摘要

形式概念计算是形式概念分析的重要研究内容之一.本文提出一种利用属性拓扑进行概念计算的可视化算法.该算法将属性拓扑以顶层属性为核心分解为若干子拓扑，利用可视化全路径搜索得到当前子拓扑的所有概念，进而得到该背景下的全概念集.该算法使概念计算精准并易于实现.

Abstract

The calculation of formal concepts is a very important part in the theory of formal concept analysis.This paper proposes a visualization algorithm of formal concept calculation that used the attribute topology of formal context.This algorithm puts the top attributes as the cores to decompose the topology into some sub-topologies

gets all the formal concepts by the visualization full path searching in present sub-topology

combine them to get a full set of concepts of the formal context.Through the analysis of the method

using the full path searching of the sub-topology to get formal concepts not only makes the calculation of formal concept simple and easy to operate

and will not result in lost or redundant computing formal concept.
