Generating Domain Terminologies using Root- and Rule-Based Terms

December 21, 2018
Author(s)
Talapady N. Bhat, John T. Elliott, Ursula R. Kattner, Carelyn E. Campbell, Eswaran Subrahmanian, Ram D. Sriram, Jacob Collard, Monarch Ira
Motivated by the need for exible, intuitive, reusable, and normalized ter- minology for the semantic web, we present a general approach for generat- ing sets of such terminologies from nat- ural language documents. The terms that this approach generates

Author(s)
Jeffrey M. Shainline, Adam N. McCaughan, Jeffrey T. Chiles, Richard P. Mirin, Sae Woo Nam, Sonia M. Buckley
We present designs of superconducting optoelectronic neurons based on superconducting single- photon detectors, Josephson junctions, semiconductor light sources, and multi-planar dielectric waveguides. The neurons send few-photon signals to synaptic

Blockchain Technology Overview

October 3, 2018
Author(s)
Dylan J. Yaga, Peter M. Mell, Nik Roby, Karen Scarfone
Blockchains are tamper evident and tamper resistant digital ledgers implemented in a distributed fashion (i.e., without a central repository) and usually without a central authority (i.e., a bank, company, or government). At their basic level, they enable

2017 NIST/ITL Cybersecurity Program: Annual Report

Yee-Yin Choong, Shanee T. Dawkins, Susanne M. Furman, Kristen Greene, Sandra S. Prettyman, Mary F. Theofanos
The public safety community is in the process of transitioning from the use of land mobile radios to a technology ecosystem including a variety of broadband data sharing platforms. Successful deployment and adoption of new communication technology relies

User Context: An Explanatory Variable in Phishing Susceptibility

July 15, 2018
Author(s)
Kristen K. Greene, Michelle P. Steves, Mary Theofanos, Jennifer A. Kostick
Extensive research has been performed to examine the effectiveness of phishing defenses, but much of this research was performed in laboratory settings. In contrast, this work presents 4.5 years of workplace-situated, embedded phishing email training

In IoT We Trust?

July 13, 2018
Author(s)
Jeff Voas, D. Richard Kuhn, Phillip Laplante
In this short article, we review an abbreviated list of trust challenges that we foresee as increased adoption transforms the IoT into another ubiquitous technology just as the Internet is. These challenges are in no specific order, and are by no means a

Towards Managing Age of Network State Information in Challenged Networks

July 8, 2018
