A number of questions remain unanswered, however, regarding the nature of collaborative tagging systems including whether coherent categorization schemes can emerge from unsupervised tagging by users. This paper uses data from the social bookmarking site del.icio.us to examine the dynamics of collaborative tagging systems. In particular, we examine whether the distribution of the frequency of use of tags for "popular" sites with a long history (many tags and many users) can be described by a power law distribution, often characteristic of what are considered complex systems. We produce a generative model of collaborative tagging in order to understand the basic dynamics behind tagging, including how a power law distribution of tags could arise. We empirically examine the tagging history of sites in order to determine how this distribution arises over time and to determine the patterns prior to a stable distribution. Lastly, by focusing on the high-frequency tags of a site where the distribution of tags is a stabilized power law, we show how tag co-occurrence networks for a sample domain of tags can be used to analyze the meaning of particular tags given their relationship to other tags.http://www.bibsonomy.org/bibtex/2a35d5557071e4313104ff000f9b9ae17/zokazoka2008-11-12T15:35:19+01:00development taxonomy wismasys0809 <span class="authorEditorList"><a href="/author/Choksy">C.E.B.

It appeared that the most important consideration was the specificity of the index terms; within the context of the conditions existing in this test, single-word terms were more effective than concept terms or a controlled vocabulary.http://www.bibsonomy.org/bibtex/27c6e7157ec7e135a07406ac04d9224e2/zokazoka2008-11-12T15:10:18+01:00indexing performance retrieval wismasys0809 <span class="authorEditorList"><a href="/author/Soergel">Dagobert Soergel</a> </span> (<em>1994</em>)Wed Nov 12 15:10:18 CET 2008Indexing and retrieval performance: The logical evidence1994indexing performance retrieval wismasys0809 This article presents a logical analysis of the characteristics of indexing and their effects on retrieval performance. It establishes the ability to ask the questions one needs to ask as the foundation of performance evaluation, and recall and discrimination as the basic quantitative performance measures for binary noninteractive retrieval systems. It then defines the characteristics of indexing that affect retrieval-namely, indexing devices, viewpoint-based and importance-based indexing exhaustivity, indexing specificity, indexing correctness, and indexing consistency ― and examines in detail their effects on retrieval. It concludes that retrieval performance depends chiefly on the match between indexing and the requirements of the individual query and on the adaptation of the query formulation to the characteristics of the retrieval system, and that the ensuing complexity must be considered in the design and testing of retrieval systems http://www.bibsonomy.org/bibtex/2a1e023450cb48b287cabf9023d7ab414/zokazoka2008-11-12T15:09:10+01:00Information_Retrieval ontology wismasys0809 <span class="authorEditorList"><a href="/author/Kabel">Suzanne Kabel</a> </span> (<em>2004</em>)Wed Nov 12 15:09:10 CET 2008 The added value of task and ontology-based markup for information retrieval2004Information_Retrieval ontology wismasys0809 In this report, we investigate how retrieving information can be improved through task-related indexing of documents based on ontologies. Different index types, varying from content-based keywords to structured task-based indexing ontologies, are compared in an experiment that simulates the task of creating instructional material from a database of source material. To be able to judge the added value of task- and ontology-related indexes, traditional information retrieval performance measures are extended with new measures reflecting the quality of the material produced with the retrieved information. The results of the experiment show that a structured task-based indexing ontology improves the quality of the product created from retrieved material only to some extent, but that it certainly improves the efficiency and effectiveness of search and retrieval and precision of use.http://www.bibsonomy.org/bibtex/2a09ab1b7eb8ec75891d69d1156e62805/zokazoka2008-11-12T15:06:25+01:00GeoSearcher location-based wismasys0809 <span class="authorEditorList"><a href="/author/Watters">G.

Brachman</a> </span>(<em>2004</em>)Wed Nov 12 14:48:13 CET 2008Knowledge Representation and Reasoning2004Wissensrepräsentation wismasys0809 Knowledge representation is at the very core of a radical idea for understanding intelligence. Instead of trying to understand or build brains from the bottom up, its goal is to understand and build intelligent behavior from the top down, putting the focus on what an agent needs to know in order to behave intelligently, how this knowledge can be represented symbolically, and how automated reasoning procedures can make this knowledge available as needed. This landmark text takes the central concepts of knowledge representation developed over the last 50 years and illustrates them in a lucid and compelling way. Each of the various styles of representation is presented in a simple and intuitive form, and the basics of reasoning with that representation are explained in detail. This approach gives readers a solid foundation for understanding the more advanced work found in the research literature. The presentation is clear enough to be accessible to a broad audience, including researchers and practitioners in database management, information retrieval, and object-oriented systems as well as artificial intelligence. This book provides the foundation in knowledge representation and reasoning that every AI practitioner needs.http://www.bibsonomy.org/bibtex/2d2c01f2a70054d046eb09fd4ecf74d13/zokazoka2008-11-12T14:44:54+01:00Abstracting Indexing Klassifikation Thesaurus Wissensorganisation inhaltliche_Erschließung wismasys0809 <span class="authorEditorList"><a href="/author/Bertram">Jutta Bertram</a> </span>(<em>2005</em>)Wed Nov 12 14:44:54 CET 2008Einführung in die inhaltliche Erschließung: Grundlagen - Methoden - Instrumente2005Abstracting Indexing Klassifikation Thesaurus Wissensorganisation inhaltliche_Erschließung wismasys0809 Die inhaltliche Erschließung geht von der Frage aus, wie man sich gezielt und schnell einen Zugang zu Dokumentinhalten und eine Orientierung über sie verschaffen kann. Vor dem Hintergrund einer Unterscheidung zwischen Begriffen und Bezeichnungen identifiziert das Buch zunächst typische Probleme bei der Suche nach Dokumentinhalten. Es führt in die Methoden der Inhaltserschließung ein (Indexieren, Abstracting) und stellt mit Thesauri und Klassifikationen Erschließungsinstrumente vor, die eine Brückenfunktion erfüllen zwischen jenen, die Informationen suchen und jenen, die sie aufbereiten. Am Beispiel des Internet wird ein konkreter Anwendungsbereich der Inhalterschließung zum Thema gemacht. Die Publikation richtet sich vornehmlich an Teilnehmer und Lehrende von Hochschulstudiengängen im Bibliotheks-, Informations- und Dokumentationsbereich.http://www.bibsonomy.org/bibtex/2582ff4607c92b0142ba5ff56e0b25ba1/zokazoka2008-11-12T14:40:40+01:00adaptive_hypermedia wismasys0809 <span class="authorEditorList"><a href="/author/Brusilovsky"> Brusilovsky</a> </span><em>User Modeling and User-Adapted Interaction</em> (<em>2001</em>)Wed Nov 12 14:40:40 CET 2008User Modeling and User-Adapted Interaction87-110Adaptive hypermedia112001adaptive_hypermedia wismasys0809
