The statistical AI algorithm to analyze communication networks

Try Linkage

Why Linkage ?

Understand your communication networks with the help of AI

Why Linkage Picture

Linkage allows you to cluster the nodes of networks with textual edges while identifying the topics used in communications. You can analyze networks such as email networks or co-authorship networks. Linkage allows you to upload your own network data or can help you build data to be analyzed.

What we do

What does make Linkage so unique ?

How does Linkage Work ?

Linkage is built upon a sound statistical AI model for networks with textual edges and implement an innovative and efficient AI algorithm to uncover patterns in your data. A model selection criteria allows to find in a fully automatic way the best model for your data.

Upload and manage your data securely

Upload all or part of your data on the platform to analyze them with Linkage. You will keep full control on the data you upload and only you will be able to access them.

Focus on data and interpretation

Minimum configuration is required to use Linkage since it selects the most sensible parameters for the data you provide. No scientific background is required to start working and get results. Advanced configuration options are also available if you need specific setups.

Visualize and export the results

Linkage also provides advanced visualization tools to present the uncovered results. It also allows you to export as CSV files the clustering results obtained on your data for further processing.

Linkage Technology

How does Linkage work ?

The statistical AI method behind the platform

The methodology implemented is partly related to an article published in the journal « Statistics and Computing ». The reference to cite in case of academic use of the platform is :

Bouveyron, C., Latouche, P., & Zreik, R. (2018). The stochastic topic block model for the clustering of vertices in networks with textual edges. Statistics and Computing, 28(1), 11-31.


Linkage technology has been patented in 2020 and is now protected in the US. You can access the official document here :

Method for clustering nodes of a textual network taking into account textual content, computer-readable storage device and system implementing said method. US Patent n°10671936 B2
