Evaluation campaigns and TRECVid

The TREC Video Retrieval Evaluation (TRECVid)is an international benchmarking activity to encourage research in video information retrieval by providing a large test collection, uniform scoring procedures, and a forum for organizations 1 interested in comparing their results. TRECVid completed its fifth annual cycle at the end of 2005 and in 2006 TRECVid will involve almost 70 research organizations, universities and other consortia. Throughout its existence, TRECVid has benchmarked both interactive and automatic/manual searching for shots from within a video corpus,automatic detection of a variety of semantic and low-level video features, shot boundary detection and the detection of story boundaries in broadcast TV news. This paper will give an introduction to information retrieval (IR) evaluation from both a user and a system perspective, high-lighting that system evaluation is by far the most prevalent type of evaluation carried out. We also include a summary of TRECVid as an example of a system evaluation bench-marking campaign and this allows us to discuss whether such campaigns are a good thing or a bad thing. There are arguments for and against these campaigns and we present some of them in the paper concluding that on balance they have had a very positive impact on research progress.

TRECVID 2019: An evaluation campaign to benchmark Video Activity Detection, Video Captioning and Matching, and Video Search & retrieval

The TREC Video Retrieval Evaluation (TRECVID) 2019 was a TREC-style video analysis and retrieval evaluation, the goal of which remains to promote progress in research and development of content-based exploitation and retrieval of information from digital video via open, metrics-based evaluation. Over the last nineteen years this effort has yielded a better understanding of how systems can effectively accomplish such processing and how one can reliably benchmark their performance. TRECVID has been funded by NIST (National Institute of Standards and Technology) and other US government agencies. In addition, many organizations and individuals worldwide contribute significant time and effort. TRECVID 2019 represented a continuation of four tasks from TRECVID 2018. In total, 27 teams from various research organizations worldwide completed one or more of the following four tasks: 1. Ad-hoc Video Search (AVS) 2. Instance Search (INS) 3. Activities in Extended Video (ActEV) 4. Video to Text Description (VTT) This paper is an introduction to the evaluation framework, tasks, data, and measures used in the workshop.

TRECVID 2006 Overview

The TREC Video Retrieval Evaluation (TRECVID) 2006 represents the sixth running of a TREC-style video retrieval evaluation, the goal of which remains to promote progress in content-based retrieval from digital video via open, metrics-based evaluation. Over time this effort should yield a better understanding of how systems can effectively accomplish such retrieval and how one can reliably benchmark their performance. TRECVID is funded by the Disruptive Technology Office (DTO) and the National Institute of Standards and Technology (NIST) in the United States. Fifty-four teams (twelve more than last year) from various research organizations — 19 from Asia, 19 from Europe, 13 from the Americas, 2 from Australia and 1 Asia/EU team — participated in one or more of four tasks: shot boundary determination, high-level feature extraction, search (fully automatic, manually assisted, or interactive) or pre-production video management. Results for the first 3 tasks were scored by NIST using manually created truth data. Complete manual annotation of the test set was used for shot boundary determination. Feature and search submissions were evaluated based on partial manual judgments of the pooled submissions. For the fourth exploratory task participants evaluated their own systems. Test data for the search and feature tasks was about 150 hours (almost twice as large as last year) of broadcast news video in MPEG-1 format from US (NBC, CNN, MSNBC), Chinese (CCTV4, PHOENIX, NTDTV), and Arabic (LBC, HURRA) sources that had been collected in November 2004. The BBC Archive also provided 50 hours of “rushes” pre-production travel video material with natural sound, errors, etc. against which participants could experiment and try to demonstrate functionality useful in managing and mining such material.

The scholarly impact of TRECVid (2003-2009)

This paper reports on an investigation into the scholarly impact of the TRECVid (Text Retrieval and Evaluation Conference, Video Retrieval Evaluation) benchmarking conferences between 2003 and 2009. The contribution of TRECVid to research in video retrieval is assessed by analyzing publication content to show the development of techniques and approaches over time and by analyzing publication impact through publication numbers and citation analysis. Popular conference and journal venues for TRECVid publications are identified in terms of number of citations received. For a selection of participants at different career stages, the relative importance of TRECVid publications in terms of citations vis a vis their other publications is investigated. TRECVid, as an evaluation conference, provides data on which research teams ‘scored’ highly against the evaluation criteria and the relationship between ‘top scoring’ teams at TRECVid and the ‘top scoring’ papers in terms of citations is analyzed. A strong relationship was found between ‘success’ at TRECVid and ‘success’ at citations both for high scoring and low scoring teams. The implications of the study in terms of the value of TRECVid as a research activity, and the value of bibliometric analysis as a research evaluation tool, are discussed. © 2011 Wiley Periodicals, Inc.

The TREC VIdeo Retrieval Evaluation (TRECVID): A Case Study and Status Report

The TREC Video Retrieval Evaluation (TRECVID) is an annual international effort, funded by the US Advanced Research and Development Agency (ARDA) and the National Institute of Standards and Technology (NIST) to promote progress in content-based retrieval from digital video via open, metrics-based evaluation. Now beginning its fourth year, TRECVID aims over time to develop both a better understanding of how systems can effectively accomplish video retrieval and how one can reliably benchmark their performance. This paper is a case study in the development of video retrieval systems and their evaluation as well as a report on the TRECVID status to-date. After an introduction to the evolution of TRECVID over the past 3 years, we report on the most recent evaluation TRECVID 2003 in terms of the 4 tasks (shot boundary determination, high-level feature extraction, story segmentation and classification, search), the data (133 hours of US television news), the measures, the results obtained, and the approaches taken by some of the 24 participating groups.
