Techniques and Rule Patterns for Declaratively Querying Web Data with FLORID

Bertram Ludäscher, Rainer Himmeröder, Wolfgang May


FLORID is an implementation of the deductive object-oriented database language F-logic and has recently been extended to provide a declarative semantics for querying the Web. By means of several illustrative examples, we show how \florid's rule-based logical language can be used to extract, query, and analyze data from the Web.
