ConTag is an approach to generate semantic tag recommendations for documents based on Semantic Web ontologies and Web 2.0 services. We designed and implemented a process to normalize documents to RDF format, extract document topics using Web 2.0 services and finally match extracted topics to a Semantic Web ontology. Due to ConTag we are able to show that the information provided by Web 2.0 serv...

PM2.5 refers to particulate matter (PM) in air that is less than 2.5 μm in aerodynamic diameter, which has negative effects on air quality and human health. PM2.5 is the main pollutant source in haze occurring in Beijing, and it also has caused many problems in other cities. Previous studies have focused mostly on the relationship between land use and air quality, but less research has specific...

s. In addition to the didactic lectures, the meeting will also include over 90 poster presentations. The abstracts presented in this supplement issue to The Journal of Nuclear Medicine represent some of the most interesting ideas in molecular imaging research as applied to cancer biology and therapy. The abstracts are listed alphabetically by the last name of the presenting author, with the mai...

Exploring the complex effects of landscape patterns on ecosystem services (ESs) has become increasingly important in offering scientific support for effective spatial planning and management. However, there is a particular lack research nonlinear ESs scale dependence. Taking Huainan City (in China) as case study, this study adopted InVEST model to estimate four key including carbon storage (CS)...

Accurate digital mapping of farmland soil organic carbon (SOC) contributes to sustainable agricultural development and climate change mitigation. Farmland landscape pattern has changed greatly under anthropogenic influence, which should be considered an environmental variable characterize the impact human activities on SOC. In this study, we verified feasibility integrating patterns in SOC pred...
