Themes

The SPARKS team is composed by 3 Themes.

Activities within this research theme address the general problem of reconciling formal semantics of computer science (e.g. logics, ontologies, typing systems, protocols, etc.) on which the Web architecture is built, with soft semantics of people (e.g. posts, tags, status, relationships, etc.) on which the Web content is built. The research works in this theme contribute to the understanding of these graphs by (1) proposing multidisciplinary approaches to analyze and model the many aspects of these intertwined information systems, their communities of users and their interactions, and (2) formalizing and reasoning on these models using graph-based knowledge representation from the semantic Web to propose new analysis tools and indicators, and support new functionalities and better management. The research objectives of this theme can be grouped according to three main topics: (1) supporting HumanComputer Interaction (HCI) and Human Data Interaction (HDI), (2) supporting interaction between users and (3) reasoning and interacting with knowledge graphs. As a corollary, we design user-centered models and methods and we conduct user experimentations and user evaluations of the algorithms and platforms we develop.
