2018 Workshop on ExplainAble Recommendation and Search (EARS 2018)

Co-located with The 41st International ACM SIGIR Conference on Research and Development in Information Retrieval

About

The motivation of the workshop is to promote the research and application of Explainable Recommendation and Search, under the background of Explainable AI in a more general sense. Explainable recommendation and search attempt to develop models or methods that not only generate high-quality recommendation or search results, but also intuitive explanations of the results for users or system designers, which can help improve the system transparency, persuasiveness, trustworthiness, and effectiveness, etc.

In a broader sense, researchers in the whole artificial intelligence community have also realized the importance of Explainable AI, which aims to address a wide range of AI explainability problems in deep learning, computer vision, automatic driving systems, and natural language processing tasks. As an important branch of AI research, this highlights the importance our IR/RecSys community to address the explainability issues of various recommendation and search systems.

We welcome contributions of both long and short papers from a wide range of topics, including but not limited to explainable recommendation and search models, incorporating multi-modal information for explanation, evaluation of explainable recommendation and search, user study for explainable recommendation and search, etc. More topics are listed in the call for papers.

Keynote

Title: Shakespeare of Alibaba: Practice of Intelligent Recommendation Reason Generation in Alibaba

Abstract: Explainable recommendation and search is a very promising topic in both academia and industry in the recent years. There are many human generated recommendation reasons for products in Alibaba Taobao to improve user experience and to increase user stickiness. However, relying on human-generated content will result in low coverage, low quality stability, and high financial expenditure. With the rapid development of deep learning technology in NLP, especially in the nature language generation field, we tried natural language generation approach in recommendation reason generation and achieved good results. We created recommendation reasons for auction and auction list, which covered millions of product categories in Taobao e-commerce, and the generated explanations were used for large-scale real-world trasactions in "2017 Double 11 Shopping Festival" without any manual checking. Industry-level real system experiments show that it was very difficult to distinguish whether the explanations are machine-generated or manually-written, and the content generation can be controlled in multiple dimensions such as text style, text length, topics, etc. We will introduce our solution and technical details about generating free-text explanations in this keynote.

Bio: Dr. Qingsong Hua has been working in Alibaba search algorithm team since 2013 and has led a lot of projects about search relevance, quality, and conversion effectiveness. He is responsible for the intelligent recommendation reason generation project, which won the biggest Alibaba technical award in "2017 Double 11 Online Shopping Festival". He is now responsible for the overall international search algorithm team in Alibaba.
