Document Analysis at DFKI Part 2: Information Extraction

40 Pages

Abstract

Document analysis is responsible for an essential progress in office automation. This paper is part of an overview about the combined research efforts in document analysis at DFKI. Common to all document analysis projects is the global goal of providing a high level electronic representation of documents in terms of iconic, structural, textual, and semantic information. These symbolic document descriptions enable an ïntelligent& uml;access to a document database.

Currently there are three ongoing document analysis projects at DFKI: INCA, OMEGA, and PASCAL2000/PASCAL+. Although the projects pursue different goals in different application domains, they all share the same problems which have to be resolved with similar techniques. For that reason the activities in these projects are bundled to avoid redundant work. At DFKI we have divided the problem of document analysis into two main tasks, text recognition and information extraction, which themselves are divided into a set of subtasks.

In a series of three research reports the work of the document analysis and office automation department at DFKI is presented. The first report discusses the problem of text recognition, the second that of information extraction. In a third report we describe our concept for a specialized document analysis knowledge representation language.

The report in hand describes the activities dealing with the information extraction task. Information extraction covers the phases text analysis, message type identification and file integration.
