Research on Building a Vertical AI Foundation for Automotive Digital Marketing with Open-Source Large Models
As the automotive industry transitions from "incremental expansion" to "deepening existing markets," digital marketing is emerging as a critical battleground for cost reduction and efficiency enhancement. This study focuses on the "platform AI large model foundation" system, exploring how to integrate open-source large models with domain-specific automotive datasets to train vertical models tailored for digital marketing scenarios in the automotive sector, thereby supporting core capabilities such as semantic understanding and content generation. The research constructs a specialized automotive marketing corpus covering vehicle analysis, competitive benchmarking, user profiling, and marketing messaging. It proposes a dual-model training architecture combining LoRA-based parameter-efficient fine-tuning and RAG (Retrieval-Augmented Generation), and integrates knowledge graphs into the marketing decision-making pipeline. This work provides a practical technical foundation and systematic methodology for the intelligent transformation of digital marketing in the automotive industry.
