Question Regarding preference values

Hi,

I am having a huge data set which do not have the preference value related
to it.
Now we have decided that we will be calculating / adding preference values
to the newly added items.

In this case how we can get started using the whole data set i.e the old
dataset(with no preference values) & the new dataset (with preference
values)

How do we use the old dataset?

Thanks,

*Komal Goyal*

I would simply assign some neutral value to all of the old values.
Perhaps you would assign a 3.0, if on a scale of 1 to 5? The most
sensible value depends on your input though.
