We describe a biographical multi-document summarizer that summarizes information about people described in the news. The summarizer uses corpus statistics along with linguistic knowledge to select and merge descriptions of people from a document collection, removing redundant descriptions. The summarization components have been extensively evaluated for(More)
We describe a system called AutoBriefer which automatically generates multimedia briefings from high-level outlines. The author of the briefing interacts with the system to specify some of the briefing content. In order to be scalable across domains, AutoBriefer provides a graphical user interface (GUI) that allows the user to create or edit domain(More)
The emergence of vast quantities of on-line information has raised the importance of methods for automatic cataloguing of information in a variety of domains, including electronic commerce and bioinformatics. Ontologies can play a critical role in such cataloguing. In this paper, we describe a system that automatically induces an ontology from any large(More)
OBJECTIVE The authors present a system that scans electronic records from cardiac surgery and uses inference rules to identify and classify abnormal events (e.g., hypertension) that may occur during critical surgical points (e.g., start of bypass). This vital information is used as the content of automatically generated briefings designed by MAGIC, a(More)
Document production is an important function in many organizations. In addition to instruction manuals, courseware, reports, system documentation, etc., briefings are a very common type of document product, often used in slide form as a visual accompaniment to a talk. This paper describes a domain-independent system for automatic briefing generation from a(More)
As part of MITRE's work under the DARPA TIDES (Translingual Information Detection, Extraction and Summarization) program, we are preparing a series of demonstrations to showcase the TIDES Integrated Feasibility Experiment on Bio-Security (IFE-Bio). The current demonstration illustrates some of the resources that can be made available to analysts tasked with(More)
