Abstract
An information-seeking dialogue system can be trained using a pipeline process having stages, or components, of passage retrieval (selecting passages relevant to a query from a corpus or knowledge base), re-ranking, and generating a response to the query based on one or more of the re-ranked passages. Each stage, or component, of the pipeline can be individually optimized based on ground truth data.
