Supporting Libraries and "PyG Ecosystem"

[maddataanalyst]

Hello PyG Team,

I'm a researcher at Wrocław University of Economics specializing in graph neural networks for quantitative management applications. PyG has been instrumental in my work on organizational analysis and financial transaction networks—thank you for maintaining such an excellent library.

I'd like to inquire about PyG's approach to ecosystem libraries and community tools (I don't mean contributing to the PyG package directly as it is not always in its direct scope). Many major frameworks maintain ecosystem pages or partner library listings, and I'm curious if PyG has considered something similar.

My colleague @mmalczewski and I recently published HeXtractor, a tool for transforming tabular and text data into PyG HeteroData objects. It's been peer-reviewed and published in the Journal of Open Source Software (documentation). The library provides a configuration-driven approach to graph construction from heterogeneous data sources.

We're also preparing to develop a bridge between Surprise and PyG to leverage Surprise's recommendation system capabilities with PyG's graph structures.

I know at least a couple of other research groups building specialized tools on top of PyG (including applications in fraud detection and money laundering analysis).

An ecosystem page could help users discover complementary tools, reduce duplicate effort in the community, showcase PyG's versatility across domains and create the PyG ecosystem similar to PyTorch's approach (torchmetrics, torchrl, sktorch, etc.).

Have you considered, or already have such a hub for related projects/ecosystem?

All the best wishes, and 1000 kudos for you all :)

Hi @maddataanalyst, thank you for opening this thread. We list a few projects at https://pyg.org/ecosystem, but is the page something you're referring to?

Hello! Oh my it's on a plain sight!... My bad indeed, sorry. I was searching mostly on the docs page, must have overlooked it.

Do you have any contribution rules or requirements to join this list or is it based on the PyG Team's judgement and decision?
