social networking analysis

hi all
I spoke at drupal camp india on building social networking sites with and around drupal. Basically I wanted to share my experiences good/painful with social networking sites with drupal as platform. Below is the link to presentation I gave, As mentioned this was more experience sharing than "Teaching" where I majorly discussed existing module stack available and issues with them (as SNS enablers) and where did I hit the wall and how did I resolve it.

I plan to modify to module according to Drupal 5 requirements. It can be expected in December month. I assume that there are not so things to rewrite, because the biggest part of the module is Drupal-independent code.
Watch the project website to track the upgrade.

Finding out, how data is related to another one is easy to be represented as a "Model View Controller".

As an example: If relations between users are build through the buddy.module we know the direct relation between 2 users. What we want to figure out is the "shortest path" between 2 users, who are not buddied.

M: Array of known relations (optionally with weight)
V: Visualisation of the path like shown at http://sna.drupaler.net/?q=de/node/13
C: Dijkstra's algorithm for "Shortest Path"; http://sna.drupaler.net/?q=de/node/10 ; sna.module

If following relations-Model (with weights) exists:

For some marketing and SoC reasons, I have set up the http://drupaler.net/
I would be glad if PR-related information would be posted here, too.

As allready published at http://drupal.org/node/65828 :

At http://drupaler.net/ we are happy to announce the "Who is who?" drupaler site.

We are trying to collect:
- User profiles: http://drupaler.net/user/1
- User locations: http://drupaler.net/map/users
- Working groups: http://drupaler.net/og

for public access and these for registered:
- Chatbox: http://drupaler.net/chatbox
- Buddylist: http://drupaler.net/buddylist
- Several content types: http://drupaler.net/node/add

It's exciting to read about the Social Networking Analysis (SNA) Tool that is 1 of 14 2006 Summer of Code projects selected to write Drupal code with the financial support of Google.

Kudos to Robert Douglass and Angela Byron for all their excellent work in helping put together the 2006 SOC!

The basic SNA module is an analysis tool that will map and analyze how nodes and users are interlinked. It is useful for knowledge management in organizations because it provides an insight on what nodes have greatest value and which users are frequently tapped by other users for knowledge. Since node analysis (eg most popular nodes) is already existent in other modules, we will focus here on an analysis of user networks.
