In recent years, data exploration and analytics problems have been encountered in novel application domains, such as in collaborative/social media and deep web databases. This talk will summarize some of our recent research efforts in these areas. For collaborative and social media, we have developed a framework for exploratory mining of user interaction on web content, which can be leveraged in a variety of applications such as socially-aware recommendation systems, snippet advertising, and new item design. For deep web databases, we will consider the problems of crawling, sampling, and data analytics over such web sources, which is challenging because deep web databases are often locked behind proprietary search interfaces. Our talk will focus on describing the interesting technical challenges and algorithmic innovations necessary to address these emerging problems.
