lack a unified search platform that integrates all products and allows existing products to quickly onboard. Therefore, we are committed to: • Integrating LINE's diverse internal assets to build a unified search platform. • Combining advanced technologies and algorithms to optimize the search experience. 2 Search Engine in LINE Search in LINE
are also dedicated to research in Retrieval- Augmented Generation (RAG), expanding search effectiveness through embedding-based retrieval approaches. With the increasing diversity of data across LINE products, we have begun researching multimodal RAG and more flexible agent-based search engines.

build their own text-to-image / image-to-image search service and object detection service • For image search service, we leverage CLIP model to perform semantic search • For object detection service, we leverage YOLO v9 model to detect the bounding box of the objects in the image and identify their categories 5 Vision Language Search - Image Search Vision Language Search Image-to-Image Query nature and lifestyle photography text-to-Image Query
In LINE Shopping, we integrate services such as OpenSearch and Airflow to build a comprehensive data pipeline for the product. This system embeds millions of images into vectors through CLIP models, enabling users to instantly find the most similar items through vector-based search in real-time. Additionally, we leverage text-based techniques and utilize object detection as an information extraction model to filter out excessive noise, resulting in more accurate prediction results.
