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

Y Miyata, K Kurata, E Ishita, A Iwase, N Yoshida, J Wu, K Yamaoka

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.

International Conference on Asian Digital Libraries, 260-266 15494 LNCS 260 - 266 2025

ISSN 03029743

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.

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.

ISSN 03029743

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.

Factors affecting digital skills were analyzed using open data from the International Adult Power Survey (PIAAC: Programme for the International Assessment of Adult Competencies) conducted in 38 countries in 2011-2018. The number of correct answers (15,702 cases from 25 countries) to questions on problem solving ability (PSTRE: Problem Solving in Technology-Rich Environments) utilizing information technology (IT) that are supposed to reflect digital skills were used. The analysis procedure was as follows. 1. Comparison of the correct answer rates for PSTRE tasks in each country. 2. Factor analysis of 63 questions selected from background surveys (such as daily media use). 3. Regression analysis using the factor scores for selected factors, age, gender and educational background as the explanatory variable, and the number of correct answers to PSTRE for each respondent as the objective variable. The results for all 25 countries, Japan, and three countries in Northern Europe (Nordic countries) were grouped and analyzed. The results indicated that the correct answer rate for each question varied between countries, and the factors affecting the number of correct answers for the question varied between the three groups. In particular, age and educational background factors affected PSTRE in all groups, and there was no significant difference between genders in Japan and the three Nordic countries.

In today's digital age, daily reading may be becoming digital reading. To understand this possible shift from reading print media to reading digital media, we investigated reading behavior for 11 media and reading preferences between print and digital in different circumstances. In August 2012, an online survey was used to inquire about the reading behavior and preference of 1,755 participants, ranging in age from 18 to 69 years. The participants contained equal numbers of men and women from five age brackets. Our main finding was that approximately 70% of total reading time was spent on digital media and that preferences favored print media. Cluster analysis of reading time by media was used to categorize respondents into eight clusters, and a second cluster analysis on stated preference (digital or print) yielded six clusters. The correspondence analysis between reading behavior clusters and preference clusters revealed that there is a mismatch between reading behavior and stated preference for either print or digital media.

© 2017 ACM. Identifying factors that influence information retrieval skills can help us to understand search behavior and show what skills are required to conduct efficient and accurate searches. This paper describes a study in which relationship factors that influence the information retrieval skills of a cohort of 1,551 Japanese Internet users are investigated using a combination of survey methods, factor analysis, and structural equation modeling. Our factor analysis confirms the importance of three sub-skill groups that are similar to sub-skill groups that have been previously reported (i.e., formal Internet skills, operational skills, and assessment skills) and indicates the importance of a fourth group (which we call "search strategy skills"). Our structural equation model incorporates two novel factors that have not previously been studied in this context: critical thinking ability, and self-efficacy for the Internet and information retrieval. The results show that critical thinking ability and self-efficacy positively influence the information retrieval skill level, and age is found to be a negative influence. Contrary to previously reported results, little independent effect is seen from educational attainment.

This article explores the current status of presentations in academic conferences for research activities. We conducted a case study on academic conference Web sites as well as a questionnaire survey by e-mail. From the survey of 54 Web sites of academic societies, we found that they held academic conferences regularly and that the management of conferences by local executive committees tended to follow that of previous conferences. The questionnaire survey targeted the secretariats of academic societies; we analyzed the responses from 285 academic societies and obtained the following results. (1) A poster presentation was made at many conferences in the natural and medical sciences. (2) Most academic conferences employed a peer-review system. (3) Oral presentations only or oral presentation with handout were permitted in the humanities and social sciences. (4) A few academic societies recorded presentations in digital format and subsequently offered access to those recordings. Academic conferences have been regarded as an area of informal communication. Because presentations are included in academic conferences, they have not been formal research results. And then they should not be archived and made available in open access.

In this research, the information retrieval (IR) skills in web environment are newly defined as professional skills and knowledge for traditional information retrieval in conjunction with digital skills described by van Deursen. To assess the status of IR skills in Japan, an online questionnaire-based survey was conducted in August 2014. Ultimately, 1,551 participants responded. The results showed the following trends among the participants: (1) not using advanced search technique such as Boolean operator, (2) understanding the format of information on web, (3) carefully choosing search terms, (4) evaluating multiple search results based on certain evaluation criteria, and (5) feeling that they receive benefits from the Internet. Moreover, based on the hierarchical clustering analysis of their information retrieval skills, the participants were categorized into eight clusters. One of the clusters comprised the participants with highly performing IR skills. The characteristics of this cluster members included relatively younger generation, males, highly educated, high critical thinking ability, and high self-efficiency. Although this cluster members achieved the highest average scores on each IR skill, their scores on search technique skills were significantly less developed than those on other skills.

