Jedi: extracting and synthesizing information from the Web
Jedi (Java based Extraction and Dissemination of Information) is a lightweight tool for the creation of wrappers and mediators to extract, combine, and reconcile information from several independent information sources. For wrappers it uses attributed grammars, which are evaluated with a fault-tolerant parsing strategy to cope with ambiguous grammars and irregular sources. For mediation it uses a simple generic object-model that can be extended with Java-libraries for specific models such as HTML, XML or the relational model. This paper describes the architecture of Jedi, and then focuses on Jedi's wrapper generator.
