Web-based delineation of imprecise regions

Web-based delineation of imprecise regions

This paper describes several steps in the derivation of boundaries of imprecise regions using the Web as the information source. We discuss how to use the Web to obtain locations that are part of and locations that are not part of the region to be delineated, and then we propose methods to compute the region algorithmically. The methods introduced are evaluated to judge the potential of the app...

Identifying imprecise regions for geographic information retrieval using the web

Answering Imprecise Queries over Web Databases

The rapid expansion of the World Wide Web has made a large number of databases like bibliographies, scientific databases etc. to become accessible to lay users demanding “instant gratification”. Often, these users may not know how to precisely express their needs and may formulate queries that lead to unsatisfactory results. For example, suppose a user wishes to search for sedans priced around ...

Delineation of demographic regions with GIS and computational intelligence

This paper presents a methodology for the creation of homogeneous demographic regions with geographical information systems (GIS) and computational intelligence. The proposed method is unsupervised fuzzy classification performed by neural networks using the fuzzy Kohonen algorithm. GIS technology offers a powerful set of tools for the input, management, and output of data, whereas computational...
