 I am a CNRS research engineer involved in the integration of heterogeneous data and their publication and sharing as Knowledge Graphs on the Web, using knowledge engineering, the Semantic Web and Linked Open Data technologies.

I am a member of I3S laboratory's SPARKS group, and a member of Inria's Wimmics team.

Knowledge Graphs, Integration of Heterogeneous Data

I am involved in research activities meant to enable the integration of heterogeneous data based on a knowledge engineering approach, as well as the sharing and reuse of these data. My work addresses several research questions:

  1. How to build FAIR Knowledge Graphs complying with the Linked Data 4-star principles?
  2. How to overcome data structural and semantic heterogeneity in order to reconcile and make sense of large data sets distributed at Web-scale?
  3. How to foster data reuse by publishing them in machine-processable formats? This work is concerned with leveraging the Linked Data principles to integrate heterogeneous legacy data sources and make them available in the Web of Data. This was the main topic of my Ph.D that I defended in 2017, with a specific focus on the translation of data from NoSQL databases into RDF.
  4. How to enable the Web-scale discovery and consumption of data? This work is concerned with methods to make data and query services discoverable, and the types of interfaces that are suitable to consume Linked Data.

I hold several collaborations with researchers in the biodiversity domain. To understand the effects of climate change on biodiversity, researchers have a pressing need to make sense of myriad data produced all over the world by biodiversity-related projects. In this context, I work with the French National Museum of Natural History towards the publication of their data as Linked Open Data. More generally, together with communities like, we strive to enable Web-scale integration of biodiversity.

AIs, and LLMs in particular, are not conscious. They are reactive systems, they respond to an input by producing an output. By contrast, consciousness can be defined as the ability to form thoughts for oneself, without the need for external stimulus.

What if we fine-tuned several LLMs to collaborate together, following the model of human psyche.

  • The “conscious” model would be fine-tuned to remain in the realm of values, morality, norms, and logical thinking. This is the one that would interact with the “outside” world and provide material to the “unconscious” model.
  • The “unconscious” model (or “subconscious” depending on the definitions) would be fine-tuned to phrase drive, desires, regardless of any norms nor value system.
  • The “preconscious” model would be fine-tuned to filter/rewrite outputs of the “unconscious” to let only acceptable outputs make their way to the “conscious”, while also providing it with material in a feed-back loop.

This way, we could imagine being able to design some sort of a conscious AI system. But this raises multiple questions: How would it be bootstrapped? Individually, each of the 3 LLMs remains a question-answering system, it does not take the initiative of producing an output. So how to start this, and once this starts, how to control the flow? If we skip the conscious model (to try and simulate sleep) and leave the unconscious model talk with itself, could it come up with dreams?

Multiple tools of the daily life consume energy and/or resource even though that's not the intend of the user. These tools must be redesigned with a specific bias towards frugality.

This can be implemented as a default behavior, as a nudge etc. Examples:

  • Mixer tap delivers heated water by default: In the middle position, most mixer taps mix half ambient temperature water and half heated water. Although users may not need heated water. These should be redesigned with a middle position that only delivers ambient temperature water, so that getting heated water will require a deliberate action from the user.
  • Public space fountain water delivers cooled by default: Fountains in public spaces usually deliver cooled water by default although users may not want that. These should be redesigned with a default ambient temperature water, so that getting cooled water will require a deliberate action from the user.
