Augmented Social Network

Problem

Online community(aka social networks) tools have been very powerful. But… can we extend more? Extend communication across social

networks? What are the challenges? Communities are becoming walled

castles!

What is ASN?

ASN vision is to build identity and trust

into the architecture of the Internet, in the public interest,

in order to facilitate introductions between people who share affinities or

complementary capabilities across social networks.

ASN: High-level goals

Find others with whom you share affinities

Share relevant information & media with one another

Establish persistent online identity (to establish Internet as a platform for trust)

Self-organize and more easily form alliance with our neighbors

How would ASN enhance online user experience?

Scenario1: Finding others who share affinities

Jim Bob

Solar energy1 Solar energy2

Jim needs some help with his new project on solar energy.

Jim does not contact Bob. (Both Jim and Bob are unaware of that both of them are part of solar energy community)

Solution: Using persistent identity, Jim would be able to discover Bob’s is involved in solar energy2 and make a solicitation.

Scenario2: Links between communities with common interests

Jim solar energy team needs some expert suggestion on solar cells! In Bob’s solar community, an expert has posted solution but specific vocabulary doesn’t match

Solution: design a sophisticated scheme that doesn't depend on the

specific language so that search query returns results(arguable?)

With the system of interoperable communities, automatically send query to Bob’s community and directly seek answer from specific expert

Scenario3: Media forwarded from trusted sources

Jim’s group => journalism, Bob’s group => technical

Jim’s group member conducts interview with important solar engineer and decide to make it available on net.(with current community systems, its unlikely that Bob’s group will be aware of this)

Solution: Automatically forward the interview from Jim to Bob and in turn

to interested members in Bob’s group. Issues - lot of unnecessary forwarding even though it’s trusted?

Spam filtering?

Scenario4: Automated personal Introductions across communities

Bob’s solar group want to test an implementation of solar cells in small south American village.

Solution: with persistent identity, interoperable communities and brokered

relationships, Bob would be able to discover Jim knows Sam and automated system connects Bob with Sam.

The system allows Sam to evaluate Bob’s reputation!

Scenario5: Brokered personal Introductions across communities

Same as scenario 4 but Bob’s approached Sam because of his highly prized relationship with Mayor of village!

Solution: sophisticated brokering mechanisms are required to instill trust Sam could be approached by an trusted brokering service that

endorses the reputation of Bob.

Persistent online identity

In real life, when you go from one virtual milieu to another, your identity will acquire history Why not the same for online identity? Why do we have to restate our interests are, Who

we know?

As of now, sites are using identities are used mostly for commercial interests Amazon’s track record of your financial transactions

Identity should not be recited to what our purchase interest are (we can not be reduced to what we buy!)

Persistent online identity

Propose a new civil society digital profile Should be multifarious and ambiguous expresses your affinities and capabilities gives people high control over identity

Some Industry initiatives: Liberty Alliance Project, Microsoft Passport

Issues: How about managing digital profile?? Securing digital profile is going to be prime

concern

Why would communication across groups create added value?

Combined Value of N, M member nets

N + M N2 + M2 + 2NM 2N x 2M

Networks that support construction of groups can create value that scales exponential with network size

But as the network size grows larger, identifying affinities gets difficult.

ASN community functionality

Requires writing and adoption of interoperable protocols to enable communication between different communities

Reputation is also important! No universal reputation rather community specific

Matching Framework

Allows for matching even when exact language does not correspond

Two ways: Creation of knowledge maps

Focused efforts to ensure ontologies and taxonomies follow XML/RDF format etc.

Tacit knowledge Automatically inferring from your past history

(user’s online behavior) Amazon’s recommender system

Brokering Services

Act as trusted third parties to enable communication between two people

Introduction protocols form the key

Plain vanilla Introduction protocol A is looking for some information that B has Automatic agent detects this using ontological

framework Automatic agent informs B about this. B could then

take action accordingly.

Customized brokering protocols

In summary…

The ASN would create strategically placed "doors" between online community infrastructures, which today act like "walled castles."

Key takeaways

Concept of Persistent identity Building trust into the Internet can have

significant advantages Maintaining such a digital profile would a big a

challenge though?

One could exploit sharing across social networks for better benefits

Brokering services could be useful for communications across social networks Introduction protocols play a vital role
