We report our initial experiments on a computational approach to neighborhood detection from community-authored location annotated content. Automated discerning of context from the physical environment is an important challenge in the age of mobile computing, where context awareness can often be a critical component in the design of pervasive applications. Furthermore, defining the context of a...

The widespread proliferation of location-acquisition techniques and GPS -embedded mobile devices resulted in the generation of geo-tagged data at unprecedented scale and have essentially enhanced the user experience in locationbased services associated with social networks. Such locationbased social networks allow people to record and share their location and are a rich source of information wh...

Vehicular routing has been an extremely active research field in recent years with geo-routing protocols typically favoured over conventional topology based routing protocols due to their advantages in terms of scalability and lower overhead. Before a geo-routing protocol can transmit a packet, it must be aware of the position of the target node and is reliant upon a location service to supply ...

Expansion of business onto the Internet crosses national borders and creates uncertainty as to the propriety of jurisdiction by the courts of nations and their internal political units. Analysis of jurisdiction in United States law reveals that traditional rules provide guidance for resolving the question of constitutional jurisdiction in cases that cross geopolitical lines.

Plant-pathogen interactions are an important knowledge domain within plant biotechnology, both scientifically and in economic terms. Unlike other knowledge domains within life sciences, however, semantic technologies have not been used extensively to codify it, therefore, there is a lack of axiomatic models amenable to automated integration and inference. We present the Plant-Pathogen Interacti...

In this paper we investigate the contextualized representation of events. In particular, we re-interpret the formalization of events and situations adopted in the NewsReader Event and Situation Ontology (ESO) according to the notions of context and module proposed in the Contextualized Knowledge Repositories (CKR) framework. This contextualized formalization sets the basis for exploiting logica...

From the perspective of spatial information sharing and interoperation, the concept of geo-ontology has been proposed in this paper. At first, a brief introduction to the Geo-Ontology concept has been described and the hierarchical structure of geo-ontology has also been analyzed. Then, the traditional method of ontology construction has been discussed and the existing problems have also been s...

There has been a growing interest regarding generalized classes of distributions in statistical theory and practice because of their flexibility in model formation.Multiple imputation under such distributions that span a broader area in the symmetry–kurtosis plane appears to have the potential of better capturing real incomplete data trends. In this article, we impute continuous univariate data...

In this study, we investigate the geopolitical risk premium in commodity futures market. By estimating exposure of cross-sectional excess returns on a historical index, find that commodities with low-risk betas generate 9.05% higher annual risk-adjusted than those high-risk betas. The results indicate low-geopolitical-risk-related contracts require extra compensation by risk-averse investors du...

The effluent generated from a thermal power plant waste is a mixture of several chemicals and to identify the effect of these chemicals on soil, a case study on naturally contaminated sites at Al-Musayyib region, Hilla city in Iraq has been carried out. Soil and water samples were collected from the sites and analyzed to identify the pollutants and their effect on soil characteristics. Laborato...
