Longitudinal Citation Prediction using Temporal Graph Neural Networks
Citation count prediction is the task of predicting the number of citations a
paper has gained after a period of time. Prior work viewed this as a static
prediction task. As papers and their citations evolve over time, considering
the dynamics of the number of citations a paper will receive would seem
logical. Here, we introduce the task of sequence citation prediction, where the
goal is to accurately predict the trajectory of the number of citations a
scholarly work receives over time. We propose to view papers as a structured
network of citations, allowing us to use topological information as a learning
signal. Additionally, we learn how this dynamic citation network changes over
time and the impact of paper meta-data such as authors, venues and abstracts.
To approach the introduced task, we derive a dynamic citation network from
Semantic Scholar which spans over 42 years. We present a model which exploits
topological and temporal information using graph convolution networks paired
with sequence prediction, and compare it against multiple baselines, testing
the importance of topological and temporal information and analyzing model
performance. Our experiments show that leveraging both the temporal and
topological information greatly increases the performance of predicting
citation counts over time
Transforming knowledge systems for life on Earth : Visions of future systems and how to get there
Formalised knowledge systems, including universities and research institutes, are important for contemporary societies. They are, however, also arguably failing humanity when their impact is measured against the level of progress being made in stimulating the societal changes needed to address challenges like climate change. In this research we used a novel futures-oriented and participatory approach that asked what future envisioned knowledge systems might need to look like and how we might get there. Findings suggest that envisioned future systems will need to be much more collaborative, open, diverse, egalitarian, and able to work with values and systemic issues. They will also need to go beyond producing knowledge about our world to generating wisdom about how to act within it. To get to envisioned systems we will need to rapidly scale methodological innovations, connect innovators, and creatively accelerate learning about working with intractable challenges. We will also need to create new funding schemes, a global knowledge commons, and challenge deeply held assumptions. To genuinely be a creative force in supporting longevity of human and non-human life on our planet, the shift in knowledge systems will probably need to be at the scale of the enlightenment and speed of the scientific and technological revolution accompanying the second World War. This will require bold and strategic action from governments, scientists, civic society and sustained transformational intent.Peer reviewe
