Abstract

The paper describes techniques developed by Tome Associates to process natural language queries into search statements suitable for transmission to online text database systems. The problems discussed include word identification, the handling of unknown words, the contents and structure of system dictionaries, the use of semantic categories and classification, disambiguation of multi-meaning words, stemming and truncation, noun compounds and indications of relationship between search terms

Abstract

To meet the demands of academic and intellectual freedom and to encourage students to explore multiple viewpoints on issues, college and university librarians purchase and place denial or revisionist literature in their collections. Identifies current problems in the placement of revisionist and denial literature and proposes a 3-part approach for the handling of these works within a library's collection. Argues in favour of the employment of standards and collaboration between libraries in the classification, cataloguing and placement of such literature

Abstract

Traces the growth of computerized information handling techniques in academic library reference services in the final decades of the 20th Century with particular reference to online databases and the Internet and WWW. Concludes that the pace of change is not likely to decelerate in the foreseeable future and thus the complexity and uncertainty of reference librarianship will increase

Abstract

Nowadays, users of information services are faced with highly decentralised, heterogeneous document sources with different content analysis. Semantic heterogeneity occurs e.g. when resources using different systems for content description are searched using a simple query system. This report describes several approaches of handling semantic heterogeneity used in projects of the German Social Science Information Centre

Abstract

Selecting electronic resources requires both a policy statement to guide collection development and management and procedures to manage the process of selecting and handling these resources. Both policy and procedures must be crafted in response to local priorities, resources, limitations, and organizational structure. This paper examines issues that should be addressed when developing local procedures. Particular emphasis is given to preparing a mechanism to guide selection between various media and modes of information delivery-is explored.

Abstract

Cataloging machine-readable data files (MRDF) is a new challenge to librarians. At the University of Florida, several months were spent on the development of procedures for cataloging computer files. Problems are identified and the University of Florida's solutions to these problems are provided. Our goal was to provide model research library approaches for handling MRDF, specifically magnetic tape computer files.

Abstract

The Resource Description Framework (RDF) is a framework for representing information in the Web. RDF Concepts and Abstract Syntax defines an abstract syntax on which RDF is based, and which serves to link its concrete syntax to its formal semantics. It also includes discussion of design goals, key concepts, datatyping, character normalization and handling of URI references.

Abstract

This book looks at the key skills that are required in organizations in the information intensive society; it also examines the power of information behaviour on the construction of different kinds of shared knowledge and social identity in a group. The book introduces the different dimensions of social capital that is structural and cognitive, and looks at the relational aspects of information behaviour in organizations. This book analyses experiences with two different case studies - in the financial and biotechnology industries - in order to gain additional insights in how the internal organization environment should be designed to support the development of the organization's intellectual capital. Key Features 1. Introduces social capital dimensions to the knowledge management framework 2. Provides empirical work on the new combination of social capital and organizational information behaviour. 3. Two different information sharing practices are presented: a claims handling unit (routine based work) and a biotechnology firm (expert work) 4. Develops social capital measures into qualitative information research 5.The book illustrates the importance of social aspects in ma She has worked as a visiting researcher at Napier University, Edinburgh, 2004-05. Her teaching and research concerns information seeking, information management in business organizations, and aspects of social capital and knowledge sharing in groups and organizations. She has published several articles and papers in these areas. Readership The book is aimed at academics and students at all levels in library and information science, as well as information management and knowledge management practitioners and managers interested in managing information and knowledge effectively.Contents Part 1: Theories of Information Sharing Information sharing in context Patterns of sharing - enablers and barriers Social navigation Part II: Two Practices in Information Sharing Introducing the two cases Claims handlers Expert organisation Part III: Insights into Information, Knowledge Sharing and Social Capital Dimensions of social capital in the two cases Social capital and sharing - building structures for knowledge sharing and its management Importance of the awareness of social capital in connection with information and knowledge sharing in today's companies.

