Purple SOX Extraction Management System

摘要

We describe the Purple SOX (PSOX) EMS, a prototype Extraction Management System currently being built at Yahoo!. The goal of the PSOX EMS is to manage a large number of sophisticated extraction pipelines across different application domains, at the web scale and with minimum human involvement. Three key value propositions are described: extensibility, the ability to swap in and out extraction operators; explainability, the ability to track the provenance of extraction results; and social feedback support, the facility for gathering and reconciling multiple, potentially conflicting sources.
