A tool facilitating matching for any dataset discovery method. Also, an extensible experiment suite for state-of-the-art schema marching methods.

Schema matcher tests based on Valentine

For my master's thesis on schema integration, I did some tests on schema matching algorithms. These are based on Valentine (https://github.com/delftdata/valentine).

Three subfolders with data needed:

• data: https://archive.org/details/data.7z_202303 (data hand-labelled by me)
• Valentine-datasets (datasets used in Valentine evaluation, documented here: https://delftdata.github.io/valentine/ (Zenodo link for data))
• Valentine-output (output from Valentine evaluation, documented here: https://github.com/delftdata/valentine-paper-results (subfolder outputs for data)) Download data, extract it, and place it in subfolders.

Valentine was extended with JaccardLevenshtein matcher based on column names only (https://github.com/Anphisa/valentine/tree/master/valentine/algorithms/jaccard_levenshtein_colnames_only).
