Exploration of Deep Web Repositories

With the proliferation of online repositories (e.g., databases or document corpora) hidden behind proprietary web interfaces, e.g., keyword-/form-based search and hierarchical/graph-based browsing interfaces, efficient ways of exploring contents in such hidden repositories are of increasing importance. There are two key challenges: one on the proper understanding of interfaces, and the other on the efficient exploration, e.g., crawling, sampling and analytical processing, of very large repositories. In this paper, the authors focus on the fundamental developments in the field, including web interface understanding, crawling, sampling, and data analytics over web repositories with various types of interfaces and containing structured or unstructured data. Their goal is to encourage audience to initiate their own research in these exciting areas.
