From Text to Databases: attribute grammar as database meta-model Open
We present a general methodology for structuring textual data, represented as syntax trees enriched with semantic information, guided by a meta-model G defined as an attribute grammar. The method involves an evolution process where both th…

Incremental Consistent Updating of Incomplete Databases Open
Efficient consistency maintenance of incomplete and dynamic real-life databases is a quality label for further data analysis. In prior work, we tackled the generic problem of database updating in the presence of tuple generating constraint…

Graph rewriting rules for RDF database evolution: optimizing side-effect processing Open
Purpose Graph rewriting concerns the technique of transforming a graph; it is thus natural to conceive its application in the evolution of graph databases. This paper aims to propose a two-step framework where rewriting rules formalize ins…

Specification of side-effect management techniques for semantic graph sanitization Open
The goal of the SENDUP project is to propose anonymisation mechanisms fordata organized as graphs with an underlying semantic. Such mechanisms trig-gers updates on the database. This deliverable presents the update approachand side-effect …

Graph Rewriting System for Consistent Evolution of RDF/S databases Open
This paper investigates the use of graph rewriting rules to model updates-instance or schema changes-on RDF/S databases which are expected to satisfy RDF intrinsic semantic constraints. Such databases being modeled as knowledge graphs, we …
