Using data-integration techniques, we provide a browser extension which augments HTML tables with
additional data from Freebase. Users can choose to display columns which are not present in the
original table, but for which data exists in Freebase, providing direct benefit.
Additionally, users can contribute data contained in the table to Freebase with minimal effort, by selecting from an automatically ranked
list of possible object properties the table column could correspond to.
Report
You can turn the HTML table augmentation on and off by either clicking on the monkey icon in the bottom right corner of the
browser, or by enabling/disabling the script (Tools->Greasemonkey->Manage User Scripts).
Some Disclaimers:
It can be slow on large tables
Our handling of Column Headers identification is not that great,
but this could be easily improved
Contributing:
If you would like to contribute data from HTML tables to Freebase, you will have to edit the script with your Freebase username and password (you must have an account in the Freebase Sandbox):
Tools->Greasemonkey->Mange User Scripts
Highlight "Freebase HTML Tables"
Click on "Edit"
Search for the following lines: USERNAME=""
PASSWORD=""
and enter your Freebase username and password inside the quotation marks.
Note that it's currently configured to only make contributions to the Freebase Sandbox which is wiped every Monday
Example Tables
Following are some tables where it works fairly well:
