Abstract
Disclosed are a device and a method for restoring missing operational data. The method for restoring missing operational data includes determining whether missing data is present in a first event defining operational data or a first resource constituting the operational data, extracting candidate data from a missing table, depending on a form in which the first resource is defined by the first event and a location where the missing data is identified, and processing the candidate data to restore the missing data, based on a predetermined restoration scheme.
Claims18
A method for restoring missing operational data, the method comprising:
- determining which one of three locations missing data is identified in, wherein the three locations are 1) a first event in a header area of operational data, 2) a first resource in the body area of the operational data, and 3) both the first event and the first resource, wherein the first even is activity using the first resource;
- determining which one of four forms related to number of the first resource and the first event, wherein the four forms are 1) a form in which the first resource is provided in singular and the first event is provided in singular, 2) a form in which the first resource is provided in singular and the first event is provided in plural, 3) a form in which the first resource is provided in plural and the first event is provided in singular, and 4) a form in which the first resource is provided in plural and the first event is provided in plural;
- extracting candidate data from a missing table, depending on a combination of 1) the determined form of the four forms related to the number of the first resource and the first event and 2) the determined location where the missing data is identified;
- and
- processing the candidate data to restore the missing data, based on at least one restoration scheme selected from three restoration schemes, wherein the three restoration schemes are 1) a scheme of comparing one or more events or one or more resources in operational data and non-missing operational data one-to-one and assigning scores depending on a degree of coincidence to determine candidate data to be restored, 2) a scheme for determining the candidate data to be restored through an event chain according to an order in which unit events are arranged, and 3) a scheme for determining the candidate data to be restored through a solution set composed of unit resources,
- wherein the at least one restoration scheme is selected based on the combination of 1) the determined form of the four forms related to the number of the first resource and the first event and 2) the determined location where the missing data is identified.

A restoration device of missing operational data, the device comprising:
- a check processor configured to determine which one of three locations missing data is identified in, wherein the three locations are 1) a first event in a header area of operational data, 2) a first resource in a body area of the operational data, and 3) both the first event and the first resource, and configured to determine which one of four forms related to number of the first resource and the first event, wherein the four forms are 1) a form in which the first resource is provided in singular and the first event is provided in singular, 2) a form in which the first resource is provided in singular and the first event is provided in plural, 3) a form in which the first resource is provided in plural and the first event is provided in singular, and 4) a form in which the first resource is provided in plural and the first event is provided in plural;
- an extraction processor configured to extract candidate data from a missing table, depending on a combination of 1) the determined form related to the number of the first resource and the first event and 2) the determined location where the missing data is identified;
- and
- a restoration processor configured to process the candidate data to restore the missing data, based on at least one restoration scheme selected from three restoration schemes, wherein the three restoration schemes are 1) a scheme of comparing one or more events or one or more resources in operational data and non-missing operational data one-to-one and assigning scores depending on a degree of coincidence to determine candidate data to be restored, 2) a scheme for determining the candidate data to be restored through an event chain according to an order in which unit events are arranged, and 3) a scheme for determining the candidate data to be restored through a solution set composed of unit resources,
- wherein the at least one restoration scheme is selected based on the combination of 1) the determined form related to the number of the first resource and the first event and 2) the determined location where the missing data is identified,
- wherein the first event is activity using the first resource.
