Abstract

This paper describes a graphical interface for the navigation and construction of faceted thesauri that is based on formal concept analysis. Each facet of a thesaurus is represented as a mathematical lattice that is further subdivided into components. Users can graphically navigate through the Java implementation of the interface by clicking on terms that connect facets and components. Since there are many applications for thesauri in the knowledge representation field, such a graphical interface has the potential of being very useful

Abstract

In this position paper we propose a document-centric middleware component called Living Documents to support context-aware information retrieval in distributed communities. A Living Document acts as a micro server for a document which contains computational services, a semi-structured knowledge repository to uniformly store and access context-related information, and finally the document's digital content. Our initial prototype of Living Documents is based an the concept of mobile agents and implemented in Java and XML.

Abstract

The delivery of documents on the Web has moved beyond the restrictions of the traditional Web markup language, HTML. HTML's static tags cannot deal with the variety of data formats now beginning to be exchanged between various entities, whether corporate or institutional. XML solves many of the problems by allowing arbitrary tags, which describe the content for a particular audience or group. At the Center for Electronic Texts in the Humanities the Latin texts of Lector Longinquus are being transformed to XML in readiness for the expected new standard. To allow existing browsers to render these texts, a Java program is used to transform the XML to HTML on the fly.

Footnote

Rez. in: nfd - Information Wissenschaft und Praxis 54(2003) H.4, S.253 (D. Lewandowski): "Mit "Google Hacks" liegt das bisher umfassendste Werk vor, das sich ausschließlich an den fortgeschrittenen Google-Nutzer wendet. Daher wird man in diesem Buch auch nicht die sonst üblichen Anfänger-Tips finden, die Suchmaschinenbücher und sonstige Anleitungen zur Internet-Recherche für den professionellen Nutzer in der Regel uninteressant machen. Mit Tara Calishain hat sich eine Autorin gefunden, die bereits seit nahezu fünf Jahren einen eigenen Suchmaschinen-Newsletter (www.researchbuzz.com) herausgibt und als Autorin bzw. Co-Autorin einige Bücher zum Thema Recherche verfasst hat. Für die Programmbeispiele im Buch ist Rael Dornfest verantwortlich. Das erste Kapitel ("Searching Google") gibt einen Einblick in erweiterte Suchmöglichkeiten und Spezifika der behandelten Suchmaschine. Dabei wird der Rechercheansatz der Autorin klar: die beste Methode sei es, die Zahl der Treffer selbst so weit einzuschränken, dass eine überschaubare Menge übrig bleibt, die dann tatsächlich gesichtet werden kann. Dazu werden die feldspezifischen Suchmöglichkeiten in Google erläutert, Tips für spezielle Suchen (nach Zeitschriftenarchiven, technischen Definitionen, usw.) gegeben und spezielle Funktionen der Google-Toolbar erklärt. Bei der Lektüre fällt positiv auf, dass auch der erfahrene Google-Nutzer noch Neues erfährt. Einziges Manko in diesem Kapitel ist der fehlende Blick über den Tellerrand: zwar ist es beispielsweise möglich, mit Google eine Datumssuche genauer als durch das in der erweiterten Suche vorgegebene Auswahlfeld einzuschränken; die aufgezeigte Lösung ist jedoch ausgesprochen umständlich und im Recherchealltag nur eingeschränkt zu gebrauchen. Hier fehlt der Hinweis, dass andere Suchmaschinen weit komfortablere Möglichkeiten der Einschränkung bieten. Natürlich handelt es sich bei dem vorliegenden Werk um ein Buch ausschließlich über Google, trotzdem wäre hier auch ein Hinweis auf die Schwächen hilfreich gewesen. In späteren Kapiteln werden durchaus auch alternative Suchmaschinen zur Lösung einzelner Probleme erwähnt. Das zweite Kapitel widmet sich den von Google neben der klassischen Websuche angebotenen Datenbeständen. Dies sind die Verzeichniseinträge, Newsgroups, Bilder, die Nachrichtensuche und die (hierzulande) weniger bekannten Bereichen Catalogs (Suche in gedruckten Versandhauskatalogen), Froogle (eine in diesem Jahr gestartete Shopping-Suchmaschine) und den Google Labs (hier werden von Google entwickelte neue Funktionen zum öffentlichen Test freigegeben). Nachdem die ersten beiden Kapitel sich ausführlich den Angeboten von Google selbst gewidmet haben, beschäftigt sich das Buch ab Kapitel drei mit den Möglichkeiten, die Datenbestände von Google mittels Programmierungen für eigene Zwecke zu nutzen. Dabei werden einerseits bereits im Web vorhandene Programme vorgestellt, andererseits enthält das Buch viele Listings