6. An Evaluation of a Bibliographic Information Retrieval System Using OPAC Usage Logs

Author

TAKAKU, Masao, OBATA, Masashi, and EGUSA, Yuka

Abstract

図書館資料を対象とした文献検索における適合度順による検索結果ランキングを改善する手法として，OPAC 利用ログを用いた，A）書誌情報の閲覧回数の重み付けによるリランキング手法，B）同一セッション内で使われたクエリキーワードを加味する検索手法の2 つの手法を提案した．筑波大学附属図書館OPAC における約46 ヶ月間にわたるOPAC 利用ログを用いて，提案手法を適用して評価した．評価にあたっては，春日ラーニングコモンズにおける質問事例を参考にした評価用クエリセット16 件を作り，それぞれの手法による検索結果を人手により適合判定して評価した．結果，手法A とB はいずれもベースライン（書誌項目を用いたBM25F ランキング手法）に比べて高い評価が得られ，さらに，手法A よりは手法B のほうが高い評価が得られることが分かった．

Abstract

Obesity is associated with an increased risk of metabolic abnormalities. The citrus fruit calamondin contains nobiletin and hesperidin, which are involved in lipid metabolism, and vitamin C, which is an antioxidant. We investigated the metabolic profiles of C57BL/6 mice fed a normal diet, high-fat diet (HFD), HFD + 1% (w/w) calamondin puree (HFD + CL1), or HFD + 5% (w/w) calamondin puree (HFD + CL5). Glucose tolerance was significantly higher in HFD + CL than in HFD-fed mice. Histological analysis revealed less lipid accumulation in the livers of HFD + CL-fed mice than in those of HFD-fed control mice. Hepatocyte ballooning and large lipid droplets – key non-alcoholic fatty liver disease characteristics – were observed in HFD-fed mice after 4 weeks; however, they were nearly absent in HFD + CL-fed mice. The serum expression level of inflammation-associated Ccl2 was lower in HFD + CL-fed mice than in HFD-fed mice. Thus, calamondin may ameliorate HFD-induced metabolic disturbances, including the progression of non-alcoholic fatty liver disease. [ABSTRACT FROM AUTHOR]

11. A prototype of a loosely coupled cataloging system based on FRBR model

Author

TANABE, Kosuke, TAKAKU, Masao, and EGUSA, Yuka

Abstract

本研究では，FRBR のWork・Expression のエンティティを，既存の運営母体によって作成・管理 された書誌・所蔵データと連動して扱える，疎結合構成の実装モデルを提案する．この提案手法は，Work・Exprsesion の記述のためのシステムを，Web 上で提供されている既存の目録システムと独立して運用することを可能にしている．本研究では既存の目録システムとしてCiNii Books を用いたシステムを試作し，その実現可能性を示した． We propose a loosely coupled implementation model that allows cataloging systems to record FRBR Work and Expression entities connecting bibliographic records maintained by existing libraries. The proposed model enables a cataloging system that records Work and Expression entities to operate in- dependently from existing cataloging systems. We have developed a prototype system that uses CiNii Books as an existing cataloging system and showed its feasibility., 特集 第21回 (2013年度) 年次大会 (研究報告会&総会) ：2013 年 5 月 25 (土) 東京 お茶の水女子大学

12. How Task Types and User Experiences Affect Information-Seeking Behavior on the Web: Using Eye-tracking and Client-side Search Logs

Author

Saito, Hitomi, Terai, Hitoshi, Egusa, Yuka, Takaku, Masao, Miwa, Makiko, Kando, Noriko, Saito, Hitomi, Terai, Hitoshi, Egusa, Yuka, Takaku, Masao, Miwa, Makiko, and Kando, Noriko

Abstract

type:text, We investigated what influence task type and user experience had on information-seeking behaviors on the Web by using screen-capture logs and eye-movement data. Five graduate students in library and information science and eleven undergraduate students with other majors performed two different Web searches, a report-writing and a trip-planning task, and their think-aloud protocols, behaviors, and eye movements were recorded. Analyses of the screen-capture logs and eye-movement data revealed that the task type and user experience affected the participants’ information-seeking behaviors.

Abstract

type:text, We propose new visualization techniques for the user behaviors when using search engine results pages. Our visualization method provides an overview of a user’s actual visual behavior using the logs for eye-movement data and browser link-clicking. We also report on the eye-movement data collected from user experiments.

14. An Application of the NTCIR-WEB Raw-data Archive Dataset for User Experiments

Abstract

type:text, This paper presents a simple approach to utilize past test collections as a material for user experiments. We have built a Web-based user interface for NTCIR-5 WEB run results, and conducted a user experiment with 29 subjects to investigate whether performance evaluation metrics of information retrieval systems used in test collections such as TREC and NTCIR comparable to user performance. In this experiment, we selected three types of systems from among systems that participated in NTCIR-5 WEB, and then selected three topics with roughly the same values from among several search topics. The results of the experiment showed no significant differences among these systems and topics in the time for search. While, in general, the user experiment itself have been successfully conducted and shown similar trends with prior study, the approach seems to have some limitations mainly on interactivity and cached page display.
