On-Device Content-Specific Model Orchestration for Optimizing User-Generated Content

User-generated content can be obtained from a user of a mapping application executed by the user computing device, wherein the user-generated content is associated with a particular Point of Interest (POI). A content-specific machine-learned model can be selected based on the user-generated content and/or a set of contextual information. The set of contextual information includes a location of the particular POI, information descriptive of the particular POI, and/or information descriptive of the user-generated content. The user-generated content can be processed with the first content-specific machine-learned model to obtain a quality metric. Based on the quality metric a determination can be made whether to provide the user-generated content to a server computing system associated with the mapping application.
