Mass taxonomy attribution (module) ?

Hi there,

I'm migrating my self developed website to Drupal 6.
I've imported 400 articles and it works fine BUT I now have to add a taxonomy to each of these articles...
Is there an administration panel / module that allows to do that quickly ?
I'm thinking to something that displays 10 lines in a single page, each line beeing composed by the title of the node and the taxonomy box.

Any idea of where i can find this jewel ?

Many thanks
