Chronology: Data-driven Sports Image Indexing Research

Introduction

This chronology reports on research (theory, empirical, and grant/patent related), teaching, service, and entrepreneurial activities investigating data-driven sports image indexing that were led by Steven L. MacCall, PhD, associate professor in the School of Library and Information Studies (SLIS) at the University of Alabama since 2013.

Indexing research is a long standing area for information science investigators. Applications of such research include the improvement of systems design (efficiency and effectiveness) as well as informing the teaching of information professionals to better prepare them for the technological intensities of the modern metadata work environment. In a professional school such as SLIS, it is vitally important that full time faculty members have teaching and service activities informed by their research.

Current Research Questions

One would expect that research questions would evolve over time, and in that spirit, these are the present day global research questions presently under investigation in this research program:

1. Effectiveness: Can data-driven indexing methods serve a maximal indexing objective in which all identifiable named entities are indexed based on all of their observable features and attributes?
2. Efficiency: Can data-driven indexing methods scale to meet the maximal indexing objective and also match the rate in which current sports images (photo and video) that are captured by digital cameras and historical sports images (photo and video) that are digitized from the historical record?
3. Integration: Can current born digital sports images and digitized historical images be indexed in such a way that results in a single database application rather than in multiple silos?

Working Software Demonstrations

Semantic Indexing Era: Wikibase Software (2018 to present)

Since summer of 2018 (see entry for 2018 in chronology below), I have been able to switch my research and development platform from conventional image indexing software (see subsection just below) to Wikibase, which is more current state-of-the-art linked data research and development software that supports experiments in semantic indexing.

Since 2018, we have achieved the following research milestones (follow links for more information about each):

1. Games from the 2017 Alabama Crimson Tide football season: We have completed the semantic indexing of all games from the 2017 Alabama Crimson Tide football season using a semantic indexing method that incorporates JSON-formatted statistical play-by-play datasets into a semantic indexing process via the creation of a semi-automated data processing pipeline. (This effort was partially funded by two 2018 grants that we received; see chronology.)
2. Games from the 1992 Alabama Crimson Tide football season: 1992 Alabama football season: semantically indexed two games (funded by RGC grant - see entry for grant under 2018 below

Conventional Indexing Era: Omeka and ContentDM Software (2008 to 2018)

During this period, SLIS students in my annual spring semester Metadata course (LS 566) benefited from the application of my research as I was able to use it to inform my teaching. Specifically, my research served as the basis for their course project work, which involved the application of indexing theories by way of applying the standard/conventional approach to the indexing of a set of images. These images were provided by Ken Gaddy, Director of the Paul W. Bryant Museum, and they were both digitized black and white photos of Alabama Crimson Tide football games from the 1975 season and also born digital color images from the 2010 National Championship game.

The indexing of these images was accomplished using two different software applications.

1. Omeka software (2011-2018): Here is a representative example of the end result of the last of such indexing projects from the Spring 2018 semester of this course.
2. ContentDM (2008-2010)
