摘要

圖書館的「線上公用目錄」(On-Line Public Access Catalog, OPAC)系統,是提供讀者查詢圖書館館藏資料的重要工具,也是早期資訊檢索技術主要的應用方向。本文即以輔仁大學圖書館為例,說明整合新一代資訊檢索技術於 OPAC 系統的實施現況。我們運用非營利機構可獲得的先進檢索引擎,輔以自行發展的關鍵詞擷取技術,完成具備重要性排序、近似字串、模糊搜尋、相關詞回饋、允許近似自然語言檢索字串的 OPAC 系統。初步的評估發現,這樣的系統對協助使用者簡化查詢條件、拓展檢索字彙、提昇檢索成效有相當的助益。

Title Advanced Information Retrieval Technology for Online Public Access Catalog System
Author Yuen-Hsien Tseng
Author's title Associate Professor, Department of Library & Information Science, Fu Jen Catholic University
Abstract

The On-Line Public Access Catalog (OPAC) system is an important tool in helping users to retrieve information from a large volume of data stored in a library. However, recent advances in information retrieval technologies have not yet been applied to most OPAC systems. This paper introduces the development of a novel OPAC system which applies a free advanced search engine available from the Internet and an automatic keyword extraction function developed by the Department of Library and Information Science. The resultant features of the OPAC system include relevance ranking, fuzzy search, relevance feedback, and query by quasi-natural language. Results show that such a system greatly simplifies query formulations and automatically prompts more relevant search vocabulary to the users, thus improving the performance of an OPAC system to a higher degree.

摘要

圖書館的館藏目錄是使用者開啟館藏之鑰,可以協助使用者了解館藏的出處、辨識和選擇不同的版本。圖書館館藏目錄使用研究,則有助於瞭解使用者使用的檢索點、使用的檢索技巧,如提供關鍵字和布林邏輯檢索、限制檢索(如切截等)、使用時遇到的困難,或者進一步分析使用者使用的檢索詞彙等。這些瞭解,不僅有助於圖書館對使用者資訊尋求行為的掌握,並可做為改善系統設計之參考。本文以1985年至1999年,近十五年的英文文獻為探討的對象,分析線上目錄使用者使用的檢索點、檢索失敗的原因、使用的檢索策略、使用者對改善線上目錄的看法、線上公用目錄使用者教育等問題。

Title The Use Studies of Online Public Access Catalog: A Literature Review
Author Nei-ching Yeh
Author's title Department of Library and Information Studies, Shih Hsin University
Abstract

The Online Public Access Catalog (OPAC) is the best gateway for users to get access to library collections and to locate library materials. Through the use studies of OPAC, libraries can understand the information seeking behavior of its users, and can improve on their own design of OPAC system. This paper reviews the related OPAC research literatures in English in the past 15 years (1985-1999), analyzed the users’ problems of access points, search terms, search strategies, and other related issues on training users.

摘要

本研究主要探討OPAC文獻之基本特性,如:文獻成長情形及出版品類型、語言、作者與期刊之分佈情形,並以書目計量學之洛卡定律和布萊德福定律,加以驗證著者生產力與期刊文獻之分佈。研究結果發現1975至2000年間,OPAC文獻仍持續的成長,呈現邏輯斯第曲線的成長模式;文獻發表的語言以英語最為普遍,並且以強調新穎性的期刊類型為主要出版品;出版一篇文獻的作者佔77.82%;利用布萊德福定律求出八種核心期刊。在文獻作者生產力與期刊文獻分佈方面符合洛卡定律與布萊德福定律之結果。

Title A Bibliometric Study of Online Public Access Catalog Literature
Author Ming-yueh Tsay; Shih-fang Hung
Author's title Department of Information and Library Science, Tamkang University
Abstract

On the basis of bibliometric analysis, this study explores the characteristics of the OPAC literature, such as the literature growth, document type, language, author productivity and the distribution of journal articles. The OPAC literature, 1975-2000, shows an example of logistic growth. English is the predominant language and the most popular form of publication is the journal article. The vast majority of authors, (77.82%), publish one article only in the subject of OPAC. English core journals were identified based on Bradford’s law. The results of the present study also revealed that author and journal productivity were consistent with Lotka's law and Bradford's law.

摘要

本研究提出一個適用於CMARC4完整版之XML DTD,並透過系統實作方式,架構一個基於XML之編目、WebOPAC及WAPOPAC模組。本文主要研究成果如下:首先,我們探討CMARC4完整版之DTD在設計時比簡篇更複雜的議題,並提出一個實驗用途但內容完整的版本,可做為相關單位制訂標準時之參考依據;其次,本文透過XML與XSL的相互搭配,可使WebOPAC的檢索結果呈現不同版面格式,而又不影響原始資料結構;再者,我們結合WAP技術,發展一個名為WAPOPAC(WAP-based OPAC)的行動線上公用目錄系統,可透過WAP終端設備來連線,以滿足行動圖書館的通訊需求!

Title Design Cataloguing Module and WebOPAC/WACOPAC Based on XML and CMARC
Author Sinn-cheng Lin; Hsiang-tsun Yang
Author's title (Department of Information and Library Science, Tamkang University; Graduate Student,Department of Information and Library Science, Tamkang University
Abstract

This paper proposes an appropriate DTD for CMARC4, and implements three modules based on XML technology: a cataloguing module, a WebOPAC module and a WAPOPAC module. The research results are as follows: First, we examine some complicated issues of CMARC DTD design. An experimental but complete version involved in CMARC DTD is proposed for reference. Secondary, we combine XML with XSL for WebOPAC to show the query results in a different layout format without affecting the original data structure. Furthermore, we apply the WAP technology to develop an online public catalogue system for mobile access. Which is named WAPOPAC(WAP-based OPAC). The users could use WAP devices to access such a WAP-based mobile library.
