SYSTEM AND METHOD FOR ESTABLISHING RELATIONSHIPS BETWEEN DATA ELEMENTS
A computer implemented system and method to determine relationships between data elements using a knowledge graph are described. The method comprises establishing a knowledge graph having graph elements, associating weights with data elements and determining at least some of these weights to be modifiable weights. Training data is used to determine the relationships between data elements in the knowledge graph by calculating the strength of the relationship. The calculated relationship strength values are compared to previously established relationship strength values, and one or more modifiable weights are modified to reduce the error between the calculated and established relationship strength values. These steps are repeated until a matching criterion is reached.
