Description
Summary:Learning to rank methods aim to learn a refined ranking model from labeled data for desired ranking performance. However, the learned model may not improve the performance on each individual query because the distributions of relevant documents among queries are diversified in document feature space. The performance of learned ranking models may be largely affected by the usefulness of document features. To generate high-quality document ranking features, we capture the local context information of individual queries from the top-ranked documents of an initial retrieval using pseudo-relevance feedback. Based on the top-ranked feedback documents, we propose an attentive semi-supervised autoencoder to refine the ranked results using an optimized ranking-oriented reconstruction loss. Furthermore, we devise the hybrid listwise query constraints to capture the characteristics of relevant documents for different queries. We evaluate the proposed ranking model on LETOR collections including OHSUMED, MQ2007 and MQ2008. Our model produces better experimental results and consistent improvements of ranking performance over baseline methods.
