Special Issue Information

Dear Colleagues,

Every day, we interact with predictive systems that seek to model our behavior, monitor our activities, and make recommendations: Whom will we befriend? What articles will we like? Who influences us in our social network? And do our activities change over time? Models that answer such questions drive important real-world systems, and at the same time are of basic scientific interest to economists, linguists, and social scientists, among others. Recommender Systems and Collaborative Filtering algorithms seek to model such problems, while incorporating ideas from related areas including social network analysis, time-series modeling, and natural language processing.

The open access journal Algorithms will host a Special Issue on “Collaborative Filtering Algorithms”. The goal of the Special Issue is to collect new ideas and techniques related to the design and analysis of recommender systems and collaborative filtering algorithms, covering topics including approximation algorithms, scalability, usability and interpretability, and deployment.

Providing model-generated explanations in recommender systems is important to user experience. State-of-the-art recommendation algorithms—especially the collaborative filtering (CF)- based approaches with shallow or deep models—usually work with various unstructured information sources for recommendation, such as textual reviews, visual images, and various implicit or explicit feedbacks. Though structured knowledge bases were considered in content-based approaches, they have been largely ignored recently due to the availability of vast amounts of data and the learning power of many complex models. However, structured knowledge bases exhibit unique advantages in personalized recommendation systems. When the explicit knowledge about users and items is considered for recommendation, the system could provide highly customized recommendations based on users’ historical behaviors and the knowledge is helpful for providing informed explanations regarding the recommended items. A great challenge for using knowledge bases for recommendation is how to integrate large-scale structured and unstructured data, while taking advantage of collaborative filtering for highly accurate performance. Recent achievements in knowledge-base embedding (KBE) sheds light on this problem, which makes it possible to learn user and item representations while preserving the structure of their relationship with external knowledge for explanation. In this work, we propose to explain knowledge-base embeddings for explainable recommendation. Specifically, we propose a knowledge-base representation learning framework to embed heterogeneous entities for recommendation, and based on the embedded knowledge base, a soft matching algorithm is proposed to generate personalized explanations for the recommended items. Experimental results on real-world e-commerce datasets verified the superior recommendation performance and the explainability power of our approach compared with state-of-the-art baselines.
