I've started learning and playing around with RapidMiner. I have a data source with textual IDs, and I would like to map those IDs to standard 2-letter tags (they're country names) after I load the data into RapidMiner, so that I can easily join data from different sources. I came up with a solution using a huge long chain of AddNominalValue's and then another chain of AttributeValueMapper's. The problem is that I need one of each for each country name, so it's rather unwieldy and it dominates the file with bookkeeping operators. Is there another, easier way to do this, preferably with a single operator? Thanks.

Hello,

which version of RM do you use? Some time ago, we made the AttributeValueMapper capable of handling multiple mappings. Maybe you are working with an old version? Otherwise please post a snippet of your mapping process part. Maybe we can compress it a little .. Wink
