on measuring the disparity between the desired and actual privacy settings, quantifying the magnitude of the problem of managing privacy. We deploy a survey, implemented as a Facebook application, to 200 Facebook users recruited via Amazon Mechanical Turk. We find that 36 % of content remains shared

Cryptagram: Photo privacy for online social media

by Matt Tierney, Ian Spiro, Christoph Bregler, Lakshminarayanan Subramanian - In Proceeding of the first ACM conference on Online Social Networks (2013), ACM
"... While Online Social Networks (OSNs) enable users to share photos easily, they also expose users to several privacy threats from both the OSNs and external entities. The current pri-vacy controls on OSNs are far from adequate, resulting in inappropriate flows of information when users fail to un-ders ..."

OSNs may further complicate privacy ex-pectations when they reserve the right to analyze uploaded photos using automated face identification techniques. In this paper, we propose the design, implementation and evaluation of Cryptagram, a

Chapter 12 Rough Sets and Rough Logic: A KDD Perspective

by Zdzis Law Pawlak, Lech Polkowski, Andrzej Skowron
"... Abstract Basic ideas of rough set theory were proposed by Zdzis law Pawlak [85, 86] in the early 1980’s. In the ensuing years, we have witnessed a systematic, world–wide growth of interest in rough sets and their applications. The main goal of rough set analysis is induction of approximations of con ..."

Abstract - Add to MetaCart
Organizing conference sessions around themes improves the experience for attendees. However, the session creation process can be difficult and time-consuming due to the amount of expertise and effort required to consider alterna-tive paper groupings. We present a collaborative web appli-cation called Frenzy to draw on the efforts and knowledge of an entire program committee. Frenzy comprises (a) inter-faces to support large numbers of experts working collec-tively to create sessions, and (b) a two-stage process that decomposes the session-creation problem into meta-data elicitation and global constraint satisfaction. Meta-data elicitation involves a large group of experts working simul-taneously, while global constraint satisfaction involves a smaller group that uses the meta-data to form sessions. We evaluated Frenzy with 48 people during a deployment at the CSCW 2014 program committee meeting. The ses-sion making process was much faster than the traditional process, taking 88 minutes instead of a full day. We found that meta-data elicitation was useful for session creation. Moreover, the sessions created by Frenzy were the basis of the CSCW 2014 schedule. Author Keywords Crowdsourcing; groupware; communitysourcing
