Towards the Use of Ontologies for Improving User Interaction for People with Special Needs

A Comparative Study of Ontology building Tools in Semantic Web Applications

“…Among many ontology languages, the Web Ontology Language (OWL) is the widely accepted as standard for representing and sharing knowledge in the Semantic Web context. [11] OWL is based on Resource Description Framework (RDF) and the DARPA Agent Markup Language (DAML) [12].OWL would use the RDF meaning of classes and properties (rdfs: Class, rdfs: subClassOf, etc.) and would add some very powerful modeling primitives to extend the expressiveness.…”

“…These tools are used for building a new ontology either from scratch or by reusing existing ontologies, which usually supports editing, browsing, documentation, export and import from different formats, views; libraries and they may have attached inference engines, etc. [20].…”

Accessibility through Preferences: Context-Aware Recommender of Settings

“…This hinders the possibility of generating personalised UIs, which are especially important for people with disabilities, as it involves auto-activating Assistive Technologies (AT). On the other hand, researchers [6] [7][8] [9] have produced fruitful results when adapting the UI to the user needs, whether in automatic or semi-automatic fashion, Nevertheless, in these cases the adaptation of the UI is focused on user needs leaving the context reduced to the device that the user is employing [10]. A good universal design [5] on the server side plus the correct AT with the best configuration of settings on the client side will allow individuals with disabilities to complete tasks without the intervention of third persons, providing full accessibility even in environments that are not owned by the user.…”

Personalized Handling of Semantic Data with MIG

“…The MIG visual impairment part has been inspired by the works of Karim & Tjoa [7], the Digital Item Adaptation (DIA) part of MPEG-21, and the Desease Ontology 6 . It is remarkable that most industrial standards, such as MPEG-7 and MPEG-21, provide detailed descriptions of the user and the user's environment, but using XML Schema to define their models.…”

“…MIG exploits this feature in order to detect the browser type, the Operating System, and the device's model when a device is used. MIG compares the UA string sent by the user's browser to WURFL 7 , a UA's repository. This repository stores information about 9000 devices, with hundreds of possible capabilities (e.g.…”
