- Abstract
- Moderne Verfahren des Information Retrieval verlangen nach aussagekräftigen und detailliert relationierten Dokumentationssprachen. Der selektive Transfer einzelner Modellierungsstrategien aus dem Bereich semantischer Technologien für die Gestaltung und Relationierung bestehender Dokumentationssprachen wird diskutiert. In Form einer Taxonomie wird ein hierarchisch strukturiertes Relationeninventar definiert, welches sowohl hinreichend allgemeine als auch zahlreiche spezifische Relationstypen enthält, die eine detaillierte und damit aussagekräftige Relationierung des Vokabulars ermöglichen. Das bringt einen Zugewinn an Übersichtlichkeit und Funktionalität. Im Gegensatz zu anderen Ansätzen und Überlegungen zur Schaffung von Relationeninventaren entwickelt der vorgestellte Vorschlag das Relationeninventar aus der Begriffsmenge eines bestehenden Gegenstandsbereichs heraus.

- Abstract
- When consumers search for health information, a major obstacle is their unfamiliarity with the medical terminology. Even though medical thesauri such as the Medical Subject Headings (MeSH) and related tools (e.g., the MeSH Browser) were created to help consumers find medical term definitions, the lack of direct and explicit integration of these help tools into a health retrieval system prevented them from effectively achieving their objectives. To explore this issue, we conducted an empirical study with two systems: One is a simple interface system supporting query-based searching; the other is an augmented system with two new components supporting MeSH term searching and MeSH tree browsing. A total of 45 subjects were recruited to participate in the study. The results indicated that the augmented system is more effective than the simple system in terms of improving user-perceived topic familiarity and question-answer performance, even though we did not find users spend more time on the augmented system. The two new MeSH help components played a critical role in participants' health information retrieval and were found to allow them to develop new search strategies. The findings of the study enhanced our understanding of consumers' search behaviors and shed light on the design of future health information retrieval systems.

- Abstract
- Despite early claims to the contemporary, thesauri continue to find use as access tools for information in the full-text environment. Their mode of use is changing, but this change actually represents an expansion rather than a contrdiction of their utility. Thesauri and similar vocabulary tools can complement full-text access by aiding users in focusing their searches, by supplementing the linguistic analysis of the text search engine, and even by serving as one of the tools used by the linguistic engine for its analysis. While human indexing contunues to be used for many databases, the trend is to increase the use of machine aids for this purpose. All machine-aided indexing (MAI) systems rely on thesauri as the basis for term selection. In the 21st century, the balance of effort between human and machine will change at both input and output, but thesauri will continue to play an important role for the foreseeable future

- Abstract
- In principle, the 'knowledge' encoded in a thesaurus can be exploited in many ways to help users clarify their information needs and enhance query performance, but attempts to automate this process via AI techniques face many practical difficulties. In the short term it may be more useful to improve support for direct interactive use of thesauri. We discuss some of the issues which have arisen when building an interface for thesaurus navigation and query enhancement, drawing on logs and user feedback from ongoing small-scale experiments

- Abstract
- Because the multilingual thesaurus has a critical role to play in the global networked information world, its relational structure must come under close scrutiny. Traditionally, identity of relational structures has been sought for the different language versions of a multilingual thesaurus, often leading to the artificialization of all target languages. The various types of cross-lingual and intralingual relations found in thesauri are examined in the context of two questions: Are all types of thesaural relations transferable from one language to another? and Are the two members of a valid relation in a source language always the same in the target language(s)? Two options for resolving semantic conflicts in multilingual thesauri are presented.

- Abstract
- A thesaurus and an ontology provide a set of structured terms, phrases, and metadata, often in a hierarchical arrangement, that may be used to index, search, and mine documents. We describe the decisions that should be made when including a term, deciding whether a term should be subdivided into its subclasses, or determining which of more than one set of possible subclasses should be used. Based on retrospective measurements or estimates of future performance when using thesaurus terms in document ordering, decisions are made so as to maximize performance. These decisions may be used in the automatic construction of a thesaurus. The evaluation of an existing thesaurus is described, consistent with the decision criteria developed here. These kinds of user-focused decision-theoretic techniques may be applied to other hierarchical applications, such as faceted classification systems used in information architecture or the use of hierarchical terms in "breadcrumb navigation".

