Recent Projects

PRISSMA Context-Aware Presentation Layer for Linked Data

PRISSMA is a Linked Data rendering engine that selects the most appropriate RDF presentation according to mobile context, using graph edit distance to compute error-tolerant subgraph isomorphisms between context graphs.

Shi3ld Context-Aware Authorization for Graph Stores

Shi3ld is an access control (authorization) module for triple stores. Shi3ld protects SPARQL queries and HTTP operations on Linked Data.

An annotated RDF dataset polluted by syntethic malicious triples. Useful to train and test Linked Data spam filters.


PhD Dissertation

My thesis discusses the influence of Context Awareness on Web of Data access.

The work dissects this issue into three research questions:

The thesis contributions include a lightweight vocabulary to represent mobile context, the PRISSMA Context-Aware Presentation Layer for Linked Data, and the Shi3ld Context-Aware Authorization framework for Graph Stores.

The PhD Thesis has been co-supervised by Fabien Gandon and Ivan Herman, during my stint at Inria, in the WIMMICS team (Univertity of Nice-Sophia Antipolis).
