As a tool for mitigating the potential privacy risks of gathering and transmitting location information on the Web, we suggest in this paper a model for conveying location information together with privacy rules to govern the use of that information. Binding privacy rules to the conveyance of location information is one useful tool to help developers build location-based systems and services that comport with the concept of fair information practices (FIPs)---a set of widely accepted principles that create a basis for privacy-protective systems. We offer as a model one fully developed set of standards for binding location data conveyed across IP networks to privacy rules.

In this paper we present the connected traveler architecture that allows mobile users to personalize the delivery of transportation related content. The widespread use of mobile devices and the increasing availability of wireless internet present an opportunity for transportation engineers to deliver mobility and safety content to the drivers, pedestrians and public transit users. Connectedtraveler.org enables this technology by combining the location of the mobile user with pre-defined personalized profiles to improve user experience.

In this position paper the question of how location is employed in location based services (LBS) is considered. The importance of the notion of location is highlighted as a means of blurring the boundary between forms of experiences that are direct, and sensed in the environment, and those that are indirect, and learned from information. It is suggested that current methods for modeling location are limited by their lack of strong theoretical underpinning. To help bridge this gap the notions of Space, Place, and Region, from geographical theory, are proposed and implications of these for considering location in LBS outlined.

In this position paper we describe the concept of geographic relevance and its potential for mobile location-based services employing the mobile Internet. We argue that existing LBS have a too limited concept of location and its application for filtering geographic content. We propose an approach for geographic relevance that extends LBS and location-aware web applications and aims at better supporting mobile users' decision-making based on geographic information. After a short description of an ongoing project we discuss the different roles of location and the different conceptions of space that can be involved in assessing and representing geographic relevance. Finally we provide a few concluding statements that aim at stimulating a cross-disciplinary discussion about location and its importance for relevance.

We propose a novel method to detect cultural differences over the world automatically by using a large amount of geotagged images on the photo sharing Web sites such as Flickr. We employ the state-of-the-art object recognition technique developed in the research community of computer vision to mine representative photos of the given concept for representative local regions from a large-scale unorganized collection of consumer-generated geotagged photos. The results help us understand how objects, scenes or events corresponding to the same given concept are visually different depending on local regions over the world.

Microsoft has proposed an identity metasystem to standardize identity services and the principles behind them. A location metasystem can support interoperation between location services, protect users' privacy and handle issues of granularity. The simple OAuth protocol may be a good model for working towards a location metasystem.

Location-Based Services are becoming increasingly Web-based, as a result of the availability of networked mobile devices and mobile Internet access. The "Location and the Web (LocWeb)" workshop targets the capabilities and constraints of Web-based location-based services, which can be implemented as browser-based applications, or as native applications using Web services. The focus of this CHI workshop is on developing approaches to handle the complexity of location-based services, specifically looking at location abstractions, location sharing, context-relevant information, privacy issues, and interface design. The goal of this workshop is to serve as a starting point for better understanding how the Web has to change to embrace location as a first-level concept, and how these changes are reflected in applications and user interfaces to transform the Web into a platform for location-based services.

We propose that the concepts of Time Geography be evaluated as a framework for use within location-oriented services. Originally conceived as a system to describe patterns in human migration, Time Geography is ideally suited for providing the common language and concepts necessary for dialogue within this evolving area. Location-oriented services have been the focus of a great deal of attention, but with research occurring in many disparate disciplines, the lack of a common model that can conceptualize these ideas has not received appropriate attention. To demonstrate its applicability within location-oriented services, we present a research activity which makes explicit use of concepts from Time Geography, with the hope that it can be seen as a tractable and practical solution for several difficulties facing this fast growing area of interest.

We present a computational framework to automatically discover high-order temporal social patterns from very noisy and sparse location data. We introduce the concept of social footprint and present a method to construct a codebook, enabling the transformation of raw sensor data into a collection of social pages. Each page captures social activities of a user over regular time period, and represented as a sequence of encoded footprints. Computable patterns are then defined as repeated structures found in these sequences. To do so, we appeal to modeling tools in document analysis and propose a Latent Social theme Dirichlet Allocation (LSDA) model -- a version of the Ngram topic model in [6] with extra modeling of personal context. This model can be viewed as a Bayesian clustering method, jointly discovering temporal collocation of footprints and exploiting statistical strength across social pages, to automatically discovery high-order patterns. Alternatively, it can be viewed as a dimensionality reduction method where the reduced latent space can be interpreted as the hidden social 'theme' -- a more abstract perception of user's daily activities. Applying this framework to a real-world noisy dataset collected over 1.5 years, we show that many useful and interesting patterns can be computed. Interpretable social themes can also be deduced from the discovered patterns.
