三支概念的构建算法
Algorithm for constructing three-way concepts
摘要
Abstract
The theory of three‐way concept analysis is newly developed , but so far there is no concrete algorithm for constructing three‐way concepts . In order to solve this problem , a three‐way concept construction algorithm named CbO3C is firstly proposed in this paper . The CbO3C adopts the idea of the construction algorithm CbO of formal concepts in formal concept analysis . At the same time , in order to improve the efficiency and lower the memory overhead , the CbO 3C employs the partial closure canonicity test and inherited failure test to reduce the repeated computations of three‐way concepts , applies the reduction condition to filter the non‐core three‐way concepts , and implements set operations on the basis of bits . The experiments with UCI and random data sets show that the CbO 3C can correctly and efficiently calculate all core three‐way concepts of a formal context .关键词
