How Walmart drives innovation for their conversational AI and LLM applications

Walmart wanted to enhance the efficiency of generating labeled data for its conversational AI and large language model (LLM) applications. Their data science team aimed to streamline the annotation of conversational text from shopping chatbots and the labeling of inventory images for object detection and classification models, encompassing a vast array of diverse product SKUs. The application of labels to conversations would bolster the retailer's conversational AI models, leading to more natural interactions and increased customer satisfaction. Labelbox provided an end-to-end, in-app labeling workflow tailored to conversational AI needs. In terms of ROI, the company reported a 25% increase in data accuracy, along with a 25% reduction in turnaround time for model development.
