About the research centre or Inria department
The Inria Sophia Antipolis - Méditerranée center counts 34 research teams as
well as 8 support departments. The center's staff (about 500 people including
320 Inria employees) is made up of scientists of different nationalities
(250 foreigners of 50 nationalities), engineers, technicians and
administrative staff. 1/3 of the staff are civil servants, the others are
contractual agents. The majority of the center's research teams are located in
Sophia Antipolis and Nice in the Alpes-Maritimes. Four teams are based in
Montpellier and two teams are hosted in Bologna in Italy and Athens. The
Center is a founding member of Université Côte d'Azur and partner of the
I-site MUSE supported by the University of Montpellier.
In the context of the DeKaloG ANR project (2020-2023) the Wimmics team at
Inria Sophia Antipolis Méditerranée and I3S Université Côte d'Azur offers a
Research Engineer position.
The partners are GDD from university of Nantes and BD from INSA Lyon.
The theme of the DeKaloG project is Decentralized Knowlege Graph in a Linked
Open Data approach. The goal of the project is to design and implement an
architecture that leverages existing Knowledge Graphs and SPARQL endpoints in
such a way as to facilitate KG discovery, federated query writing and
processing, transparency in data and results and efficiency.
In the context of this project, a semantic knowledge graph index must be
designed, implemented and evaluated.
The research topic of the post doc is to design and implement a semantic index
for distributed Knowledge Graphs that 1) facilitates the discovery of
relevant KG for a query, 2) facilitates the writing of the query by proposing
relevant entities, properties and classes, 3) enables users to query and
discover relationships between KG and 4) facilitates efficient federated
query compilation and execution.
The recruited person will be in connection with Wimmics Inria team members and
university of Nantes and INSA Lyon project members.
The person recruited is responsible for realizing, with Wimmics team, the task
assigned to Wimmics in the project and will take relevant initiatives for
carrying out the task.
The person recruited will be in charge of managing master internship in
collaboration with Wimmics team.
The work will start by a literature review to write a state-of-the-art on
Knowledge Graph Index.
Then a graph index ontology will be specified and a graph index architecture
will be designed and implemented. It will be available as an RDF Knowledge
Graph in a SPARQL endpoint. Benchmarks on existing KG such as Wikidata and
DBpedia will be realized.
Scientific publications will be written with the possibility to attend
The candidate will have a leadership role for the Wimmics task and as such
will participate to project meetings in France and will write deliverables of
the project. Visit to partner teams will be realized.
