The hybrid fuzzy - SOEKS approach to the Polish internet mortgage market

The paper presents the hybrid fuzzy- SOEKS approach to the Polish Internet mortgage market, which is treated as an example of a fast changing market. Firstly, the market and market problems are described. Then, the first approach to the market problems is presented: the complete fuzzy model which was built basing on the rules. The fuzzy model is presented on one real data case. Next, the new approach, called Set of Experience Knowledge Structure (SOEKS) is adopted and presented basing on the same data. Instead of using data stored in the rules (fuzzy model), the market is presented using the experience stored in SOEKS. Finally, both approaches are compared with regard to their respective advantages and disadvantages, and some future works are described.
