Moleskine’s philosophy is culture, travel, memory, imagination and personal identity.

For example, we will look at how people connect in Twitter and create a weighted graph using both following numbers and @mentions. We will look at all platforms and cluster groups of posts by trending topics using LDA. This can be applied to all sources of media. We will then try to identify if trending topics and influencers are common across social platforms.
