Existing techniques recom- mend tags on the basis of their popularity among the group of all users; on the basis of recent use; or on the basis of simple heuristics to extract keywords from the url being tagged. Our method is designed to complement these approaches, and is based on recommending tags from urls that are similar to the one in question, according to two distinct similarity metrics, whose principal utility covers complementary cases.</swrc:abstract><swrc:hasExtraField><swrc:Field swrc:value="5" swrc:key="priority"/></swrc:hasExtraField><swrc:author><rdf:Seq><rdf:_1><swrc:Person swrc:name="Andrew Byde"/></rdf:_1><rdf:_2><swrc:Person swrc:name="Hui Wan"/></rdf:_2><rdf:_3><swrc:Person swrc:name="Steve Cayzer"/></rdf:_3></rdf:Seq></swrc:author></rdf:Description><rdf:Description rdf:about="http://www.bibsonomy.org/bibtex/271bc9f8ae1a53632dc9a2b98b017f152/krass"><owl:sameAs rdf:resource="http://www.bibsonomy.org/uri/bibtex/271bc9f8ae1a53632dc9a2b98b017f152/krass"/><rdf:type rdf:resource="http://swrc.ontoware.org/ontology#InProceedings"/><owl:sameAs rdf:resource="http://www.kde.cs.uni-kassel.de/stumme/papers/2007/jaeschke07tagrecommendationsKDML.pdf"/><swrc:date>Tue Nov 13 16:07:39 CET 2007</swrc:date><swrc:booktitle>Workshop Proceedings of Lernen - Wissensentdeckung - Adaptivität (LWA 2007)</swrc:booktitle><swrc:month>sep</swrc:month><swrc:pages>13-20</swrc:pages><swrc:publisher><swrc:Organization swrc:name="Martin-Luther-Universität Halle-Wittenberg"/></swrc:publisher><swrc:title>Tag Recommendations in Folksonomies</swrc:title><swrc:year>2007</swrc:year><swrc:keywords>recommender folksonomies </swrc:keywords><swrc:hasExtraField><swrc:Field swrc:value="978-3-86010-907-6" swrc:key="isbn"/></swrc:hasExtraField><swrc:author><rdf:Seq><rdf:_1><swrc:Person swrc:name="Robert Jaeschke"/></rdf:_1><rdf:_2><swrc:Person swrc:name="Leandro Marinho"/></rdf:_2><rdf:_3><swrc:Person swrc:name="Andreas Hotho"/></rdf:_3><rdf:_4><swrc:Person swrc:name="Lars Schmidt-Thieme"/></rdf:_4><rdf:_5><swrc:Person swrc:name="Gerd Stumme"/></rdf:_5></rdf:Seq></swrc:author><swrc:editor><rdf:Seq><rdf:_1><swrc:Person swrc:name="Alexander Hinneburg"/></rdf:_1></rdf:Seq></swrc:editor></rdf:Description><rdf:Description rdf:about="http://www.bibsonomy.org/bibtex/2b8b87c78e9e27a44aacde0402c642bff/krass"><owl:sameAs rdf:resource="http://www.bibsonomy.org/uri/bibtex/2b8b87c78e9e27a44aacde0402c642bff/krass"/><rdf:type rdf:resource="http://swrc.ontoware.org/ontology#InProceedings"/><owl:sameAs rdf:resource="http://www.kde.cs.uni-kassel.de/hotho/pub/2007/Tag_Recommender_in_Folksonomies_final.pdf"/><swrc:date>Tue Nov 06 09:50:07 CET 2007</swrc:date><swrc:booktitle>Knowledge Discovery in Databases: PKDD 2007, 11th European Conference on Principles and Practice of Knowledge Discovery in Databases, Warsaw, Poland, September 17-21, 2007, Proceedings</swrc:booktitle><swrc:crossref>DBLP:conf/pkdd/2007</swrc:crossref><swrc:pages>506-514</swrc:pages><swrc:publisher><swrc:Organization swrc:name="Springer"/></swrc:publisher><swrc:series>Lecture Notes in Computer Science</swrc:series><swrc:title>Tag Recommendations in Folksonomies</swrc:title><swrc:volume>4702</swrc:volume><swrc:year>2007</swrc:year><swrc:keywords>recommender </swrc:keywords><swrc:hasExtraField><swrc:Field swrc:value="http://dx.doi.org/10.1007/978-3-540-74976-9_52" swrc:key="ee"/></swrc:hasExtraField><swrc:hasExtraField><swrc:Field swrc:value="DBLP, http://dblp.uni-trier.de" swrc:key="bibsource"/></swrc:hasExtraField><swrc:hasExtraField><swrc:Field swrc:value="978-3-540-74975-2" swrc:key="isbn"/></swrc:hasExtraField><swrc:author><rdf:Seq><rdf:_1><swrc:Person swrc:name="Robert Jäschke"/></rdf:_1><rdf:_2><swrc:Person swrc:name="Leandro Balby Marinho"/></rdf:_2><rdf:_3><swrc:Person swrc:name="Andreas Hotho"/></rdf:_3><rdf:_4><swrc:Person swrc:name="Lars Schmidt-Thieme"/></rdf:_4><rdf:_5><swrc:Person swrc:name="Gerd Stumme"/></rdf:_5></rdf:Seq></swrc:author><swrc:editor><rdf:Seq><rdf:_1><swrc:Person swrc:name="Joost N.

