Hi Sun,
Does Koha have a bulk authority import tool like Koha's bulkmarcimport.pl script? I have a set of authority records exported from Horizon? In the misc/ dir you'll find a tool called 'bulkauthimport.pl' which will give you some ideas for how to build such a import tool for your library. Koha does not currently include a fully complete tool, as easy to use as bulkmarcimport.pl, though I'm sure a future version will include one.
If you find the process of importing your authorities a bit daunting, feel free to post to the devel list or consider one of the support options available: http://koha.org/support/pay.html Hope that helps.
