- KonferenzbeitragModelling missing values for audience measurement in outdoor advertising using GPS data(Informatik 2009 – Im Focus das Leben, 2009) May, Michael; Körner, Christine; Hecker, Dirk; Pasquier, Martial; Hofmann, Urs; Mende, FelixGPS technology has made it possible to evaluate the performance of outdoor advertising campaigns in an objective manner. Given the GPS trajectories of a sample of test persons over several days, their passages with arbitrary poster campaigns can be calculated. However, inference is complicated by the early dropout of persons. Other than in most demonstrations of spatial data mining algorithms where the structure of the data sample is usually disregarded, poster performance measures such as reach and gross impressions evolve continuously over time and require nonintermittent observations. In this paper, we investigate the applicability of survival analysis to compensate for missing measurement days. We formalize the task of modeling the visit potential of geographic locations based on trajectory data as our variable of interest results from dispersed events in space-time. We perform experiments on the cities of Zurich and Bern simulating different dropout mechanisms and dropout rates and show the adequacy of the applied method. Our modeling technique is at present part of a business solution for the Swiss outdoor advertising branch and serves as pricing basis for the majority of Swiss poster locations.

- KonferenzbeitragPervasive advertising(Informatik 2009 – Im Focus das Leben, 2009) Müller , Jörg; Holleis, Paul; Schmidt, Albrecht; May, MichaelPervasive Advertising (pervasiveadvertising.org) explores the application of pervasive computing technologies to the domain of advertising. Over the last decade many pervasive computing technologies have emerged, most notably mobile devices, ubiquitous digital displays, and a variety of location system and tracking tools. As these technologies become widespread new opportunities and challenges for advertising arise. In this second workshop on pervasive advertising we hope to get a wider overview of current research efforts and application opportunities as well as a chance to map out a roadmap for further research and deployment challenges in this domain.
- ZeitschriftenartikelSpatiotemporal Modeling and Analysis—Introduction and Overview(KI - Künstliche Intelligenz: Vol. 26, No. 3, 2012) Körner, Christine; May, Michael; Wrobel, StefanOver the past five to seven years the analysis of trajectory data has established itself as an independent research discipline within the area of data mining. In this article we provide an overview on data characteristics, state-of-the-art preprocessing and analysis methods of trajectory data. We conclude the article with a collection of challenges that arise due to the increasing variety of spatiotemporal data sources and which have to be solved for the application of spatiotemporal analysis methods in practice.
