Current research in health informatics should provide the techniques and tools that will enable the development of an efficient hospital information ecosystem. The different information systems (IS) will be able to efficiently communicate with each other and provide a patient oriented environment. It is thus important to provide a clear understanding of(More)
The Web is currently characterised by user contribution. As a result, content is generated in an uncontrolled way leading to the so-called “information overload”. The role of information filtering techniques and recommender systems is to give a solution to this problem by taking into account user preferences, and/or other context of information to present(More)
Patient information in healthcare organizations is distributed across several systems and data silos. Clinicians make decisions based on data in patient health records. Improving the efficiency of decision-support requires collective knowledge of all patient information. The classical approach of linking patient data from many databases into one data(More)
This study introduces the necessary ontological redesign regarding patient-oriented frameworks. Different national healthcare frameworks around the world as well as semantic gaps have been discovered and demonstrate the need for a new healthcare management framework. This study's Patient-Oriented Management and Reporting framework (POMR framework) will(More)
Current researches in health informatics provide the techniques and tools enabling the development of efficient hospital information ecosystem that can be made to exchange data with each other and thus provide a coherent patient oriented environment. In order to achieve this desired HIS interoperability, it is important to provide a clear understanding of(More)
Sensors, actuators and event sensors are the major types of transducers recognized by the IEEE 21451 standards for Smart Transducers. These contain information embedded in the Transducer Electronic Data Sheets (TEDS) that help describe the transducer and identify it in a network. Advancement in sensor and information technologies has led to various designs(More)
Nowadays, more than ever, it is evident that we need a series of technological and methodological techniques in order to improve on the systems analysis and design (SAD) of any informational system. Recently, there is a huge demand to create domain vocabularies and semantics that along with cognition are to describe the information of any domain in the form(More)
Information filtering and recommender systems exploit various techniques to deal with the information overload problem. One popular technique for making recommendations is based on trust statements between users in a social network. Yet explicit trust statements are usually very sparse leading to the need for expanding the trust networks by inferring new(More)
