ABSTRACT
Many people use the Internet to search for geographically local information, with a growing number of websites dedicated to this task. However, it is not clear exactly how users integrate geographic search with content-based search, nor how to obtain reliable information about places in a geographic region. We created Sharescape, a map-based application in which information is contributed by community members. We conducted a user study to evaluate the utility of this means of obtaining information and to investigate how users integrate geographic and content-based search. Our results suggest that 1) maps create an implicit context in an interface that designers should honor, 2) community-maintained information about local geography has important benefits over information mined from web sites, and 3) users often are not aware of the privacy implications of their actions, and therefore designers should incorporate special privacy safeguards.

A Pen-Based Prosodic User Interface for Schoolchildren
A prosodic user interface is defined as an user interface that can deal with not only what is entered by the user but also how it is entered. A pen-based user interface provides more prosodic information than a mouse-based graphical user interface. The ...
Community-based ranking of the social web
HT '10: Proceedings of the 21st ACM conference on Hypertext and hypermediaThe rise of social interactions on the Web requires developing new methods of information organization and discovery. To that end, we propose a generative community-based probabilistic tagging model that can automatically uncover communities of users ...
