TRECVID 2012 -- An Overview of the Goals, Tasks, Data, Evaluation Mechanisms, and Metrics

April 1, 2013
Author(s)
Paul D. Over, Jonathan G. Fiscus, Gregory A. Sanders, Barbara L. Shaw, Martial Michel, George Awad, Alan Smeaton, Wessel Kraaij, Georges Quenot
The TREC Video Retrieval Evaluation (TRECVID) 2012 was a TREC-style video analysis and retrieval evaluation, the goal of which was to promote progress in content-based exploitation of digital video via open, metrics-based evaluation. TRECVID 2012

Building Quantum Computers

January 22, 2013
Author(s)
Emanuel H. Knill
Abstract: In theory, quantum computers can be used to efficiently factor numbers, quadratically speed up many search and optimization problems, and enable currently impossible physics simulations. At first, quantum states appeared to be too fragile for

Evaluating Real-Time Search over Tweets

December 10, 2012
Author(s)
Ian M. Soboroff, Dean P. McCullough, Jimmy Lin, Craig Macdonald, Iadh Ounis, Richard McCreadie
Twitter offers a phenomenal platform for the social sharing of information. We describe new resources that have been created in the context of the Text Retrieval Conference (TREC) to support the academic study of Twitter as a real-time information source

A Reference Modulated Scatterer for ISO18000-6 UHF Tag Testing

November 15, 2012
Author(s)
David R. Novotny, Daniel G. Kuester, Jeffrey R. Guerrieri
We present a method for measuring Ultra-High Frequency Radio-Frequency Identification (UHF RFID) tag differential RCS that has the potential for being easier and more accurate than current and proposed methods [1-2]. This method is based on accurately

A comparison of methods for Non-rigid 3D shape retrieval

September 26, 2012
Author(s)
Zhouhui Lian, Afzal A. Godil
Non-rigid 3D shape retrieval has become an active and important research topic in content-based 3D object retrieval. The aim of this paper is to measure and compare the performance of state-of-the-art methods for non-rigid 3D shape retrieval. The paper

An evaluation of local shape descriptors for 3D shape retrieval

September 26, 2012
Author(s)
Afzal A. Godil, Sarah Y. Tang
As the usage of 3D models increases, so does the importance of developing accurate 3D shape retrieval algorithms. A common approach is to calculate a shape descriptor for each object, which can then be compared to determine two objects’ similarity. However

Data Quality for High Content Screening

September 3, 2012
Author(s)
YaShian Li-Baboud, Oleg Aulov, Peter Bajcsy
TO HAVE CONFIDENCE IN THE KNOWLEDGE GLEANED FROM DATA, IT IS ESSENTIAL TO VERIFY THE QUALITY OF THE DATA SOURCES AND TO HAVE A MEANS OF QUANTIFYING THE POTENTIAL UNCERTAINTIES DUE TO THE QUALITY OF DATA FOR MAKING CRITICAL, INTELLIGENT DECISIONS. HIGH

Overview of the TREC-2010 Blog Track

August 15, 2012
Author(s)
Ian M. Soboroff, Iadh Ounis, Craig Macdonald
The Blog track aims to investigate the information seeking behavior in the blogosphere. The track was initiated in 2006, and has used an incremental approach in tackling several search tasks by their level of difficulty. In TREC 2010, the track has

Mobile Application Device Power Usage Measurements

July 31, 2012
Author(s)
Rahul Murmuria, Jeffrey Medsger, Angelos Stavrou, Jeff Voas
Reducing power consumption has become a crucial design tenet for both mobile and other small computing devices that are not constantly connected to a power source. However, unlike devices that have a limited and predefined set of functionality, recent

Information Retrieval on the Blogosphere

July 30, 2012
Author(s)
Ian M. Soboroff, Rodrygo Santos, Craig Macdonald, Richard McCreadie, Iadh Ounis
Blogs have recently emerged as a new open, rapidly evolving and reac- tive publishing medium on the Web. Rather than managed by a central entity, the content on the blogosphere—the collection of all blogs on the Web—is produced by millions of independent

Feature-preserved 3D Canonical Form

July 28, 2012
Author(s)
Afzal A. Godil, Zhouhui Lian
Abstract 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 domain) on which

Conformance of Image Features to Classifier Assumptions

July 27, 2012
Author(s)
Julien M. Amelot, Peter Bajcsy, Mary C. Brady
Cell measurements are derived frequently from the results of pixel classification and contiguous region segmentation of microscopy images. Image segmentation is accomplished by classifying image pixels based on high dimensional image features computed from

A Restricted English for Constructing Ontologies (RECON)

July 10, 2012
Author(s)
Edward J. Barkmeyer Jr., Andreas K. Mattas
Verifying correctness of stated facts, rules, and term definitions for an industrial domain of work requires the contributions of experts in the domain. Conversely, use of automated reasoning technologies to assist in making industry decisions and

A New Convexity Measurement for 3D Meshes

June 16, 2012
Author(s)
Afzal A. Godil, Zhouhui Lian
This paper presents a novel convexity measurement for 3D meshes. The new convexity measure is calculated by minimizing the ratio of the summed area of valid regions in a mesh’s six views, which are projected on faces of the bounding box whose edges are

The Internet of Things: A Reality Check

June 11, 2012
Author(s)
George Hurlburt, Jeff Voas, Keith Miller
The short persepctive explains the concept behind Internet of Things (IoT). The publication is a perspectives piece for an IEEE magazine and not intended to be technical. This is intended to be published in a specific column in the magazine.

Assessing the Effect of Inconsistent Assessors on Summarization Evaluation

June 8, 2012
Author(s)
Karolina K. Owczarzak, Peter Rankel, Hoa T. Dang, John M. Conroy
We investigate the consistency of human assessors involved in summarization evaluation to understand its effect on system ranking and automatic evaluation techniques. Using Text Analysis Conference data, we measure annotator consistency based on human

Cloud Computing Synopsis and Recommendations
