SYSTEMS AND METHODS FOR SELECTING DATASETS

摘要

A method of determining a further dataset to be joined with a source dataset having a plurality of data entries each identified by a respective key. An identifier of the source dataset is received, and an intersection weight between the source dataset and each of a plurality of possible further datasets is determined based on the number of common keys between the source dataset and each respective possible further dataset. An output is then generated based on the intersection weights for use in selecting one of the plurality of possible further datasets to be joined with the source dataset.
