Hello!
I wish to contribute to Xwiki as part of GSoC program this year!
Here is a draft of my proposal for Content-based Tag suggestion
Still analysing and exploring some of the parts of problem statement, but I would love to get feedback on the proposal and improve upon it
Tagging mentor for the project @MichaelHamann 
I wish you a great weekend and I patiently await for your feedback!
Best!
