- Abstract
- Considering repositories of web documents that are semantically linked and created in a collaborative fashion, as in the case of Wikipedia, a key problem faced by content providers is the placement of links in the articles. These links must support user navigation and provide a deeper semantic interpretation of the content. Current wikification methods exploit machine learning techniques to capture characteristics of the concepts and its associations. In previous work, we proposed a preliminary prediction model combining traditional predictors with a latent component which captures the concept graph topology by means of matrix factorization. In this work, we provide a detailed description of our method and a deeper comparison with a state-of-the-art wikification method using a sample of Wikipedia and report a gain up to 13% in F1 score. We also provide a comprehensive analysis of the model performance showing the importance of the latent predictor component and the attributes derived from the associations between the concepts. Moreover, we include an analysis that allows us to conclude that the model is resilient to ambiguity without including a disambiguation phase. We finally report the positive impact of selecting training samples from specific content quality classes.

- Abstract
- Hypertext, eine neue Art der Informationsdarstellung, ist innerhalb weniger Jahre zu einem auf zahlreichen Fachkonferenzen diskutierten Thema im Umfeld von Informatik, Informationswissenschaft, K?nstlicher Intelligenz, Linguistik, Psychologie und Lerntheorie geworden. Die Faszination, die von diesem Medium auf Forschung, Entwicklung und Anwendung gleicherma~en ausgeht, beruht auf der prinzipiell nichtlinearen Organisation der Hypertexteinheiten und den benutzerfreundlichen Formen des ebenfalls nichtlinearen, flexiblen Zugriffs auf die Einheiten in einem Hypertextsystem. In dieser Einf?hrung in die Hypertextmethodik werden die wesentlichen Elemente von Hypertextsystemen, die Informationseinheiten und Verkn?pfungsarten sowie die hypertextspezifischen Navigationsformen, ausf?hrlich theoretisch und anschaulich am Beispiel existierender kommerzieller und experimenteller Hypertextsysteme behandelt. Besonderer Wert wird auf den Zusammenhang von Hypertext und Information Retrieval und die Einsatzm÷glichkeiten von Hypertext in Lernumgebungen gelegt. In theoretischer Hinsicht wird untersucht, ob sich Hypertextbenutzer mit Vorteil gegen?ber anderen Medien die Information erarbeiten k÷nnen, die sie aktuell in kritischen Situationen ben÷tigen, ob und wodurch also gegen?ber traditionellen linearen Formen ein ~informationeller Mehrwert~ erzielt wird. Au~erdem wird die M÷glichkeit diskutiert, mit Hilfe von Textanalyseverfahren und Techniken der Wissensrepr"sentation Hypertexte aus Texten automatisch aufzubauen. Das Buch enth"lt eine umfassende Bibliographie und im Anhang ein Glossar und eine strukturierte Beschreibung der wichtigsten gegenw"rtig erh"ltlichen oder in Entwicklung befindlichen Hypertextsysteme.

- Abstract
- This article examines searcher behavior and affective response to a hypertext-based bibliographic information retrieval system called HyperLynx for searchers with different search skills and backgrounds. Search times and number of nodes visited were recorded for five specified search queries, and views of the system were recorded for each searcher. No significant differences were found in search times or user satisfaction with the system, indicating that a hypertext-based approach to bibliographic retrieval could be appropriate for a variety of searcher experience levels

- Abstract
- The history of encyclopedias and wholly new forms of encyclopedias are briefly reviewed. The possibilities and problems that hypertext presents as a basis for new forms of encyclopedias are explored. The capabilities of current systems, both experimental and commercially available, are outlined, focusing on new possibilities for authoring and design and for reading the retrieval. Examples of applications already making use of hypertext are given.

- Abstract
- The node size that should be used in a hypermedia system is an important design issue. 3 interpretations of node size are identified: storage (physical size), window size (presentation size), and length (logical size). an experiment in which presentation size and text length are varied in a HyperCard application is described. The experiment involves student subjects performing a fact retrieval task from a reference handbook. No interaction is found between these 2 independent variables. Performance is significantly better for the longer texts, but no significant difference is found for the 2 different window sizes

- Abstract
- Discussions and presentations dealt with attempts to clarify the different concepts in multimedia, object-oriented methods for multimedia, multimedia from psychological perspectives, synchronization problems in multimedia, ccoperative work using multimedia, multimedia interface builders, and so on. There was also a small exhibition presenting 4 different systems ranging from commercial products to research prototypes. The book is divided into 8 parts, on fundamentals, interaction, synchronization, demonstration presentations, cooperative work, information systems, multimedia systems and conclusions

- Abstract
- Fortschrittliche Informationssysteme stellen ihren Benutzern 2 wichtige Suchmethoden zur Verfügung: die gezielte (Volltext-) Suche und das Navigieren im Objektbestand mit Hilfe von Hypertext-Links. Der Grund, warum diese beiden Konzepte aber auf breiter Basis noch nicht in jedem Informationssystem Anwendung gefunden haben, ist darin zu sehen, daß der manuelle Aufbau von umfassenden Hypertext-Strukturen auf der einen Seite und von großen Thesauri, die den Erfolg von Volltextsuchen wesentlich steigern, auf der anderen Seite bislang enormen Aufwand und damit hohe Kosten verursachte. Langfristig werden Informationssysteme aber nur dann große Akzeptanz bei der Benutzerschaft erzielen, wenn sie ihre Benutzer mit diesen beiden Techniken unterstützen und wenn sie dynamisch neuen Informationsbedürfnissen anpassen können, also lernfähig sind. Für den einzelnen Benutzer ergibt sich daraus der wesentliche Vorteil, daß er von den Recherche-Erfahrungen anderer Benutzer profitieren kann. In diesem Papier stellen wir eine Lernkomponente vor, die für das Hypertextsystem 'HyperMan' an der TU München entwickelt und implementiert wurde. Wir zeigen beispielhaft, wie Volltext-Suchanfragen der HyperMan-Benutzer von der Lernkomponente untersucht werden, um Thesauruseinträge zu gewinnen. Bei der Entwicklung dieser Lerntechniken zum (automatischen) Thesaurusaufbau konnte auf Erfahrungen mit dem lernfähigen Information Retrieval System 'Tegen' zurückgegriffen werden. In dem HyperMan System werden aber nicht nur Beziehungen (Relationen) zwischen Begriffen erlernt, sondern auch zwischen Textstücken. Wir gehen daher auch darauf ein, wie aufgrund einer Analyse des Benutzerverhaltens sowohl neue Hypertext-Links erlernt als auch vorhandene Links, die zuvor von HyperMans Generierungskomponente automatisch erzeugt wurden, modifiziert werden

- Abstract
- Presents a new way to tackle the well known 'getting lost sydrome' in hypertext systems by using expertext, or the integration of expert systems with hypertext. Focuses on automatic users' guidance. Presents intelligent Automatic Search Guidance which applies a frame-based representation scheme and object oriented techniques to incorporate an intelligent thesaurus into a meta system for powerful search guidance. It also integrates any specific knowledge that is stored in the information scientist's expertise, terms similarity, and any other data that was gathered in past research trials
