Abstract: Expert finding is a task of identifying a list of people who are 
considered experts in a given specific domain. Many previous works have 
adopted bibliographic records (i.e., publications) as a source of evidence for 
representing the areas of expertise [1,2]. In this paper, we present an 
expertise mapping approach based on a probabilistic keyword annotation model 
constructed from bibliographic data. To build the model, we use the Science 
Citation Index (SCI) database as the main publication source due to its large 
coverage on science and technology (S&T) research areas. To represent the 
expertise keywords, we use the subject category field of the SCI database 
which provides general concepts for describing knowledge in UT such as 
"Biotechnology & Applied Microbiology", "Computer Science, Artificial 
Intelligence" and "Nanoscience Nanotechnology". The keyword annotation 
model contains a set of expertise keywords such that each is represented with 
a probability distribution over a set of terms appearing in titles and abstracts. 
Given publication records (perhaps from different sources) of an expert, a set 
of keywords can be automatically assigned to represent his/her area of
