In addition to reviewing the evaluation strategies used by prior researchers, we present empirical results from the analysis of various accuracy metrics on one content domain where all the tested metrics collapsed roughly into three equivalence classes. Metrics within each equivalency class were strongly correlated, while metrics from different equivalency classes were uncorrelated.</swrc:abstract><swrc:hasExtraField><swrc:Field swrc:value="1046-8188" swrc:key="issn"/></swrc:hasExtraField><swrc:hasExtraField><swrc:Field swrc:value="http://doi.acm.org/10.1145/963770.963772" swrc:key="doi"/></swrc:hasExtraField><swrc:author><rdf:Seq><rdf:_1><swrc:Person swrc:name="Jonathan L.

In this paper, we propose a âcollaborativeannotatingâ approach to automatically recommend categories for a Wikipedia article by reusing category annotations from itsmost similar articles and ranking these annotations by their confidence.

The experiment results have not only proven that these semanticfeatures improve the performance of category annotating, with comparison to the plain text feature; but also demonstratedthe strength of our approach in discovering missing annotations and proper level ones for Wikipedia articles.</swrc:abstract><swrc:author><rdf:Seq><rdf:_1><swrc:Person swrc:name="Yang Wang"/></rdf:_1><rdf:_2><swrc:Person swrc:name="Haofen Wang"/></rdf:_2><rdf:_3><swrc:Person swrc:name="Haiping Zhu"/></rdf:_3><rdf:_4><swrc:Person swrc:name="Yong Yu"/></rdf:_4></rdf:Seq></swrc:author></rdf:Description><rdf:Description rdf:about="http://www.bibsonomy.org/bibtex/2e26b0d4305079fae673c8dcdb1999d68/wnpxrz"><owl:sameAs rdf:resource="http://www.bibsonomy.org/uri/bibtex/2e26b0d4305079fae673c8dcdb1999d68/wnpxrz"/><rdf:type rdf:resource="http://swrc.ontoware.org/ontology#Misc"/><owl:sameAs rdf:resource="/brokenurl#citeseer.ist.psu.edu/terveen01beyond.html"/><swrc:date>Sun Dec 30 11:43:14 CET 2007</swrc:date><swrc:title>Beyond Recommender Systems: Helping People Help Each Other</swrc:title><swrc:year>2001</swrc:year><swrc:keywords>collaborative recommendersystems imported filtering </swrc:keywords><swrc:author><rdf:Seq><rdf:_1><swrc:Person swrc:name="L.

However, CF becomes less effective when users have multiple interests, because users have similar taste in one aspect may behave quite different in other aspects. Information got from social bookmarking websites not only tells what a user likes, but also why he or she likes it. This paper proposes a division algorithm and a CubeSVD algorithm to analysis this information, distill the interrelations between different usersâ various interests, and make better personalized recommendation based on them. Experiment reveals the superiority of our method over traditional CF methods.

of the item and a profile of the userâs interests. Content-based recommendation systems may be used in a variety of domainsranging from recommending web pages, news articles, restaurants, television programs, and items for sale. Although the detailsof various systems differ, content-based recommendation systems share in common a means for describing the items that maybe recommended, a means for creating a profile of the user that describes the types of items the user likes, and a means ofcomparing items to the user profile to determine what to re commend. The profile is often created and updated automaticallyin response to feedback on the desirability of items that have been presented to the user.</swrc:abstract><swrc:author><rdf:Seq><rdf:_1><swrc:Person swrc:name="Michael Pazzani"/></rdf:_1><rdf:_2><swrc:Person swrc:name="Daniel Billsus"/></rdf:_2></rdf:Seq></swrc:author></rdf:Description><rdf:Description rdf:about="http://www.bibsonomy.org/bibtex/296968eb56f0a3b40f7bc008477088309/wnpxrz"><owl:sameAs rdf:resource="http://www.bibsonomy.org/uri/bibtex/296968eb56f0a3b40f7bc008477088309/wnpxrz"/><rdf:type rdf:resource="http://swrc.ontoware.org/ontology#InProceedings"/><owl:sameAs rdf:resource="http://portal.acm.org/citation.cfm?id=1125451.1125659#"/><swrc:date>Sun Nov 04 16:12:11 CET 2007</swrc:date><swrc:address>New York, NY, USA</swrc:address><swrc:booktitle>CHI &#039;06: CHI &#039;06 extended abstracts on Human factors in computing systems</swrc:booktitle><swrc:pages>1097--1101</swrc:pages><swrc:publisher><swrc:Organization swrc:name="ACM"/></swrc:publisher><swrc:title>Being accurate is not enough: how accuracy metrics have hurt recommender systems</swrc:title><swrc:year>2006</swrc:year><swrc:keywords>imported recommendersystems evaluation </swrc:keywords><swrc:abstract>Recommender systems have shown great potential to help users find interesting and relevant items from within a large information space. Most research up to this point has focused on improving the accuracy of recommender systems. We believe that not only has this narrow focus been misguided, but has even been detrimental to the field. The recommendations that are most accurate according to the standard metrics are sometimes not the recommendations that are most useful to users. In this paper, we propose informal arguments that the recommender community should move beyond the conventional accuracy metrics and their associated experimental methodologies. We propose new user-centric directions for evaluating recommender systems.</swrc:abstract><swrc:hasExtraField><swrc:Field swrc:value="Montr\&amp;\#233;al, Qu\&amp;\#233;bec, Canada" swrc:key="location"/></swrc:hasExtraField><swrc:hasExtraField><swrc:Field swrc:value="1-59593-298-4" swrc:key="isbn"/></swrc:hasExtraField><swrc:hasExtraField><swrc:Field swrc:value="http://doi.acm.org/10.1145/1125451.1125659" swrc:key="doi"/></swrc:hasExtraField><swrc:author><rdf:Seq><rdf:_1><swrc:Person swrc:name="Sean M.

We explore the acquisition of user profiles by unobtrusive monitoring of browsing behaviour and application of supervised machine-learning techniques coupled with an ontological representation to extract user preferences. A multi-class approach to paper classification is used, allowing the paper topic taxonomy to be utilised during profile construction. The Quickstep recommender system is presented and two empirical studies evaluate it in a real work setting, measuring the effectiveness of using a hierarchical topic ontology compared with an extendable flat list.</swrc:abstract><swrc:hasExtraField><swrc:Field swrc:value="Victoria, British Columbia, Canada" swrc:key="location"/></swrc:hasExtraField><swrc:hasExtraField><swrc:Field swrc:value="1-58113-380-4" swrc:key="isbn"/></swrc:hasExtraField><swrc:hasExtraField><swrc:Field swrc:value="http://doi.acm.org/10.1145/500737.500755" swrc:key="doi"/></swrc:hasExtraField><swrc:author><rdf:Seq><rdf:_1><swrc:Person swrc:name="Stuart E.

RSs compute a user similarity between users and use it as a weight for the usersrsquo ratings. However they have many weaknesses, such as sparseness, cold start and vulnerability to attacks. We assert that these weaknesses can be alleviated using a Trust-aware system that takes into account the ldquoweb of trustrdquo provided by every user. Specifically, we analyze data from the popular Internet web site epinions.com. The dataset consists of 49290 users who expressed reviews (with rating) on items and explicitly specified their web of trust, i.e. users whose reviews they have consistently found to be valuable. We show that any two users have usually few items rated in common. For this reason, the classic RS technique is often ineffective and is not able to compute a user similarity weight for many of the users. Instead exploiting the webs of trust, it is possible to propagate trust and infer an additional weight for other users. We show how this quantity can be computed against a larger number of users.
