- Abstract
- Die K3-Architektur zur technischen Entwicklung und Realisierung des netzbasierten Wissensmanagement in der Lehre wird dargestellt. Das aktuelle K3-System besteht aus drei zentralen Komponenten; K3Forum (Diskurs), K3Vis (Visualisierung) und K3Wiki (kollaborative Textproduktion, z. B. für Zusammenfassungen). K3 verwendet Open-Source-Software unter der LGPL Lizenz.. Dadurch können freie Verwendung, überschaubare Entwicklungskosten und Nachhaltigkeit garantiert und die Unabhängigkeit von kommerziellen Software-Anbietern gesichert werden. Dank des komponentenbasierten Entwicklungskonzepts kann K3 flexibel und robust laufend weiterentwickelt werden, ohne die Stabilität der bestehenden Funktionalitäten zu beeinträchtigen. Der Artikel dokumentiert exemplarisch die Hauptkomponenten und Funktionen von K3, so dass nachfolgende Entwickler leicht eine Übersicht über das K3-System gewinnen können. Die Anforderungen an den Transfer des Systems in Umgebungen außerhalb von Konstanz werden beschrieben.

- Abstract
- This review of 2004 and 2005 serials literature covers the themes of cost, management, and access. Interwoven through the serials literature of these two years are the importance of collaboration, communication, and linkages between scholars, publishers, subscription agents and other intermediaries, and librarians. The emphasis in the literature is on electronic serials and their impact on publishing, libraries, and vendors. In response to the crisis of escalating journal prices and libraries' dissatisfaction with the Big Deal licensing agreements, Open Access journals and publishing models were promoted. Libraries subscribed to or licensed increasing numbers of electronic serials. As a result, libraries sought ways to better manage licensing and subscription data (not handled by traditional integrated library systems) by implementing electronic resources management systems. In order to provide users with better, faster, and more current information on and access to electronic serials, libraries implemented tools and services to provide A-Z title lists, title by title coverage data, MARC records, and OpenURL link resolvers.

- Abstract
- The Specialized Information Services Division (SIS) of the National Library of Medicine (NLM) provides Web access to more than a dozen scientific databases on toxicology and the environment on TOXNET . Search queries on TOXNET often include misspelled or variant English words, medical and scientific jargon and chemical names. Following the example of search engines like Google and ClinicalTrials.gov, we set out to develop a spelling "suggestion" system for increased recall and precision in TOXNET searching. This paper describes development of dictionary technology that can be used in a variety of applications such as orthographic verification, writing aid, natural language processing, and information storage and retrieval. The design of the technology allows building complex applications using the components developed in the earlier phases of the work in a modular fashion without extensive rewriting of computer code. Since many of the potential applications envisioned for this work have on-line or web-based interfaces, the dictionaries and other computer components must have fast response, and must be adaptable to open-ended database vocabularies, including chemical nomenclature. The dictionary vocabulary for this work was derived from SIS and other databases and specialized resources, such as NLM's Unified Medical Language Systems (UMLS) . The resulting technology, A-Z Dictionary (AZdict), has three major constituents: 1) the vocabulary list, 2) the word attributes that define part of speech and morphological relationships between words in the list, and 3) a set of programs that implements the retrieval of words and their attributes, and determines similarity between words (ChemSpell). These three components can be used in various applications such as spelling verification, spelling aid, part-of-speech tagging, paraphrasing, and many other natural language processing functions.
