Personal information management practices among the general public: analysis of questionnaire survey results in US and Japan

Aslib Journal of Information Management 2025

ISSN 20503806

Purpose: Personal information management (PIM) has evolved with advances in information technology. This study focused on how ordinary people use various technologies and tools for PIM practice in daily tasks. Design/methodology/approach: A web-based questionnaire survey was presented to 3,278 individuals in the United States and Japan between January and February 2022. The survey included 35 items for PIM activities assigned to three elements – task, format and management level – and three items for demographic data. Findings: Descriptive analysis showed that the use of digital format exceeded that of paper format in PIM activities. However, the paper format was preferred for certain tasks and among older age groups. In terms of the management level, retrieving information without management was the most frequent. Hierarchical clustering identified six behavioral types of PIM activities: omnivorous, selective, early adopters, conservatism, minimalist and no PIM. The conservatism cluster mainly used the paper format, whereas the no PIM cluster had almost no PIM activity. This demonstrates the diversity in the adoption of PIM practices. Originality/value: This study provides a snapshot of the current state of PIM practices when digital tools are commonly accessible and categorizes the PIM practices of ordinary people in the two countries. The results indicated that some people tend to retrieve information on specific tasks without managing it in advance. Moreover, the rising use of generative AI has the potential to fundamentally change PIM practices. This study suggests that examining the effect of information technology on PIM practices could be an important topic for the future.

This study focuses on the significant role played by reusing datasets in promoting open science. This study reported on the process of developing dataset reuse pattern categories and verified that these categories could be used to identify the role of reusing datasets. Articles that cited the biomedical dataset of the Framingham Cohort were included in the sample. Two annotators assigned categories to the samples by checking titles, journal names, author information, purpose, description of the dataset, and statements of data in the body of the articles; 11 categories were identified. The analysis of the sample articles with assigned categories indicated that this category set can contribute to verifying the increasing diversity of reuse patterns, expanding research areas, and contributing to data-driven research by reusing data. This study serves as a testament to the advantages of data reuse and inspires researchers to consider the impacts of data sharing practices.

Initial insight into three modes of data sharing: Prevalence of primary reuse, data integration and dataset release in research articles

While data sharing has received research interest in recent times, its real status remains unclear, owing to its ambiguous concept. To understand the current status of data sharing, this study examined primary reuse, data integration, and dataset release as the actual practices of data sharing. A total of 963 articles, chosen from those published in 2018 and registered in the Web of Science global citation database, were manually checked. Existing data were reused in the mode of data integration (13.3%) as frequently as they were for the mode of primary reuse (12.1%). Dataset release was the least common mode (9.0%). The results show the variation in data sharing and indicate the need for standardization of data description in articles based on thorough registration and expansion in public data archives to close the loop that results in the virtuous cycle of research data.

Advantages of data reuse based on disciplinary diversity and citation count

The adaption of data sharing is an important process in open science. Prior studies pertaining to data sharing have focused on the data release; however, data reuse is also an important aspect. Although the advantages of data reuse have not yet been demonstrated, they have been expressed in different fields. We selected the most cited datasets in the Data Citation Index – the National Longitudinal Study of Adolescent to Adult Health (Add Health) and the Framingham Cohort – and identified articles that reused them to measure the disciplinary diversity among these articles, as well as advantage in terms of citation counts. Particularly, we identified 2,919 articles that reused the Add Health dataset published in 1,702 resources, indicating high disciplinary diversity. Articles reused that the Framingham Cohort dataset had higher citation counts than those in the journal Circulation from 2004 to 2010. Despite our limited analysis, these results indicate the advantages of data reuse.

Purpose: Information behavior has changed in recent years following the increase in economic activities based on access. Five types of information media use were categorized based on a previous study of ownership: ownership, quasi-ownership, and access types 1, 2, and 3. To clarify the current trends in media use, we conducted a survey of the current uses of four types of media: novels, nonfiction books, comics, and music. The respondents were categorized based on their information media use.Methods: An online panel survey was conducted in Japan with 1,030 participants who were counterbalanced by gender and age. The questions consist of 30 items related to media use, 5 related to physical media orientation, 3 related to frequency of media use, 2 related to possession and use of computer devices, and 10 related to personality.Results: Of the 30 questions on media use, more than half of the respondents answered “never/don’t know/no idea” to 27 questions. However, 41.9% of the respondents answered that they “very often/often” listen to music on free online video-sharing platforms such as YouTube. Seven clusters were identified based on hierarchical clustering from the answers for media use. The five clusters that indicated less use of information media were: “only YouTube,” “nonuser,” “library user,” “music subscription user,” and “ownership.” The two respondent clusters that used information media frequently were: “active user of all media” and “active user (mainly access type 3).” The characteristics of the clusters were discussed.

The purpose of this research is to identify topics in library and information science (LIS) using latent Dirichlet allocation (LDA) and to visualize the knowledge structure of the field as consisting of specific topics and its transition from 2000-2002 to 2015-2017. The full text of 1648 research articles from five peer-reviewed representative LIS journals in these two periods was analyzed by using LDA. A total of 30 topics in each period were labeled based on the frequency of terms and the contents of the articles. These topics were plotted on a two-dimensional map usingLDAvisand categorized based on their location and characteristics in the plots. Although research areas in some forms were persistent with which discovered in previous studies, they were crucial to the transition of the knowledge structure in LIS and had the following three features: (1) The Internet became the premise of research in LIS in 2015-2017. (2) Theoretical approach or empirical work can be considered as a factor in the transition of the knowledge structure in some categories. (3) The topic diversity of the five core LIS journals decreased from the 2000-2002 to 2015-2017.

Data integration as the major mode of data reuse

Sakai Y., Miyata Y., Yokoi K., Wang Y., Kurata K.

Proceedings of the Association for Information Science and Technology 57 ( 1 ) 2020.10

Data sharing has been emphasized in scientific research in the era of open science; however, the concept of data sharing is ambiguous, and the real situation of data sharing is unclear. One reason is that most studies focused on researchers' recognition, motivation, and other contributing factors and did not thoroughly discuss the actual practice of data sharing for preparing research articles. To explicitly understand the current status of data sharing, the authors considered and investigated primary reuse, data integration, and data release distinctively as the actual practices of data sharing. A total of 237 articles published in 2018 and registered in the Web of Science global citation database were manually checked. Unlike the scarcity of data reuse (8.0%) or data release (5.1%), existing data were most frequently reused in the form of data integration (20.7%). The result implies that further studies on detailed data reuse are required to clarify the concept of data sharing.
