Abstract
Purpose
In order to estimate the value of semi-automated subject indexing in operative library catalogues, the study aimed to investigate five different automated implementations of an open source software package on a large set of Swedish union catalogue metadata records, with Dewey Decimal Classification (DDC) as the target classification system. It also aimed to contribute to the body of research on aboutness and related challenges in automated subject indexing and evaluation.
Design/methodology/approach
On a sample of over 230,000 records with close to 12,000 distinct DDC classes, an open source tool Annif, developed by the National Library of Finland, was applied in the following implementations: lexical algorithm, support vector classifier, fastText, Omikuji Bonsai and an ensemble approach combing the former four. A qualitative study involving two senior catalogue librarians and three students of library and information studies was also conducted to investigate the value and inter-rater agreement of automatically assigned classes, on a sample of 60 records.
Findings
The best results were achieved using the ensemble approach that achieved 66.82% accuracy on the three-digit DDC classification task. The qualitative study confirmed earlier studies reporting low inter-rater agreement but also pointed to the potential value of automatically assigned classes as additional access points in information retrieval.
Originality/value
The paper presents an extensive study of automated classification in an operative library catalogue, accompanied by a qualitative study of automated classes. It demonstrates the value of applying semi-automated indexing in operative information retrieval systems.

Abstract
Purpose
The purpose of this study is to identify motivations for the uptake of crowdfunding by micro-entrepreneurs in an emerging economy and the extent to which these vary by entrepreneur characteristics, sector and crowdfunding model.
Design/methodology/approach
The authors conduct qualitative analyses of data collected in interviews with 57 micro-entrepreneurs in Morocco, all of whom used crowdfunding in fundraising.
Findings
The authors identify six key motives for crowdfunding adoption by micro-entrepreneurs including financing needs, legitimacy seeking, sense of achievement, network-building, entrepreneurial and marketing competence enhancements. They also find evidence for moderation effects of fundraiser characteristics on likelihood of adoption, including gender, age, education, training experience and sectoral affiliation. Furthermore, the authors show that the relative importance of different motives varies by the type of crowdfunding model used.
Originality/value
The original aspects of the study include the examination of adoption motives in an emerging market context and the distinguishing between entrepreneurs’ adoption motives based on different gender, age, education, training experience, sectoral affiliation and crowdfunding model used. Moreover, the authors show that enhancement of competencies is a more dominant motive in the emerging market context than mentioned in earlier studies in developed contexts.
