Classification device, classification method, and classification program
View Patent ↗A classification device includes processing circuitry configured to obtain operation logs describing operation content for a window on a terminal screen, classify the operation logs into a plurality of groups, using a document classification method, based on the operation content of the operation logs, and assign words characteristic of respective groups as labels to these groups, and cause an output device to output the operation logs assigned the labels.
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.
2. The classification device according to claim 1 , wherein the processing circuitry is further configured to convert the operation content of the operation logs assigned a same label into a flowchart of items of the operation content arranged in a processing order, or convert items of the operation content described in the operation logs into a chart obtained by aggregating with respect to the label.
3. A classification method executed by a classification device, comprising:
obtaining operation logs describing operation content for a window on a terminal screen;
for each operation log of the obtained operation logs, generating a vector using words from the operation content for the operation log;
classifying, 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
causing an output device to output the labeled operation logs to a display.
4. A non-transitory computer-readable recording medium storing therein a classification program that causes a computer to execute a process comprising:
obtaining operation logs describing operation content for a window on a terminal screen;
for each operation log of the obtained operation logs, generating a vector using words from the operation content for the operation log;
classifying, 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
causing an output device to output the labeled operation logs to a display.
