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

Bibliographic family in Japanese library catalog

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.”

Dimensions of Reading : Findings from a Focus Group Interview to Adults

KUNIMOTO Chihiro, MIYATA Yosuke, KOIZUMI Masanori, KINJO Yuna, UEDA Shuichi

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.

Re-examination of evidence-based librarianship (EBL)

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.