- Abstract
- For the sake of national security, very large volumes of data and information are generated and gathered daily. Much of this data and information is written in different languages, stored in different locations, and may be seemingly unconnected. Crosslingual semantic interoperability is a major challenge to generate an overview of this disparate data and information so that it can be analyzed, shared, searched, and summarized. The recent terrorist attacks and the tragic events of September 11, 2001 have prompted increased attention an national security and criminal analysis. Many Asian countries and cities, such as Japan, Taiwan, and Singapore, have been advised that they may become the next targets of terrorist attacks. Semantic interoperability has been a focus in digital library research. Traditional information retrieval (IR) approaches normally require a document to share some common keywords with the query. Generating the associations for the related terms between the two term spaces of users and documents is an important issue. The problem can be viewed as the creation of a thesaurus. Apart from this, terrorists and criminals may communicate through letters, e-mails, and faxes in languages other than English. The translation ambiguity significantly exacerbates the retrieval problem. The problem is expanded to crosslingual semantic interoperability. In this paper, we focus an the English/Chinese crosslingual semantic interoperability problem. However, the developed techniques are not limited to English and Chinese languages but can be applied to many other languages. English and Chinese are popular languages in the Asian region. Much information about national security or crime is communicated in these languages. An efficient automatically generated thesaurus between these languages is important to crosslingual information retrieval between English and Chinese languages. To facilitate crosslingual information retrieval, a corpus-based approach uses the term co-occurrence statistics in parallel or comparable corpora to construct a statistical translation model to cross the language boundary. In this paper, the text based approach to align English/Chinese Hong Kong Police press release documents from the Web is first presented. We also introduce an algorithmic approach to generate a robust knowledge base based an statistical correlation analysis of the semantics (knowledge) embedded in the bilingual press release corpus. The research output consisted of a thesaurus-like, semantic network knowledge base, which can aid in semanticsbased crosslingual information management and retrieval.

- Abstract
- Presents a state of the art review of the literature of expert systems in library and information science, involving exhaustive searches of all major LIS CD-ROM databases (LISA, ERIC, LiLi, INSPEC etc.) and bibliographies appended in review articles. The search retrieved 679 references, comprising 362 periodical articles, 180 conference proceedings, 63 books articles, 28 theses and 46 monographs. The growth of the literature peaked between 1989 and 1990 and subsequently declined after 1992. Over 1/3 (287) covered intelligent front ends and interfaces for online searching and retrieval, followed by applications in reference service (113), classification, indexing and abstracting (86) and cataloguing (7). The most productive periodicals comprised 6 titles, of which 'Information processing and management' topped the lsit: 43 authors were found to contribute between 5 and 35 articles each, hence contributing 32,19% of the total contributors. 382 of the publications were single author works, 172 were by 2 authors, 72 were by 3 authors and 49 were by 4 or more authors. Only 161 titles were expressive enough to reveal both the name and function of systems being developed

- Abstract
- Some of the fundamental activities of the software development process are related to the discipline of Requirements Engineering, whose objective is the discovery, analysis, documentation and verification of the requirements that will be part of the system. Requirements are the conditions or capabilities that software must have or perform to meet the users needs. The present study is being developed to propose a model of cooperation between Information Science and Requirements Engineering. Aims to present the analysis results on the possibilities of using the knowledge organization systems: taxonomies, thesauri and ontologies during the activities of Requirements Engineering: design, survey, elaboration, negotiation, specification, validation and requirements management. From the results obtained it was possible to identify in which stage of the Requirements Engineering process, each type of knowledge organization system could be used. We expect that this study put in evidence the need for new researchs and proposals to strengt the exchange between Information Science, as a science that has information as object of study, and the Requirements Engineering which has in the information the raw material to identify the informational needs of software users.

