Abstract

A data extraction model, named the browser-oriented data extraction (BODE) model, was proposed by I-Chen Wu et al. (2005) to extract Web contents with script functions. In this model, the system built on top of browsers accesses pages by simulating users´ operations on browsers. Based on this model, this paper defines a scripting language, named the BODED (browser-oriented data extraction description) language, which instructs the system how to do data extraction. This paper proposes a technique, called indirect browser replication to implement a BODE system, and also optimize the performance of this technique.
