Abstract (EN)
Research in social sciences typically involves collecting and analyzing a corpus of information annotated with time and source information. Such applications need to model when a given fact has happened, according to whom it has happ ened, and also when did a given source claim a given fact ; they may need to handle unknown, but constrained (bounded) moments in time. We present a generic source- centric temporal model, suited to the information modelling needs of social sciences. We present the conceptual model, a possible XML representation, and demonstrate its usefulness on data and queries of a real application . We explain the advantages of our model over those currently employed intemporal, probabilistic, and provenance databases.
