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 technology offers an interface to any application for data and metadata extraction from unstructured Web pages. It offers a unique framework of wrapper production, automatic recovery and maintenance, developed at Xerox Research Center Europe and based on state-of-art algorithms from machine learning and grammatical inference. In this presentation we analyze the performance of ECI adapters deployed in current commercial installations. We benefit from accessing reports on daily tests for all ECI commercially deployed adapters collected from June 2003 to September 2005. Using the daily reports, we analyze different aspects of the wrapper technology