mit Erläuterungen, um eigene Applikationen zu programmieren. Die Schnittstelle zwischen Nutzer und der Google-Datenbank ist das Google-API ("Application Programming Interface"), das es den registrierten Benutzern erlaubt, täglich bis zu 1.00o Anfragen über ein eigenes Suchinterface an Google zu schicken. Die Ergebnisse werden so zurückgegeben, dass sie maschinell weiterverarbeitbar sind. Außerdem kann die Datenbank in umfangreicherer Weise abgefragt werden als bei einem Zugang über die Google-Suchmaske. Da Google im Gegensatz zu anderen Suchmaschinen in seinen Benutzungsbedingungen die maschinelle Abfrage der Datenbank verbietet, ist das API der einzige Weg, eigene Anwendungen auf Google-Basis zu erstellen. Ein eigenes Kapitel beschreibt die Möglichkeiten, das API mittels unterschiedlicher Programmiersprachen wie PHP, Java, Python, usw. zu nutzen. Die Beispiele im Buch sind allerdings alle in Perl geschrieben, so dass es sinnvoll erscheint, für eigene Versuche selbst auch erst einmal in dieser Sprache zu arbeiten.
Das sechste Kapitel enthält 26 Anwendungen des Google-APIs, die teilweise von den Autoren des Buchs selbst entwickelt wurden, teils von anderen Autoren ins Netz gestellt wurden. Als besonders nützliche Anwendungen werden unter anderem der Touchgraph Google Browser zur Visualisierung der Treffer und eine Anwendung, die eine Google-Suche mit Abstandsoperatoren erlaubt, vorgestellt. Auffällig ist hier, dass die interessanteren dieser Applikationen nicht von den Autoren des Buchs programmiert wurden. Diese haben sich eher auf einfachere Anwendungen wie beispielsweise eine Zählung der Treffer nach der Top-Level-Domain beschränkt. Nichtsdestotrotz sind auch diese Anwendungen zum großen Teil nützlich. In einem weiteren Kapitel werden pranks and games ("Streiche und Spiele") vorgestellt, die mit dem Google-API realisiert wurden. Deren Nutzen ist natürlich fragwürdig, der Vollständigkeit halber mögen sie in das Buch gehören. Interessanter wiederum ist das letzte Kapitel: "The Webmaster Side of Google". Hier wird Seitenbetreibern erklärt, wie Google arbeitet, wie man Anzeigen am besten formuliert und schaltet, welche Regeln man beachten sollte, wenn man seine Seiten bei Google plazieren will und letztlich auch, wie man Seiten wieder aus dem Google-Index entfernen kann. Diese Ausführungen sind sehr knapp gehalten und ersetzen daher keine Werke, die sich eingehend mit dem Thema Suchmaschinen-Marketing beschäftigen. Allerdings sind die Ausführungen im Gegensatz zu manch anderen Büchern zum Thema ausgesprochen seriös und versprechen keine Wunder in Bezug auf eine Plazienung der eigenen Seiten im Google-Index. "Google Hacks" ist auch denjenigen zu empfehlen, die sich nicht mit der Programmierung mittels des APIs beschäftigen möchten. Dadurch, dass es die bisher umfangreichste Sammlung von Tips und Techniken für einen gezielteren Umgang mit Google darstellt, ist es für jeden fortgeschrittenen Google-Nutzer geeignet. Zwar mögen einige der Hacks einfach deshalb mit aufgenommen worden sein, damit insgesamt die Zahl von i00 erreicht wird. Andere Tips bringen dafür klar erweiterte Möglichkeiten bei der Recherche. Insofern hilft das Buch auch dabei, die für professionelle Bedürfnisse leider unzureichende Abfragesprache von Google ein wenig auszugleichen." - Bergische Landeszeitung Nr.207 vom 6.9.2003, S.RAS04A/1 (Rundschau am Sonntag: Netzwelt) von P.

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

This article presents an overview of some of the methodology used in a project that examined children's understanding of library information and how those perspectives change in the first 5 years of formal schooling. Because our understanding of information is reflected in the manner in which we classify, or typify, that information in order to view the library collection from a child's perspective children were invited to shelve (i.e., classify) terms representative of library books and then to label those categories. The resulting shelf categories help us to see library information from a child's perspective. Data collection using group dialog, visual imagery, narrative, cooperative learning techniques, and hands-on manipulatives is described for one session of a project in which children used induction to form concepts related to knowledge organization in a hypothetical library. Analysis for this session included use of hierarchical clustering and multidimensional scaling to examine and compare children's constructions for qualitative differences an several grade levels. Following the description of data collection methods and analysis, a discussion focuses an the reasons for using these particular methods of data collection with a child population.

