• generating a vector representation for each unhandled query in a set of unhandled queries, each unhandled query comprising an interaction between a user and a virtual agent in which the virtual agent did not select a correspondence topic;
• clustering the vector representations for the set of unhandled queries to generate a plurality of clusters of vector representations, each cluster corresponding to a group of unhandled queries;
• and
• providing a suggested topic corresponding to one of the clusters to an authoring tool that comprises an interactive element to add the suggested topic to a set of topics implemented in the virtual agent,
• wherein a selection of the interaction element configures the virtual agent to access the set of topics that includes the suggested topic in a future conversation involving the virtual agent.
