DeepPeep is a search engine specialized in Web forms. The current beta version tracks 45,000 forms across 7 domains.

DeepPeep helps you discover the entry points to content in Deep Web (aka Hidden Web) sites, including online databases and Web services.

This search engine is designed to cater to the needs of casual Web users in search of online databases (e.g., to search for forms related to used cars), as well as expert users whose goal is to build applications that access hidden-Web information (e.g., to obtain forms in job domain that contain salary, or discover common attribute names in a domain).

The development of DeepPeep has been funded by National Science Foundation award #0713637 III-COR: Discovering and Organizing Hidden-Web Sources
