Structural Invariants in Individuals Language Use: The "Ego Network" of Words

The cognitive constraints that humans exhibit in their socialinteractions have been extensively studied by anthropologists, who havehighlighted their regularities across different types of social networks.We postulate that similar regularities can be found in other cognitiveprocesses, such as those involving language production. In order to providepreliminary evidence for this claim, we analyse a dataset containingtweets of a heterogeneous group of Twitter users (regular users and professionalwriters). Leveraging a methodology similar to the one used touncover the well-established social cognitive constraints, we find that aconcentric layered structure (which we call ego network of words, in analogyto the ego network of social relationships) very well captures howindividuals organise the words they use. The size of the layers in thisstructure regularly grows (approximately 2–3 times with respect to theprevious one) when moving outwards, and the two penultimate externallayers consistently account for approximately 60% and 30% of the usedwords (the outermost layer contains 100% of the words), irrespective ofthe number of the total number of layers of the user.
