Data Repository

 This page lists all data sets available for various data integration / data wrangling tasks. Some of these data sets have been created by our group. Some have been collected from other websites or research groups. If you use the data in this repository, you can cite using the following bib item: 

           title = {The Magellan Data Repository},
           howpublished = {\url{}},
           author = {Das, Sanjib and Doan, AnHai and G. C., Paul Suganthan and Gokhale, Chaitanya and Konda, Pradap and Govind, Yash and Paulsen, Derek},
           institution = {University of Wisconsin-Madison}}

This will help others to obtain the same data sets and replicate your experiments.

The 784 Data Sets

These 24 data sets were created by students in the CS 784 data science class at UW-Madison, Fall 2015, as a part of their class project. While the data was originally created for entity matching purposes, it can also be used to do experiments on other tasks, such as wrapper construction, data cleaning, visualization, etc. More details
