Data lakes are massive repositories of raw and heterogeneous data, designed to meet the requirements of modern data storage. Nonetheless, this same philosophy increases the complex…
Measuring and Predicting the Quality of a Join for Data Discovery
Sergi Nadal, Raquel Panadero, Javier Flores +1
We study the problem of discovering joinable datasets at scale. We approach the problem from a learning perspective relying on profiles. These are succinct representations that cap…
Scalable Data Discovery Using Profiles
Javier Flores, Sergi Nadal, Oscar Romero
We study the problem of discovering joinable datasets at scale. This is, how to automatically discover pairs of attributes in a massive collection of independent, heterogeneous dat…
