1. A medical parts ordering system operative in conjunction with a knowledge base of maintenance cases for medical devices under maintenance wherein the maintenance cases have associated replaced part identifiers, the medical parts ordering system comprising:
a user interface device including a display and at least one user input device;
a knowledge base of maintenance cases for medical devices, wherein the knowledge base includes information about the medical device of the corresponding maintenance case, wherein the information includes information securely transferred from the medical device to knowledge base and is correlated to the solution of the maintenance case; and
an electronic processor programmed to perform a recommendation method for recommending parts for replacement during maintenance of a device currently under maintenance, the recommendation method including:
receiving a text query relating to the maintenance of the device currently under maintenance via the user interface device;
querying the knowledge base of maintenance cases using the text query to compare against the maintenance case and information received from the corresponding medical device of the maintenance case to retrieve a ranked list of maintenance cases relating to the text query;
performing topic modeling on the maintenance cases of the ranked list of maintenance cases to group the maintenance cases into N topics, where N is an integer greater than or equal to two;
for each topic, ranking the replaced part identifiers associated to the maintenance cases grouped into that topic to generate a ranked replaced part identifiers list for that topic;
displaying summarizations of the N topics on the display of the user interface and receiving a selection of a selected topic of the N topics via the user interface device; and
displaying a list of recommended parts for replacement comprising at least a top portion of the ranked replaced part identifiers list for the selected topic on the display of the user interface device, wherein the displaying of the list of recommended parts for replacement is included in a parts ordering user interface presented on the user interface device, and the electronic processor is further programmed to:
receive a selection of one or more part identifiers via the parts ordering user interface and to connect via an electronic network with a parts ordering system to order one or more parts corresponding to the selected one or more part identifiers.
