Mining Human-Place Interaction Patterns from Location-Based Social Networks to Enrich Place Categorization Systems

by Yingjie Hu, Grant Mckenzie, Krzysztof Janowicz, Song Gao
"... Abstract. Place categorization plays an important role in location-based services as well as more recently in place-based geographic in-formation systems. Traditionally, such categorization systems are often designed following a top-down approach in which a group of experts or users assign a place t ..."

of this perception are captured by location-based social network platforms. Contributions to these platforms, such as check-ins and reviews, enable a bottom-up approach to place categorization based on the actual interaction between humans and places. In this short pa-per, we outline selected advantages of a hybrid

Materials for an exploratory theory of the network society.

"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

Expertise identification using email communications

by Christopher S. Campbell, Paul P. Maglio, Alex Cozzi, Byron Dom - In CIKM ’03: Proceedings of the twelfth international conference on Information and knowledge management , 2003
"... A common method for finding information in an organization is to use social networks—ask people, following referrals until someone with the right information is found. Another way is to automatically mine documents to determine who knows what. Email documents seem particularly well suited to this ta ..."

to this task of “expertise location”, as people routinely communicate what they know. Moreover, because people explicitly direct email to one another, social networks are likely to be contained in the patterns of communication. Can these patterns be used to discover experts on particular topics

Mining User Similarity from Semantic Trajectories

by Josh Jia-ching Ying, Eric Hsueh-chan Lu, Wang-chien Lee, Tz-chiao Weng, Vincent S. Tseng - In Proceedings of ACM SIGSPATIAL International Workshop on Location Based Social Networks , 2010
"... In recent years, research on measuring trajectory similarity has attracted a lot of attentions. Most of similarities are defined based on the geographic features of mobile users ’ trajectories. However, trajectories geographically close may not necessarily be similar because the activities implied b ..."

Network structure mining: locating and isolating core members in covert terrorist networks

by Muhammad Akram Shaikh, Wang Jiaxin - WSEAS Transactions on Information Science and Applications , 2008
"... Abstract: Knowing patterns of relationship in covert (illegal) networks is very useful for law enforcement agencies and intelligence analysts to investigate collaborations among criminals. Previous studies in network analysis have mostly dealt with overt (legal) networks with transparent structures. ..."

Unlike conventional data mining that extracts patterns based on individual data objects, network structure mining is especially suitable for mining a large volume of association data to discover hidden structural patterns in criminal networks. Covert networks share some features with conventional (real
