This paper is a contribution to formal ontology study. Some entities belong more or less to a class. In particular, some individual entities are attached to classes whereas they do not check all the properties of the class. To specify whether an individual entity belonging to a class is typical or not, we borrow the topological concepts of interior, border, closure, and exterior. We define a sy...

Culture and affect are closely tied domains that have been considered separately in HCI until now. After carefully reviewing research done in each of those domains, a formal ontology engineering approach brings us to identify and structure useful concepts for considering their interplay.

We investigate the effectiveness of OWL-DL ontologies in generating multiple choice questions (MCQs) that can be employed for conducting large scale assessments. The details of a prototype system called Automatic Test Generation (ATG) system and its extended version called Extended-ATG system are elaborated in this paper. The ATG system was useful in generating multiple choice question-sets of ...

Wayfinding in road networks is a hierarchical process. It involves a sequence of tasks, starting with route planning, continuing with the extraction of wayfinding instructions, and leading to the actual driving. From one task level to the next, the relevant road network becomes more detailed. How does the wayfinding process change? Building on a previous, informal hierarchical highway navigatio...

Ontology plays a vital role in sharing a common understanding of the domain among groups of people and provides terminology interpretable by machines. Recently, ontology has grown and continued to evolve constantly, but there are not many tools to provide an environment to support ontology evolution. This paper introduces a framework to support the management and maintenance leading to the evol...

This paper describes the development of the srBPA ontology, which is a formal ontology that conceptualizes the elements of the Riva-based business process architecture and the relationships between them. This ontology was instantiated using the UWE’s CEMS faculty administration case study in an attempt to assess the correctness and the usefulness of the developed ontology. The assessment reveal...

Due to the absence of a comprehensive knowledge system for modeling ocean circulation, there is ambiguity and diversity in semantic expression circulation. This makes it difficult organize share relevant spatiotemporal data effectively. paper addresses issue circulation by introducing ontological theory methodology based on analysis domain knowledge. Through conceptual relational characteristic...

Controlled languages (CLs) are ambiguity-free subsets of natural languages such as English offering a good trade-off between the formal rigor of ontology and query languages and the intuitive appeal of natural language. They compositionally map (modulo a compositional translation τ(·)) into (or express) formal query languages and ontology languages. Modulo compositionality, they inherit the com...

This paper details the design, implementation and evaluation of an ontology-based knowledge sharing tool. The system, “Squidz”, automatically classifies browsed web pages against an ontology, and allows users to share comments made about those pages to members of a community. As the user browses web pages, recommendations of relevant documents which have already been shared are produced, based ...
