Service System Based on Formal Concept Analysis Theory

Formal concept analysis theory is a mathematical tool by establishing formal data structure to express the abstract relationship of concepts at different levels^[1], It has absolute advantages in expressing the dependence relationship, which is used to be visualized by Hasse graph, between concept data. Based on this theory, the paper designs and implements a service system, which realizes data analysis and information retrieval. Firstly, the formal context is built in specific field according to the functions. Secondly, formal concept analysis tools are used to construct concept lattices of context and extract association rules. Then, the whole service system is established based on association rules. Finally, the service system is applied to medical treatment, health exercise and academic research to realize the functions of blood test results analysis, human body composition monitoring results analysis, academic research direction retrieval and so on.
