Explainable Recommendation and Search refers to the (personalized) recommendation and search algorithms that not only provide the user with the search and recommendation results, but also let the user know why such results are provided, i.e., they try to address the problem of “why” in recommendation and search systems. Explainable recommendation and search algorithms devise interpretable models and generates intuitive explanations for users. The explanations can be provided in various forms, such as word clouds, sentences, visual images, or diagrams, etc, which help to improve the effectiveness, efficiency, persuasiveness, and user satisfaction of recommendation and search systems.
