If you add sufficient intellectual property from your own efforts to something that was originally produced by someone else, and you don’t show anything extraneous from the original, then you don’t need the originator’s permission to publish what has become, on balance, your intellectual property but you should acknowledge their original contribution. Of course, if the original originator is still contactable, it is always a good idea to communicate with them before publishing your own work, they may after all have discovered something else new in the meantime, but there is no obligation too.
Note that basic lists can never be considered as intellectual property.