Abstract

This article seeks to address the following questions: Why do certain people, who are fully information literate with printed materials, become hesitant and even reluctant when it comes to finding something on the Internet? And why do we, information professionals, find it difficult to support them adequately? Mature users of digital information are often skeptical about the value of the Internet as a source for professional information. Over the years much has been achieved, but many prophecies of the experts on digitalization from the early hours still have not yet been fulfilled. Mature users do possess all skills needed to be digital-information literate, but they need to be assisted in specific areas where those skills are insufficient. They tend to blame themselves even if shortcomings in accessibility of digital sources and computer errors obstruct their search. Operating hardware requires a dexterity that can only be acquired by experience. Instruction should be hands-on; demonstration is far less effective. Special attention should be given to reading and interpreting navigation information on the screen and to the search strategies the Internet requires. Use of imagination and trial-and-error methods are to be recommended in this respect.

Abstract

Purpose - The purpose of this paper is to report on the content management solution for 50 subject guides maintained by librarian subject specialists at the University of Nevada, Reno Libraries. Design/methodology/approach - The Web Development Librarian designed an SQL Server database to store subject guide content and wrote ASP.Net scripts to generate dynamic web pages. Subject specialists provided input throughout the process. Hands-on workshops were held the summer before the new guides were launched. Findings - The new method has successfully produced consistent but individually customized subject guides while greatly reducing maintenance time. Simple reports reveal the association between guides and licensed resources. Using the system to create course-specific guides would be a useful follow-up project. Skills learned in training workshops should be refreshed at regular intervals to boost confidence and introduce changes in the system. Practical implications - The advantages of centralizing content and separating it from presentation cannot be overstated. More consistency and less maintenance is just the beginning. Once accomplished, a library can incorporate Web 2.0 features into the application by repurposing the data or modifying the ASP.Net template. The now-organized data is clean and ready to migrate to web services or next-generation research guides when the time is right. Originality/value - This paper uniquely reports on an SQL Server, ASP.Net solution for managing subject guides. SQL Server includes data management features that increase application security and ASP.Net offers built-in functionality for manipulating and presenting data. Utmost attention was given to creating simple user interfaces that enable subject specialists to create complex web pages without coding HTML.

Abstract

In the developing world, a common trend is to have north-south collaborations constituting most of the continuous professional development (CPD) activities for librarians. The emerging drift highlighted in this article is a north-south-south initiative aimed at rebuilding the University of Juba Library through capacity-building of the library staff. This article will illuminate the process of equipping library staff with cataloging skills in the absence of previous library training. This endeavor is a result of the collaborative efforts of Makerere University Library (MakLib) in Uganda and the University of Bergen Library (UoBL) in Norway under the Juba Library Automation Project (JULAP). JULAP's main objective is to rebuild the University of Juba Library with the components of library automation and training of library staff. This article will concentrate on the practical training of the library staff in cataloging and the hands-on training on the Koha integrated library system to lay the groundwork for computerized library services for the University of Juba. This article will also highlight the challenges and lessons learned so far while articulating strategies for the future.

Abstract

Although the Internet has become a major source for accessing news, there is little research regarding users' experience with news sites. We conducted an experiment to test a comprehensive model of user experience with news sites that was developed previously by means of an online survey. Level of adoption (novel or adopted site) was controlled with a between-subjects manipulation. We collected participants' answers to psychometric scales at 2 times: after presentation of 5 screenshots of a news site and directly after 10 minutes of hands-on experience with the site. The model was extended with the prediction of users' satisfaction with news sites as a high-level design goal. A psychometric measure of trust in news providers was developed and added to the model to better predict people's intention to use particular news sites. The model presented in this article represents a theoretically founded, empirically tested basis for evaluating news websites, and it holds theoretical relevance to user-experience research in general. Finally, the findings and the model are applied to provide practical guidance in design prioritization.

Abstract

Prelude: Some Science Fiction on the Ultimate Answer and The Ultimate Question Many many millions of years ago a race of hyperintelligent pan-dimensional beings (whose physical manifestation in their own pan-dimensional universe is not dissimilar to our own) got so fed up with the constant bickering about the meaning of life which used to interrupt their favourite pastime of Brockian Ultra Cricket (a curious game which involved suddenly hitting people for no readily apparent reason and then running away) that they decided to sit down and solve their problems once and for all. And to this end they built themselves a stupendous super computer . 'O Deep Thought computer', Fook said, 'the task we have designed you to perform is this. We want you to tell us . ' he paused, 'the Answer!' 'The Answer?' said Deep Thought. 'The Answer to what?' 'Life!' urged Fook. 'The Universe!' said Lunkwill. 'Everything!' they said in chorus. (At this point the whole procedure is interrupted by two representatives of the 'Amalgamated Union of Philosophers, Sages, Luminaries and Other Thinking Persons' who demand to switch off the machine because it endangers their jobs. They demand 'rigidly defined areas of doubt and uncertainty!', and threaten: 'You'll have a national Philosopher's strike on your hands!' . . . )
