LFCS seminar: Andrea Cali: Searching and querying the deep web: a foundational approach

ABSTRACT:
The Deep Web is constituted by data that are accessible on the web, typically through HTML forms, but are not indexable by search engines due to their static nature. Processing queries on Deep Web data poses significant challenges as data sources cannot be normally accessed with arbitrary queries. In this talk we illustrate techniques for processing structured as well as keyword queries on the Deep Web and we survey some of the core problems underlying the query processing task.
