System and method for improved spare part search for maintenance services using topic modelling

摘要: A recommendation method (200) includes: querying a knowledge base (130) of maintenance cases using the text query to retrieve a ranked list (138) of maintenance cases relating to a text query; performing topic modeling (140) on the maintenance cases of the ranked list of maintenance cases to group the maintenance cases into N topics; 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 (142) for that topic; displaying summarization (144) 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 (150) 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.
