Abstract

This chapter is intended to introduce the basic techniques for general recommender systems, as well as specific research for video recommendation, which have become interesting and important topics in video search and mining. We will first define video recommendation and survey three principle approaches to video recommendation, i.e., collaborative filtering, content-based, and hybrid approaches. We will also discuss the connection and difference between video recommendation and search. Then, we will introduce several recent exemplary systems for recommendation, including: (1) “graph-based video recommendation” which builds random work graph based on user-video pairs [5], (2) “contextual video recommendation by multimodal relevance and user feedback” which does not require a large collection of user profiles [30, 43], and (3) “consumer generated video recommendation” which discusses ranking distances for recommendation and proposes an edit-distance for ranking [22]. The first system uses collaborative filtering-based recommendation approach, while the latter two belong to content-based recommendation.