- Abstract
- This article describes the process of constructing a thesaurus based on original historical documents located in the Archivo del Reino de Valencia, one of the most important historical archives in Spain. After examining precedents, we discuss the methodology used and its application. The aim of the project was to provide visibility to information contained in these historical documents which would otherwise have remained inaccessible and to do so in the clearest, most rigorous, and most useful way possible for both the specialized user and the general public. The use of information technology as a management tool is not as common in archives, especially historical archives, as in other documentation areas such as libraries. A pilot project was therefore set up to create an intranet support for managing four specific historical archives containing documents dating from the 13th to the 20th centuries. The most important part of this project was that of exploring the viability of constructing a thesaurus to become part of the automated program for archive description and checking.

- Abstract
- Shows the possibilities that exist to create a basic hypertext interface for a thesaurus management system. The project has been built in 3 stages: conceptual data model for the thesaurus; development of the management tools, that is, the thesaurus management system; and the hypertext interfaces. The system has been developed on Windows and combines the power of relational database management systems and the navigational flexibility of Guide, a hypertext shell. presents 2 interface models. Concludes that hypertext interfaces improve management, and open a new path for knowledge organization research

- Abstract
- Der Thesaurus als Dokumentationssprache wird in der DIN 1463-1in seinen wesentlichen Merkmalen beschrieben. Dort wird der Thesaurus im informationswissenschaftlichen Sinne so definiert: "Ein Thesaurus im Bereich der Information und Dokumentation ist eine geordnete Zusammenstellung von Begriffen und ihren (vorwiegend natürlichsprachigen) Bezeichnungen, die in einem Dokumentationsgebiet zum Indexieren, Speichern und Wiederauffinden dient. Er ist durch folgende Merkmale gekennzeichnet: a) Begriffe und Bezeichnungen werden eindeutig aufeinander bezogen ("terminologische Kontrolle"), indem - Synonyme möglichst vollständig erfasst werden, - Homonyme und Polyseme besonders gekennzeichnet werden, - für jeden Begriff eine Bezeichnung (Vorzugsbenennung, Begriffsnummer oder Notation) festgelegt wird, die den Begriff eindeutig vertritt, b) Beziehungen zwischen Begriffen (repräsentiert durch ihre Bezeichnungen) werden dargestellt." Diese Definition wäre zu ergänzen um folgende: c) Der Thesaurus ist präskriptiv, indem er für seinen Geltungsbereich festlegt, welche begrifflichen Einheiten zur Verfügung gestellt werden und durch welche Bezeichnungen diese repräsentiert werden. Im Folgenden sollen die wichtigsten Elemente und Prinzipien von Thesauri und die Thesaurusmethodik vorgestellt werden. Dies kann in diesem Rahmen nur auf eine sehr kursorische und allgemeine Art und Weise geschehen. Außerdem beschränkt sich die Darstellung auf den Thesauruseinsatz im klassischen Bereich von Information und Dokumentation. Auf die Behandlung von Spezialproblemen oder auf besondere Thesaurusformen (z.B. mehrsprachige Thesauri) kann hier nicht eingegangen werden, ebenso auf die erweiterten Anforderungen, die an Thesauri im Kontext von Wissensrepräsentation oder Hypertext zu stellen sind. Allerdings überschneidet sich der klassische IuD-Bereich zunehmend mit erweiterten Formen (etwa im Rahmen von Internetanwendungen). Da der Thesaurus im dokumentarischen Sinn alle Grundelemente des Thesaurusprinzips in klarer Form aufweist, wird dieser Bereich für eine Einführung gewählt. Für eine intensivere Auseinandersetzung mit der Thematik wird die Lektüre von Wersig empfohlen, auf den sich auch die folgenden Ausführungen in weiten Teilen stützen. Eine weitere grundsätzliche Einführung in diesen Bereich, allerdings eher ausgerichtet auf die Spezifika des englischen Sprachraums, findet sich bei Lancaster.
