Experimental features

As Gephi Lite is built with modern web technologies, it makes it quite easy to draft and develop new features. This is a good opportunity for the Gephi team to try new features in Gephi Lite, that might end up as plugins or core features in Gephi later. Two such experimental features have been implemented already.

Connected-closeness​

Layout quality evaluation in Gephi Lite

At Gephi Week 2024, the team decided to try to implement a way to visualize Mathieu Jacomy's connected-closeness in Gephi Lite. This metric aims at evaluating how successfully a layout does bring together in the plan connected pairs of nodes, while keeping disconnected pairs distant.

The way it's implemented in Gephi Lite is that users can toggle connected-closeness from the Layout > Layout Quality menu. Then, a grid of size Δmax will constantly be displayed, and the caption will show how to read it.

Louvain edges ambiguity​

Louvain edges ambiguity in Gephi Lite

At Gephi Week 2022 this time, some people started to work on a way to evaluate how ambiguous community detection algorithms can be. This led to a dedicated workshop in december 2024, where a team gathered to keep digging.

This ended up in a way to evaluate how consistently the Louvain method for community detection does put extremities of each edge in the same community or not. And various other metrics are derived from this, to map where does the ambiguity lies in the graph.

Stay tuned, hopefully more documentation might come later about this!
