hello community!

we are facing this challenging issue. We need to complete for a vast amount
of records, the dewey, UDC info, has anyone had any experience with this?
We need some way (via modeling? mahout?) to try and discover these values,
based on some text, found in the records' metadata, and then auto complete
these values.

I would appreciate any feedback, if there is any opensource tool you have
used for this purpose, or if you are aware of any best practice for doing
this task.

Best
