摘要

Jedi(基于Java的信息提取和传播)是一种轻量级工具，用于创建包装器和中介器，以从几个独立的信息源中提取、组合和协调信息。对于包装器，它使用带有属性的语法，这些语法使用容错解析策略进行评估，以处理模糊语法和不规则源。对于中介，它使用一个简单的通用对象模型，该模型可以使用针对特定模型(如HTML、XML或关系模型)的java库进行扩展。本文介绍了Jedi的体系结构，然后重点介绍了Jedi的包装器生成器。

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.
