摘要:
To approximate a visual layout of a web page without rendering the page, an object tree representing elements within the page is recursively traversed to determine bounds for the width of the elements, resulting in lower bounds induced for non-leaf nodes by elements within these nodes and upper bounds induced by ancestors and siblings of nodes. For each element, the minimum required width (lower bound), the desired width were there no constraints, and the maximum available width (upper bound) based on constraints of parents are computed, and an approximate width is derived therefrom. A positioning process positions each element within its corresponding parent container by advancing a cursor according to the elements' approximate width and appropriate constraints. The element that contains the most meaningful content is determined based on the amount of weighted content of elements and their position within the page.

A method for executing multiple, cascading ad auctions, including receiving a request to deliver ads in response to a search query for display on a search results page having a plurality of ad sections; executing at least first and second sequential auctions for the plurality of ad sections by: ranking the ads in the first auction and identifying which of the ads placeable in the North section to deliver according to a first utility function that considers a relevance of the search results page with the ads placed; ranking a remainder of the ads not identified for delivery to the North section in the second auction and identifying which of the remainder of the ranked ads to deliver to a second section based on a second utility function; and delivering the ads identified by the first utility function for display in the North section and the ads identified by the second utility function for display in the second section.

Techniques are described for normalizing dynamic URLs using a hierarchical organization of a web site. Given web pages associated with a web site, an information extraction method is used to generate data structures that represent the content or structure of each of the web pages. These data structures are appended to the corresponding dynamic URLs. The modified URLs with the data structures are tokenized with the resulting tokens clustered to create a hierarchical organization. Nodes of the hierarchical organization may be merged based upon occurrence or patterns of content and structure. The merged hierarchical organization may then be pruned to remove irrelevant information and to reduce the memory footprint of the hierarchical organization. When a new dynamic URL is received, the new dynamic URL is matched to the hierarchical organization. Important parameters are taken into account and irrelevant information may be removed. Based upon the matching to the hierarchical organization, a normalized URL is returned.

Embodiments are directed towards employing long and short term historical user click propensity behaviors to adapt or filter a number of advertisements displayed and their location on a search results' page. A network device tracks a user's short and long term historical click behaviors. For a given search query for the user, a variety of candidate advertisements are selected. A normalized click-through rate (COEC) is estimated for each advertisement. The COEC and the user's short and long term click behavior, represented by User Click Propensity (UCP), is used to generate a User effective Cost Per Thousand (UeCPM) value. Candidate advertisements are filtered based on a minimum threshold value for UeCPMs. Page placement for the remaining advertisements is determined based on a user expected revenue for an advertisement determined from the UCP. Advertisements having a user expected revenue above another threshold are placed in a north page location.

A method for reducing ad impact on users in a search results page includes receiving a request to deliver ads in response to a search query for display on a search results page; receiving relevance scores for a plurality of ranked web results that are to be served to the search results page; ranking a plurality of ads identified as relevant to the search query according to a position-normalized, click-through-rate metric and bid values, wherein a predetermined number of the top-ranked ads are placeable in a plurality of North ad slots; incrementally and additively placing the placeable ads sequentially according to rank (k) in their respective North ad slots until a utility score generated by a utility function for a current iteration of ads fails to exceed a threshold value; and delivering to the search results page the ads placed in the North ad slots.

Techniques for using social networking information may include making a determination that content authored by a first party references a second party more than a specified number of times. An adjustment in affinity may be made between the first party and the second party in the social network in response to the determination. Making the adjustment in affinity may include modifying a social graph of at least the first party that is referenced by the social network in order to reflect the adjustment in affinity. Modifying the social graph includes creating a closer connection between the first party and the second party than had existed prior to the determination. In response to the adjustment in the affinity, promotion is adjusted, to the first party, of content in the social network that has a connection to the second party.
摘要:
The present invention is directed towards systems and methods for ranking and providing advertisements in a position auction. The method of the present invention comprises receiving a search query and selecting at least one keyword based upon the search query. A list containing at least one keyword based upon the search query is returned and a list comprising at least one bid corresponding to the returned list of keywords is retrieved. The search query and list comprising at least one bid are used to train an offline simulator. The offline simulator creates a model that predicts optimal scoring factors. A priority score corresponding to each bid is computed using the optimal scoring factors and used to rank the list of bids. Advertisements are then provided corresponding to a plurality of the highest ranking bids.