Rez. in: Mitt VÖB 60(2007) H.4, S.95-97 (O. Oberhauser): "Die Autorin ist Dozentin am Institut für Informationswissenschaft der Åbo Akademi University (Finnland) und vertritt zur Zeit den dort vakanten Lehrstuhl. Ihr vorliegendes Buch geht zumindest teilweise auf einen längeren Forschungsaufenthalt an der Napier University, Edinburgh, zurück, wo die informationswissenschaftlich orientierte Forschung am Centre for Social Informatics, welches zum dortigen Fachbereich Informatik zählt, angesiedelt ist. Social informatics (nicht zu verwechseln mit Sozialinformatik, einem Terminus aus dem Gebiet der Sozialen Arbeit), bezieht sich auf die disziplinübergreifende Beschäftigung mit dem Design, dem Einsatz und der Verwendung von Informations- und Kommunikationstechnologien und ihrer Interaktion mit institutionellen und kulturellen Kontexten unter Einschluss von Institutionen/Organisationen und der Gesellschaft. Sie wird von Vertretern verschiedener Wissenschaftsdisziplinen mit unterschiedlichen Themenstellungen bzw. methodischen Ansätzen betrieben. In diesem Umfeld ist auch das vorliegende Buch beheimatet. Zwar ist "information sharing" ein Begriff, der aus der Forschung zu dem breiteren Themenbereich "information seeking and use" bzw. "(human) information behaviour" stammt, doch macht schon der erste Satz des Vorworts klar, dass hier eine thematische Festlegung auf den institutionellen Bereich und damit eine Einordnung in das Gebiet des Wissensmanagements erfolgt ist: "How can organisations correspond to the current demands of effective information and knowledge sharing?" (p. ix). Die Herausforderungen ("challenges") werden im Hinblick auf das Verständnis, die Organisation und die Verwaltung von Wissen gesehen und in technische, betriebliche, persönliche und soziale Aspekte unterteilt. Die Konzentration auf die soziale Dimension, so die Autorin, sei heute besonders wichtig für eine kohärente Beurteilung von Informationsverhalten und -austausch im Unternehmen.
Das Buch gliedert sich in drei Teile. Im ersten Abschnitt, Theories of Information Sharing, erfolgt eine kurze Diskussion von Begriffen und Konzepten aus dem Bereich der kontextuellen Informationssuche, der Information im organisatorischen Umfeld, der Sozial- und Gruppenpsychologie, sowie vor allem die Einführung des Konzeptes "social capital" (soziales Kapital, Sozialkapital), eines aus der Soziologie stammenden theoretischen Ansatzes, als Rahmen für die Betrachtung der Informationsprozesse im Unternehmen. Hier wird Sozialkapital verstanden als die Werte, Normen und Netzwerke, die informationsbezogene Interaktionen möglich und wirksam machen und so die Basis für kollaborative Arbeit zur Verfolgung gemeinsamer Ziele schaffen (p. 30). Der zweite Teil - umfangmässig der größte des Buches - ist mit Two Practices in Information Sharing überschrieben und berichtet detailliert über Fallstudien, die die Autorin in zwei finnischen Unternehmen mittels einer kleinen Zahl qualitativer Interviews durchführte. Dabei wird eine Firma aus der Versicherungsbranche (als einer eher stabilen Branche) mit einem biotechnologischen Produktionsbetrieb (eher turbulent-expansives Umfeld) verglichen. Im dritten Teil, Insights into Information, Knowledge Sharing and Social Capital, diskutiert die Autorin die Resultate ihrer Erhebung, insbesondere im theoretischen Kontext des Sozialkapitals - so etwa die Motive für den Austausch von Informationen und Wissen. Natürlich wird Widén-Wulffs Studie vor allem jene interessieren, die sich mit dem betrieblichen Informations- und Wissensmanagement beschäftigen. Für Interessenten an "information seeking and retrieval" oder "human information behaviour" im Allgemeinen ist das Buch nur bedingt zu empfehlen, doch werden auch sie von den Hinweisen auf den überblicksartig gestreiften Forschungsstand profitieren können. Hingegen werden Rezipienten aus den klassischeren Bereichen des Bibliotheks- bzw. Informationswesens die Lektüre vermutlich als weniger leicht verdaulich empfinden. Der Ladenpreis von mehr als 55 Euro ist für einen Broschurband von knapp 230 Seiten im übrigen viel zu hoch."

Abstract

Many information professionals feel that the time is still far off when the WWW can offer the combined funtionality and content of traditional online and CD-ROM databases, but there have been a number of recent Web developments to reflect on. Describes the testing and launch by Ovid of its Java client which, in effect, allows access to its databases on the Web with full search functionality, and the initiative of Euromonitor in providing Web access to its whole collection of consumer research reports and its entire database of business sources. Also reviews the service of a newcomer to the information scene, Information Quest (IQ) founded by Dawson Holdings which has made an agreement with Infonautics to offer access to its Electric Library database thus adding over 1.000 reference, consumer and business publications to its Web based journal service

Abstract

Examines some of the advanced tools, techniques, methods and standards related to the Internet and WWW which consist of hybrids of documents and software, called 'document program hybrids'. Early Internet systems were based on having documents on one side and software on the other, neatly separated, apart from one another and without much interaction, so that the static document can also exist without computers and networks. Documentation program hybrids blur this classical distinction and all components are integrated, interwoven and exist in synergy with each other. Illustrates the techniques with particular reference to practical examples, including: dara collections and dedicated software; advanced HTML features on the WWW, multimedia viewer and plug in software for Internet and WWW browsers; VRML; interaction through a Web server with other servers and with instruments; adaptive hypertext provided by the server; 'webbots' or 'knowbots' or 'searchbots' or 'metasearch engines' or intelligent software agents; Sun's Java; Microsoft's ActiveX; program scripts for HTML and Web browsers; cookies; and Internet push technology with Webcasting channels

