Abstract: Systems and methods for building an index for matching queries and bidded terms are disclosed. The expansion of the bid-terms includes a collective expansion using graph mining techniques on a subgraph extracted from user actions on a bi-partite graph. The extracted subgraph is specific to an AdGroup (obtained using all the available context) and is personalized. The extracted subgraph can be tuned to various objectives such as head/torso/tail, specific vs generic etc. Multiple relevance measures of candidate query nodes are calculated with reference to multiple source nodes or context, and the final rankings are biased to commercial relevance using personalized random-walks.

Abstract: Methods and systems are disclosed which allow shifting inventory to fulfill guaranteed delivery advertisement contracts. Inventory may be allocated from a supply of unallocated inventory to one or more advertisers in accordance with guaranteed delivery agreements. Inventory may be reserved for the one or more advertisers from the remaining supply of unallocated inventory. Inventory may then be allocated to an additional advertiser by using unallocated inventory or shifted inventory, or a combination of unallocated inventory and shifted inventory. The shifted inventory is shifted out of the allocation for the first advertiser and the shifted inventory is replaced by the reserve inventory for the respective advertiser.

Abstract translation: 公开了允许转移库存以实现保证交货广告合同的方法和系统。 根据保证的交付协议，库存可以从未分配的库存供应分配给一个或多个广告客户。 从剩余的未分配库存供应中可能会为一个或多个广告客户预留库存。 然后可以通过使用未分配的库存或转移的库存，或未分配的库存和转移的库存的组合，将库存分配给附加的广告客户。 已转移的库存已从第一个广告客户的分配中移出，而转移的库存将被相应广告客户的备用库存替换。
