During the current period of rapid technological change, business students need to emerge from their introductory course in Information Systems (IS) with a set of fundamental principles to help them "think about Information Technology (IT)" in future courses and the workplace. Given the digital revolution, they also need to appreciate…

The paper describes the concept of a federated ecosystem for Open Educational Resources (OER) in the German education system. Here, a variety of OER repositories (ROER) (Muuß-Merholz & Schaumburg, 2014) and reference platforms have been established in the recent past. In order to develop this ecosystem, not only are metadata standards…

This lab exercise exposes students to Evernote, which is a powerful productivity application that has gained significant purchase in professional work environments. In many academic settings the introductory computer applications course has a specific focus on standard productivity applications such as MS Word and MS Excel. While ensuring fluency…

In this paper, a client/server information system for the management of data and its extraction from a database containing information for diploma works of students is proposed. The developed system provides users the possibility of accessing information about different characteristics of the diploma works, according to their specific interests.…

Even though the concept of information literacy typically embraces an idea of a complete participation in an information community, its definitions have tended to underline the phases of seeking, searching and evaluation instead of creating information. Shortcomings of information creation can, however, explain many of the difficulties of finding…

This paper describes the use and benefits of Microsoft's Adventure Works (AW) database to teach advanced database skills in a hands-on, realistic environment. Database management and querying skills are a key element of a robust information systems curriculum, and active learning is an important way to develop these skills. To facilitate active…

Competency education is student-centric, personalizing student progress so that every child has adequate time and support to reach proficiency every step of the way. Competency education fundamentally changes the way the educational enterprise is organized around student needs, and thus must have a dynamic IT system to support it. Following an…

Discussion of information retrieval and relevance focuses on mutual information, a measure which represents the relation between two words. A model of a natural-language information-retrieval system that is based on a two-level document-ranking method using mutual information is presented, and a Korean encyclopedia test collection is explained.…

Introduces navigation as a central concept for information retrieval and for information systems in general. The evolution of information systems is described; navigability as an aid to improve relevance is discussed; and a system under development that attempts to facilitate navigation for information retrieval is described.

Describes a scalable, parallel, relational database-drive information retrieval engine. To support portability across a wide range of execution environments, all algorithms adhere to the SQL-92 standard. By incorporating relevance feedback algorithms, accuracy is enhanced over prior database-driven information retrieval efforts. Presents…

Discussion of database design that allows wider range of capabilities than conventional information retrieval database covers prestructuring of searches to pinpoint target items, which are selected from browseable display, and navigation capability, which allows user to move from record to record within database to facilitate extraction of…

With the number and types of documents in digital library systems increasing, tools for automatically organizing and presenting the content have to be found. While many approaches focus on topic-based organization and structuring, hardly any system incorporates automatic structural analysis and representation. Yet, genre information…

Describes the STATUS information retrieval system, which is a free text, Boolean-type system, concentrating on recent developments and improvements. The use of pre- and postprocessors is discussed, and how STATUS can be integrated into existing information systems is illustrated. An appendix lists selected users and applications. (Author/JD)

The Telemakus System builds on the areas of concept representation, schema theory, and information visualization to enhance knowledge discovery from scientific literature. This article describes the underlying theories and an overview of a working implementation designed to enhance the knowledge discovery process through retrieval, visual and…

Demonstrates that if the similarity function of a retrieval system leads to a (pseudo-) metric, the retrieval, similarity and Everett-Cater metric topology coincide and are different from the discrete topology; this is the case if documents are represented by lists, using the Jaccard similarity measure. The corresponding metric is the…
