Mining Multivariate Associations within GIS Environments

چکیده
As geospatial data grows explosively, needs for the incorporation of data mining techniques into Geographic Information Systems (GISs) are in great demand. Association rules mining is a core technique in data mining and is a solid candidate for the cause-effect analysis of large geospatial databases. It efficiently detects frequent asymmetric causal patterns in large databases. In this paper, we investigate a series of geospatial preprocessing steps involving data conversion and classification so that traditional boolean and quantitative association rules mining can be applied. We present a robust geospatial multivariate association rules mining framework for efficient knowledge discovery within data-rich GISs environments. The proposed approach can be integrated into traditional GISs using dynamic link library and scripting languages such as AVENUE for ArcView and MapBasic for MapInfo. Our framework is designed and implemented in AVENUE for ArcView GIS. Experiments with real datasets demonstrate the robustness and efficiency of our approach.

Prediction of Student Learning Styles using Data Mining Techniques
This paper focuses on the prediction of student learning styles using data mining techniques within their institutions. This prediction was aimed at finding out how different learning styles are achieved within learning environments which are specifically influenced by already existing factors. These learning styles, have been affected by different factors that are mainly engraved and found wit...

Geographical information systems (GIS) are a kind of location intelligence technology that supports systematic collection, integration, analysis and sharing of spatial data. They provide an effective tool for characterising and visualising geographical distributions of recyclable resources or materials dispersed across urban environments in what may be described as “urban mines”. As logistics c...

There is a long tradition of describing cities through a focus on the characteristics of their residents. A brief review of the history of this approach to describing cities highlights some persistent challenges. To fit within the constraints of widely used multivariate data reduction techniques and thematic cartography populations are classified. Historically, this classification has been guid...

Student populations tend to be located in particular spatial areas and within specific demographic settings. Spatial and nonspatial data such as the university's admission records, census data, transport network data, and university campus location data can be used to describe, explain, and predict university student admission patterns, thus provide information to assist the university with imp...

Overlaying maps using a desktop GIS is often the first step of a multivariate spatial analysis. The potential of this operation has increased considerably as data sources and Web services to manipulate them are becoming widely available via the Internet. Standards from the OGC enable such geospatial ‘mashups’ to be seamless and user driven, involving discovery of thematic data. The user is natu...
