| Abstract(in English) | In recent years, due to the increasing popularization of various broadcast services, there is an increasing demand for filtering techniques. Although filtering systems that have been proposed filter data in their own ways, mathematical representation of these methods does not exist. Consequently, it is not possible to qualitatively evaluate various filtering methods, optimize processing methods in filtering, or design a declarative language for filtering processes. Therefore, in our previous work we have defined filtering function that represents filtering as a function, and clarified the relationship between the properties of different filtering. It is common to combine a few methods in current filtering systems in practice, but our previous work revealed only the properties of simple filtering function. In this paer, we clarify the properties of composite function of filtering function. In other words, we found out how the property of original function affects the composite function by qualitatively examining different compositions of functions. Accordingly, we can give a guideline for processing composite function. |
