Patent ID: 11928160
Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A classification device comprising:
processing circuitry configured to:
obtain operation logs describing operation content for a window on a terminal screen;
for each operation log of the obtained operation logs, generate a vector using words from the operation content for the operation log;
classify, using a document classification method, a label to each group of a plurality of groups by (i) identifying a first frequency with which a word from a respective generated vector appears in a first subset of other generated vectors that satisfies a threshold and (ii) identifying a second frequency with which the word appears in a second subset of the other generated vectors that does not satisfy the threshold, the first subset being different form the second subset; and
cause an output device to output the labeled operation logs to a display.
