Représentation sémantique multilingue, multiculturelle et temporelle des relations interpersonnelles, appliquée à une prothèse de mémoire

Abstract : In this thesis, we propose a knowledge base for a "smart" memory prosthesis, called CaptainMemo, which aims to help Alzheimer's patients to overcome their memory impairments. This knowledge base is built over the temporal, multicultural and multilingual PersonLink ontology. This ontology gives the memory prosthesis a rigorous, multilingual and temporal semantic representation of interpersonal relationships. The PersonLink ontology is dereferenceable and available in the Linked Data. Multilingualism and temporal representation are two major research topics in computer science and in the Semantic Web in particular.Multilingualism applied to the representation of interpersonal relationships requires specific treatment because it is linked to multiculturalism. In addition, the transition from one culture / language to another is a major research problem. Indeed, literal translation is not always allowed, especially when it comes to interpersonal relationships, because they are culturally dependent. In this context, we propose an approach allowing the representation of ontologies in several cultures / languages. This approach, based on a translation algorithm, allows the transition from one culture / language to another by making a cultural translation rather than a literal one. Thus, by adopting this approach, our PersonLink ontology allows an exact representation of interpersonal relationships, because it takes into consideration the cultural aspect for the definition of each relationship, and assigns the appropriate term according to the language related to this culture. Interpersonal relationships are governed by rules and constraints that define them according to each culture, these constraints are represented semantically in the PersonLink ontology using OWL2. However, it is difficult to consider these constraints when introducing the temporal dimension to represent the time intervals of these interpersonal relationships, especially when these are diachronic and their time intervals are qualitative. Indeed, the legacy models and solutions make it possible to make a temporal representation of the time intervals (e.g. 4D-Fluents), and to link between these time intervals (e.g. Allen Relations), but do not take into account the semantics constraints of interpersonal relationships. In this context, we propose an approach that allows a semantic representation, based on OWL2 constraints, for the representation of qualitative time intervals. Finally, to deal with the intelligence of the CaptainMemo memory prosthesis, we propose an approach for reasoning over time intervals. In this approach we introduce a set of SWRL rules to assert inferred temporal Allen relationships, allowing reasoners, such as Pellet that supports DL-Safe rules, to be used for the inference and the verification of consistency over the temporal relationships between different time intervals. Thus, the table of compositions of the relations between time intervals has been considerably reduced, since it is based on a tractable set of these relations, and, consequently, the processing time of the reasoning becomes shorter.
