Wrapper Induction and Maintenance in Documentum ECI
Boris Chidlovskii, Bruno Roustant, Marc Brette · 2006
Documentum Enterprise Content Integration (ECI) services is a content integration middleware that provides one-query access to the Intranet and Internet content resources. The ECI Adapter tech-nology offers an interface to any application for data and metadata extraction from unstructured Web pages. It offers a unique frame-work of wrapper production, automatic recovery and maintenance, developed at Xerox Research Centre Europe and based on state-of-art algorithms from machine learning and grammatical inference. In this paper we analyze the performance of ECI adapters deployed in current commercial installations. We benefit from accessing re-ports on daily tests for all ECI commercially deployed adapters col-lected from June 2003 to December 2005. Using the daily reports, we analyze different aspects of the wrapper technology.
