Using Geographic Ontologies and Geo-Characterization to Represent Geographic Scenarios

Applying Geo-feedback to Geographic Information Retrieval

In this paper we identify location names that appear in queries written in Indonesian using geographic gazetteer. We built the gazetteer by collecting geographic information from a number of geographic resources. We translated an Indonesian query set into English using a machine translation technique. We also made an attempt to improve the retrieval effectiveness using a query expansion techniq...

Using Ontologies for Integrated Geographic Information Systems

Today, there is a huge amount of data gathered about the Earth, not only from new spatial information systems, but also from new and more sophisticated data collection technologies. This scenario leads to a number of interesting research challenges, such as how to integrate geographic information of different kinds. The basic motivation of this paper is to introduce a GIS architecture that can ...

Using Ontologies for Geographic Information Integration

Enhancing the Process of Knowledge Discovery in Geographic Databases Using Geo-Ontologies

This chapter introduces the problem of mining frequent geographic patterns and spatial association rules from geographic databases. In the geographic domain most discovered patterns are trivial, non-novel, and noninteresting, which simply represent natural geographic associations intrinsic to geographic data. A large amount of natural geographic associations are explicitly represented in geogra...

Geographic Ontologies, Gazetteers and Multilingualism

Different languages imply different visions of space, so that terminologies are different in geographic ontologies. In addition to their geometric shapes, geographic features have names, sometimes different in diverse languages. In addition, the role of gazetteers, as dictionaries of place names (toponyms), is to maintain relations between place names and location. The scope of geographic infor...
