A Scale-Consistent Approach for Recommender Systems

A relatively simple and efficient approach for estimating unknown elements of a user-rating matrix in the context of a recommender system and its consistency with respect to arbitrary units implicitly adopted by different users to construct their quantitative ratings of products is proposed.

A Recommender System Based on Multi-Criteria Aggregation

A recommender system that uses the Choquet integral of a fuzzy measure to determine a total ordering of the alternatives and to aggregate performance measures over all criteria based on inferences about preferences from the decision-maker’s input is presented.

Towards User Profile Modelling in Recommender System

The different aspects of the user's profile are treated, defining it, profile, its features and its indicators of interest, and then the different approaches of modelling and acquiring the user’s interests are described.

Multi-Criteria Recommender Systems based on Multi-Attribute Decision Making

This method proposes a correlation coefficient and standard deviation integrated approach for determining weight of criteria in multi-criteria recommender systems and was compared to some other metrics used in Information Theoretic approach to illustrate its potential applications.

Review of Multi Criteria Recommender Systems and its Issues

The approaches followed in Collaborative Recommender Systems using multiple criteria ratings are reviewed, issues in this area and extension possibilities are reviewed.

Advanced Topics in Recommender Systems

This chapter studies the following advanced variations of recommender systems, which are often used in specialized settings where there might be multiple users or multiple evaluation criteria.

The Implication of Context and Criteria Information in Recommender Systems as applied to the Service Domain

This thesis investigates the inclusion of criteria and context information in the recommendation process with a novel technique for multi-criteria recommendation and a context similarity metric for context aware recommendation.

Multi-criteria service recommendation based on user criteria preferences

A novel approach to multi-criteria recommendation, based on the idea of clustering users in "preference lattices" according to their criteria preferences, is presented, which indicates that the third method, which combines clustering and extended collaborative filtering, produces the highest accuracy.



UTA-Rec: a recommender system based on multiple criteria analysis

The results indicate that the proposed Multiple Criteria Analysis methodology can certainly improve the recommendation process by producing highly accurate results, from a user oriented perspective.

New Recommendation Techniques for Multicriteria Rating Systems

This article proposes several new techniques for extending recommendation technologies to incorporate and leverage multicriteria rating information and improve recommendation accuracy as compared with single-rating recommendation approaches.

Guest Editors' Introduction: Recommender Systems

This special issue presents eight articles, five long and three short, on techniques to improve recommender systems. They cover improving such aspects as user interaction with recommenders, the

Evaluating collaborative filtering recommender systems

The key decisions in evaluating collaborative filtering recommender systems are reviewed: the user tasks being evaluated, the types of analysis and datasets being used, the ways in which prediction quality is measured, the evaluation of prediction attributes other than quality, and the user-based evaluation of the system as a whole.

Making recommendations better: an analytic model for human-recommender interaction

It is argued that recommenders need a deeper understanding of users and their information seeking tasks and recommender algorithms using a common language and an analytic process model.

Applying probabilistic latent semantic analysis to multi-criteria recommender system

Two types of multi-criteria probabilistic latent semantic analysis algorithms extended from the single-rating version are proposed, inspired by the Bayesian network and linear regression.

Toward the next generation of recommender systems: a survey of the state-of-the-art and possible extensions

This paper presents an overview of the field of recommender systems and describes the current generation of recommendation methods that are usually classified into the following three main

Mediation of user models for enhanced personalization in recommender systems

A generic user modeling data representation model is provided, which demonstrates its compatibility with existing recommendation techniques, and allows improving the quality of the recommendations provided to the users in certain conditions.

Ontological user profiling in recommender systems

Ontological inference is shown to improve user profiling, external ontological knowledge used to successfully bootstrap a recommender system and profile visualization employed to improve profiling accuracy are shown.

Evaluation and Decision Models with Multiple Criteria: Stepping Stones for the Analyst

This work presents a meta-modelling architecture suitable for multi-Dimensional preference models and shows clear trends in preference-based decision-making that have been identified in recent years.
