In brief,
From numbers to texts, I obtained a master's degree in data science and have been playing with language since 2016. I spent three years with DataObserver, developing information monitoring solutions integrating NLP, dataviz, and graph mining. Interested in social and humanist questions, I completed a Digital Humanities master's in 2018 at the University Lyon II. I started to work on semantic web questions at Ottawa DH Lab. Finally, I became a research engineer in the Wimmics team of Inria Sophia-Antipolis. I had the opportunity to update and extend the French chapter of DBpedia for a year, which I am still maintaining. I am today PhD student thanks to the 3IA convention

ISSA Hackaton
With Benjamin Molinet we participate in the ISSA Hackathon for two days from the 28th to the 29th of October. The ISSA project is a scientific open data hub focused on biological and agriculture research. During this two days coding marathon, we developed a framework for publication analysis based SPARQL query specificity index computation, and language model-based keywords retrieval.
GSOC project - DBpedia Abstract
From June to September 2022 I participate to the Goggle Summer Of Code. This event allow development of open source projects via a monitored project that each project team submitted.
DBpedia was one of the association that monitored projects : DBpedia provides monthly releases produced by the DBpedia Extraction Framework. They are composed of various data artifacts that mainly stem from the wiki dumps.
However, some of them also rely on API calls for rendering dynamic contents, which is the case of the DBpedia abstracts. The large amount of data requested from APIs couldn't be extracted entirely within a month today.
For solving it i tried severals stragtegies : a wikimedia docker clone, I also corrected current API usage and extended the DBpedia code source for being able to call an alternative API, that could be use for getting the entire text of a wikipedia page.
The french DBpedia chapter
From Nov. 2021 to December 2022, I updated and extended the French DBpedia. DBpedia FR is now investing the databus for updating the endpoint.
The Knowledge base is now structured into structurated into named graphs, allowing a fine source evaluation Every Dbpedia article related to Wikidata is now enriched by the enriched by the Wikidata information available. I also update new infoboxes where updated on mapping fr wiki for still being able to follow the related articles. I also had the opportunity to contribute DBpedia DIEF source code by working on the DBpedia abstract, DBpedia History, and the integration of the Sister projects links.
Programming Historian
The Programming Historian is a open-source and open-reviewed online journal, which publish tutorials for historians and more broadly digital humanits. The journal is available in four languages (english, portuguese, spanish and french). From OCR step, to the analysis of textual corpora, PH tutorials are given methodological keys into pratical use cases.
In 2021, i joined the team of the french chapter of Programming Historian as editor. Where I was implied into the reviews of translations, original lessons, but also as translator on some of these.
Harry Potter Mining
In 2021, I tried to obtain a CAPES NSI, a new french diploma for teaching algorithm, and IT basics in high schools. Of 1000 candidates only 100 places were given. Without enough preparation, I didn't get it.
I choose to introduce data mining technics, based on the Harry Potter books analysis. From the extraction of the chapter, the main characters, and the emotions, we can explore the evolution of the social network of Hogwarts. We also introduce classification algorithms on which the Sorting Hat evaluates if a new scholar must the Slytherins.
