摘要: 挖掘隐藏在地理信息系统(GIS)的空间数据中的知识是GIS研究领域和数据挖掘领域的重要方向。概念格是关联分析的重要技术之一。为了提高关联规则的挖掘速度,提出了一种基于增量式算法的概念格构造算法,通过用比较概念外延的方法建格,同时在建格过程中引入支持度约束,使得概念格的建格速度得到提高,并使建成的格具有高度的约简性,让后续的规则挖掘变得更容易。将所提算法应用于GIS的空间数据挖掘,取得了切实可行的应用结果。

Abstract: Mining the hidden knowledge in the spatial data of Geographic Information System (GIS) is an important direction in the study fields of GIS and data mining. The technique of concept lattice is very important in finding association rules. In this paper, an algorithm of building concept lattice based on incremental method was proposed to improve the speed of building lattice by comparing the extent of the concept and introducing support constraint. It could also simplify the lattice and make it easier to mine rules. To expand the application of the algorithm, it was applied in finding association rules of the spatial data in GIS and got practicable application result.

Key words: Geographic Information System (GIS), spatial database, data mining, association rule, concept lattice
