data-rich verticals (e.g., restaurants at DoorDash) to data-sparse ones. We leverage Large Language Models (LLMs) to perform generative inference, synthesizing sparse, high-dimensional features that encapsulate user preferences across different verticals.

  • CRMAgent: A Multi-Agent LLM System for E-Commerce CRM Message Template Generation
    Yinzhu Quan, Xinrui Li, Ying Chen
    Abstract
    Abstract: In e-commerce private-domain channels such as instant messaging and e-mail, merchants engage customers directly as part of their Customer Relationship Management (CRM) programmes to drive retention and conversion. While a few top performers excel at crafting outbound messages, most merchants struggle to write per- suasive copy because they lack both expertise and scalable tools. We introduce CRMAgent, a multi-agent system built on large language models (LLMs) that generates high-quality message templates and actionable writing guidance through three complementary modes. First, group-based learning enables the agent to learn from a merchant’s own top-performing messages within the same audience segment and rewrite low-performing ones. Second, retrieval-and- adaptation fetches templates that share the same audience segment and exhibit high similarity in voucher type and product category, learns their successful patterns, and adapts them to the current cam-paign. Third, a rule-based fallback provides a lightweight zero-shot rewrite when no suitable references are available. Extensive experi- ments show that CRMAgent consistently outperforms merchants’ original templates, delivering significant gains in both audience- match and marketing-effectiveness metrics.