The notion of generating a set of recommendations that will satisfy a group of users, with potentially competing interests, is challenging in itself. In addition to this we must consider how to record and combine the preferences of many different users as they engage in simultaneous recommendation dialogs.

Solche Systeme können Produkte, Services, Nutzer (mit analogen Interessen) uvm. vorschlagen und stellen damit – gerade im Web 2.0-Zeitalter – eine besondere Form der Personalisierung sowie des social networking dar. Damit bieten Empfehlungssysteme Anbietern im ECommerce einen entscheidenden Marktvorteil, weshalb die Auswertung der Kundendaten bei großen Firmen wie Amazon, Google oder Ebay eine hohe Priorität besitzt. Aus diesem Grund wird im vorliegenden Artikel auf die Ansätze von Empfehlungssystemen, welche auf unterschiedliche Weise die Bedürfnisse des Nutzers aufgreifen bzw. „vorausahnen“ und ihm Vorschläge (aus verschiedenen Bereichen) unterbreiten können, eingegangen. Der Artikel liefert eine Definition und Darstellung der Arbeitsweisen von Empfehlungssystemen. Dabei werden die verschiedenen Methodiken jener Dienste vergleichend erläutert, um ihre jeweiligen Vor- und Nachteile deutlich zu machen. Außerdem wird der Ontologie- und Folksonomy-Einsatz innerhalb von Empfehlungssystemen beleuchtet, um Chancen und Risiken der Anwendung von Methoden der Wissensrepräsentation für zukünftige Forschungsarbeiten einschätzen zu können. Recommender Systems in an Information Science View – The State of the Art Recommender systems offer content individually to users in the WWW, based on their concrete needs, preferences and interests. Those systems can propose products, services, users (with analogous interests), etc.) and represent a special form of personalisation as well as of social networking – exactly in the Web 2.0 age. Recommender systems offer e.g. suppliers in the e-commerce a crucial market advantage. So, the evaluation of the customer data has high priority at big companies like Amazon, Google or Ebay. For this reason we engaged in recommender systems, which take up the user’s needs in different ways, to “anticipate“ needs and make suggestions (from different areas) to the user. This review article achieves a definition and representation of operations and methods of recommender systems. Exactly the different methodologies of those services should be expounded comparativly on that occasion in order to represent advantages and disadvantages. The use of ontologies and folksonomies as implementations in recommender systems is portrayed in order to be able to take into consideration chances and risks of the application of knowledge representation methods for future researches.