Abstract

A wealth of structured, publicly-available information exists in the deep web but is only accessible by querying web forms. As a result, users are restricted by the interfaces provided and lack a convenient mechanism to express novel and independent extractions and queries on the underlying data. Transcendence enables personalized access to the deep web by enabling users to partially reconstruct web databases in order to perform new types of queries. From just a few examples, Transcendence helps users produce a large number of values for form input fields by using unsupervised information extraction and collaborative filtering of user suggestions. Structural and semantic analysis of returned pages finds individual results and identifies relevant fields. Users may revise automated decisions, balancing the power of automation with the errors it can introduce. In a user evaluation, both programmers and non-programmers found Transcendence to be a powerful way to explore deep web resources and wanted to use it in the future.
