Do you know an item is in NY? or are you trying to find what is =
preferred by New Yorkers?

If the latter send events (user-id, location-preference, location-id) as =
secondary events. The location-id should be chosen to include some =
people but not too many so there is variation in what New Yorkers prefer =
vs Las Vegas denizens. I=E2=80=99d use postal codes (zip codes) or phone =
area codes for coarser granularity. The benefit of using these =
code-systems is that they are never dups like 2 cities with the same =
name. Also lat-lon doesn=E2=80=99t work since not 2 people can existing =
in such a fine grained location. =20

Once you determine the location encoding scheme you=E2=80=99ll use, =
determine how many possible location-ids you=E2=80=99ll have. This =
should affect the param maxCorrelatorsPerItem described here: =
http://actionml.com/docs/ur_config <http://actionml.com/docs/ur_config> =
Set it to a number much smaller than the total number of location-ids =
you have. For instance if you were using user gender you'd set this to 1 =
(actually this is an extreme and would use another method but serves to =
illustrate)

I need to store event data based on user location like user =3D 1 coming =
from New York viewed an item, then user =3D 1 coming from New York =
bought item. I want to recommend items to other users are viewing in New =
York itself.

So please help me out with indicator params in engine.json and how to =
efficiently set event,user and item data.

Thanks
Gaurav


So how shall i proceed with set event or i need to put every item =
against every location and=20
