Efficient, intelligent systems for navigating the biological literature. Final report, September 15, 1993--September 14, 1996
The biological literature is huge and increasingly moving to electronic form. By developing a variety of new techniques, it should be possible to take advantage of this huge and growing electronic store. Computers should allow one to use the literature with greater efficiency and insight to disseminate information and to advance scientific understanding. Though there is a great deal of research and development effort focused on electronic text, e.g., the Digital Libraries initiative, little attention has been paid to the diagrammatic content of documents. However, it is common knowledge among biologists, and scientists in general, that the figures in documents are of critical importance. Little work has been done to develop principles and systems for analyzing, representing, and indexing and searching the diagrammatic content of electronic documents. This has been the main thrust of this research project. The primary work in the world on the analysis of graphics in documents has been focused on low-level issues relating to scanning legacy documents (hardcopy) and trying to discover the graphics elements in them. Graphics files, as opposed to image files, have lines, curves, polygons, text, etc., represented as discrete objects, as they are originally generated in drawing and graphing applications. This has …

Issues in Benchmarking Human Reliability Analysis Methods: A Literature Review.
There is a diversity of human reliability analysis (HRA) methods available for use in assessing human performance within probabilistic risk assessment (PRA). Due to the significant differences in the methods, including the scope, approach, and underlying models, there is a need for an empirical comparison investigating the validity and reliability of the methods. To accomplish this empirical comparison, a benchmarking study is currently underway that compares HRA methods with each other and against operator performance in simulator studies. In order to account for as many effects as possible in the construction of this benchmarking study, a literature review was conducted, reviewing past benchmarking studies in the areas of psychology and risk assessment. A number of lessons learned through these studies are presented in order to aid in the design of future HRA benchmarking endeavors.

VISTA (Vertical Integration of Science, Technology, and Applications) user interface software study
The Vertical Integration of Science, Technology, and Applications (VISTA) project is an initiative to employ modern information and communications technology for rapid and effective application of basic research results by end users. Developed by the Pacific Northwest Laboratory, VISTA's purpose is to develop and deploy information systems (software or software/hardware products) to broad segments of various markets. Inherent in these products would be mechanisms for accessing PNL-resident information about the problem. A goal of VISTA is to incorporate existing, commercially available user interface technology into the VISTA UIMS. Commercial systems are generally more complete, reliable, and cost-effective than software developed in-house. The objective of this report is to examine the current state of commercial user interface software and discuss the implications of selections thereof. This report begins by describing the functionality of the user interface as it applies to users and application developers. Next, a reference model is presented defining the various operational software layers of a graphical user interface. The main body follows which examines current user interface technology by sampling a number of commercial systems. Both the window system and user interface toolkit markets are surveyed.

Data Mining for Security Information: A Survey
This paper will present a survey of the current published work and products available to do off-line data mining for computer network security information. Hundreds of megabytes of data are collected every second that are of interest to computer security professionals. This data can answer questions ranging from the proactive, ''Which machines are the attackers going to try to compromise?'' to the reactive, ''When did the intruder break into my system and how?'' Unfortunately, there's so much data that computer security professionals don't have time to sort through it all. What we need are systems that perform data mining at various levels on this corpus of data in order to ease the burden of the human analyst. Such systems typically operate on log data produced by hosts, firewalls and intrusion detection systems as such data is typically in a standard, machine readable format and usually provides information that is most relevant to the security of the system. Systems that do this type of data mining for security information fall under the classification of intrusion detection systems. It is important to point out that we are not surveying real-time intrusion detection systems. Instead, we examined what is possible when the analysis …

Security classification of information
This document is the second of a planned four-volume work that comprehensively discusses the security classification of information. The main focus of Volume 2 is on the principles for classification of information. Included herein are descriptions of the two major types of information that governments classify for national security reasons (subjective and objective information), guidance to use when determining whether information under consideration for classification is controlled by the government (a necessary requirement for classification to be effective), information disclosure risks and benefits (the benefits and costs of classification), standards to use when balancing information disclosure risks and benefits, guidance for assigning classification levels (Top Secret, Secret, or Confidential) to classified information, guidance for determining how long information should be classified (classification duration), classification of associations of information, classification of compilations of information, and principles for declassifying and downgrading information. Rules or principles of certain areas of our legal system (e.g., trade secret law) are sometimes mentioned to .provide added support to some of those classification principles.

Information Extraction from Unstructured Text for the Biodefense Knowledge Center
The Bio-Encyclopedia at the Biodefense Knowledge Center (BKC) is being constructed to allow an early detection of emerging biological threats to homeland security. It requires highly structured information extracted from variety of data sources. However, the quantity of new and vital information available from every day sources cannot be assimilated by hand, and therefore reliable high-throughput information extraction techniques are much anticipated. In support of the BKC, Lawrence Livermore National Laboratory and Oak Ridge National Laboratory, together with the University of Utah, are developing an information extraction system built around the bioterrorism domain. This paper reports two important pieces of our effort integrated in the system: key phrase extraction and semantic tagging. Whereas two key phrase extraction technologies developed during the course of project help identify relevant texts, our state-of-the-art semantic tagging system can pinpoint phrases related to emerging biological threats. Also we are enhancing and tailoring the Bio-Encyclopedia by augmenting semantic dictionaries and extracting details of important events, such as suspected disease outbreaks. Some of these technologies have already been applied to large corpora of free text sources vital to the BKC mission, including ProMED-mail, PubMed abstracts, and the DHS's Information Analysis and Infrastructure Protection (IAIP) news clippings.

Energy conservation by hyperfiltration: food industry background literature survey
The application of hyperfiltration to selected food product streams and food processing wastewaters for energy conservation was examined. This literature survey had led to the following conclusions: no research has been conducted in the food industry using membranes with hot process streams due to the temperature limitation (< 40/sup 0/C) of the typically studied cellulose acetate membranes; based on the bench-scale research reviewed, concentration of fruit and vegetable juices with membranes appears to be technically feasible; pretreatment and product recovery research was conducted with membranes on citrus peel oil, potato processing and brine wastewaters and wheys. The experiments demonstrated that these applications are feasible; many of the problems that have been identified with membranes are associated with either the suspended solids or the high osmotic pressure and viscosity of many foods; research using dynamic membranes has been conducted with various effluents, at temperatures to approx. 100/sup 0/C, at pressures to 1200 psi and with suspended solids to approx. 2%; and, the dynamic membrane is being prototype tested by NASA for high temperature processing of shower water. The literature review substantiates potential for dynamic membrane on porous stainless tubes to process a number of hot process and effluent streams in the …

Record Linkage and Privacy: Issues in Creating New Federal Research and Statistical Information
Other written product issued by the General Accounting Office with an abstract that begins "This study focuses on privacy issues related to record-linkage--a computer-based process that combines multiple sources of existing data. Federally sponsored linkage projects conducted for research and statistical purposes have many potential benefits, such as informing policy debates; tracking program outcomes; helping local government or business planning; or contributing knowledge that, in some cases, might help millions of people. Despite these benefits, concerns about personal privacy are relevant because linkages often involve data on identifiable persons. GAO describes (1) how record linkage can create new research and statistical information, (2) why linkage heightens certain privacy issues, and (3) how data stewardship might be enhanced."
