Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 8:
9. A computing system, comprising:
a processor;
a memory device coupled to the processor; and
a computer readable storage device coupled to the processor, wherein the storage device contains program code executable by the processor via the memory device to implement a method comprising:
determining, by the processor, a key position of a key in an electronic file;
isolating, by the processor, candidate key values based on a distance from the key position measured in at least three directions, wherein the isolating includes:
searching for candidate bounding boxes that contain the candidate key values based on the distance from the key position, and
filtering the candidate bounding boxes based on a relative position of a candidate bounding box with respect to the key position and other candidate bounding boxes;

selecting, by the processor, a key value from the candidate key values based on an output of a trained neural network; and
extracting, by the processor, the key and the key value from the electronic file.
