Evaluating Knowledge Representation and Reasoning Capabilites of Ontology Specification Languages
The interchange of ontologies across the World Wide Web (WWW) and the cooperation among heterogeneous agents placed on it is the main reason for the development of a new set of ontology specification languages, based on new web standards such as XML or RDF. These languages (SHOE, XOL, RDF, OIL, etc) aim to represent the knowledge contained in an ontology in a simple and human-readable way, as well as allow for the interchange of ontologies across the web. In this paper, we establish a common framework to compare the expressiveness of "traditional" ontology languages (Ontolingua, OKBC, OCML, FLogic, LOOM) and "web-based" ontology languages. As a result of this study, we conclude that different needs in KR and reasoning may exist in the building of an ontology-based application, and these needs must be evaluated in order to choose the most suitable ontology language(s)
Interoperability between classification systems using metadata
The First on-Line conference on Metadata and Semantics Research Conference (MTSR'05): Approaches to advanced information systems, 21-30 November 2005Metadata are structures which catalogue, classify, describe and articulate electronic information. The Subject element of Dublin Core is used for c1assification systems and subject headings. There are five ways of applying semantic interoperability: interoperability between controlled vocabularies in the same language; between controlled vocabularies in different languages and classification systems; between subject headings and c1assification systems; between c1assification systems; and between languages. The relations between diverse types of standards or systems present diverse difficulties. The electronic information container, which is Internet, guarantees the trend to try and achieve the interoperability of content analysis, whether it be between c1assification systems, or subject headings. The organisation of information in a physical format has transferred its organisational forms to the structuring of electronic information. The digital formal transforms the organisational form itself. If, in information the message is the medium, in organisation the structure is the medium.Publicad
Content creation and E-learning in Indian Languages : a model
In the era of E-publishing and E-learning, numerous
universities and cultural organizations around the world have launched initiatives to develop tools for multilingual learning and web publishing and have given preference to local content. India has different languages and different culture. Most of the knowledge and information related to people, culture, science and philosophy of India is available in Indian languages, which will be useful for learning and developing knowledge base. In India E-learning
systems and online courses are already started, but as a multi lingual country, which gives importance to education through regional languages, there should be facilities for multi lingual E-learning. This paper covers the issues of Indian language knowledge base/content base, its requirement, and its implication in e learning. An Integrated multi lingual E-learning system for India is proposed in this paper, where importance given to multi lingual course content creation
Stabilizing knowledge through standards - A perspective for the humanities
It is usual to consider that standards generate mixed feelings among
scientists. They are often seen as not really reflecting the state of the art
in a given domain and a hindrance to scientific creativity. Still, scientists
should theoretically be at the best place to bring their expertise into
standard developments, being even more neutral on issues that may typically be
related to competing industrial interests. Even if it could be thought of as
even more complex to think about developping standards in the humanities, we
will show how this can be made feasible through the experience gained both
within the Text Encoding Initiative consortium and the International
Organisation for Standardisation. By taking the specific case of lexical
resources, we will try to show how this brings about new ideas for designing
future research infrastructures in the human and social sciences
