Method for determining data quality in a knowledge management system

摘要

A method for calculating a confidence score for a data element that includes substantive technical data in a computer interpretable form and is adapted to be utilized by a knowledge management system. The method includes the steps of encoding substantive technical data in the data element, tracking a plurality of component factors for the data element, calculating a plurality of component scores for the data element wherein each individual component score corresponds to an individual component factor, and calculating the confidence score for the data element based at least in part on the plurality of component scores.

1. A computer implemented method, comprising:
storing, at a knowledge management system server, a data element that codifies the know-how of an expert into a computer interpretable form, the data element having an identifier that allows the data element to be identified and technical information, wherein the technical information includes at least one of a rule that correlates one or more input values to one or more output values, a parametric relationship, a conditional relationship between, values and a mathematic expression, and the technical information of the data element is usable by a user workstation to perform at least one automated function; receiving, at the knowledge management server from the user workstation via a communications network that facilitates data transmission between computers, requests for the data element, wherein the requests include the identifier; transmitting, to the user workstation via the communications network, the data element in response to the requests; receiving, at the knowledge management system server from the user workstation via the communications network, information indicating whether utilization of the technical information of the data element produced a valid result or an invalid result tracking, at the knowledge management system server, usage data for the data element that includes a number of times that the data element has been used; tracking, at the knowledge management system server, conformance data for the data element that includes a number of times that the data element has produced invalid results; tracking, at the knowledge management system server, status data for the data element that corresponds to one of a plurality of pre-defined status values; tracking, at the knowledge management system server, age data for the data element that includes at least one of time elapsed since creation of the data element, time elapsed since modification of the data element, or time elapsed since review of the data element; calculating, at the knowledge management system server, a score representing the accuracy of the technical information in the data element, wherein the score is based in part on the usage data for the data element and the score increases as the number of times that the data element has been used increases, the score is based in part on the conformance data for the data element and the score decreases as the number of times that the data element has produced invalid results increases, the score is based in part on the status data for the data element, and the score is based in part on the age data for the data element and the score decreases as at least one of time elapsed since creation of the data element, time elapsed since modification of the data element, or time elapsed since review of the data element increases; and transmitting, from the knowledge management system server to the user workstation via the communications network, the score.
