Thanks Davide for your insights.  Will definitely look at the bhave.network.

Hi,

1) Right now I'm using MIT's libraries with Octave for compute different kinds of network's indicators. I'm using Gephi for visualization in parts (days or months) because my network is very huge (218 millions of records). I process data in parts (days or months), and stored through octave matrix .

2) Gephi have some functionality to share your visualization but I have not tried it yet.

3) Right now I'm testing another approach. I'm using MySQL as data store and using the functionality of Gephi to connect the data. It's seem works.

Thanks Liliana

Seems the idea is to do partial construction of the graph/network.

Will give this a thought as well

Thanks Davide. We're looking at adjacency lists or adjacency matrixes to build the graph (but fitting in memory is still a concern). Giraph was a consideration, but we would prefer a non-parallel solution. Cassivary looks promising - thanks for sharing

Dear Chiung Ching Ho,

We've been researching streaming algorithms and visualization methods or tools for online social networks visualization. Feel free to check our research. If you need any help I'll be gald to provide further assistance.

Regards,
