The openness and accessibility of the Web has contributed greatly to its worldwide adoption. Uniform Resource Identifiers (URIs) are used for resource identification on the Web. A resource on the Web can be described in many ways, which makes it difficult for a user to find an adequate representation. This situation has motivated fruitful research...

The listing and automatic detection of ontology pitfalls are crucial in ontology engineering. Existing work mainly focused on detecting pitfalls in stand-alone ontologies. Here, we introduce a new categorization of ontology pitfalls: stand-alone ontology pitfalls, pitfalls in versioned ontologies and, pitfalls in ontology networks. We investigate p...

In the architecture, engineering and construction (AEC) industry stakeholders from different companies and backgrounds collaborate in realising a common goal being some physical structure. The exact goal is typically not known from the beginning, and throughout all design stages, new decisions are made - similarly to other design industries [1]. As...

Article
This paper aims to tackle issues related to the (re-)configuration of Smart Objects. These latter are composed specifically of smart sensors that embed basic sensors, a micro-controller and software snippets as well. In order to make this (re-)configuration feasible at runtime, we propose a semantic Web based approach that relies on a set of ontolo...

Conference Paper
Full-text available
Ontology evolution is the process of maintaining an ontology up to date with respect to the changes that arise in the targeted domain or in the requirements. Inspired by this definition, we introduce two concepts relatedto observe the impact and the adaptation to the evolution of an imported ontology. In the first one we target the evolution of an...

RDF aims at being the universal abstract data model for structured data on the Web. However, the vast majority of web services consume and expose non-RDF data, and it is unlikely that all these services be converted to RDF one day. This is especially true for sensors and other devices in the Web of Things, as most RDF formats are verbose while cons...

The W3C Linked Building Data on the Web community group discusses different potential patterns to associate values to properties of building elements. In this paper, we are interested in enabling a different value association method for these and other properties, to account for changes in time, or to annotate a value association with metadata such...

In this research, we investigate the problem of ontology construction in both automatic and semi-automatic approaches. There are two key issues for the ontology construction process: the cold start problem (i.e. starting the development of an ontology from a blank page) and the lack of availability of domain experts. We describe a functionality for...

Being able to describe quantity values and their units is a requirement that is common to many applications in several industrial sectors such as manufacturing, transport and logistics, personal and public health, smart cities, energy, environment, buildings, agriculture. Different ontologies have been developed to describe units, their relations,...

The Building Topology Ontology (BOT) was in early 2017 suggested to the W3C community group for Linked Building Data as a simple ontology covering the core concepts of a building. Since it was first announced it has been extended to cover a building site, elements hosted by other elements, zones as a super-class of spaces, storeys, buildings and si...
Technical Report
The Semantic Sensor Network (SSN) ontology is an ontology for describing sensors and their observations, the involved procedures, the studied features of interest, the samples used to do so, and the observed properties, as well as actuators. SSN follows a horizontal and vertical modularization architecture by including a lightweight but self-contai...

RDF aims at being the universal abstract data model for structured data on the Web. While there is effort to convert data in RDF, the vast majority of data available on the Web does not conform to RDF. Indeed, exposing data in RDF, either natively or through wrappers, can be very costly. Furthermore, in the emerging Web of Things, resource constrai...

Conference Paper
In the Resource Description Framework, literals are composed of a UNICODE string (the lexical form), a datatype IRI, and optionally, when the datatype IRI is rdf:langString, a language tag. Any IRI can take the place of a datatype IRI, but the specification only defines the precise meaning of a literal when the datatype IRI is among a predefined su...

Decentralising the power systems management brings clear advantages for the grid and for the stakeholders (consumers, generators, operational and management actors). The grid decentralisation can be achieved using microgrids. Some microgrids emerge worldwide, working as small energy islands. It is admitted that ontologies and open (Semantic) Web st...

Full-text available
We present our research in applying knowledge engineering to linguistic predicates and lexicographic definitions of the Meaning-Text Theory (MTT). We adopt a three-step methodology. 1. We first show how the MTT conceptualization should be extended to ease its formalization. We justify the need of defining a new graph-based deep semantic level. We d...

We are interested in the choice of a graph-based knowledge representation formalism that would allow for the representation, manipulation, query, and reasoning over linguistic knowledge of the Explanatory Combinatorial Dictionary (ECD) of the Meaning-Text Theory (MTT). We show that neither the semantic web formalisms nor the Conceptual Graphs Forma...

We are interested in bridging the world of natural language and the world of the semantic web in particular to support natural multilingual access to the web of data.

The Smart Applications REFerence (SAREF) ontology is a shared model of consensus that facilitates the matching of existing assets in the smart applications domain. SAREF provides building blocks that allow separation and recombination of different parts of the ontology depending on specific needs.
Project
Ontologies are at the heart of the Semantic Web, i.e., making data published on the Web comprehensible to intelligent added value services. Ontologies' consensual design ensures its usefulness and wide acceptance by service developers. The collaboration of ontology engineers, domain experts from multiple disciplines, and end-users is required for defining ontologies and populating them with instance data. Described domains are subject to changes, thus arises the need to evolve ontologies in order to have an adequate representation of the targeted domain. In this project, we aim at investigating several research issues associated to ontology evolution, mainly: 1) Taking advantage of different available knowledge bases to help to evolve ontologies. 2) Observe the adaptation to the evolution of connected ontologies. 3) Observe the set of bad practices that might occur during the evolution process of ontologies.
