使用大型语言模型构建DoorDash的产品知识图谱

DoorDash’s retail catalog is a centralized dataset of essential product information for all products sold by new verticals merchants – merchants operating a business other than a restaurant, such as a grocery, a convenience store, or a liquor store. Within the retail catalog, each SKU, or stock keeping unit, is represented by a list of product attributes. Figure 1 shows an example SKU and some of its attributes as it is stored in the retail catalog.

DoorDash的零售目录是一个集中的数据集，包含所有新垂直商家销售的产品的基本信息，这些商家经营的业务不限于餐厅，例如杂货店、便利店或酒类店。在零售目录中，每个SKU（库存单位）由一系列产品属性表示。图1显示了一个示例SKU及其在零售目录中存储的一些属性。

When a merchant comes onboard at DoorDash, we add their internal SKU data — raw merchant data — to our retail catalog. SKU data from different merchants come in varying formats and quality; they may, for example, have missing or incorrect attribute values.
