Incorporating vertical results into search click models
TL;DR: Experimental results show that the new Vertical-aware Click Model (VCM) is better at interpreting user click behavior on federated searches in terms of both log-likelihood and perplexity than existing models.
Proceedings ArticleDOI
From Skimming to Reading: A Two-stage Examination Model for Web Search
TL;DR: This study designs an experimental search engine to collect both the user's feedback on their examinations and the eye-tracking/click-through data and proposes a two-stage examination model, which suggests that users make judgments according to different signals in different stages.
Proceedings ArticleDOI
Incorporating Non-sequential Behavior into Click Models
TL;DR: Experimental results show that PSCM outperforms other click models in terms of both predicting click behavior (perplexity) and estimating result relevance (NDCG and user preference test).

Improving Back-Translation with Uncertainty-based Confidence Estimation
TL;DR: This work proposes to quantify the confidence of NMT model predictions based on model uncertainty, and shows that uncertainty-based confidence estimation significantly improves the performance of back-translation.

Improving Back-Translation with Uncertainty-based Confidence Estimation
TL;DR: This paper proposed to quantify the confidence of NMT model predictions based on model uncertainty, and showed that uncertainty-based confidence estimation significantly improves the performance of back-translation in Chinese-English and English-German translation tasks.
