Automated Topic Exploration

A computing system comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable media that collectively store instructions that, when executed by the one or more processors, cause the computing system to perform operations, the operations comprising:
• receiving, by the computing system, a request to initiate an automated topic exploration;
• in response to the request, processing, by the computing system, a model input with a machine-learned topic generation model to generate a topic statement as an output of the machine-learned topic generation model;
• generating, by the computing system, a plurality of information retrieval queries that query for source documents related to the topic statement;
• causing, by the computing system, the plurality of information retrieval queries to be executed on one or more information retrieval systems to return a plurality of candidate source documents that are responsive to the plurality of information retrieval queries;
• and
• collecting, by the computing system at least a subset of the plurality of candidate source documents into a proposed set of source documents.