Abstract

A unique collection of historical material covering the lives and events of an English village between 1400 and 1750 has been made available via a WWW enabled information retrieval system. Since the expected readership of the documents ranges from school children to experienced researchers, providing this information in an easily accessible form has offered many challenges requiring tools to aid searching and browsing. The file structure of the document collection was replaced by an database, enabling query results to be presented on the fly. A Java interface displays each user's context in a form that allows for easy and intuitive relevance feedback

Abstract

Presents an approach that integrates searching and browsing in a manner that improves both paradigms. When browsing is the primary task, it enables semantic content-based tailoring of Web maps in both the generation as well as the visualization phases. When search is the primary task, it enables contextualization of the results by augmenting them with the documents' neighbourhoods. This approach is embodied in WebCutter, a client-server system fully integrated with Web software. WebCutter consists of a map generator running off a standard Web server and a map visualization client implemented as a Java applet runalble from any standard Web browser and requiring no installation or external plug-in application. WebCutter is in beta stage and is in the process of being integrated into the Lotus Domino application product line

Abstract

The KMODDL (kinematic models for design digital library) is a digital library based on a historical collection of kinematic models made of steel and bronze. The digital library contains four types of learning modules including textual materials, QuickTime virtual reality movies, Java simulations, and stereolithographic files of the physical models. The authors report an evaluation study on the uses of the KMODDL in two undergraduate classes. This research reveals that the users in different classes encountered different usability problems, and reported quantitatively different subjective experiences. Further, the results indicate that depending on the subject area, the two user groups preferred different types of learning modules, resulting in different uses of the available materials and different learning outcomes. These findings are discussed in terms of their implications for future digital library design.

Abstract

The Indiana University School of Library and Information Science opened a new research laboratory in January 2003; The Indiana University School of Library and Information Science Information Processing Laboratory [IU IP Lab]. The purpose of the new laboratory is to facilitate collaboration between scientists in the department in the areas of information retrieval (IR) and information visualization (IV) research. The lab has several areas of focus. These include grid and cluster computing, and a standard Java-based software platform to support plug and play research datasets, a selection of standard IR modules and standard IV algorithms. Future development includes software to enable researchers to contribute datasets, IR algorithms, and visualization algorithms into the standard environment. We decided early on to use OAI-PMH as a resource discovery tool because it is consistent with our mission.

Abstract

It is widely believed that many queries submitted to search engines are inherently ambiguous (e.g., java and apple). However, few studies have tried to classify queries based on ambiguity and to answer "what the proportion of ambiguous queries is". This paper deals with these issues. First, we clarify the definition of ambiguous queries by constructing the taxonomy of queries from being ambiguous to specific. Second, we ask human annotators to manually classify queries. From manually labeled results, we observe that query ambiguity is to some extent predictable. Third, we propose a supervised learning approach to automatically identify ambiguous queries. Experimental results show that we can correctly identify 87% of labeled queries with the approach. Finally, by using our approach, we estimate that about 16% of queries in a real search log are ambiguous.

Abstract

Medical insurance fraud is common in many countries' medical insurance systems and represents a serious threat to the insurance funds and the benefits of patients. In this paper, we present an inference model of medical insurance fraud detection, based on a medical detection domain ontology that incorporates the knowledge base provided by the Medical Terminology, NKIMed, and Chinese Library Classification systems. Through analyzing the behaviors of irregular and fraudulent medical services, we defined the scope of the medical domain ontology relevant to the task and built the ontology about medical sciences and medical service behaviors. The ontology then utilizes Semantic Web Rule Language (SWRL) and Java Expert System Shell (JESS) to detect medical irregularities and mine implicit knowledge. The system can be used to improve the management of medical insurance risks.

Abstract

When we first began discussing with Peter Paulson, executive director of OCLC Forest Press, the possibility of translating into Spanish the twentieth edition of the Dewey Decimal Classification, and even during the initial contact we had with the late John A. Humphry, we knew that the project would be a complex and hard task. The reality was that the project exceeded all expectations and was much more complex and difficult than we had anticipated. This not only made it more interesting for those who participated in its development, but also made it an extraordinary challenge, especially due to the time frame initially foreseen for its development: eight to ten months. Once we agreed with Peter Paulson on the basic terms of the project, Rojas Eberhard Editores was able to convince Information Handling Services (a company located in Denver, Colorado, known worldwide for its products and services in the field of technological information) to participate with us in this translation and publication project. Information Handling Services channeled its participation through its subsidiary in Mexico, to facilitate the integration of the project into the main zone of influence of the final product: Latin America.
