Article No.: 31
DOI: 10.1145/2700466

There has been much effort on studying how social media sites, such as Twitter, help propagate information in different situations, including spreading alerts and SOS messages in an emergency. However, existing work has not addressed how to...

Simplifying Data Disclosure Configurations in a Cloud Computing Environment
Ron Hirschprung, Eran Toch, Oded Maimon
Article No.: 32
DOI: 10.1145/2700472

Cloud computing offers a compelling vision of computation, enabling an unprecedented level of data distribution and sharing. Beyond improving the computing infrastructure, cloud computing enables a higher level of interoperability between...

User-Specific Feature-Based Similarity Models for Top-n Recommendation of New Items
Asmaa Elbadrawy, George Karypis
Article No.: 33
DOI: 10.1145/2700495

Recommending new items for suitable users is an important yet challenging problem due to the lack of preference history for the new items. Noncollaborative user modeling techniques that rely on the item features can be used to recommend new items....
