Hit based calculation of profile score

[TimWaijers]

We want to build our audiences based on traits and scoring, is it possible to enrich data by performing calculations on it?

The idea is that at each new hit a specific value is recalculated based on it's previous value and the value that comes with the current hit.

Is it possible to do these calculations within AudienceStream?

Hi @TimWaijers

It is indeed possible to calculate a scoring model in AudienceStream.

If you just wish to have a Visitor/Visit number that is incremented by an event attribute, that is fine.  More complex scoring methods are also possible.

If you wish to give a bit more detail on what your scoring method is, I can guide you further

Hi Mark, thanks for your reply. 

We'd like to use a relatively simple algorithm that calculates the new score based on the current score and some other factors (such as time passed since last calculation).

Something like this: x= (x/2 + y*(z-z*0.5))/4

so the question really is; what mathmatical operators can we use and how can we use them?

Hi @TimWaijers,

That score should be calculable in AudienceStream, although you won't be able to do it in a single "line of code".  You will need to do it step-wise, using intermediate attributes.

The mathematical operators that are available for a Number Attribute at the Visitor or Visit level are;

Increment / decrement by constant or other number
Ratio / Product of two numbers
Difference / Sum of two numbers
Set Number to other number
Calculate Change in other Number

And from Dates at the Visitor or Visit level, you can calculate into a number either the difference in two dates in minutes, hours, days, etc or the change in a single date based on this event in minutes, hours, days etc

The list above is not exhaustive - you can do other things with numbers and other attribute types in AudienceStream.

I can't sum 2 dates or one date + 5 days, what solution would you recommend for this?
