Electronic acquisition of troubleshooting knowledge for medical imaging scanners

A computer-implemented method, comprising:

• accessing, by a device operatively coupled to a processor, a plain text service manual and a service complaint that are associated with a medical imaging scanner;
• identifying, by the device and via named-entity recognition or natural language processing, a semantic hierarchy of the plain text service manual;
• and
• recording, by the device and via graphical user interface tracking, how a service technician that is troubleshooting the service complaint sequentially navigates through the semantic hierarchy, thereby yielding a troubleshooting trace that corresponds to the service complaint.

A computer program product for facilitating electronic acquisition of troubleshooting knowledge, the computer program product comprising a non-transitory computer-readable memory having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• access one or more plain text documents associated with a machine;
• identify, via named-entity recognition or natural language processing, a semantic hierarchy of the one or more plain text documents;
• record, via graphical user interface tracking, how a service technician that is troubleshooting a service complaint associated with the machine sequentially navigates through the semantic hierarchy, thereby yielding a troubleshooting trace that corresponds to the service complaint;
• and
• train a deep learning neural network on the service complaint and on the troubleshooting trace, with the service complaint being a training input, and with the troubleshooting trace being a ground-truth annotation.
