An experiment in building profiles in information filtering: the role of context of user relevance feedback

Luz M Quiroga, Javed Mostafa
2002 Information Processing & Management  
An experiment was conducted to see how relevance feedback could be used to build and adjust profiles to improve the performance of filtering systems.  ...  The low performance obtained by the implicit acquisition mode motivated the second phase of the study, which aimed to clarify the role of context in relevance feedback judgments.  ...  The role of context in the process of retrieval, filtering and organization of information Since the mid-1960s researchers in IR have experimented with the use of relevance feedback to reformulate a query  ...

Agent mediated collaborative web page filtering [chapter]

Shaw Green, Pádraig Cunningham, Fergal Somers
1998 Lecture Notes in Computer Science  
A prototype system was built using this architecture, which draws upon a user's innate ability to determine the relevance of web pages to their own information needs.  ...  Intelligent filtering of multimedia documents such as World Wide Web (WWW) pages is an extremely difficult task to automate.  ...  In the case of Amalthaea the information available is in the form of user feedback on presented links.  ...

Interactive collaborative filtering

Xiaoxue Zhao, Weinan Zhang, Jun Wang
2013 Proceedings of the 22nd ACM international conference on Conference on information & knowledge management - CIKM '13  
In this paper, we study collaborative filtering (CF) in an interactive setting, in which a recommender system continuously recommends items to individual users and receives interactive feedback.  ...  This requires us not to distinguish between the stages of collecting information to construct the user profile and making recommendations, but to seamlessly integrate these stages together during the interactive  ...  The scenario is also different from common relevance feedback in information retrieval, which normally handles the feedback in one or two iterations and lacks an established way to balance the exploration  ...

Burst the Filter Bubble: Using Semantic Web to Enable Serendipity [chapter]

Valentina Maccatrozzo
2012 Lecture Notes in Computer Science  
Personalization techniques aim at helping people dealing with the ever growing amount of information by filtering it according to their interests.  ...  However, to avoid the information overload, such techniques often create an over-personalization effect, i.e. users are exposed only to the content systems assume they would like.  ...  Acknowledgments This research is supported by the FP7 STREP "ViSTA-TV" project, as well as partially supported by the FP7 IP "NoTube" project and the ONR Global NICOP "COMBINE" project.  ...

2001 Computing and Information Technologies  
With the current growth of the information available in Internet, users are facing an information overload. This work proposes a multiagent system for Web pages personalized filtering.  ...  The system is composed of a set of autonomous and adaptive agents that automatically provide relevant documents to the user according to a preferences profile.  ...  Information filtering systems assist users by filtering the data stream and delivering the relevant information to the user.  ...

Collaborative filtering algorithms can predict the preferences of a target user by looking at the past behavior of similar users.  ...  As collaborative filtering algorithms learn from these patterns to predict preferences and build recommendations, they can homogenize the behavior of dating app users and exacerbate biased sexual and romantic  ...  In other words, by collecting data on the preferences of users collectively, the algorithm predicts the preferences of an individual user, builds recommendations that match those preferences, and filters  ...

Text Categorization for Internet Content Filtering

José M. Gómez, Ignacio Giráldez, Manuel de Buenaga
2004 Inteligencia Artificial  
Text Filtering is one of the most challenging and useful tasks in the Multilingual Information Access field.  ...  In a number of filtering applications, Automated Text Categorization of documents plays a key role.  ...  Filtering by Text Categorization Text Filtering (TF) is a text classification task in which a "system sifts through a stream of arriving information to find documents relevant to a set of user profiles  ...

Context-Aware Collaborative Filtering System: Predicting the User's Preference in the Ubiquitous Computing Environment [chapter]

Annie Chen
2005 Lecture Notes in Computer Science  
We extend collaborative filtering techniques so that what other like-minded users have done in similar context can be used to predict a user's preference towards an activity in the current context.  ...  In this paper we present a context-aware collaborative filtering system that predicts a user's preference in different context situations based on past experiences.  ...  Building a User Profile The first stage of a CF process is to build user profiles from feedback (generally in the form of ratings) on items made over time.  ...

Detection of shifts in user interests for personalized information filtering

W. Lam, S. Mukhopadhyay, J. Mostafa, M. Palakal
1996 Proceedings of the 19th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '96  
While the lower level consists of a standard convergence-type machine learning algorithm, the higher level uses Bayesiart analysis of the user provided relevance feedback to detect shifts in user interests  ...  Several machine learning approaches have been proposed in the literature to automatically learn user interests for information filtering.  ...  The objective is to estimate the user profile from the feedback data so that the filtering system can effectively choose and present information as relevant to the user as possible.  ...

Filtering for Profile-Biased Multi-document Summarization [chapter]

Sana Leila Châar, Olivier Ferret, Christian Fluhr
2005 Lecture Notes in Computer Science  
In this article, we present an information filtering method that selects from a set of documents their most significant excerpts in relation to a user profile.  ...  The topical analysis is also used for expanding a profile in relation to a particular document by selecting the terms of the document that are closely linked to those of the profile.  ...  The detection of inferred terms is quite similar to the blind relevance feedback used in Information Retrieval.  ...

A multilevel approach to intelligent information filtering: model, system, and evaluation

J. Mostafa, S. Mukhopadhyay, M. Palakal, W. Lam
1997 ACM Transactions on Information Systems  
The user's interests are automatically learned with only limited user intervention in the form of optional relevance feedback for documents.  ...  In information-filtering environments, uncertainties associated with changing interests of the user and the dynamic document stream must be handled efficiently.  ...  ACKNOWLEDGMENTS The authors would like to express their sincere appreciation of the assistance provided by Derek Kern, Tanya Blekher, and Todd Kirk in developing the prototype of SIFTER.  ...

A network-based model for high-dimensional information filtering

Nikolaos Nanas, Manolis Vavalis, Anne De Roeck
2010 Proceeding of the 33rd international ACM SIGIR conference on Research and development in information retrieval - SIGIR '10  
We argue that the complexity and dynamics of Information Filtering require user profile representations which are resilient and resistant to this "curse of dimensionality".  ...  The Vector Space Model has been and to a great extent still is the de facto choice for profile representation in contentbased Information Filtering.  ...  IF has an important role to play in achieving personalised information delivery to ensure that the right information reaches the right people.  ...
