Since 2014, the tree cloud construction module handles Unicode characters and includes several linguistic preprocessing operations (stopword deletion, detection of multi-word expressions) performed by Unitex, added by Claude Martineau.

The integration of Unitex into TreeCloud was continued by Claude Martineau in 2017, on the occasion of the ECLAVIT research project (see poster in french, in english).

During June 2014 to July 2014, S Deepak Srinivas implemented the algorithm proposed by Barthelemy and Luong (1987) in their paper in C. And the visualization of the tree has been done in JavaScript (using the d3.js library).

Many advises and examples were useful in the design and use of tree clouds. More details about those are given in the Acknowledgement section of these two articles, and in the version history of TreeCloud.
