Bipolar in Temporal Argumentation Framework
  A Timed Argumentation Framework (TAF) is a formalism where arguments are only
valid for consideration in a given period of time, called availability
intervals, which are defined for every individual argument. The original
proposal is based on a single, abstract notion of attack between arguments that
remains static and permanent in time. Thus, in general, when identifying the
set of acceptable arguments, the outcome associated with a TAF will vary over
time. In this work we introduce an extension of TAF adding the capability of
modeling a support relation between arguments. In this sense, the resulting
framework provides a suitable model for different time-dependent issues. Thus,
the main contribution here is to provide an enhanced framework for modeling a
positive (support) and negative (attack) interaction varying over time, which
are relevant in many real-world situations. This leads to a Timed Bipolar
Argumentation Framework (T-BAF), where classical argument extensions can be
defined. The proposal aims at advancing in the integration of temporal
argumentation in different application domain.
