Toward Privacy Standards Based on Empirical Studies

April 28, 2011
Author(s)
Serge M. Egelman, Erika McCallister
In this paper, we argue that if privacy standards are created to guide “do-not-track” technologies, it is imperative that these standards are created with the primary stakeholder in mind: the data subject. Previous privacy and security standards have been

TRECVID 2010 - An Overview of the Goals, Tasks, Data, Evaluation Mechanisms, and Metrics

April 15, 2011
Author(s)
Paul D. Over, George M. Awad, Jonathan G. Fiscus, Brian Antonishek, Martial Michel, Alan Smeaton, Wessel Kraaij, Georges Quenot
The TREC Video Retrieval Evaluation (TRECVID) 2010 was a TREC-style video analysis and retrieval evaluation, the goal of which remains to promote progress in content-based exploitation of digital video via open, metrics-based evaluation. Over the last 10

A Feature-preserved Canonical Form for Non-rigid 3D Meshes

April 14, 2011
Author(s)
Zhouhui Lian, Afzal A. Godil
Measuring the dissimilarity between non-rigid objects is a challenging problem in 3D shape retrieval. One potential solution is to construct the models’ 3D canonical forms (i.e., isometry-invariant representations in 3D Euclidean space) on which any rigid

Salient Local 3D Features for 3D Shape Retrieval

April 7, 2011
Author(s)
Afzal A. Godil, Asim Wagan
In this paper we describe a new formulation for the 3D salient local features based on the voxel grid inspired by the Scale Invariant Feature Transform (SIFT). We use it to identify the salient keypoints (invariant points) on a 3D voxelized model and

SHREC11 Track: Shape Retrieval on Non-rigid 3D Watertight Meshes

April 7, 2011
Author(s)
Zhouhui Lian, Afzal A. Godil
Non-rigid 3D shape retrieval has become an important research topic in content-based 3D object retrieval. The aim of this track is to measure and compare the performance of non-rigid 3D shape retrieval methods implemented by different participants around

NIST Workshop on Ontology Evaluation (NISTIR 7774)

April 1, 2011
Author(s)
Ram D. Sriram, Conrad E. Bock, Fabian M. Neuhaus, Evan K. Wallace, Mary C. Brady, Mark Musen, Joanne Luciano
The National Institute for Standards and Technology sponsored a workshop in October, 2007, on the subject of ontology evaluation. An international group of invited experts met for two days to discuss problems in measuring ontology quality. The workshop

Thoughts on Higher Education and Scientific Research

March 22, 2011
Author(s)
Jeffrey M. Voas, George Hurlburt, Keith Miller, Phillip Laplante, Bret Michael
The notion of a "tipping point" isn't new, al though the concept has relevance in differing ways. Academia seems to be at a tipping point, whereby the steady state of disciplinary specialization is about to give way to an interdisciplinary, collaborative

Efficient Motion Vector Interpolation for Error Concealment of H.264/AVC

March 1, 2011
Author(s)
Hamid Gharavi
In video communications the compressed video stream is very likely to be corrupted by channel errors. In order to combat these channel errors, many methods have been proposed. In this paper, a new method for motion vectors (MVs) interpolation with the help

National Checklist Program for IT Products Guidelines for Checklist Users and Developers

February 25, 2011
Author(s)
Stephen D. Quinn, Murugiah P. Souppaya, Melanie Cook, Karen Scarfone
Special Publication 800-70 Revision 2 - National Checklist Program for IT Products Guidelines for Checklist Users and Developers describes security configuration checklists and their benefits, and it explains how to use the NIST National Checklist Program

A Comparative Analysis of Cascade Measures for Novelty and Diversity

February 10, 2011
Author(s)
Ian M. Soboroff, Charles L. Clarke, Nick Craswell, Azin Ashkan
Traditional editorial effectiveness measures, such as nDCG, remain standard for Web search evaluation. Unfortunately, these traditional measures can inappropriately reward re- dundant information and can fail to reflect the broad range of user needs that

Calibration and uncertainty assessment for certified reference gas mixtures

January 13, 2011
Author(s)
Franklin R. Guenther, Antonio M. Possolo
The method to build an analysis function described in ISO 6143, Gas analysis - Comprarison methods for determining and checking the composition of calibration gas mixtures, is extended to recognize the typically small number of instrumental readings

Benchmarks, Performance Evaluation and Contests for 3D Shape Retrieval

December 20, 2010
Author(s)
Afzal A. Godil, Zhouhui Lian, Helin Dutagaci
Benchmarking of 3D Shape retrieval allows developers and researchers to compare the strengths of different algorithms on a standard dataset. Here we discuss the different steps involved in developing a benchmark and some of the issues involved. We then

Free and Open Source Software

December 13, 2010
Author(s)
Keith Miller, Jeff Voas, Tom Costello
In this paper, free and open source software are discussed. Open source is an intellectual property destroyer. Nothing could be worse than this for the software business and the intellectual-property business. Microsoft has an official open source presence

Mobile Applications: the Fifth Cycle

December 13, 2010
Author(s)
George Hurlburt, Jeff Voas, Keith Miller
Using the analogy of an existing smart car, this paper explores Power to the Edge , where the edge is commercial mobile computing. The world is poised for a 5th Cycle of computer capability, this time focused on the burgeoning phenomena of mobile computing

A New Analysis of the False-Positive Rate of a Bloom Filter

October 15, 2010
Author(s)
Ken Christensen, Allen L. Roginsky, Miguel Jimeno
A Bloom filter is a space-efficient data structure used for probabilistic set membership testing. When testing an object for set membership, a Bloom filter may give a false positive. The analysis of the false positive rate is key to understanding the Bloom

In Trust we Trust

October 14, 2010
Author(s)
Keith Miller, Jeff Voas, Phillip Laplante
The term trust has had a well understood definition for centuries. However after e-trust came along, and then cloud, where e-trust is not sufficient due to the non-touchability of a public cloud, the need to reconsider what trust means for a public cloud

Further Studies of Bootstrap Variability for ROC Analysis on Large Datasets

October 11, 2010
