Determining repair status information to provide in response to queries with associated source tracking and confidence data

Abstract

Techniques are described for performing automated operations related to identifying and using repair and maintenance status information for devices and/or other items or entities, such as summarizing and encoding incoming data, identifying specific encoded information in response to natural language queries, and using the identified repair and maintenance status information in further automated manners in some situations (e.g., to automatically initiate repair or maintenance actions on a particular computing device), along with determining, tracking and providing information about source(s) of data elements stored in the database, and determining, storing and providing information about confidence levels in current accuracy of associated stored data elements. For example, source information tracking may include generating and using a source tracking graph with nodes and edges representing the processing and data flow of incoming data as part of its categorization and encoding into groups of related data items of multiple types.
