how to build recommendation engine to OSM

Hey can any help how to build recommendation engine to OSM
can i use mahout.apache recommendation engine to osm
check this like for code http://mahout.apache.org/

As far as I can see also from http://en.wikipedia.org/wiki/Apache_Mahout there has been no project before about your aim according to include raw OSM data.

So if you want to have a more detailed answer, you should give us examples what Mahout is about, and what is your aim about OSM.

Also try to ask at http://gis.stackexchange.com

From the Mahout website:

Which of the three use cases do you want to implement ? What is your goal ?
" build recommendation engine to OSM " does not mean a lot to me.
