Onto-CDS: Medical decision support with timely updated knowledge

In medical domain DSSs are known as Clinical Decision Support System (CDSS) [1]. It is defined as software that helps in clinical decision-making. It matches the computerized clinical knowledge base with the individual patient´s symptoms or the medical test results. After that the specific assessment or recommendations are then presented to the medical doctor for the decision. However, construction, maintenance and timely updating of such CDS have become challenges due to many reasons. Among others reasons, since body of knowledge in medicine is constantly updated, computer programmers are unable to timely update a CDS. Thus it is undisputed that automated solution for maintenance and updating of CDS solutions is of paramount importance. In this context, the concept of Ontology has gone beyond traditional data modelling approaches such as Entity-Relationship (ER) and the Object Oriented Modelling. More importantly, Ontology can automatically extract the up to date knowledge from the Internet and update the knowledge base of CDS.
