Just a note to say that there are a few techniques set up to study 
some phenomena on an observational/encoding basis, chiefly ethology, 
which has had many applications in the study of primates and other 
group interactions.
I don't know the computer programming involved, but Franz de Waal 
describes an elaborate code that allows his researchers to transcribe 
the actions of all subjects in a group, which are then entered into a 
computer.  Then programs are run that will reveal patterns of 
interaction or other metapatterns.
It is through the technique of ethology that de Waal revealed the 
varied power structures among primate species.  In _Peacemaking Among 
Primates_, he describes how his researchers gradually uncovered a murder 
plot among a group of chimpanzees that resulted in their leader being 
assassinated one night.
