Abstract

Systems and methods for selecting types of generated prompts for further data from a user in a multi-turn interactive dialog. In one scenario, a processed sequence of user inputs and machine-generated prompts improves searches for the most relevant items available for purchase in an electronic marketplace. The number of prompts may be limited to a predetermined maximum value. Prompt generation is minimized by incorporating into a knowledge graph world knowledge that helps user intent inference. Prompt generation may be suppressed if a search indicates the reply to a prompt will not lead to any satisfactory search results. Prompts can provide suggestions for available search results that either meet all query constraints, or meet only some query constraints if a search indicates no search results are available that meet all query constraints. Prompts can provide suggested incisive reply phrasing likely to improve search results through an affirmation or negation reply.
