ADVANCED PERSONALIZATION OF LOCATION BASED SERVICES

This article explores possible solutions for improving Location Based Services (LBS). For the purpose of this paper context, user profile, previous choices and the choice profiles of similar users are aspects taken into consideration. A possible implementation of an LBS system, in the form of a public transport route finding application based on genetic algorithms is also presented. The proposed application uses semantic tagging to integrate data from multiple sources and sensors into a single interpretation.Knowledge Management, Geographic Information Systems, Location-based Services, Semantic Web

Situation fencing: making geo-fencing personal and dynamic

Geo-fencing has recently been applied to multiple applications including media recommendation, advertisements, wildlife monitoring, and recreational activities. However current geo-fencing systems work with static geographical boundaries. Situation Fencing allows for these boundaries to vary automatically based on situations derived by a combination of global and personal data streams. We present a generic approach for situation fencing, and demonstrate how it can be operationalized in practice. The results obtained in a personalized allergy alert application are encouraging and open door for building thousands of similar applications using the same framework in near future

Issues in the Development of Location Privacy Theory

Issues in the development of location privacy theory are identified and organized based on both technological considerations and more general privacy theories. Three broad categories containing six issues are described: location (including sensing methods and location properties), privacy (including definition and subject identification), and information flows (from location information acquisition through storage, use, and sharing). An influence diagram model is presented which relates these issues in context and may serve as a basis for further theory development, empirical research, and public policy discussion

Sensing Landscape History with an Interactive Location Based Service

This paper introduces the STEAD approach for interpreting data acquired by a “human sensor”, who uses an informal interactive location-based service (iLBS) to sense cultural-historic facts and anecdotes of, and in the landscape. This user-generated data is collected outdoors and in situ. The approach consists of four related facets (who, what, where, when). Three of the four facets are discussed and illustrated by user generated data collected during a Dutch survey in 2008. These data represent the personal cultural-historic knowledge and anecdotes of 150 people using a customized iLBS for experiencing the cultural history of a landscape. The “who” facet shows three dominant mentality groups (cosmopolitans, modern materialists and post modern hedonists) that generated user content. The “what” facet focuses on three subject types of pictures and four picture framing classes. Pictures of the place type showed to be dominant and foreground framing class was slightly favourite. The “where” facet is explored via density, distribution, and distance of the pictures made. The illustrations of the facets indirectly show the role of the “human sensor” with respect to the domain of interest. The STEAD approach needs further development of the when-facet and of the relations between the four facets. Finally the results of the approach may support data archives of iLBS applications

The UAE Federal Government’s E-Participation Roadmap: Developments in UAE Empowerment Initiatives With VGI/PGIS and Location Based Services (LBS)

This research assesses the effectiveness of the UAE Federal Government’s e-Participation Policy as used by Cabinet level organizations. Within a vision of Smart City, the UAE E-participation guidelines seem to emulate other public administration approaches to ICT, crowd source information, and interactive communication such as Public Participation Geographic Information System (PPGIS), Volunteer Geographic Information (VGI), and Location Based Services (LBS). It finds that the UAE Federal government uses PGIS in limited ways within a process intending to implement Smart Government, but used in a spontaneous rather than systematic way, thus less efficient in developing increased participation and empowerments. The emphasis on use of LBS linked mobile telephony and online participation tools reflect the government’s forward approach to enhance participation on the road to citizen empowerment

Behaviour of Humans and Behaviour of Models in Dynamic Space

This paper addresses new trends in quantitative geography research. Modern social science research – including economic and social geography – has in the past decades shown an increasing interest in micro-oriented behaviour of actors. This is inter alia clearly reflected in spatial interaction models (SIMs), where discrete choice approaches have assumed a powerful position. This paper aims to provide in particular a concise review of micro-based research, with the aim to review the potential – but also the caveats – of micro-models to map out human behaviour. In particular, attention will be devoted to interactive learning principles that shape individual decisions. Lessons from cognitive sciences will be put forward and illustrated, amongst others on the basis of computational neural networks or spatial econometric approaches. The methodology of deductive reasoning under conditions of large data bases in studying human mobility will be questioned as well. In this context more extensive attention is given to ceteris paribus conditions and evolutionary thinkin

Characterizing New Channels of Communication: A Case Study of Municipal 311 Requests in Edmonton, Canada

City governments around the world are developing and expanding how they connect to citizens. Technologies play an important role in making this connection, and one frequent way that cities connect with citizens is through 311-style request systems. 311 is a non-emergency municipal notification system that uses telephone, email, web forms, and increasingly, mobile applications to allow citizens to notify government of infrastructure issues and make requests for municipal services. In many ways, this process of citizen contribution mirrors the provision of volunteered geographic information, that is spatially-referenced user generated content. This research presents a case study of the city of Edmonton, Canada, an early adopter of multi-channel 311 service request systems, including telephone, email, web form, and mobile app 311 request channels. Three methods of analysis are used to characterize and compare these different channels over three years of request data; a comparison of relative request share for each channel, a spatial hot spot analysis, and regression models to compare channel usage with sociodemographic variables. The results of this study indicate a shift in channel usage from traditional to Internet-enabled, that this shift is mirrored in the hotspots of request activity, and that specific digital inequalities exist that reinforce this distinction between traditional and Internet-enabled reporting channels
