Multimedia Information Retrieval

My main research interests include product search and visual question answering (VQA), lying in the field of information retrieval (IR), which aims to obtain information system resources relevant to an information need from a collection. Product search focuses on the E-commerce domain and aims to retrieve products which are not only relevant to the submitted queries but also fit users' personal preferences; Visual question answering aims to provide a natural language answer for a given image and a free-form, open-ended, natural-language question about this image, which requires semantic understanding on natural language and visual content, as well as knowledge extraction and logic reasoning.
