ROSA is a Learning Object (LO) repository system with semantic access, which enables the management of LOs. LO is a collection of reusable material used to support learning, characterized by a set of metadata descriptors. LOs are accessed in a contextualized way, determined by semantic associations between them. This paper presents ROSA+, a system extension that aims at deducing additional sema...

The representation of temporal information has been in the center of intensive research activities over the years in the areas of knowledge representation, databases and more recently, the Semantic Web. The proposed approach extends the existing framework of representing temporal information in ontologies by allowing for representation of concepts evolving in time (referred to as “dynamic” info...

Rules are increasingly becoming an important form of knowledge representation on the Semantic Web. There are currently few methods that can ensure that the acquisition and management of rules can scale to the size of the Web. We previously developed methods to help manage large rule bases using syntactical analyses of rules. This approach did not incorporate semantics. As a result, rule categor...

shared ontologies and reasoning strategies (generated by the framework and semantically represented), which can be accessed and re-used by other applications. This paper proposes a semantic framework built on multidimensional ontological planes for the design of adaptive systems. The core of the framework is composed by three matrices whose different planes contain the ontological representatio...

This paper presents our experience regarding the creation of 3D semantic facility model out of unorganized 3D point clouds. Thus, a knowledge-based detection approach of objects using the OWL ontology language is presented. This knowledge is used to define SWRL detection rules. In addition, the combination of 3D processing built-ins and topological Built-Ins in SWRL rules aims at combining geom...

The initial Web was called static web because only it allowed users to follow clickable links in a bid to view information. That primitive Web platform provided means for propagating electronic commerce (E-commerce). However, the Semantic Web Initiative and its supporting technologies further improved the Web, which have enhanced E-commerce. Some of the Semantic Web technologies that have been ...

Nowadays, data integrity has become a critical issue in the pharmaceutical regulatory landscape, one that requires to be compliant ALCOA principles (i.e., must Attributable, Legible, Contemporaneous, Original, and Accurate). In this paper, we propose method which exploits semantic web technologies represent pharma manufacturing unified manner evaluate systematic their compliance. To purpose, co...

The Region Connection Calculus (RCC), and particularly its RCC8 subset, have been extensively studied and used for qualitative spatial reasoning. Some sets of computational operations have also been defined for topological relations, as the CM8 set, that allows to compute the RCC8 relationships on raster images. In this paper, we propose a reified representation of the RCC8 spatial relationship...
