Abstract

This paper analyzes proposals for augmenting library bibliographic records for improved subject searching in online catalogs. Possible fields for enrichment are described and their likely value assessed. The assessment determines that the main value of enriched records would be to provide access to parts of books. The paper presents arguments for and against adding book content indexing to the online catalog and analyzes the feasibility of eleven alternatives for providing such information

Abstract

As librarians plan ahead to make subject enhancements available to online searchers in various possible file locations and formats, they may want to base their decisions on implications for online searching. This paper explores some of these implications with respect to unique and misleading terminology in tables of contents, Choice abstracts, and reviews from Computing reviews for thirty-six books on information and computer science chosen from the 1987 issues of Choice. It also discusses possible interacting functions in the search process served by these subject enhancements, assigned LCSH, and book title terminology

"AGI - Information Management Consultants (www.agi-imc.de) hatte am 8. und 9. Mai 2007 zum vierten Mal Bibliotheken und Partner zum Erfahrungsaustausch nach Neustadt an der Weinstraße eingeladen. Die angereisten Teilnehmer betreiben bereits mittels intelligentCAPTURE die Produktion und über dandelon.com den Austausch und die Publikation (www.dandelon.com). Mittlerweile wird intelligentCAPTURE in Deutschland, Österreich, Liechtenstein, Italien und in der Schweiz eingesetzt. Die PDF-Dateien gelangen über einen Partner bis zur weltgrößten Bibliothek, der Library of Congress in Washington. In Deutschland ist der GBV - Gemeinsamer Bibliotheksverband in Göttingen (www.gbv.de) Partner von AGI und der größte Sekundärnutzer von dandelon.com. In dandelon.com sind derzeit über 220.000 Bücher suchbar, die Datenbank wächst täglich. Weitere 62.000 Titel werden nach einem Software-Update demnächst geladen; sie stammen aus Projekten mit der Staats-und Universitätsbibliothek Hamburg und der TIB Hannover. Vergleichbare Scanprojekte laufen derzeit in einer Spezialbibliothek in Hamburg, der UB Braunschweig und UB Mainz. AGI geht von 400 bis 500.000 Buchtiteln bis Ende 2007 aus. Erstmals sahen die Teilnehmer "intelligentCAPTURE mobile". Eine Lösung, welche die Scanner selbst zwischen die engsten Regale fährt und somit erheblich den Transportaufwand reduziert - der Scanner wird zum Buch transportiert, nicht Tonnen von Büchern zu Scannern. Gemeinsam mit dem führenden Anbieter von Bibliothekseinrichtungen Schulz Speyer (www.schulzspeyer.de) wurde intelligentCAPTURE mobil gemacht.
Bis zu 530 Bücherinhaltsverzeichnisse wurden bisher von einer Person an einem Tag damit produziert. Rund 1.000 Bücher pro Tag ist die durchschnittliche Menge bei einem Scanteam mit drei Scanstationen. Digitalisiert wird immer nur der urheberrechtsfreie bzw. durch Lizenzierung zulässige Bereich. Neben Büchern werden auch Zeitschriften ausgewertet. So sind z.B. die Aufsätze aus der Zeitschrift "IWP - Information. Wissenschaft und Praxis" der Deutschen Gesellschaft für Informationswissenschaft und Informationspraxis (http://www.dgi-info.de) komplett digital - und einige auch mit MP3Hördateien ergänzt. Anwendung finden seit 2006 die Lösungen von AGI auch in der Suche von Parlamentsmaterialien, also in der öffentlichen Verwaltung - konkret dem wirtschaftlich erfolgreichsten Bundesland Österreichs, Vorarlberg. Diese Leistung wird als Dienstleistung der Vorarlberger Landesbibliothek (http://vlb-katalog.vorarlberg.de) erbracht (www.vorarlberg.at/landtag/landtag/parlamentarischematerialien/recherche.htm)
Das Highlight unter den Referaten bei dieser Tagung waren die Ausführungen des Vordenkers Andreas Prokoph, Lead Architect - Search Technologies and Portal Server Development, vom deutschen IBM Entwicklungslabor. Er sprach über Information Retrieval. Mit über 200 Patenten, darunter auch seinen eigenen, liegt IBM in diesem Forschungsfeld weit vorne. Die IBM Suchmaschine OMNIFIND soll möglichst bald die Suchtechnik hinter dandelon.com ersetzen und den Suchraum auf Kataloge, Open Archives, Verlage, Hochschul-Server ausdehnen. Schon heute basieren intelligentCAPTURE und dandelon.com weitgehend auf IBM-Technologien, konkret Lotus Notes & Domino und Lotus Sametime (www.ibm.corn/ lotus/hannover), aber auch auf integrierten Modulen anderer international führender Technologiespezialisten."

Abstract

Experimental evidence suggests that enhancing the subject content of OPAC records can improve retrieval performance. This is based on the use of natural language index terms derived from the table of contents and back-of-the-book index of documents. The research reported here investigates the alternative approach of translating these natural language terms into controlled vocabulary. Subject queries were collected by interview at the catalogue, and indexing of the queries demonstrated the impressive ability of PRECIS, and to a lesser extent LCSH, to represent users' information needs. DDC performed poorly in this respect. The assumption was made that an index language adequately specific to represent users' queries should be adequate to represent document contents. Searches were carried out on three test databases, and both natural language and PRECIS enhancement of MARC records increased the number of relevant documents found, with PRECIS showing the better performance. However, with weak stemming the advantage of PRECIS was lost. Consideration must also be given to the potential advantages of controlled vocabulary, over and above basic retrieval performance measures

Abstract

The author collected information about tables of content and index terms in 125 books borrowed by patrons in a medium-sized academic library. To learn how useful the term would be as subject terms in a library catalog, he determined which of these terms were the same as the words used by the patrons to describe the books. For 72,4% of the books assigned LCSH, the patron's term matched the LCheading. The patron's term matched the table of contents term for (1,3% of the books with tables of contents. If the catalog had included terms from the tables of contents and the indexes in addition to the LCSH, the success rate would have been 97,3%. One problem in using terms from books in a library catalog is that many books lack indexes and/or tables of context

Abstract

Describes the Intelligent Literature Search Assistant (ILSA) which demonstrates the possibilities of a fully automated cataloguing workbench in an object orientated environment. Although developed with OPAC users in mind, it can be very useful to cataloguers in aiding both classification and subject heading access. Also describes work done at the University of Strathclyde in the area of machine learning and knowledge based systems, the Structured Information Management: Processing and Retrieval project (SIMPR). Advocates the use of uncontrolled vocabulary headings in conjunction with systems like ILSA, a layered approach rather than direct first point access, in order to make subject cataloguing easier and more relevant and the subject catalogue more useful to others
