# The Peer archetype

### Initial Parameters for $$\upsilon$$

Initially, we will be using three (3) main parameters for evaluating an individual’s Peer Value (Global Reputation):

* The *Centrality* ( $$\alpha$$ ) of the contribution of a Participant across their Hubs.
* The *Betweenness* (Interconnection) ( $$\beta$$ ) of a Participant respect to their peers.
* The *Variety* ( $$\gamma$$ ) in the Contributions delivered by a Participant across all their Hubs.

On a concrete level, they also identify the main "archetypes" of a value-contributor:

* The *Pillar* ( $$\alpha$$ ) 
* The *Socialite* ( $$\beta$$ ) 
* The *Polymath* ( $$\gamma$$ )

From these archetype we can extract a compound parameter, called *Peer archetype (* $$\mathring{a}$$ ):

$$
\displaystyle \mathring{a}*{\tiny (j, \tt H \cdot)} = \frac {(w*{\tiny \alpha} \times \alpha) + (w\_{\tiny \beta} \times β\_{\tiny j}) + (w\_{\gamma} \times \gamma)} {3}
$$

where:

* $$\mathring{a}\_{j, \tt N \cdot}$$ is the *Peer archetype* of Participant j across all their Hubs $$\[\tt h \cdot]$$ in the set $$\[\tt H \cdot]$$.
* $$\alpha$$ is the Centrality of *j's* **Participation Score (PS)** in all their Hubs.
* $$\beta$$ is the Interconnection (Betweenness) of *j* with their peers.
* $$\gamma$$ is the variety of *j*’s contributions across their Hubs

The dominant parameter will determine the *Archetype* of the Contributor *j*.
