2009 Proceedings of the 12th International Conference on Extending Database Technology Advances in Database Technology - EDBT '09  
In this demo, we show data clouds that summarize the results of keyword searches over structured data.  ...  In this demo paper: • we summarize the main issues for generating data clouds • we give an overview of our framework for keyword searching with summaries (clouds) • we describe our system CourseCloud that  ...  Furthermore, we couple the flexibility of keyword searches over structured data with the summarization and visualization capabilities of tag clouds to help users search a database.  ...

Data clouds

Georgia Koutrika, Zahra Mohammadi Zadeh, Hector Garcia-Molina
2009 Proceedings of the 12th International Conference on Extending Database Technology Advances in Database Technology - EDBT '09  
We propose using clouds over structured data (data clouds) to summarize the results of keyword searches over structured data and to guide users to refine their searches.  ...  In this paper, we propose coupling the flexibility of keyword searches over structured data with the summarization and navigation capabilities of tag clouds to help users access a database.  ...  CourseCloud generates a data cloud to summarize the results of a keyword search over structured data.  ...

2009 Proceedings of the 35th SIGMOD international conference on Management of data - SIGMOD '09  
The purpose of this demo is to show the challenges, special features and potential of a focused social system in action through CourseRank, a course evaluation and planning social system.  ...  We transfer the idea of tag clouds over structured data and use them to summarize search results over a database.  ...  A given recommendation approach can be expressed declaratively as a high-level workflow over structured data and then executed by the underlying engine.  ...

Social Systems: Can we Do More Than Just Poke Friends? [article]

Georgia Koutrika, Benjamin Bercovitz (Stanford University), Robert Ikeda, Filip Kaliszan (Stanford University), Henry Liou, Zahra Mohammadi Zadeh
2009 arXiv   pre-print
Are they good only for simple tasks, such as tagging and poking friends? Do they present any new or interesting research challenges?  ...  In this paper, we describe the insights we have obtained implementing CourseRank, a course evaluation and planning social system.  ...  Hence, we couple the flexibility of keyword searches over structured data with the summarization and visualization capabilities of tag clouds to help users search a database.  ...
