Description
Summary:The Web contains an abundance of useful semi-structured information that can and should be mined. Types of structure include hyperlinks between pages, structure within hypertext pages, and structure within URLs. We have implemented a programming language, Squeal, that facilitates structure-based queries. Specifically, the Squeal user can query the Web as if it were in a standard relational database. We describe Squeal and show the ease of writing structure-based information tools in Squeal.
