Aggregating similarity metrics

Abstract:

A method, computer system, and a computer program product for determining a composite similarity metric for data of a first data type is provided. The present invention may include providing a plurality of similarity metrics for the first data type. The present invention may also include providing a metric quantifying correlation of entities belonging to the first data type and entities belonging to a second data type. The present invention may then include developing a first regression model to predict values of the provided metric quantifying correlation of entities belonging to the first data type and entities belonging to the second data type using the provided plurality of similarity metrics. The present invention may further include calculating the composite similarity metric from a plurality of first regression coefficients in the developed first regression model.
