Abstract
Many organizations have knowledge repository or data warehouses; however, information or
knowledge is scattered everywhere without proper use. Worse, the rapid growth of Internet
accelerates the creation of unstructured and unclassified information. It has resulted in
information overload. Though we can reach a flood of information through general-purpose
search engines, the effort of browsing through them is quite tedious and painstaking. Since most
of us are unable to utilize information effectively, there is a need for technology to solve this
issue. The purpose of this research is to explore text mining and data mining techniques to
address the problem. We discuss the major components of these knowledge computing techniques
required for building up a professional financial knowledge portal.
In the practical implementation, the laws and regulations related to securities and futures
markets were utilized to demonstrate the usage of SOM for topic categorization (topic map). We
also applied support vector machines in credit rating problems and stock market indices
prediction, with much better results than the traditionally statistics approaches and neural
network.
