Abstract

Recommender systems are becoming increasingly indispensable for e-commerce. To achieve interpretable recommendation, review topic-based recommendation is an important research area that aims to infer users’ ratings over their unrated items using existing reviews and corresponding ratings simultaneously. However, combining latent factors and review topics can also introduce uncertainties in the model learning process, both in inference and sampling. To address this challenge, we propose a new model called type-2 fuzzy review topic-based recommendation (T2FR). T2 fuzzy membership functions are introduced to represent the topic parameter uncertainties, and a strategy of dual sampling is developed to deal with the topic T2 membership functions and further used for uncertainty handling. Abundant experiments on data collected from real-world e-commerce platforms demonstrate the effectiveness of the proposed model compared with baseline methods in terms of rating prediction accuracy with interpretation. Our proposed T2FR can substantially benefit both e-commerce platforms and consumers.

基于第 2 类模糊评论主题的个性化推荐模型
推荐系统在电子商务中越来越不可或缺。为了实现可解释的推荐,基于评论主题的推荐是一个重要的研究领域,其目的是同时利用现有的评论和相应的评分来推断用户对其未评分商品的评分。然而,将潜在因素和评论主题相结合也会在模型学习过程中引入不确定性,包括推断和抽样。为了应对这一挑战,我们提出了一种新的模型,称为基于评论主题的 2 型模糊推荐(T2FR)。我们引入了 T2 模糊成员函数来表示主题参数的不确定性,并开发了双采样策略来处理主题 T2 成员函数,并进一步用于不确定性处理。在真实世界电子商务平台收集的数据上进行的大量实验证明,与基线方法相比,所提出的模型在评级预测准确性和解释方面非常有效。我们提出的 T2FR 可以使电子商务平台和消费者受益匪浅。

期刊介绍: The Internet and the World Wide Web have brought a fundamental change in the way that individuals access data, information and services. Individuals have access to vast amounts of data, to experts and services that are not limited in time or space. This has forced business to change the way in which they conduct their commercial transactions with their end customers and with other businesses, resulting in the development of a global market through the Internet. The emergence of the Internet and electronic commerce raises many new research issues. The Electronic Commerce Research journal will serve as a forum for stimulating and disseminating research into all facets of electronic commerce - from research into core enabling technologies to work on assessing and understanding the implications of these technologies on societies, economies, businesses and individuals. The journal concentrates on theoretical as well as empirical research that leads to better understanding of electronic commerce and its implications. Topics covered by the journal include, but are not restricted to the following subjects as they relate to the Internet and electronic commerce: Dissemination of services through the Internet;Intelligent agents technologies and their impact;The global impact of electronic commerce;The economics of electronic commerce;Fraud reduction on the Internet;Mobile electronic commerce;Virtual electronic commerce systems;Application of computer and communication technologies to electronic commerce;Electronic market mechanisms and their impact;Auctioning over the Internet;Business models of Internet based companies;Service creation and provisioning;The job market created by the Internet and electronic commerce;Security, privacy, authorization and authentication of users and transactions on the Internet;Electronic data interc hange over the Internet;Electronic payment systems and electronic funds transfer;The impact of electronic commerce on organizational structures and processes;Supply chain management through the Internet;Marketing on the Internet;User adaptive advertisement;Standards in electronic commerce and their analysis;Metrics, measurement and prediction of user activity;On-line stock markets and financial trading;User devices for accessing the Internet and conducting electronic transactions;Efficient search techniques and engines on the WWW;Web based languages (e.g., HTML, XML, VRML, Java);Multimedia storage and distribution;Internet;Collaborative learning, gaming and work;Presentation page design techniques and tools;Virtual reality on the net and 3D visualization;Browsers and user interfaces;Web site management techniques and tools;Managing middleware to support electronic commerce;Web based education, and training;Electronic journals and publishing on the Internet;Legal issues, taxation and property rights;Modeling and design of networks to support Internet applications;Modeling, design and sizing of web site servers;Reliability of intensive on-line applications;Pervasive devices and pervasive computing in electronic commerce;Workflow for electronic commerce applications;Coordination technologies for electronic commerce;Personalization and mass customization technologies;Marketing and customer relationship management in electronic commerce;Service creation and provisioning. Audience: Academics and professionals involved in electronic commerce research and the application and use of the Internet. Managers, consultants, decision-makers and developers who value the use of electronic com merce research results. Special Issues: Electronic Commerce Research publishes from time to time a special issue of the devoted to a single subject area. If interested in serving as a guest editor for a special issue, please contact the Editor-in-Chief J. Christopher Westland at westland@uic.edu with a proposal for the special issue.
