abstract = "This paper presents a genetic programming-based
symbolic regression approach to the construction of
relational features in link analysis applications.
Specifically, we consider the problems of predicting,
classifying and annotating friends relations in friends
networks, based upon features constructed from network
structure and user profile data. We first document a
data model for the blog service LiveJournal, and define
a set of machine learning problems such as predicting
existing links and estimating inter-pair distance.
Next, we explain how the problem of classifying a user
pair in a social network, as directly connected or not,
poses the problem of selecting and constructing
relevant features. We use genetic programming to
construct features, represented by multiple symbol
trees with base features as their leaves. In this
manner, the genetic program selects and constructs
features that may not have been originally considered,
but possess better predictive properties than the base
features. Finally, we present classification results
and compare these results with those of the control and
similar approaches.",
