Current research on theory and practice of digital libraries: best papers from TPDL 2019 & 2020
(2022)
This volume presents a special issue on selected papers from the 2019 & 2020 editions of the International Conference on Theory and Practice of Digital Libraries (TPDL). They cover different research areas within Digital Libraries, from Ontology and Linked Data to quality in Web Archives and Topic Detection. We first provide a brief overview of both TPDL editions, and we introduce the selected papers.

The Specialized Information Service Biodiversity Research (BIOfid) has been launched to mobilize valuable biological data from printed literature hidden in German libraries for over the past 250 years. In this project, we annotate German texts converted by OCR from historical scientific literature on the biodiversity of plants, birds, moths and butterflies. Our work enables the automatic extraction of biological information previously buried in the mass of papers and volumes. For this purpose, we generated training data for the tasks of Named Entity Recognition (NER) and Taxa Recognition (TR) in biological documents. We use this data to train a number of leading machine learning tools and create a gold standard for TR in biodiversity literature. More specifically, we perform a practical analysis of our newly generated BIOfid dataset through various downstream-task evaluations and establish a new state of the art for TR with 80.23% F-score. In this sense, our paper lays the foundations for future work in the field of information extraction in biology texts.

In keeping with the views of its guru, Stephen Harnard, the open access movement is only prepared to discuss the two models of the "green road" and the "golden road" as sole alternatives for the future of scientific publishing. The "golden road" is put forward as the royal road for solving the journals crisis. However, no one has drawn attention to the fact that the golden road represents a purely socialist solution to a free-market problem and thus continues the "samizdat" tradition of underground literature in the former Eastern bloc. The present paper reveals the alarmingly low level at which the open access movement intends to publish top-class results from science and research, and the low degree of professionalism with which they are satisfied.
In this increasingly complex world of learned information delivery and discovery - is it possible that the "free lunch" the Publishing world worries about could come true? Although Open Access and Institutional Repositories have not (yet) created the "scorched earth" effect many were predicting, they are slowly and inevitably gaining momentum. Broader access to top-level information via Google (and others) does indeed appear to be "good enough" for many in their search for content. But you rarely get food for free in a good quality restaurant. You pay for the selection, preparation, speed and expertise of the delivery. At the soup kitchen the food can often be filling - but the queue will be long, the wait even longer and there is no chance of silver service or à la carte. If you are unfortunate enough to have little choice then this may be a great solution. Others will be willing to pay for a more satisfactory meal. As in all aspects of life, diversification and specialisation are fundamental forces. The publishing community in the years to come will continue to develop its offerings for a variety of needs that require more than just broth. To stretch the analogy, the ongoing presence of tap water in our lives has done little to halt the extraordinary rise of bottled water as part of our staple diet. Business reality will continue to settle these types of debate; my bet is that the commercial publishers see a role as providing information that commands an intrinsic value proposition to enough customers to remain economically viable for some time to come. Inspired by the comments and ideas expounded by Dr. James O'Donnell of Georgetown University on the liblicense listserv on 20th July this year, this paper will look to expand on the analogy and identify the good, the bad - but importantly the difference in information quality and access that will result in the radically changed (but still co-existent) information landscape of tomorrow.
The Specialised Information Service Performing Arts (SIS PA) is part of a funding programme by the German Research Foundation that enables libraries to develop tailor-made services for individual disciplines in order to provide researchers direct access to relevant materials and resources from their field. For the field of performing arts, the SIS PA is aggregating metadata about theater and dance resources from currently, mostly, German-speaking cultural heritage institutions in a VuFind-based search portal.
In this article, we focus on metadata quality and its impact on the aggregation workflow by describing the different, possibly data provider-specific, process stages of improving data quality in order to achieve a searchable, interlinked knowledge base. We also describe lessons learned and limitations of the process.
The Frankfurt University Library possesses one of the outstanding Africana Collections in continental Europe; its regional anddisciplinary scope is unique in Germany. Today about 5,000 new acquisitions a year have accumulated over 200,000 items on Africa south of the Sahara. Some 50,000 historical and rare photographs are fully digitized and freely accessible. Together with a collection of around 18,000 books stemming from the collections of the German Colonial Society at the end of the 19th and the beginning of the 20th century they constitute the historical foundations of the collection. Recently the University Library Frankfurt and the library of the GIGA Institute of African Affairs, Hamburg, started the project ilissAfrica (internet library sub-Saharan Africa), a central subject gateway for online resources and a powerful tool for bibliographic research. These new services will be indispensable for researchers and librarians of African Studies and will promote African studies worldwide.
The paper presents an overview about some of the international relevant projects of digital resources in Germany. Online presentations of primary sources, e.g. photographic material, and bibliographic tools supporting research, such as cross searching, will be presented as potential partners of resource sharing with North America. Not only the possibility of cooperation will be sketched, but also necessary preliminary work and some obstacles will be outlined. This report is accompanied by a short characterization of African studies in Germany and the status quo of Open Access-initiatives.
New projects, services and collaborations have recently brought the infrastructural services for African Studies a big step forward. This report gives an account of new subject gateways and digitisation projects. It discusses recent European cooperation ventures in the field of librarianship. Additionally, new developments and services of the Africa Collection at Frankfurt University Library are presented, which help to address the changing needs of researchers and to handle information overload, while keeping up with the latest developments. Nevertheless, the fragmentation and compartmentalisation of the different services still hinder more integrated information services.
