课程简介:
1. course title: data managementfoundations for location-based services
courseinstructor: christian jensen, professor at aalborg university, denmark
courseabstract:
an increasingly sophisticated infrastructure that encompasses geo-positioningcapabilities and internet-worked mobile computing devices is becoming availableto rapidly growing numbers of users. concurrently, the research community has inventedfoundations that enable location-based services that exploit thisinfrastructure. such services may concern emergency management, transportation,information and social needs, and games, to name but a few possibilities.
these two half-day lectures aim to present an overview of selected datamanagement foundations for location-based services. in this setting, thelocation of a mobile object is captured by a trajectory, which is a functionfrom time to points in the euclidean, spatial-network, or indoor space in whichthe movement occurs.tracking denotes the process of using a positioning systemfor continuously maintaining an up-to-date representation of a (partial) trajectoryof an object. prediction relates to aspects of the future trajectories ofobjects. systems underlying location-based services may be subject to workloadsthat involve frequent updates as well as queries. this calls for efficientupdate as well as query processing techniques, and this in turn calls forefficient indexing techniques. a numberof such techniques have been proposed that are based on the r-tree and the b-tree.these techniques differ in how they contend with skew and other properties ofthe problem domain.
the following topics are planned: 1. motivation; 2. tracking androute prediction; 3. indexing: bottom-up updates, the tpr-tree family, and thebx-tree family; 4. indoor data management techniques: modeling, trajectories,and query processing
2. course title: (1) spatial alarms:architectures and algorithms
(2) privacy challenges in mobilecomputing and location based services
(3)trajectory mining: from subtrajectories, whole trajectories totrajectory patterns
course instructor: ling liu, professor at georgia institute oftechnology, usa
course abstract:
(1) spatial alarms are one of the fundamental capabilities forenabling personalization of location-based services (lbss), especiallylocation-based advertisement, location based entertainment and location basedinformation dissemination. in this lecture, i will describe the alternativearchitectures and algorithms for scaling spatial alarm processing. we willcover three types of system architectural design: client-centric architecture,client-server architecture, and distributed architecture. the algorithms andoptimization techniques for efficient processing of spatial alarms include saferegion techniques for optimizing client energy efficiency, server loads, andnetwork bandwidth efficiency. for example, in a distributed architecture, iwill describe the fundamentals of safe region-based processing and discuss thesuite of techniques for optimal distribution of partial alarm processing tasksfrom the server to the mobile clients while minimizing unnecessary alarmevaluations at both server and mobile clients. i will also describe differentsafe region computation algorithms to explore the impact of size and shape ofthe safe region on network bandwidth, server load and client energyconsumption. the development of these alternative safe region computationtechniques is critical for supporting client device heterogeneity and scalingspatial alarm processing.
(2) we are entering the mobile internet era wherepeople, vehicles, and hand-held devices are connected at all times. locationbecomes a piece of important information for real-time information access,on-demand service discovery and delivery, as well as continuous andpersonalized service provision. in location-based services, there areconceivably two types of location privacy - personal subscriber level privacyand corporate enterprise-level privacy. companies need enterprise-level privacyto preserve corporate secrets and maintain competitive edge. location privacyhas attracted attention in mobile computing, mobile data management, and wirelesscommunication research over the past few years. most of the location privacysolutions try to prevent disclosure of unauthorized location information bytechniques that explicitly or implicitly control what and how locationinformation is given to whom and when. in this lecture, i will give an overviewof location privacy research and discuss three categories of location privacyprotection techniques: (1) location protection through user-defined orsystem-supplied privacy policies; (2) location protection through locationanonymization, a system capability to obfuscate the location information suchthat a state of a subject is not identifiable within the anonymity set; and (3)location protection through pseudonymity of user identities, which uses an internalpseudonym rather than the user’s actual identity. i will also describe theintrinsic relationships among location privacy, location utility, andpersonalization. my lecture will end with a list of open issues and technicalchallenges in location privacy research.
(3) mining mobile object trajectory datasets has been gainingsignificant interest in recent years. we can broadly classify the existingresearch into three categories: mining subtrajectories of mobile objects,mining whole trajectories of mobile objects, and mining trajectory patterns ofmobile objects. density and euclidean distance measures are commonly used bymost of existing approaches to trajectory mining. in this lecture, we show thatwhen the utility of mining mobile objecttrajectories is targeted at road network aware location based applications,density and euclidean distance are no longer the effective measures. this isbecause traffic flows in a road network and the flow-based densitycharacterization become important factors for finding interesting trajectoryclusters of mobile objects travelling on road networks. i will describe one ortwo technical approaches under each of the three categories mentioned above.for example, by taking into account the physical constraints of the roadnetwork, the network proximity and the traffic flows among consecutive roadsegments, the trajectory mining can produe groups of sub-trajectories thatdescribe both dense and highly continuous traffic flows of mobile objects. iwill discuss the technical challenges in mining sparial trajectories.
3. course title: understanding from largescale human behavioral data
course instructor: xing xie博士, msra(微软亚洲研究院)研究员
courseabstract:
with the rapid development of positioning, sensor and smart devicetechnologies, large quantities of human behavioral data are now readilyavailable. they reflect various aspects of human mobility and activities in thephysical world. the availability of this data presents an unprecedentedopportunity to gain a more in depth understanding of users and provide themwith personalized online experience while respecting their privacy. in thiscourse, i will present a number of our recent research efforts on thisdirection, including user mobility understanding and prediction, location andactivity recommendation, user linking across multiple networks, psychologicaltrait inference, life pattern analysis, and driving behavior understanding.
