Enhancing Information Quality through Semantic Approach in Health Information Retrieval

The availability of high quality, reliable health information can assist consumers in making more informed decisions about their healthcare. Concerns about the quality of health information have led to the development of numerous rating tools to evaluate health information on the web. These existing approaches are either based on keywords or terms to generate retrieval mechanisms. The objective of this research is to discover the appropriate approaches of health information retrieval to enhance information quality by using a semantic approach, called a concept based method. To satisfy this target, in this paper, we firstly discuss the importance on quality of health information on the web, analyse the existing health information retrieval systems and identified the gap in these systems, then propose a semantic approach for health information retrieval based on the ontology management. This approach attempts to overcome the major limitation of current health information systems by discovering semantic relations among query terms in the ontology so as to enhance the information quality.
