background : studies have shown that noise pollution has harmful effects on human health. the sound of traffic is the main source of noise pollution in cities. the purpose of this study was to determine noise pollution using a geographical information system (gis) in the main streets of kashan, iran. methods: in this study, 180 noise samples were collected from 20 regions of the main streets in...

Many documents that can be found in the World Wide Web include some kind of geographical information, often in an implicit way. The use of resources like gazetteers and geographical ontologies can improve the results in Geographical Information Retrieval. Unfortunately, the construction of such ontologies is a long and laborious process; therefore, building an ontology in a semi-automatical way...

SUMMARY Geoinformatics is described as a scientific and technical complex integrating the branch of scientific knowledge, the appropriate technology and the applied, or productive, activities concerned with the development and implementation of geographical information systems. Four stages of geoinformatics evolution are discussed, and its prospects are outlined in brief. 1. Introduction Geoinf...

This paper reports on the results of our experiments in the Monolingual English, German and Portuguese tasks and the Bilingual German topics on English collections, English topics on German collections and English topics on Portuguese collections tasks. Seven runs were submitted as official runs, four for the monolingual task and three for the bilingual task. We used the Terrier (TERabyte RetrI...

Toponym disambiguation or location names resolution is a critical task in unstructured text, articles or documents. Our research explores how to link ambiguous locations mentioned in documents, news and articles with latitude/longitude coordinates. We designed an evaluation system for toponym disambiguation based on annotated GEOCLEF data. We implemented a node-based approach taking population ...

In this paper, we describe a system that recognises place names in natural language text and produces geographic maps and animations showing the geographical coverage of texts about a certain subject as it changes over time. As the system is built to analyse texts in many different languages, it restricts the usage of linguistic analysis tools to the minimum. Instead, it relies on a gazetteer c...

Geographical information science can be defined as that branch of information science that deals with the geographical domain, or as the set of fundamental scientific questions raised by geographical information and the technologies that collect, manipulate and communicate it. Geographical information can reveal interesting patterns that point in some cases to causal mechanisms. The use of Glob...

In the 1970s, some people believed in using computers for making almost any information available to anyone and for supporting information exchange and discussions regardless of geographical distances. These ideas were, at that time, novel and revolutionary. Some people regarded these ideas as dangerous; for example, the Swedish Data Inspection Board (Datainspektionen) forbade people from stori...

Evaluating the impact of scholarly papers plays an important role for addressing recruitment decision, funding allocation and promotion, etc. Yet little is known how actual geographic distance influences the impact of scholarly papers. In this paper, we leverage the law of geographic distance and citations between different institutions to weight quantum Pagerank algorithm for objectively measu...
