Query: Trust-based dynamic linear threshold models for non-competitive and
  competitive influence propagation   What are the key-features that enable an information diffusion model to
explain the inherent dynamic, and often competitive, nature of real-world
propagation phenomena? In this paper we aim to answer this question by
proposing a novel class of diffusion models, inspired by the classic Linear
Threshold model, and built around the following aspects: trust/distrust in the
user relationships, which is leveraged to model different effects of social
influence on the decisions taken by an individual; changes in adopting one or
alternative information items; hesitation towards adopting an information item
over time; latency in the propagation; time horizon for the unfolding of the
diffusion process; and multiple cascades of information that might occur
competitively. To the best of our knowledge, the above aspects have never been
unified into the same LT-based diffusion model. We also define different
strategies for the selection of the initial influencers to simulate
non-competitive and competitive diffusion scenarios, particularly related to
the problem of limitation of misinformation spread. Results on publicly
available networks have shown the meaningfulness and uniqueness of our models.
