Using Replicates in Information Retrieval Evaluation

August 2, 2017
Author(s)
Ellen M. Voorhees, Daniel V. Samarov, Ian M. Soboroff
This paper explores a method for more accurately estimating the main effect of the system in a typical test-collection-based evaluation of information retrieval systems, and thus increasing the sensitivity of system comparisons. Randomly partitioning the

Event Nugget and Event Coreference Annotation

June 17, 2017
Author(s)
Zhiyi Song, Ann Bies, Stephanie Strassel, Teruko Mitamura, Hoa T. Dang, Joe Ellis, Sue Holm, Yakari Yamakawa
In this paper, we describe the event nugget annotation created in support of the pilot Event Nugget Detection evaluation in 2014 and in support of the Event Nugget Detection and TAC KBP open evaluation in 2015. We present the data volume for both training

Towards a Platform for Community-centric Smart Connected Services

Instance Search Retrospective with Focus on TRECVID

April 5, 2017
Author(s)
George M. Awad, Wessel Kraaij, Paul Over, Shin'ichi Satoh
This paper presents an overview of the Video Instance Search benchmark which was run over a pe- riod of 6 years (2010-2015) as part of the TREC Video Retrieval (TRECVID) workshop series. The main contributions of the paper include i) an examination of the

TRECVID 2016 Video to Text Description NEW Showcase/Pilot Task Overview

April 5, 2017
Author(s)
George M. Awad
A new pilot task was introduced and evaluated during the TRECIVD 2016 workshop cycle. The task evaluates methods that provides solutions to describe short videos into natural text descriptions and also methods that matches short videos to short english

GAUSSIAN PROCESS REGRESSION (GPR) REPRESENTATION IN PREDICTIVE MODEL MARKUP LANGUAGE (PMML)

March 29, 2017
Author(s)
Jinkyoo Park, David Lechevalier, Ronay Ak, Max K. Ferguson, Kincho H. Law, Yung-Tsun Lee, Sudarsan Rachuri
This paper describes a Predictive Model Markup Language (PMML) representation of Gaussian Process Regression (GPR) models. PMML is an XML-based standard language used to represent data mining and predictive analytic models, as well as pre- and post

Superconducting Optoelectronic Circuits for Neuromorphic Computing

March 23, 2017
Author(s)
Jeffrey M. Shainline, Sonia M. Buckley, Richard P. Mirin, Sae Woo Nam
We propose a hybrid semiconductor-superconductor hardware platform for the implementation of neural networks and large-scale neuromorphic computing. The platform combines semiconducting few-photon light-emitting diodes with superconducting-nanowire single

Synchrophasor Data Quality Attributes and a Methodology for Examining Data Quality Impacts upon Synchrophasor Applications

March 14, 2017
Author(s)
Dhananjay Anand, Allen R. Goldstein, Alison Silverstein, Laurie Miller, Francis Tuffner, Yuri Makarov
Data from synchrophasor devices like phasor measurement units (PMU) is increasingly being used to enhance and improve power grid operations, analysis, and planning applications. However, PMU data often arrive at the application with a variety of data

Expanding lipidome coverage using LC-MS/MS data-dependent acquisition with automated exclusion list generation

March 6, 2017
Author(s)
John Bowden, Jeremy P. Koelmel, Nicholas M. Kroeger, Emily L. Gill, Candice Z. Ulmer, Rainey E. Patterson, Richard A. Yost, Timothy J. Garrett
Untargeted omics analyses aim to comprehensively characterize biomolecules within a biological system. Changes in the presence or quantity of these biomolecules can indicate important biological perturbations, such as those caused by disease. With current

Classification of petroleum Standard Reference Materials and other fuels by chemometric analysis of gas chromatography-mass spectrometry data

February 23, 2017
Author(s)
Werickson Fortunato de Carvalho Rocha, Michele M. Schantz, David Sheen, Katrice Lippa, Pamela M. Chu
As feedstocks transition from conventional oil to increasing amounts of unconventional petroleum sources and biomass, it will be necessary to determine whether a particular fuel or fuel blend is suitable for use in engines. Certifying a fuel as safe for

The Impact of Data Dependency on Speaker Recognition Evaluation

February 8, 2017
Author(s)
Jin Chu Wu, Alvin F. Martin, Craig S. Greenberg, Raghu N. Kacker
The data dependency due to multiple use of the same subjects has impact on the standard error (SE) of the detection cost function (DCF) in speaker recognition evaluation. The DCF is defined as a weighted sum of the probabilities of type I and type II

A Category Theoretic Approach to Modeling and Analysis Using Music as a Case Study

January 31, 2017
Author(s)
Sarala Padi, Spencer J. Breiner, Eswaran Subrahmanian, Ram D. Sriram
The goal of this paper is to provide a category theoretic ontology for the creation of a collaborative platform where it allows group of people to share or use the knowledge in a domain. We use Indian music as a case study to demonstrate the power of

2015 Location-Based Services R&D Summit Report

Harris Feldman, Adam H. Danielson
The Public Safety Communications Research Program (PSCR) convened over 80 stakeholders at the National Institute of Standards and Technology (NIST) Boulder, CO campus to build on the findings presented in the 2015 Location-Based Services (LBS) Summit- held

Beyond IRBs: Designing Ethical Review Processes for Big Data Research

January 25, 2017
Author(s)
Simson L. Garfinkel
Big Data Research is something new, a practice rooted in large-scale data collection that frequently combines aspects of research, experimentation, and entertainment. Yet another mismatch between the worlds of Big Data research and IRB system are the
