This paper describes the system submitted to the TAC 2013 entity linking task of the Knowledge Base Population track. The core of the approach is probabilistic information retrieval over a search index of the knowledge base, including the text of Wikipedia. The retrieval results are further reranked using a supervised learning-to-rank model. The submission this year builds on the neighborhood a...

Cities accommodate population growth both through the densification of their existing footprints and expansion into rural peripheries. In recent decades, most has been accommodated urban expansion. Global South, where now takes place, occurs in a haphazard, unplanned manner, making cities less productive, inclusive, resilient, sustainable. This editorial provides non-technical introduction to s...

Analyzing spatiotemporal characteristics of the historical urbanization process is essential in understanding the dynamics of urbanization and scientifically planned urban development. Based on historical urban area maps and remote sensing images, this study examined the urban expansion of Shenyang from 1910 to 2010 using area statistics, typology identification, and landscape metrics approache...

This study analyses the expansion of urban growth and land cover changes in five Saudi Arabian cities (Riyadh, Jeddah, Makkah, Al-Taif and the Eastern Area) using Landsat images for the 1985, 1990, 2000, 2007 and 2014 time periods. The classification was carried out using object-based image analysis (OBIA) to create land cover maps. The classified images were used to predict the land cover chan...

Sustainable urban development is a focus of regional policy makers; therefore, how to measure and understand urban growth is an important research topic. This paper quantified the amount of urban growth on land use maps that were derived from multi-temporal Landsat images of Jiaxing City as a rapidly-growing city in Zhejiang Province from 2000–2015. Furthermore, a new approach coupled the heuri...

This study analyzes the characteristics of land use/land cover change in Jordan’s Irbid governorate, 1984–2018, and predicts future land use/land cover for 2030 and 2050 using a cellular automata-Markov model. The results inform planners and decision makers of past and current spatial dynamics of land use/land cover change and predicted urban expansion, for a better understanding and successful...

Africa has high biodiversity and is rapidly urbanizing. However, there is limited understanding of how urban expansion in Africa is likely to affect its habitats and biodiversity. Little urban ecological research has been done in Africa. This study needs to think ahead as Africa move into the “urban age” it is critical to inform the public on the importance of urban environment...

China has undergone economic transition characterized by marketization, globalization and decentralization, which has resulted in profound change in land use and urban space. This paper integrates globalization, institutional change, and China's economic transition to better understand urban land expansion in China. We use land use survey data in Jiangsu province at the county level to shed the...
