Modelspace - Cooperative Document Information Extraction in Flexible Hierarchies

Abstract

Business document indexing for ordered filing of documents is a crucial task for every company. Since this is a tedious error prone work, automatic or at least semi-automatic approaches have a high value. One approach for semi-automated indexing of business documents uses self-learning information extraction methods based on user feedback. While these methods require no management of complex indexing rules, learning by user feedback requires each user to first provide a number of correct extractions before getting appropriate automatic results. To eliminate this cold start problem we propose a cooperative approach to document information extraction involving dynamic hierarchies of extraction services. We provide strategies for making the decision when to contact another information extraction service within the hierarchy, methods to combine results from different sources, as well as aging and split strategies to reduce the size of cooperatively used indexes. An evaluation with a large number of real-world business documents shows the benefits of our approach.
