the development of a flexible and powerful knowledge Acquisition Framework for Text Classification and Information Extraction (KAFTIE), an incremental knowledge acquisition framework that strongly supports the rapid prototyping of new natural language processing (NLP) systems, was investigated. the rules in KAFTIE are stored in an exception structure as a Single Classification Ripple Down Rule tree. this framework is applied to tackle two different tasks of recognizing sentences that contain positive and negative attributions of a concept/term and extracting the concept/term. the results show that the knowledge bases built using the framework achieved precisions of at least 74% and recalls up to 88% on an unseen corpus.
In the context of a care network, we describe our method for reconstitution of a medical ontology via the translation of a medical database (DB) towards RDF(S) language. then we show how we extended this ontology, amo...

this paper describes our efforts to provide a collaborative problem solving architecture driven by semantic-based workflow orchestration and constraint problem solving. these technologies are based on shared ontologies that allows two systems of very different natures to communicate, perform specialised tasks and achieve common goals. We give an account of our approach for the workflow assisted collaboration with constraint solving capabilities. We found that systems built withsemantic (web) based technologies is useful for collaboration and flexible to enhance the system with specialised capabilities. However, much care must be exercised before correct semantics may be exchanged and collaborations occur smoothly.

there are shortcomings in using the web to publish information which are information overload and lost in hyperspace. the aim of the research is investigating how the semanticweb, open hypermedia, and adaptive hypermedia can enhance the adaptation, interoperability and sharing of knowledge components of various hypermedia systems, especially in the medical discipline. It also investigates how to create and manage adaptive web services by using ontologies and semantic properties for adaptation. the adaptive link services for the semanticweb is proposed.
Ontologies are widely used for capturing and organizing knowledge of a particular domain of interest. this knowledge is usually evolvable and therefore an ontology maintenance process is required to keep the ontologic...

We report the latest efforts of the Writing in the Context of knowledge (WiCK) project in investigating the use of semanticweb technologies in a business-type environment, where authors create and re-use knowledge-rich documents. To date, we have integrated an established commercial off-the-shelf office production environment withknowledgeweb services to assist authors in carrying out tasks in a business writing scenario.
We propose a semi-automatic method using information extraction (IE) techniques for generating ontology-based annotations for scientific articles, useful for biologists working in the biochip domain.

Augmenting web pages withsemantic contents, i.e., building a 'semanticweb', promises a number of benefits for web users in general and learners in particular. semantic technologies will make it possible to reason about the web as if it was one extended knowledge base, thus offering increased precision when accessing information and the ability to locate information distributed across different web pages. Moreover, it will become possible to develop a range of educational semanticweb services, such as interpretation or sensemaking, structure-visualization, support for argumentation, novel forms of content customization, novel mechanisms for aggregating learning material, and so on. In this paper we provide a framework to show how semantic Browsers which use ontologies to identity important concepts in a document as a means of providing access to associated educational services can be used in conjunction withknowledge Charts (ontologically permeated representations of a community's knowledge) in a process we call knowledge Navigation as an important new resource for learning.

One of the major challenges in semanticweb Service (SWS) technology is the improvement of the services matching process. this challenge is a critical issue to promote systems interoperability in the context of Scienti Network (SN), an internationalknowledge network in Science & Technology (S&T) [1]. We have been working on a framework to tackle this problem in the context of IRS-II SWS infrastructure. this framework (SeGOV), comprehends a set of ontologies to describe services in functional layers in order to allow their matching and improve their capabilities.
