"Content-Based Video Retrieval in Historical Collections of the German Broadcasting Archive"

Posted in Digital Archives and Special Collections, Digital Curation & Digital Preservation, Digital Media on February 17th, 2017

Markus Mühling et al. have self-archived "Content-Based Video Retrieval in Historical Collections of the German Broadcasting Archive."

Here's an excerpt:

The German Broadcasting Archive (DRA) maintains the cultural heritage of radio and television broadcasts of the former German Democratic Republic (GDR). The uniqueness and importance of the video material stimulates a large scientific interest in the video content. In this paper, we present an automatic video analysis and retrieval system for searching in historical collections of GDR television recordings. It consists of video analysis algorithms for shot boundary detection, concept classification, person recognition, text recognition and similarity search. The performance of the system is evaluated from a technical and an archival perspective on 2,500 hours of GDR television recordings

"ArchiveSpark: Efficient Web Archive Access, Extraction and Derivation"

Posted in Digital Archives and Special Collections, Digital Curation & Digital Preservation on February 7th, 2017

Helge Holzmann, Vinay Goel, and Avishek Anand have self-archived "ArchiveSpark: Efficient Web Archive Access, Extraction and Derivation."

Here's an excerpt:

Web archives are a valuable resource for researchers of various disciplines. However, to use them as a scholarly source, researchers require a tool that provides efficient access to Web archive data for extraction and derivation of smaller datasets. Besides efficient access we identify five other objectives based on practical researcher needs such as ease of use, extensibility and reusability.

Towards these objectives we propose ArchiveSpark, a framework for efficient, distributed Web archive processing that builds a research corpus by working on existing and standardized data formats commonly held by Web archiving institutions. Performance optimizations in ArchiveSpark, facilitated by the use of a widely available metadata index, result in significant speed-ups of data processing. Our benchmarks show that ArchiveSpark is faster than alternative approaches without depending on any additional data stores while improving usability by seamlessly integrating queries and derivations with external tools.

"The Devil’s Shoehorn: A Case Study of EAD to ArchivesSpace Migration at a Large University"

Posted in Digital Archives and Special Collections, Open Source Software on February 1st, 2017

Dave Mayo and Kate Bowers have published "The Devil's Shoehorn: A Case Study of EAD to ArchivesSpace Migration at a Large University" in the Code4Lib Journal.

Here's an excerpt:

A band of archivists and IT professionals at Harvard took on a project to convert nearly two million descriptions of archival collection components from marked-up text into the ArchivesSpace archival metadata management system. Starting in the mid-1990s, Harvard was an alpha implementer of EAD, an SGML (later XML) text markup language for electronic inventories, indexes, and finding aids that archivists use to wend their way through the sometimes quirky filing systems that bureaucracies establish for their records or the utter chaos in which some individuals keep their personal archives. These pathfinder documents, designed to cope with messy reality, can themselves be difficult to classify. Portions of them are rigorously structured, while other parts are narrative. Early documents predate the establishment of the standard; many feature idiosyncratic encoding that had been through several machine conversions, while others were freshly encoded and fairly consistent. In this paper, we will cover the practical and technical challenges involved in preparing a large (900MiB) corpus of XML for ingest into an open-source archival information system (ArchivesSpace). This case study will give an overview of the project, discuss problem discovery and problem solving, and address the technical challenges, analysis, solutions, and decisions and provide information on the tools produced and lessons learned.

"Bridging Technologies to Efficiently Arrange and Describe Digital Archives: The Bentley Historical Library’s ArchivesSpace-Archivematica-DSpace Workflow Integration Project"

Posted in Digital Archives and Special Collections, Digital Curation & Digital Preservation, DSpace, Institutional Repositories, Open Source Software on February 1st, 2017

Max Eckard, Dallas Pillen and Mike Shallcross have published "Bridging Technologies to Efficiently Arrange and Describe Digital Archives: The Bentley Historical Library's ArchivesSpace-Archivematica-DSpace Workflow Integration Project" in the Code4Lib Journal.

Here's an excerpt:

In recent years, ArchivesSpace and Archivematica have emerged as two of the most exciting open source platforms for working with digital archives. The former manages accessions and collections and provides a framework for entering descriptive, administrative, rights, and other metadata. The latter ingests digital content and prepares information packages for long-term preservation and access. In October 2016, the Bentley Historical Library wrapped up a two-year, $355,000 grant from the Andrew W. Mellon Foundation to partner with the University of Michigan Library on the integration of these two systems in an end-to-end workflow that will include the automated deposit of content into a DSpace repository. This article provides context of the project and offers an in-depth exploration of the project’s key development tasks, all of which were provided by Artefactual Systems, the developers of Archivematica (code available at https://github.com/artefactual-labs/appraisal-tab).

"Development of a Scale for Measuring Perceptions of Trustworthiness for Digitized Archival Documents"

Posted in Digital Archives and Special Collections, Digital Curation & Digital Preservation, Digital Repositories on May 22nd, 2015

Devan Rays Donaldson has self-archived "Development of a Scale for Measuring Perceptions of Trustworthiness for Digitized Archival Documents."

Here's an excerpt:

This dissertation advances scholarship on trustworthiness in three ways. First, it revises an existing conceptual model for trustworthiness perception. Second, it creates an original measurement model for digitized archival document trustworthiness perception-the Digitized Archival Document Trustworthiness Scale (DADTS). Third, it contributes to a deeper understanding of the concept of trustworthiness by providing measurement of the concept in a way that is sensitive to its nuances.
