| Abstract | In sponsored search auctions advertisers compete for ad slots in the search engine results page, by bidding on keywords of interest. To improve advertiser expressiveness, we augment the bidding process with conflict constraints. With such constraints, advertisers can condition their bids on the non-appearance of certain undesired ads on the results page. We study the complexity of the allocation problem in these augmented SSA and we introduce an algorithm that can efficiently allocate the ad slots to advertisers. We evaluate the algorithm run time in simulated conflict scenarios and we study the implications of the conflict constraints on search engine revenue. Our results show that the allocation problem can be solved within few tens of milliseconds and that the adoption of conflict constraints can potentially increase search engine revenue. |

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.
