Various techniques are described, including evaluating ingested data including a dataset to identify one or more links to other datasets stored in a graph, using a similarity determination algorithm to identify a degree of similarity between datasets to determine joinability of ingested datasets with graph-stored datasets, determining a ratio to determine whether to perform an overlap or coverage function, associating a subset of similarity matrices with a subset of graph data joined to the ingested dataset, and forming links in a column of data between the dataset and the another dataset of the ingested data based on the degree of similarity.