In this paper, we develop rules for the automatic detection of scientific papers from PDF files on the Web. We inspected the structure and elements of scientific papers and observed that scientific papers typically have certain basic elements and an IMRAD format. We examined 1,172 scientific papers on the Web. The results indicate that the papers share common elements such as title, authors, keyword, and references and 40% of the papers, which have an explicit structure, have an IMRAD or a similar format. We develop rules for automatic detection of scientific papers using information based on their structure and elements obtained from the inspection process. The rules are evaluated using English and Japanese PDF collections, which were compiled by random sampling from the Web and consisted of 20,000 files each. Random forest classifier is performed and an F-value of 0.74 is obtained for English PDF files and 0.53 for Japanese PDF files. These results indicate that the rules developed using the approach given in this study can detect scientific papers from PDF files on the Web.

© Springer International Publishing Switzerland 2014. Asteroids have some clues about the origin of the solar system. In recent years, asteroid exploration by surface explorers has been studied actively. Conventional rovers can move under microgravity environment, but the rovers have not considered thermal control. This paper proposes a novel mobility mechanism for a rover under microgravity environment along with temperature control. The effectiveness of the proposed rover is investigated by simulations and microgravity experiments.

A research project was conducted in which proper JAPAN/MARC bibliographic records for 158 major Japanese classical works were identified manually, since existing records contain little information about works included in the resources. This article reports on the detailed method used for work identification, including selecting works, obtaining the bibliographic records to be judged, and building the judgment criteria. The results of the work identification process are reported along with average numbers that indicate the characteristics of certain classics. The necessity of manual identification was justified through an evaluation of searches by author and/or title information in a conventional retrieval system. © Taylor & Francis Group, LLC.

The more the size of Web increases, the more serious the problem of the deep Web (the Web not accessible to search engines) becomes. McCown et al. (2006) and Hagedorn & Santelli (2008) surveyed extent of deep Web using metadata contained in institutional repositories. In this research, applying the method used in that previous work, we measured the extent of the deep Web on a larger scale using PDF file URLs contained in institutional repositories in Japan in September 2009. The results show that the coverage rate of major search engines (Google, Yahoo! and Bing) is 72%, leaving 28% as the maximum extent of the deep Web. And examination of the characteristics of the files revealed that dynamic URLs and longer URLs are associated with decreased coverage rates for search engines.

Purpose: This paper seeks to clarify the research trend of library and information science (US) in Japan from 1970 to 2009.
Methods: Of all the articles published from 1970 to 2009 in Library and Information Science and Journal of Japan Society of Library and Information Science, 826 research articles were examined. For each article, (1) authors, (2) topics, (3) research methods, and (4) the use of theories were analyzed. For (1), the number of authors of each article and the first author's affiliation and occupation were examined. Topics were classified into 14 US topics and these topics were further classified into "library science" and "information science". Empirical research methods were further divided into "data collection method" and "data analysis method". The number of research articles and the transition of the number of pages were also investigated.
Results: Our findings indicate that in the LIS field over the last 40 years in Japan, (1) the number of authors whose affiliation is "university" has increased, (2) the number of "information science" articles has gradually decreased, and the majority of articles are now about "library science", and (3) the proportion of empirical research methods has increased. There were no major changes or distinctive trends in the topics discussed by articles. Due to the adoption of a strict peer-review system in both journals, the number of research articles decreased from the 1990s to 2000s; however, the number of articles has increased in recent years due to the increase in the number of graduate students and the enhancement of research grants in the LIS field.

Purpose: In recent years, the problems of tabloidization of TV news programs and abuse of telops in TV news have grown. Telops in TV news were originally intended to improve understanding of the contents by introducing an information redundancy effect. This study examined by experiment the information redundancy effect of telops when watching TV news.Methods: The experiment included two components: 1) tracking the eye movements of subjects when watching TV news, and 2) examining the degree to which the subjects understood the news contents. As subjects, 22 undergraduate and graduate students participated in the experiment. The participants were divided into two groups: a telop group who watched TV news with telops, and a no-telop group who watched the news without any telops. In the experiment, the differences of eye movements and understanding of the news contents were measured and analyzed.Results: The results from eye movement tracking showed that eye movements in the telop group tended to react sensitively to the appearance of telops. Also, the analysis of understanding showed that the correct answer rates of the telop group were higher than those of the no-telop group for several of the questions. Thus, information redundancy affected the understanding of TV new contents in the experiment. However, telops induced some misunderstanding of some questions.

Eye tracking was used to analyze which elements of which screens were viewed by users searching an Online Public Access Catalog (OPAC). Eye tracking data was obtained for 32 participants performing a known-item search task. The results show that more than 30% of participants did not make effective use of screens offering additional details, and that participants who did, and found the correct answer, gazed at specific screen elements more frequently than participants who gave incorrect answers.

