Abstract: Techniques are described for performing automated operations related to identifying and using repair and maintenance information, such as extracting and linking data about repair and maintenance activities performed on various devices or other entities, determining specific repair and/or maintenance information of one or more specified types in response to queries (e.g., for one or more particular such devices that are identified based on those queries), and subsequently using the identified repair information in further automated manners in some situations (e.g., to automatically initiate repair or maintenance actions on a particular target computing device). The extracting of repair and maintenance data may include analyzing information from multiple source documents (from one or more repair activity providers) and/or across multiple repair encounters, and using a combination of both image-based and text-based analyses.
