Oyster – Sharing and Re-using Ontologies in a Peer-to-Peer Community
In this paper, we present Oyster, a Peer-to-Peer system for
exchanging ontology metadata among communities in the
Semantic Web. Oyster exploits semantic web techniques in data
representation, query formulation and query result presentation to provide an online solution for sharing ontologies, thus assisting researchers in re-using existing ontologies

The Distributed Ontology Language (DOL): Use Cases, Syntax, and Extensibility
The Distributed Ontology Language (DOL) is currently being standardized
within the OntoIOp (Ontology Integration and Interoperability) activity of
ISO/TC 37/SC 3. It aims at providing a unified framework for (1) ontologies
formalized in heterogeneous logics, (2) modular ontologies, (3) links between
ontologies, and (4) annotation of ontologies. This paper presents the current
state of DOL's standardization. It focuses on use cases where distributed
ontologies enable interoperability and reusability. We demonstrate relevant
features of the DOL syntax and semantics and explain how these integrate into
existing knowledge engineering environments.Comment: Terminology and Knowledge Engineering Conference (TKE) 2012-06-20 to

Adaptive courseware design based on learner character
During last decade, a great advance has been done in both theoretical research and
software construction of Adaptive Hypermedia Systems (AHS). The article discusses
the practical approach taken for authoring and instructional design of adaptive
courseware based on learner character, namely learner goals and preferences,
learner style, and learner performance and satisfaction level. This approach is
adopted at pilot test of ADOPTA - adaptive technology-enhanced platform for
edutainment. The authoring process relies strongly on an enhanced learning object
metadata support, where learning styles are used for adaptive navigation within the
narrative storyboard graph. On other side, both learner knowledge and satisfaction
level determine adaptive content selection
Storyboard Design for Adaptive E-learning Based on Learning Styles
The article discusses the methodology taken for instructional design of adaptive courses based on learner character such as learner goals and preferences, learner style and, as well, learner performance and satisfaction level. The adaptive course is presented by storyboard graph, whose nodes are pages with learning content, but paths in it represent different pedagogical strategies set by the instructor. This approach was used in ADOPTA - adaptive technology enhanced platform for edutainment, in order to develop a course on XML. It is consistent with a new conceptual model for adaptive hypermedia and uses a family of Honey and Mumford learning styles
Software Construction of an Authoring Tool for Adaptive E-learning Platform
In last decade, more and more platforms for elearning
content delivery provide adaptability towards
learners goals, styles and performance. Usually, such
platforms rely on own authoring tool or use external
one in order to create learning materials. Usually,
these tools follow modern e-learning standards but are
rather complicated to be used and miss
interoperability features. In this paper, we present
software construction of an authoring tool, which is a
part of a platform for building edutainment (education
plus entertainment) services – ADOPTA (ADaptive
technOlogy-enhanced Platform for eduTAinment). This
authoring tool is designed by using Java EE 5 platform
and provides inheritance mechanisms for learning
object metadata descriptions, metadata for semantic
ontology graphs, and good integration with instructor
tool for creation of adaptive courseware
Building an ontology catalogue for smart cities
Apart from providing semantics and reasoning power to data, ontologies enable and facilitate interoperability across heterogeneous systems or environments. A good practice when developing ontologies is to reuse as much knowledge as possible in order to increase interoperability by reducing heterogeneity across models and to reduce development effort. Ontology registries, indexes and catalogues facilitate the task of finding, exploring and reusing ontologies by collecting them from different sources. This paper presents an ontology catalogue for the smart cities and related domains. This catalogue is based on curated metadata and incorporates ontology evaluation features. Such catalogue represents the first approach within this community and it would be highly useful for new ontology developments or for describing and annotating existing ontologies
Developing Ontology for Malaysian Tourism
This project describes on the development of Malaysian Tourism Ontology and the
importance of ontology to make knowledge assets intelligently accessible to people in
organizations. Ontology is a long-lived conceptual model that can be used in multiple
applications, providing good opportunities for reuse and interoperability. Ontology
defines a common vocabulary for researchers who need to share information in a domain.
It includes machine-interpretable definitions of basic concepts in the domain and
relations among them. The purpose ontology being develops because to share the
common understanding of the structure of information among people and among
software agents. It can enable re-use of domain knowledge and can avoid "re-inventing
the wheel". If the ontology already exists, it cut short the development part and just
makes use of it. Ontology is aim to introduce standards to allow interoperability in order
to create a machine readable. Moreover, ontology is used to capture knowledge, create a
shared understanding between humans and for computers, make knowledge machine
processable and makes meaning explicit by definition and context. Domain knowledge
need to be analyzed in order to make it more meaningful and towards creating a machine
readable program. This ontology is created using Protege 3.2 Beta, an integrated software
tool used to develop knowledge-based system that includes a knowledge base about a
domain and programs that include rules for processing the knowledge and for solving
problems relating to the domain. This application is developed using Protege-3.2, an
advanced technology tool use in problem solving and decision-making in a particular
domain or field of knowledge
Ontology Repositories
The growing use and application of ontologies in the last years has led to an increased interest of researchers and practitioners in the development of ontologies, either from scratch o by reusing existing ones. ..
