- 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
- This is the first comprehensive book on hypermedia nd the WWW that icludes features of the 2nd generation systems. Definitions, history, current technology and problems, leading-edge initiatives, future applications, all these are seen as an unfolding of a millenial communication medium that is not serving but involving even the non-technical person in a very technical world. Much of the promise of hypermedia lies in its applications to education, and this receives prominence in the book. The new hypermedia system 'HyperWave' is described in detail. The book's vision, organization, and easy-to-read style make it suitable as a source for information for the practitioner and the general reader. It may also serve both as a reference book for researchers and as a textbook

- Abstract
- Fast, effective, and adaptable techniques are needed to automatically organize and retrieve information an the ever-increasing World Wide Web. In that respect, different strategies have been suggested to take hypertext links into account. For example, hyperlinks have been used to (1) enhance document representation, (2) improve document ranking by propagating document score, (3) provide an indicator of popularity, and (4) find hubs and authorities for a given topic. Although the TREC experiments have not demonstrated the usefulness of hyperlinks for retrieval, the hypertext structure is nevertheless an essential aspect of the Web, and as such, should not be ignored. The development of abstract models of the IR task was a key factor to the improvement of search engines. However, at this time conceptual tools for modeling the hypertext retrieval task are lacking, making it difficult to compare, improve, and reason an the existing techniques. This article proposes a general model for using hyperlinks based an Probabilistic Argumentation Systems, in which each of the above-mentioned techniques can be stated. This model will allow to discover some inconsistencies in the mentioned techniques, and to take a higher level and systematic approach for using hyperlinks for retrieval.

- 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
- Navigating through hyperlinks within a Web site to look for information from one of its Web pages without the support of a site map can be inefficient and ineffective. Although the content of a Web site is usually organized with an inherent structure like a topic hierarchy, which is a directed tree rooted at a Web site's homepage whose vertices and edges correspond to Web pages and hyperlinks, such a topic hierarchy is not always available to the user. In this work, we studied the problem of automatic generation of Web sites' topic hierarchies. We modeled a Web site's link structure as a weighted directed graph and proposed methods for estimating edge weights based on eight types of features and three learning algorithms, namely decision trees, naïve Bayes classifiers, and logistic regression. Three graph algorithms, namely breadth-first search, shortest-path search, and directed minimum-spanning tree, were adapted to generate the topic hierarchy based on the graph model. We have tested the model and algorithms on real Web sites. It is found that the directed minimum-spanning tree algorithm with the decision tree as the weight learning algorithm achieves the highest performance with an average accuracy of 91.9%.

- Abstract
- This study investigated information retrieval from hypertext on the WWW. Significant main and interaction effects were found for both link density (number of links per display) and display format (in paragraphs or lists) on search performance. Low link densities displayed in list format produced the best overall results, in terms of search accuracy, search time, number of links explored, and search task prioritization. Lower densities affected user ability to prioritize search tasks and produced more accurate searches, while list displays positively affected all aspects of searching except task prioritization. The performance of novices and experts, in terms of their previous experience browsing hypertext on the WWW, was compared. Experts performed better, mostly because of their superior task prioritization

- Abstract
- Most existing hypermedia authoring systems incorporate facilities for the creation of static links between pieces of information, termed nodes. Such links usually support only browsing activities over the hypermedia web, carrying little or no information about the conceptual relationship the nodes might have. Thus indecision occurs: the reader of the hypermedia can traverse a link but has no indication what link to choose and what he might expect from the traversal. At the same time, the creation of these links requires a great effort from the author, moreover if there are certain criteria that guide linking. This paper presents a two-layered hypermedia semantic model that enriches the semantic links, and alsoprovides the means for dynamic link creation. To accomplish these objectives, we adopt the use of fuzzy set theory and fuzzy logic as the mathematical framework for link characterization and dynamic link creation. Some aspects of a prototype system, named Platon, are also presented

- 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
