- Reputation systems: a possible path for investigation
*J C Lawrence*Reputation systems are usually thought of as interesting ways for the

game system to define and provide predetermined and service-qualified

hinting and decision making keys to players about other players (PK,

trade, trust etc). To date this has been an uncomfortable and halting

process which is behind the needs curve and chasing the definition of

both the actual requirements and possible implementation models which

don't carry excessive collateral costs. Additionally, little has been

done to extend these player-derived reputation systems to represent

player views of in-game artifacts and systems.

Part of the problem is that the hinting data requested is contextual and

subjective, both at the time of the sequence points that form reputation

atoms and at the time the reputation is reported and interpreted by a

particular player at a particular place and time for a particular

purpose. More explicitly the needs definition at both ends is not

uniform across an entire game or for all players of that game.

Sometimes the problem for a reputation system is as trivial as, "Who

is online right now that I'd like to play with?" Other times its as

subtle as, "Can I trust him to proxy my in-game interests when I'm not

here?" say for minding a co-owned store, a merchant cooperation, money

trading, or even simple employee/employer or client/patron

arrangements. Then there are the simple questions like, "Is this

rotting rope bridge safe to cross?"

Arbitrary graining and subjective contextual per-player interpretation

seem to be called for, but are not an attractive implementation or

management prospect, especially for a casual gamer audience, and more

especially for a centrally defined, managed, and reviewed set of

metrics. A possible approach instead is to treat the players as a

homogeneous mesh and allow them to define the nouns and verbs in the

reputation system, and possibly some of the high level grammars.

Guilds and other player group formations have partially coopted this

reputation space, using membership and internal group management as a

way of establishing and maintaining reputation at a group level ("He's a

member of guild XXX. They're all PKers!"). Problems of this approach

are a lack of transparency and high barriers to entry both in social

networking and learning curve before that reputation data can be

effectively used. Additionally such group-derived structures select

against casual gamers who don't invest the time or effort required to

breach those entry barriers and yet need and want an effective

reputation system for themselves as represented to others, and for

others as represented to them.

Of course if these needs and wants were fully satisfied by the base

system it would remove one of the significant functions which drive

group formation and interaction on our services. Depending on the

exact definition of your service and audience this could be a problem.

In the general case however I expect that the other forces which drive

group formations like guilds would still dominate. However it would

change some of the basic definition and functions of guilds with

games.

Content creation costs are a significant expense, making community

authored content attractive -- if only the risks of "bad content" could

be managed (where bad can refer to legal branding, service, product

definition or other implications). Reputation systems are a possible

approach to helping to automate the detection and handling of bad

content so that human supervision and vetting costs for instantiating

and official sanctification of community derived "good content" (if your

model calls for that) can be constrained.

First Monday (http://www.firstmonday.org/) has several papers which

intersect these areas. In particular:

Open content and value creation by Magnus Cedergren

http://www.firstmonday.org/issues/current_issue/cedergren/index.html

The Augmented Social Network: Building identity and trust into the

next-generation Internet by Ken Jordan, Jan Hauser, and Steven Foster

Cat Okita presented a paper on a peer-to-peer authentication system at

DefCon called "Aura" which also looks interesting (he promises sample

source RSN):

These aren't a compleat set; just bits I've been reading and musing on.
