Urban Interactive

Valentina Croci profiles the work of entertainment design office Area/Code which foregrounds urban locations in its games. As Croci explains the approach of this NewYork-based partnership, which delivers sat nav-inspired gaming to the mobile phone, demonstrates an inherent understanding of the importance of the physical in enhancing the imaginary.

Wearable Technologies,Portable Architectures and the Vicissitudes of the Space Between

The omnipresence of the iPod and mobile phone has ensured portable and wearable technologies' highly privileged position in contemporary society. They are at the top of the pile where conspicuous consumption is concerned - you only have to visit an Apple store on a Saturday afternoon to witness the degree to which this highly sought-after gadgetry has become subject to consumer frenzy and speculation. Here, Despina Papadopoulos reviews the particular social and cultural impact of wearable devices. She also welcomes in a new generation of interactive designers who are investigating the human and emotional potential of emergent technologies. Copyright © 2007 John Wiley & Sons, Ltd.     

iPastoral

Architectural theorist and educator Mark Morris parallels the 18th-century enthusiasm for the Claude glass, a black mirror that framed and filtered views into painterly landscapes, with the current infatuation for a similarly small shiny black device with a capacity for taking picturesque images.

Darwin Among the Machines

In the mid-19th century, Samuel Butler in his article ‘Darwin among the Machines’ provided a theory for the iterative development of machines over time. Here, London-based architect, theorist, editor and writer Jack Self casts ‘the modern city’ as ‘a multiplex superposition of network infrastructures’, defined by hierarchical systems of information and material exchange. He argues that current informational technologies have the power to conversely hyper-centralise or hyper-localise the city, thus either encouraging disengagement or nurturing engagement with the emergent social practices of the city's inhabitants.     

Personalized Tag Recommendation Using Social Influence

Tag recommendation encourages users to add more tags in bridging the semantic gap between human concept and the features of media object,which provides a feasible solution for content-based multimedia information retrieval.In this paper,we study personalized tag recommendation in a popular online photo sharing site - Flickr.Social relationship information of users is collected to generate an online social network.From the perspective of network topology,we propose node topological potential to characterize user’s social influence.With this metric,we distinguish different social relations between users and find out those who really have influence on the target users.Tag recommendations are based on tagging history and the latent personalized preference learned from those who have most influence in user’s social network.We evaluate our method on large scale real-world data.The experimental results demonstrate that our method can outperform the non-personalized global co-occurrence method and other two state-of-the-art personalized approaches using social networks.We also analyze the further usage of our approach for the cold-start problem of tag recommendation.     

VGI集成于中文数字地名词典的研究

提出将自发地理信息（VGI）集成到中文数字地名词典（CDG）的架构。在构建VGI数据爬取模型（VDCM）和地名本体的基础上, 针对从VGI数据中提取地名信息过程中出现的地名geo/geo歧义（多个地理位置对应同一地名）、地名与经纬度匹配错误、多个资源对应同一地名等问题提出相应的解决方案：使用上级行政区划名排歧、参考行政区划本体层次筛除错误地名标签、对同一地名的多个资源进行空间聚类获得唯一的经纬度, 并总结该架构能有效地解决CDG不支持空间推理、数据孤立以及数据维护、更新受限等问题, 提出未来的工作围绕修正错误的地名标签、构建信任模型及将VGI集成于分布式CDG展开。