</swrc:abstract><swrc:author><rdf:Seq><rdf:_1><swrc:Person swrc:name="Stefanie Höhfeld"/></rdf:_1><rdf:_2><swrc:Person swrc:name="Melanie Kwiatkowski"/></rdf:_2></rdf:Seq></swrc:author></rdf:Description><rdf:Description rdf:about="http://www.bibsonomy.org/bibtex/22c3aea62cafdd8a01a68e3fbed7b4071/krass"><owl:sameAs rdf:resource="http://www.bibsonomy.org/uri/bibtex/22c3aea62cafdd8a01a68e3fbed7b4071/krass"/><rdf:type rdf:resource="http://swrc.ontoware.org/ontology#InProceedings"/><owl:sameAs rdf:resource="http://www.informatik.uni-freiburg.de/cgnm/pub/pdfs/Schmidt-Thieme2005-compound-classifiers-for-recommender-systems.pdf"/><swrc:date>Thu Nov 01 12:39:18 CET 2007</swrc:date><swrc:address>Houston, Texas, USA</swrc:address><swrc:booktitle>Proceedings of the 5th IEEE International Conference on Data Mining (ICDM 2005), 27-30 November 2005</swrc:booktitle><swrc:pages>378-385</swrc:pages><swrc:publisher><swrc:Organization swrc:name="IEEE Computer Society"/></swrc:publisher><swrc:title>Compound Classification Models for Recommender Systems.</swrc:title><swrc:year>2005</swrc:year><swrc:keywords>recommender </swrc:keywords><swrc:hasExtraField><swrc:Field swrc:value="http://doi.ieeecomputersociety.org/10.1109/ICDM.2005.46" swrc:key="ee"/></swrc:hasExtraField><swrc:hasExtraField><swrc:Field swrc:value="DBLP, http://dblp.uni-trier.de" swrc:key="bibsource"/></swrc:hasExtraField><swrc:hasExtraField><swrc:Field swrc:value="0-7695-2278-5" swrc:key="isbn"/></swrc:hasExtraField><swrc:author><rdf:Seq><rdf:_1><swrc:Person swrc:name="Lars Schmidt-Thieme"/></rdf:_1></rdf:Seq></swrc:author></rdf:Description><rdf:Description rdf:about="http://www.bibsonomy.org/bibtex/21df0274ddea4223119f1090f236a6f1f/krass"><owl:sameAs rdf:resource="http://www.bibsonomy.org/uri/bibtex/21df0274ddea4223119f1090f236a6f1f/krass"/><rdf:type rdf:resource="http://swrc.ontoware.org/ontology#InProceedings"/><owl:sameAs rdf:resource="http://www.kde.cs.uni-kassel.de/hotho/pub/2007/Tag_Recommender_in_Folksonomies_final.pdf"/><swrc:date>Thu Nov 01 12:39:06 CET 2007</swrc:date><swrc:booktitle>Knowledge Discovery in Databases: PKDD 2007, 11th European Conference on Principles and Practice of Knowledge Discovery in Databases, Warsaw, Poland, September 17-21, 2007, Proceedings</swrc:booktitle><swrc:crossref>DBLP:conf/pkdd/2007</swrc:crossref><swrc:pages>506-514</swrc:pages><swrc:publisher><swrc:Organization swrc:name="Springer"/></swrc:publisher><swrc:series>Lecture Notes in Computer Science</swrc:series><swrc:title>Tag Recommendations in Folksonomies</swrc:title><swrc:volume>4702</swrc:volume><swrc:year>2007</swrc:year><swrc:keywords>recommender folksonomy </swrc:keywords><swrc:hasExtraField><swrc:Field swrc:value="http://dx.doi.org/10.1007/978-3-540-74976-9_52" swrc:key="ee"/></swrc:hasExtraField><swrc:hasExtraField><swrc:Field swrc:value="DBLP, http://dblp.uni-trier.de" swrc:key="bibsource"/></swrc:hasExtraField><swrc:hasExtraField><swrc:Field swrc:value="978-3-540-74975-2" swrc:key="isbn"/></swrc:hasExtraField><swrc:author><rdf:Seq><rdf:_1><swrc:Person swrc:name="Robert JÃ¤schke"/></rdf:_1><rdf:_2><swrc:Person swrc:name="Leandro Balby Marinho"/></rdf:_2><rdf:_3><swrc:Person swrc:name="Andreas Hotho"/></rdf:_3><rdf:_4><swrc:Person swrc:name="Lars Schmidt-Thieme"/></rdf:_4><rdf:_5><swrc:Person swrc:name="Gerd Stumme"/></rdf:_5></rdf:Seq></swrc:author><swrc:editor><rdf:Seq><rdf:_1><swrc:Person swrc:name="Joost N.
