- The general aim of this paper is to explore the practice of subject indexing and classification of health information in public libraries. The pilot study encompasses two public libraries, each from a different European country, Croatia and Sweden: Zadar Public Library, and Växjö Public Library. The research questions are: 1) how important is the terminology for subject headings; and, 2) how many subject terms are enough to describe an information resource in a catalog record? The research was done in two phases. First, an exploratory evaluation of subject searching in the catalogs was conducted. Second, after the analysis of the catalogs, questions for interviews were formed. Four semi-structured interviews were conducted, two per library, of which one interview with a subject librarian and one with a reference librarian. Finally, a comparative analysis between the two libraries from the two countries was con- ducted. Results imply that the subject headings and classification used were very generic and did not cater for specific, topically narrower queries. Also, subject indexing was considered important, especially to the librarians for searching purposes through ensuring consistency in the catalog, thereby making it easier to find resources on the same topics.

Digital humanities : an exploration of a new programs in higher education and its meaning making by community partners

Konferensbidrag (refereegranskat)abstract
- As part of the Digital Humanities initiative at Linnaeus University, this exploratory study is aimed at gathering views and opinions from relevant stakeholders in the regional community in order to understand their perspective on Digital Humanities as a subject of study and the potential application of Digital Humanities to address local requirements. The ultimate purpose of the study was to inform the development of Digital Humanities at Linnaeus University in a way that would address genuine needs within society. The principal research question of the study was: "What views and opinions are there about Digital Humanities and how can they be exploited for the optimal benefit of the education and industry sectors of the local region of Småland?" A focus group interview of four stakeholders was conducted, each representing a different cultural institution in the region. The participants largely agreed that Digital Humanities could be used in optimal ways to engage people and end users in their work and social engagement. The Digital Humanities project could contribute and engage with wider society through schools, museums and other public platforms. However, the sustainability of the Digital Humanities project requires further study. Also, as a provider of higher education in Sweden, it was important to bear in mind that the proposed educational programme in the Digital Humanities needs to keep to the three pillars of Education, Research, and Engagement with Society as the primary components of their course development.

Digital Libraries for Open Knowledge : 23rd International Conference on Theory and Practice of Digital Libraries, TPDL 2019, Oslo, Norway, September 9–12, 2019, Proceedings
- 2019
-
Proceedings (redaktörskap) (refereegranskat)abstract
- This book constitutes the proceedings of the 23rd International Conference on Theory and Practice of Digital Libraries, TPDL 2019, held in Olslo, Norway, in September 2019. The 16 revised full papers,12 short papers and 18 poster papers presented were carefully reviewed and selected from 75 submissions. The general theme of TPDL 2019 was Connecting with Communities and so the papers attempt to facilitate establishing connections and convergences between diverse research communities such as Digital Humanities, Information Sciences and others that could benefit from ecosystems offered by digital libraries and repositories. To become especially useful to the diverse research and practitioner communities digital libraries need to consider special needs and requirements for effective data utilization, management and exploitation.

A framework for evaluating automatic indexing or classification in the context of retrieval
- 2016

Tidskriftsartikel (refereegranskat)abstract
- Tools for automatic subject assignment help deal with scale and sustainability in creating and enriching metadata, establishing more connections across and between resources and enhancing consistency. While some software vendors and experimental researchers claim the tools can replace manual subject indexing, hard scientific evidence of their performance in operating information environments is scarce. A major reason for this is that research is usually conducted in laboratory conditions, excluding the complexities of real-life systems and situations. The paper reviews and discusses issues with existing evaluation approaches such as problems of aboutness and relevance assessments, implying the need to use more than a single “gold standard” method when evaluating indexing and retrieval and proposes a comprehensive evaluation framework. The framework is informed by a systematic review of the literature on indexing, classification and approaches: evaluating indexing quality directly through assessment by an evaluator or through comparison with a gold standard; evaluating the quality of computer-assisted indexing directly in the context of an indexing workflow, and evaluating indexing quality indirectly through analyzing retrieval performance.

Konferensbidrag (refereegranskat)abstract
- With more and more digital collections of various information re- sources becoming available, also increasing is the challenge of assigning subject index terms and classes from quality knowledge organization systems. While the ultimate purpose is to understand the value of automatically produced Dewey Decimal Classification (DDC) classes for Swedish digital collections, the paper aims to evaluate the performance of two machine learning algorithms for Swe- dish catalogue records from the Swedish union catalogue (LIBRIS). The algo- rithms are tested on the top three hierarchical levels of the DDC. Based on a data set of 143,838 records, evaluation shows that Support Vector Machine with linear kernel outperforms Multinomial Naïve Bayes algorithm. Also, using keywords or combining titles and keywords gives better results than using only titles as input. The class imbalance where many DDC classes only have few records greatly affects classification performance: 81.37% accuracy on the training set is achieved when at least 1,000 records per class are available, and 66.13% when few records on which to train are available. Proposed future research involves an exploration of the intellectual effort put into creating the DDC to further improve the algorithm performance as commonly applied in string matching, and to test the best approach on new digital collections that do not have DDC assigned.
