Method and apparatus for automated creation of search patterns

A method for automated problem solving with a search pattern dataset based on entries in a knowledge database in which stored log passages of a protocol file of a device system are linked to at least one of problem analyses or problem solutions, the method comprising:

• training a machine learning model using at least a training dataset including a search pattern dataset;
• and
• creating the search pattern dataset, wherein the creating the search pattern dataset includes,
• a) loading an entry from the knowledge database, the entry including at least one of explanatory text, images, and protocol files, and creating a search text from the entry, the entry corresponding to a problem in an imaging system;
• b) identifying a log passage in the search text, the search text associated with text of the protocol file;
• c) testing whether the identified log passage is relevant;
• d) storing the log passage if the identified log passage is relevant or repeating steps b) and c) and identifying and checking a further log passage until no further log passage can be identified if the identified log passage is not relevant;
• e) indicating a linkage of log passages in response to a text that adjoins the identified log passage in the search text;
• f) storing the linkage together with a statement regarding to which log passages the linkage relates;
• g) repeating the steps b) to f) with further log passages until a termination condition is reached;
• h) generating a search pattern based on the stored log passages and stored linkages after reaching the termination condition wherein the search pattern corresponds to a ground truth based on a problem described in an entry, wherein the ground truth includes the problem in the imaging system and a solution to the problem in the imaging system;
• and
• i) repeating the steps a) to h) for a plurality of entries in the knowledge database, wherein the search pattern dataset comprises the plurality of search patterns and the plurality of corresponding ground truths.
