| Abstract | Search advertising shows trends of vertical extension. Vertical ads, including product ads and local search ads, are proliferating at an ever increasing pace. They typically offer better ROI to advertisers as a result of better user engagement. However, campaigns and bids in vertical ads are not set at the keyword level. As a result, the matching between user query and ads suffers low recall rate and the match quality is heavily impacted by tail queries. In this paper, we propose an ad retrieval framework for retail vertical ads, based on query rewrite using personal history data to improve ad recall rate. To insure ad quality, we also present a relevance model for matching rewritten queries with user search intent, with a particular focus on tail queries. In addition, we designed and implemented a GPU-based system to accelerate the training of the relevance model to meet production performance constraints. Finally, we carry out extensive experiments on large-scale logs collected from Bing, and show significant gains in ad retrieval rate without compromising ad quality. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
