Systems and methods for providing inquiry responses using linguistics and machine learning

A system for automatically providing solutions to user questions relating to an operation of an industrial machine, the system comprising:

• a linguistic module that executes on a computer to extract keywords from a question text relating to an operation of an industrial machine, lookup a first plurality of solutions from a knowledge base that match said keywords, and assign each of the first plurality of solutions with a first score based on a number or a frequency of matching keywords in a text of the solution;
• a machine learning module that executes on the computer to provide a predictive model trained on previous diagnostic data and corresponding solutions relating to the operation of other industrial machines, use the predictive model to predict a second plurality of solutions based on non-textual diagnostic data generated by the industrial machine, and assign each of the second plurality of solutions with a second score based on a model probability associated with the solution, wherein the non-textual diagnostic data represents at least a current state of the industrial machine, and
• a combination module that executes on the computer to combine the first plurality of solutions and the second plurality of solutions in a ranked order determined by the first score and the second score of each solution.
