Interests

Dr. Cheah Yu-N’s main interest in this area is to explore how computer science techniques can be employed to realise a variety of knowledge management processes, i.e. to create, identify, collect, organise, share, adapt, and apply knowledge. This effort translates into various initiatives such as the following: Tacit knowledge acquisition, Knowledge discovery and data mining, Knowledge organisation, Intelligent agents 
Coalition formation, Automatic question answering, Personal knowledge publishing, and Knowledge email.

A majority of the implementations are in the form of client-server applications. This is in line with the widespread adoption of intranet- and internet-based environments in many organizations.

Health Informatics

Dr. Cheah’s interest in this area focuses on adapting computer science and knowledge management techniques for healthcare purposes. In view of this, some of the research topics can be adapted into other domains besides healthcare. In general, the various research outputs can be incorporated into a platform that aims to provide a variety of processors and services for healthcare knowledge management. Some of the areas being explored are as follows: Dynamic healthcare planning, Healthcare decision support, Clinical case acquisition, and Healthcare portals.
