Automated Classification to Improve the Efficiency of Weeding Library Collections     

Kiri L. Wagstaff  Geoffrey Z. Liu 《The Journal of Academic Librarianship》2018,44(2):238-247

Previous studies have shown that weeding a library collection benefits patrons and increases circulation rates. However, the time required to review the collection and make weeding decisions presents a formidable obstacle. This study empirically evaluated methods for automatically classifying weeding candidates. A data set containing 80,346 items from a large-scale weeding project running from 2011 to 2014 at Wesleyan University was used to train six machine learning classifiers to predict a weeding decision of either ‘Keep’ or ‘Weed’ for each candidate. The study found statistically significant agreement (p?=?0.001) between classifier predictions and librarian judgments for all classifier types. The naive Bayes and linear support vector machine classifiers had the highest recall (fraction of items weeded by librarians that were identified by the algorithm), while the k-nearest-neighbor classifier had the highest precision (fraction of recommended candidates that librarians had chosen to weed). The variables found to be most relevant were: librarian and faculty votes for retention, item age, and the presence of copies in other libraries.  相似文献   

Disaster philanthropy: Exploring the power and influence of for-profit philanthropy in education development during pandemic times     

《International Journal of Educational Development》2021

This article contributes a conceptual analysis of the power and influence of for- profit philanthropy on educational development during pandemic times. Through highlighting for-profit philanthropy, describing its relevance to educational development, and drawing attention to four aspects that are under-examined as for- profit philanthropists enact their philanthropic agendas in response to the COVID- 19 pandemic, disaster philanthropy is presented as a window of opportunity for elite donors to enact changes in public education based on their distinct donor and institutional agendas. Implications for educational development are discussed including shifts in power, definitions and public vs. private returns.  相似文献   

Citizens as planners: Harnessing information and values from the bottom-up     

《International Journal of Information Management》2017,37(3):111-113

In this paper, we focus on understanding the critical role of everyday citizen in planning and policy-related issues in their city enabled by the newly emerging technological platforms such as mobile-based application and internet-based participatory platforms. The interest and capability of citizens to use and benefit from such online platforms that facilitate urban planning has grown in recent times, which makes it important to study the nature of these platforms and civic engagement that is facilitated through them. We study three such platforms and provide policy recommendations to urban planners based on our analyses of the platforms.  相似文献
