Many popular online services provide "local" or "yellow-pages" search, but none of them allow users to customize the search over user-specified data. Instead, searches are performed over spatial data provided by data aggregators. This paper describes a novel system for providing custom local search over user-provided custom spatial datasets logically combined with detailed streetlevel vector data. We present the algorithms and architecture underlying our prototype system, which can handle a

We show that the system provides custom local search with precision and recall figures that often exceed that of a commercial local search service. Further, we show that our system scales gracefully with the number of individual custom data sets being served simultaneously.

2010 Proceedings of the international conference on Multimedia - MM '10  
The cultural heritage of a region is conveyed by both tangible physical artifacts and intangible aspects in the form of stories, dance styles, rituals, etc. Hitherto, the task of creating digital representations for each of these aspects has been addressed in isolation, i.e. using specific media most suited to the artifact such as video, audio, three-dimensional (3D) models, scanning, etc. The challenge of bringing together these separate elements to create a coherent story, however, has

Our approach results in a compelling and engaging narration that affords a unified user experience. Our solution supports both active (user-controlled explorations) and passive (watching pre-orchestrated narrations) user interactions. We demonstrate the capabilities of our framework through a qualitative user study based on two rich interactive narratives built using our framework: (1) history and folklore surrounding a temple in South India, and (2) a historical account of an educational institution also in South India.

Due to the recent emergence of massive open online courses (MOOCs), students and teachers are gaining unprecedented access to high-quality educational content. However, many questions remain on how best to utilize that content in a classroom environment. In this small-scale, exploratory study, we compared two ways of using a recorded video lecture. In the online learning condition, students viewed the video on a personal computer, and also viewed a follow-up tutorial (a quiz review) on the

We randomly assigned 102 students to these conditions, and assessed learning outcomes via a series of quizzes. While we saw significant learning gains after each session conducted, we did not observe any significant differences between the online and blended learning groups. We discuss these findings as well as areas for future work.

In this demo, we present a wiki-style platform -WikiBABELthat enables easy collaborative creation of multilingual content in many non-English Wikipedias, by leveraging the relatively larger and more stable content in the English Wikipedia. The platform provides an intuitive user interface that maintains the user focus on the multilingual Wikipedia content creation, by engaging search tools for easy discoverability of related English source material, and a set of linguistic and collaborative

Such integrated content creation platform in Wikipedia may yield as a by-product, parallel corpora that are critical for research in statistical machine translation systems in many languages of the world.
