In this paper, we analyze factors that determine the check-in decisions of users on venues using a location-based social network dataset. Based on a Foursquare dataset constructed from Singapore-based users, we devise a stringent criteria to identify the actual home locations of a subset of users. Using these users' check-ins, we aim to ascertain the neighborhood effect on the venues visited, compared...
Mining frequent patterns is a crucial task in data mining. Most of the existing frequent pattern mining methods find the complete set of frequent patterns from a given dataset. However, in real-life scenarios we often need to predict the future frequent patterns for different tasks such as business policy making, web page recommendation, stock-market behavior and road traffic analysis. Predicting...
Kulasinghe and Bettayeb [Inform. Process. Lett. 53 (1995) 33-36] proved that the crossed cube CQn (a synonym called multiply twisted hypercube in that paper) fails to be vertex-transitive for n 5. In this paper, we study vertex-transitivity on folded crossed cubes FCQn and show that FCQn is vertex-transitive if and only if n ∊ {1, 2, 4}.
In this paper, we show how we can use Foursquare check-ins to understand the behavior of tourists that would be hard using traditional methods, such as surveys. For that, we analyze the behavior of tourists and residents in four popular cities around the world in four continents: London, New York, Rio de Janeiro, and Tokyo. We perform a spatio-temporal study of properties of the behavior of these...

Besides getting information from healthcare professionals and friends, 24% of adults also sought information or support from peers who have the same health condition. A major venue where...
At present, the smart city and big data have attracted much more attention from home and abroad. In this paper we take Guangzhou as an example to illustrate the role of big data in the construction of smart city. It focuses on the analysis of the present situation and some existing problems of Guangzhou smart city. Meanwhile, it mainly discusses the city planning, transportation, medical, education...
During recent years, there has been an increasing interest in the potential opportunities that can be attained with promoting Smart Cities; a concept that can be reached based on Information and Communication Technology (ICT). The Smart Cities concept is considered achievable by horizontal integration of a number of vertical industries in order to empower sustainability and improvements on quality...
Reducing the energy consumption of cellular wireless access networks is not only beneficial for the global environment but also makes commercial sense for telecommunication operators, our research focus on how to put forward a constructive energy saving method in the precondition of guaranteed service quality for customer. In this paper, we based on the signaling data and location data coming from...
This paper is to clarify the current status of smart systems and discuss the progressive formation of the privacy protection ecosystem for smart cities in Japan. The authors surveyed representative smart city projects, promotion groups, and several privacy protection platforms as case studies. As a result, the authors obtained the following three findings. First, Smart Grids and Smart Intelligent...
With the rapid development of the national economy and the speeding up of urbanization, the rail transport is gradually becoming the main way of the urban public transportation. The rail transit, as a kind of large capacity, high speed, safety and punctual transportation, not only improves the accessibility of the urban traffic, but also raises the new commercial circle. It brings a huge impact to...
During recent years, there has been an increasing interest in the potential opportunities that can be attained with promoting Smart Sustainable Cities (SSC); a concept that can be reached based on Information and Communication Technology (ICT). The SSC concept is then considered achievable by horizontal integration of participating industries in its ecosystem in order to empower sustainability. This...
The Nujiang is one of the regions where debris flow disasters occur frequently. For a long time, debris flow disasters have caused serious losses of life and property, so strengthening and controling the management of debris flow disasters and predict and alert debris flow disasters has become one of the main tasks for constructing and protecting ecological environment. Based on WebGIS, Internet of...

Two of the most important drivers of current telecommunication markets are the development of Rich Communication Services (RCS) and cloud computing. The challenges of delivering these new services on a cloud-based architecture are not only on the technical side, they also concern the definition of feasible business models for all the involved agents and the definition and negotiation of proper service...
The main idea behind this article is to propose technological tools in order to design, implement and deploy applications dedicated to smart-∗. Our approach is particularly relative to the smart cities domain, which is the most suitable field of experimentation for a wider domain called long-life applications. Currently, our computers and more generally, our mobile devices (tablets, smartphones) host...
Can cities be smart? In this article we define what a smart city is and formulate categories and indicators of smart and/or informational cities. Based on these measures, we investigate four Japanese cities as case studies that appear to be highly developed modern metropolises. We focus on infrastructures essential for an informational city as base for a ubiquitous, smart (in a narrow sense), creative,...
Information and Communication Technologies (ICTs) have been touted as means of increasing economic development by providing improvements in the lives of people where the use of technology leads to better livelihoods. Despite the high access and use of ICTs in the United States, high unemployment and poverty rates among Native Americans and African Americans continues to rise while deepening existing...
Carsharing has emerged as an alternative to vehicle ownership and is a rapidly expanding global market. Particularly through the flexibility of free-floating models, car sharing complements public transport since customers do not need to return cars to specific stations. We present a novel data analytics approach that provides decision support to car sharing operators -- from local start-ups to global...
