From Knowledge Visualization Techniques to Trends in Ubiquitous Multimedia Computing

With recent flourishing of wireless communication infrastructures such as 3G, WiMax and RFID, ubiquitous multimedia computing becomes a major focus in scientific research. It would be helpful if we are able to trace the latest development in this particular science and technology field. However, it is a challenging task to swiftly and efficiently filter out information for elevating scholastic research efficiency in large volume of information. In this paper, different perspectives and methods were introduced to analyze leading research theme in particular in ubiquitous computing field. Three knowledge visualization techniques are presented to display research directions by clustering scientific papers taken from the ISI web (CiteSeer papers): factor analysis, pathfinder network and context-based ontology. The results obtained show that recent popular research towards to pursue ubiquitous applications in particular in m-health. The beneficiary of this paper could be for someone new to a specific domain in research study, who wishes to analyze and understand current development status of intended research study field.
