Connected Intelligence

One Year Research Engineer Position – Web Developer – RESTful Web APIs, Semantic Web, Web of Things – (Java, JavaScript)

In the context of a research collaboration with a major French company in the energy domain, ARMINES recruits a research engineer for a one year position in the Connected Intelligence team, Hubert Curien Laboratory, Saint-Étienne, France.

Context

The Internet and the Web nowadays connect not only humans, not only machines, but a variety of communicating things with variable resources and roles. It is a complex task to make systems interoperable on a Web that comprises various protocols (HTTP, CoAP, MQTT), data formats (XML, JSON, CBOR, Protocol Buffer, Turtle), data models (schemas, ontologies), and services (measuring, controlling, forecasting, requesting). As concrete examples, suppose the following things are interconnected on the Web:

In the Connected Intelligence team, we are interested in making these various interconnected things interoperable. More specifically, we are developing solutions that make use of the Web of Data and the Semantic Web standards and formalisms. Originally, these formalisms focus on things (i) with reasonable computational resources, and (ii) connected via HTTP. We hence research how to make the Semantic Web formalisms applicable to things with constrained resources, that use other protocols (CoAP, MQTT), and lighter data formats (CBOR, Protocol Buffers).

  2. Enhance SPARQL-Generate [3], and develop and expose web demonstrators.
  3. Implement SPARQL-Template on top of Jena [4].
  4. Enhance the documentation website of some ontologies developed by the team (for instance, [5]).
