Knowledge modelling techniques are widely adopted for designing knowledge-based systems (KBS) and these systems are important for knowledge management. This paper argues the need and importance of adopting Unified Modeling Language (UML) for knowledge modelling through the profile extension mechanism. KBS are developed using knowledge engineering (KE)(More)
Knowledge management is fast becoming a commercial necessity for many organizations, in order that they manage their intellectual assets and gain competitive advantage. To maximise that advantage, knowledge management needs to be available across the whole of the enterprise. Before a knowledge management system can be built, the knowledge that pervades the(More)
Purpose – The goal of this paper is to re-evaluate the role of knowledge-based systems (KBS) in knowledge management (KM). While knowledge-based systems and expert systems were widely used in the past, they have now fallen from favor and are largely ignored in the knowledge management literature. This paper aims to argue that several factors have changed(More)
Knowledge engineers have favoured a diagrammatic approach for developing knowledge-based systems by adopting those used in software engineering. However, these modelling techniques tend to be used in an ad hoc way and are highly dependent on the modelling experience of the engineers involved. This paper focuses on the use of the Unified Modeling Language(More)
Extraction, Transformation and Loading (ETL) represent a big portion of a data warehouse project. Complexity of components extensibility is a main problem in the ETL area, because ETL components are tightly-coupled to each others in the current ETL framework. The missing extensibility feature causes impediments to add new components to the current ETL(More)
This paper discusses extending the Unified Modelling Language by means of a profile for modelling knowledge-based system in the context of Model Driven Architecture (MDA) framework. The profile is implemented using the eXecutable Modelling Framework (XMF) Mosaic tool. A case study from the health care domain demonstrates the practical use of this profile;(More)
Securing the web against frequent cyber attacks is a big concern as attackers usually intend to snitch private information, financial information, deface and damages websites to prove their hacking capabilities. This type of vandalism may drive many corporations that conduct their business through the web to suffer financial and reputation damages. One of(More)
Electronic Medical Record (EMR) is the electronic middleman which allows users to access and retrieve patients' data, to review patients' medical history, and to facilitate the activation between patients and medical users. Considered as a developing country, Jordan still suffers from modernized management information systems that organize store, retrieve,(More)