原著論文【目的】近年、情報検索の対象として、「著作」への関心が高まっている。本稿の目的は、日本の図書館目録に現れる著作における著作のつながり、「書誌的家系」の実態を明らかにすることである。【方法】日本の図書館目録に現れる書誌的家系を明らかにするために、J-BISCからの著作の標本を用いた調査を行った。具体的な調査課題として 1) 日本の図書館目録に現れる著作のなかで派生をもつ割合はどれくらいか 2) 書誌的家系の大きさはどれくらいか 3) それぞれの派生の関係種別の出現頻度はどれくらいか 4) 先行研究と比較して日本の図書館目録に現れる書誌的家系に固有の特徴はあるのか、の四つを設定した。 2005年1月までにJ-BISCに収録されたデータを標本の抽出枠として、669件の著作を含んだ標本を構築した。標本に含まれた各著作に対して、NDL-OPACと、Webcat Plusとを用いて、書誌的家系を構成する著作を探索した。また日本の図書館目録に現れる書誌的家系の特徴を明らかにするために、先行研究の結果との比較分析を行った。【結果】調査から、J-BISCに現れる書誌的家系は1) 25.9％に派生著作が存在すること、 2) 平均的な大きさは1.80で、小規模な書誌的家系が多いこと、 3) 派生の関係種別の63.6％が継続派生で単純な家系が多いことがわかった。この調査から、日本の図書館目録においても、書誌的家系のつながりが存在し、それらを図書館目録に導入することの有用性が明らかになった。これまで欧米で行われてきた五つの先行研究との比較から、本調査での結果がこれまでの書誌ユーティリティを用いた調査と同様の傾向を示しており、書誌的家系という著作の現象が、地域や言語に縛られない「普遍性」をもつことが明らかになった。 Library and Information Science No. 61 2009

Purpose: In recent years, “a work” is attracting attention as an entity for information retrieval. This paper investigates associations of works which are called “bibliographic family” represented in the Japanese library catalog.Methods: To investigate bibliographic families in the Japanese library catalog, a survey was conducted using a random sample from J-BISC. Research questions were: 1) what proportion of works in the Japanese library catalog have derivative works, 2) how populous each bibliographic family is, 3) how frequently each type of derivative relationship appears, and 4) whether there are unique characteristics of bibliographic relationships in Japan compared with studies from other countries. From J-BISC, 669 works that had been recorded up to January 2005 were extracted as the sample. To search for members of bibliographic families, NDL-OPAC and Webcat Plus was used. To investigate the characteristics of bibliographic families of works in the Japanese library catalog, the results of previous studies were compared and examined.Results: The survey results show that 1) 25.9% of works in the sample have derivative works, 2) the average size of bibliographic families in the sample is 1.80, and 3) successive relationships account for 63.6% of all types of derivative relationships. Based on these results, networks of bibliographic families really exist, and so it is valid to use the links to improve the library catalog. From a comparison with five previous studies in the U.S. and Slovenia, the phenomenon of works which are called bibliographic families is free from locality and language, and shows “universality.”

This article attempts to characterize "reading (dokusho)" as an action. A large number of studies have focused on one aspect of "reading", such as the reading guidance for students or the reading materials. This research works from a slightly different approach. The focus of this research is what the adult considers "reading" to be. This article regards "reading" as more complex action for the adult. Twenty-nine people were recruited to conduct 5 focus group interviews. The participants were all in their 20s, 30s, and 40s. Focus group sessions allowed for identifying the concept of "reading" for the adult. This paper suggests that reading action was constructed with 5 dimensions. 1) Objects; What they read, 2) Backgrounds and goals; Why and for what they read, 3) Action; How they read, 4) Effects; How they are influenced after reading, 5) Place; Where they read. It must be emphasized that "Objects" could be recognized as more complicated dimensions in this paper. The dimension consisted of following 3 parts; 1) Physical materials, 2) Genres, 3) Values of the contents.

Purpose: The evidence-based librarianship (EBL) approach promotes the application of research results to library services and at the same time, is a promising methodological framework for further improving the quality of research in library science. In this paper, the issues surrounding EBL and its application are discussed.Method: One hundred Japanese journal articles on library and information science were coded according to the level of their EBL evidence (one of seven levels), the three types of EBL questions, and the domain of the article as defined in the EBL approach.Results: Thirty three articles were identified as case studies (Level 6) and fifty three articles were identified as expert opinion (Level 7). Only two articles were coded as summing up (Level 2) which are said to have high EBL evidence. Thirty percent of the papers did not contain questions; therefore, they were not able to be assigned to one of the three types of questions. Fifteen of the articles were in the “collections” domain and twenty three were in the “management” domain; however, no articles were in the “marketing/ promotion” domain. Since the concept of EBL is derived from evidence-based medicine (EBM), it can be difficult to apply it to articles in library and information science.

In machine learning study, we need to prepare test collections for conducting text categorization experiments. However, it has been frequently pointed out that constructing labeled data set is expensive and / or time-consuming. The purpose of this study is automatically identifying and collecting academic articles in Japanese PDF files on the Web. Then, we conducted the automatic detecting experiment using pooling method and compared the performance of various classifiers. Results confirmed applicability and usefulness of pooling method in this experimental environment.

In this paper, we describe methods of classifying Japan MARC records to class number of Nippon Decimal Classification. We compare the performance of three categorization method, based on mutual information (MI), relative frequency and SVM. In each method, training data are title and table of contents and blurb on the flap in Japan MARC records. The experimental results show that the best performance is MI using title and table of contents and blurb on the flap, but other methods are not. In failure analysis, we found the performance depends on subject of class number.
