The accelerated growth rate of the human intellectuality of any country warrants a rapid development of information infrastructural facility protecting their intellectual property. Basically determination of potential Geographical Indication (GI) is a necessity for timely protection of intellectual property of geographical characteristics. The process of determination and its subsequent filing ...

Geographical Information Systems (GIS) presents data-intensive environment for acquiring, processing and sharing geo-data among interested parties. In order to serve geographical information to users in such environment, Service Oriented Architecture (SOA) principles have gained great importance. In SOA-based systems, Information Services support the discovery and handling of these geospatial s...

Integration and interoperability is a basic requirement for geographic information systems (GIS). The web provides access to geographic data in several ways: on the one hand, web-based interactive GIS applications provide maps and routing information to end users; on the other hand, the data of some GIS can be accessed in a programmatic way using a web service. Thereby, the data is made availab...

For decades, geographical variations in cancer rates have been observed but the precise determinants of such geographic differences in breast cancer development are unclear. Various statistical models have been proposed. Applications of these models, however, require that the data be assembled from a variety of sources, converted into the statistical models’ parameters and delivered effectively...

In this paper a service-oriented architecture (SOA) is proposed to support the interaction with legacy Geographical Information Systems (GIS) and the implementation of value added data sharing services. In particular, we base our proposed architecture both on the standardization effort carried out by the Open Geospatial Consortium (OGC) and on current state-of-the-art Web Service middleware inf...

We have been developing web-based GIS/database (WebGD) applications that allow users to insert, query, update, and delete geographical features and the data associated with them from standard Web browsers. The code shared by these applications is organized as the WebGD framework. The behavior of the map interface of a WebGD application is defined by configuration files. We have built also the W...

This paper presents the method for retrieving and summarizing changes in topics from online resources. Users often want to know what are the major changes in their areas of interest. Usually, change detection applications are based on predetermined sets of web pages. User needs to provide the addresses of web pages in order to receive recent information about occurring changes. Our approach inv...

particulate and gaseous emissions of pollutants from industries and auto-exhausts are responsible for rising discomfort, aggravates respiratory and cardiovascular. in this study, a system for air quality information in tehran city has been developed, using an online web-based geographic information system. this web-based gis application allows users to recognize areas with a potential increase ...

A prototype Geographic Information System (GIS) framework has been developed to map, manage, and monitor sensors with respect to other geographic features, including land base and in-plant features. The GIS framework supports geographic placement and subsequent discovery, query, and tasking of sensors in a network-centric environment using Web services. The framework couples the GIS feature pla...

Most websites undergo a redesign from time to time. Along with the change of the appearance of the site comes a different document structure. Hence, redesigns can be detected by observing changes in the structural similarity of monitored HTML documents. Assuming further to monitor not a fixed document set but a series of the newest documents (e.g. provided by an RSS feed) transforms the task of...
