Geographic Information Retrieval (GIR) is an active and growing research area that focuses on the retrieval of textual documents according to a geographical criteria of relevance. In recent years, the IR research community has paid particular attention in IR systems that take into account temporal constraints. Temporal Information Retrieval (TIR) is a recent field which addresses the combinatio...

Geographical practice power is a key competency essential for students' overall development. It is, therefore, important to understand its concepts, contexts, and content. Practical activities following scientific operable principles in real geographical situations would enable students unleash their potential across the curriculum. The primary aim of this study was design validate conceptual, ...

Social scientists have long sought to understand the cultural production system. Such research elucidates the importance of the social milieu to cultural industries. We capture aggregate patterns of the social milieu and the geographical form it takes. We use a unique data set, Getty Images and geo-coded over 6000 events and 300,000 photographic images taken in Los Angeles and New York City, an...

This paper discusses a new approach to controlling for the environment when estimating efficiency. In response to the literature on the international comparison of bank efficiency, we draw the attention to a local dimension of comparison. By introducing geographical weights and estimating local frontiers for each US savings bank for the 2001-09 period, we find that the bank technical performanc...

BACKGROUND Geographical distribution of healthcare resources is an important dimension of healthcare access. Little work has been published on healthcare resource allocation patterns in China, despite public equity concerns. METHODS Using national data from 2043 counties, this paper investigates the geographic distribution of hospital beds at the county level in China. We performed Gini coeff...

Geographical curves are so involved in their detail that their lengths are often infinite or, rather, undefinable. However, many are statistically "selfsimilar," meaning that each portion can be considered a reduced-scale image of the whole. In that case, the degree of complication can be described by a quantity D that has many properties of a "dimension," though it is fractional; that is, it e...

Provision of big data analysis in a customer-friendly applicable form, with ease and affordable cost to a wide range of customers and businesses is still a big challenge for data scientists and engineers. In this study, present a framework for analysis and its visualization. We analyze Twitter messages related to a one-year span in a specific geographical area, Okinawa Island, in Japan. Our app...

Measuring how much cybercrime exists is typically done by first defining cybercrime and then quantifying how many cases fit that definition. The drawback is that definitions vary across countries and many cybercrimes are recorded as traditional crimes. An alternative is to keep traditional definitions of crime and quantify the amount of associated information and communication technologies (ICT...

Abstract Researchers in science and engineering have a long tradition of collaboration, and increasingly carry out these collaborations across geographical distance. Similar trends exist in industry, where virtual teams are increasing in frequency. While we know that such dispersed collaborations are difficult, there is growing evidence of success. The physical and biological sciences have led ...
