Query: AliMe MKG: A Multi-modal Knowledge Graph for Live-streaming E-commerce   Live streaming is becoming an increasingly popular trend of sales in
E-commerce. The core of live-streaming sales is to encourage customers to
purchase in an online broadcasting room. To enable customers to better
understand a product without jumping out, we propose AliMe MKG, a multi-modal
knowledge graph that aims at providing a cognitive profile for products,
through which customers are able to seek information about and understand a
product. Based on the MKG, we build an online live assistant that highlights
product search, product exhibition and question answering, allowing customers
to skim over item list, view item details, and ask item-related questions. Our
system has been launched online in the Taobao app, and currently serves
hundreds of thousands of customers per day.
