Query: Analysis of Link Formation, Persistence and Dissolution in NetSense Data   We study a unique behavioral network data set (based on periodic surveys and
on electronic logs of dyadic contact via smartphones) collected at the
University of Notre Dame.The participants are a sample of members of the
entering class of freshmen in the fall of 2011 whose opinions on a wide variety
of political and social issues and activities on campus were regularly recorded
- at the beginning and end of each semester - for the first three years of
their residence on campus. We create a communication activity network implied
by call and text data, and a friendship network based on surveys. Both networks
are limited to students participating in the NetSense surveys. We aim at
finding student traits and activities on which agreements correlate well with
formation and persistence of links while disagreements are highly correlated
with non-existence or dissolution of links in the two social networks that we
created. Using statistical analysis and machine learning, we observe several
traits and activities displaying such correlations, thus being of potential use
to predict social network evolution.
