Calibration: A Simple Way to Improve Click Models by Alexey Borisov, Julia Kiseleva, Ilya Markov, and Maarten de Rijke is available online now at this location. In the paper we show that click models trained with suboptimal hyperparameters suffer from the issue of bad calibration. This means that their predicted click probabilities do not agree…

CIKM 2018 paper on Attentive Encoder-based Extractive Text Summarization online
Attentive Encoder-based Extractive Text Summarization by Chong Feng, Fei Cai, Honghui Chen, and Maarten de Rijke is available online now at this location. In previous work on text summarization, encoder-decoder architectures and attention mechanisms have both been widely used. Attention-based encoder-decoder approaches typically focus on taking the sentences preceding a given sentence in a document…
CIKM 2018 paper on Integrating Text Matching and Product Substitutability within Product Search online
Mix ‘n Match: Integrating Text Matching and Product Substitutability within Product Search by Christophe Van Gysel, Maarten de Rijke, and Evangelos Kanoulas is available online now at this location. Two products are substitutes if both can satisfy the same consumer need. Intrinsic incorporation of product substitutability—where substitutability is integrated within latent vector space models—is in…

Open Science
I’m a professor. My job description is very simple: to create new knowledge and to transfer it. To students, colleagues, and anyone else, really. To academia, industry, governments, and the rest of society. I do my job by working with a large team of very talented PhD students and postdocs from around the planet and…
Now on arXiv: Explainable Fashion Recommendation with Joint Outfit Matching and Comment Generation
Yujie Lin, Pengjie Ren, Zhumin Chen, Zhaochun Ren, Jun Ma, and I published “Explainable Fashion Recommendation with Joint Outfit Matching and Comment Generation” on arXiv. Most previous work on fashion recommendation focuses on designing visual features to enhance recommendations. Existing work neglects user comments of fashion items, which have been proved effective in generating explanations…
Five more vacancies for fully funded PhD students
We just opened five more vacancies for PhD students. The general area is AI for Retail, and the positions are part of the new AIRLab. Areas range from recommendation to federated search and conversational search to replenishment. Deadline: July 16, 2018. Please visit this page for all the details.
Three more papers on arXiv
We’ve just put three more papers on arXiv. Earlier in June, Sapna Negi, Paul Buitelaar, and I put “Open Domain Suggestion Mining: Problem Definition and Datasets” on arXiv. In the paper we propose a formal definition for the task of suggestion mining in the context of a wide range of open domain applications. Human perception…
Another IR vacancy
We just opened another vacancy, for a PhD student to work on dataset search. Come and join us to work in the area of AI & IR, together with great colleagues at Elsevier, VU Amsterdam and KNAW. See https://t.co/um5ldIQAZg for more details.
