HuTO: une Ontologie Temporelle Narrative pour les Applications du Web Sémantique: HuTO: une Ontologie Temporelle Narrative

National audienceThe temporal phenomena have many facets that are studied by different communities. In Semantic Web, large heterogeneous data are handled and produced. These data often have informal, semi-formal or formal temporal information which must be interpreted by software agents. In this paper we present Human Time Ontology (HuTO) an RDFS ontology to annotate and represent temporal data. A major contribution of HuTO is the modeling of non-convex intervals giving the ability to write queries for this kind of interval. HuTO also incorporates normalization and reasoning rules to explicit certain information. HuTO also proposes an approach which associates a temporal dimension to the knowledge base content. This facilitates information retrieval by considering or not the temporal aspect.Un défi majeur en informatique est la modélisation et le raisonnement sur les données temporelles. Ce travail est devenu encore plus important avec l'émergence du Web sémantique où de grandes quantités données hétérogènes sont manipulées. Ces données comportent souvent des informations temporelles informelles, semi-formelles ou formelles qui doivent être interprétées par les agents logiciels. Dans cet article nous présentons notre ontologie, Humain Time Ontologie (HuTO), une ontologie en RDFS pour annoter des ressources en RDF et représenter les expressions narratives temporelles. Une des contributions majeures de HuTO est la modélisation des intervalles non-convexes c'est-à-dire les intervalles répétitifs comme tous les mercredi mais également la possibilité d'écrire des requêtes sur ce type d'intervalle. HuTO intègre aussi des règles de normalisation et de raisonnement pour expliciter certaines informations temporelles. HuTO propose aussi une approche qui permet de garder distincte la dimension temporelle et les annotations du domaine métier. Cela facilite la recherche d'informations qu'elles soient temporelles ou non

Ontologies-Based Platform for Sociocultural Knowledge Management

International audienceIn this paper, we present a sociocultural platform aiming at persevering and capitalizing sociocul-tural events in Senegal. This platform relies on Semantic Web technologies. First, we discuss the two ontologies we provided to support our platform: an upper-level sociocultural ontology (USCO) and a human time ontol-ogy (HuTO). To build our upper-level ontology we proposed a methodology based on the theory of Russian psychologist Lev Vygotsky called "Vygotskian Framework". We also present how the upper-level ontology can be matched in the Linked Open Data (LOD) cloud. On the other hand, we present the Human Time Ontol-ogy (HuTO) of which major contributions are (i) the modeling of non-convex intervals (repetitive interval) like every Monday, (ii) representation deictic temporal expressions which form specific relations with time speech and (iii) qualitative temporal notions which are temporal notions relative to a culture or a geographical position. Finally, we discuss the platform designed on top of Semantic MediaWiki to apply our scientific contributions. indeed, the platform allows Senegalese communities to share and co-construct their sociocultural knowledge

How to Exploit the Digitalization Potential of Business Processes

Process improvement is the most value-adding activity in the business process management (BPM) lifecycle. Despite mature knowledge, many approaches have been criticized to lack guidance on how to put process improvement into practice. Given the variety of emerging digital technologies, organizations not only face a process improvement black box, but also high uncertainty regarding digital technologies. This paper thus proposes a method that supports organizations in exploiting the digitalization potential of their business processes. To achieve this, action design research and situational method engineering were adopted. Two design cycles involving practitioners (i.e., managers and BPM experts) and end-users (i.e., process owners and participants) were conducted. In the first cycle, the method’s alpha version was evaluated by interviewing practitioners from five organizations. In the second cycle, the beta version was evaluated via real-world case studies. In this paper, detailed results of one case study, which was conducted at a semiconductor manufacturer, are included
