Heterogeneous data permeate in nearly every application and research field.Modeling and correlation analysis about heterogeneous data is the bottleneck of the conventional concept lattice as well as its various type of extended model.This paper presents a generalized concept lattice model by altering the definition of Galois connection function

f(A)

and

g(B)

given by Ganter and Wille

and discusses the ordering on heterogeneous attributes.After a survey of event-oriented knowledge representation

an event model formalized by generalized concept lattice is presented as an application

which is capable of dealing with different types of attributes and mining useful knowledge.This example gives a clue of generalized concept lattice model application in other fields.
