摘要:
A computer-implemented method for presenting content based on information detected in real time includes: receiving first information corresponding to detection of at least attendance at a physical location; selecting, in real time with the detection, at least one winning bid based on the first information, the at least one winning bid conditioned on the first information meeting an attendance criterion; and providing at least one winning content item associated with the selected winning bid to a content presentation device at the physical location.

Methods, systems, and apparatus for allocating advertising budgets. In one aspect, a method includes receiving a set of candidate keywords specifying targeting keywords for content items. Each targeting keyword can be a phrase to be matched for a content item to be eligible to be provided in response to a content item request. For each of the targeting keywords, a probability distribution specifying likelihoods of specified user actions occurring in response to a content item is received. Based on the probability distributions, a set of final keywords with which distribution of the content items will be controlled is selected, the set of final keywords being one or more keywords for which a likelihood of a specified outcome occurring exceeds a threshold likelihood. The set of final keywords is a set which a total cost of distributing the content items is below a specified value.

Items can be reserved in advance of a future spot market sale. A reservation price can be determined for the item based on an expected spot market price required to obtain the item in the future sport market sale, a time until the spot market sale, and/or market signals. The reservation price can converge to the expected spot market price as the time of the future spot market approaches.

Methods, systems, and apparatus for content distribution. In one aspect, a method includes obtaining reservation data for a resource, the reservation data specifying a reservation period and a number of impression reservations for the reservation period; receiving, during the reservation period, content item request data specifying that the resource was requested; identifying candidate content item providers; determining an expected revenue that will be obtained by selecting one of the candidate content item providers to provide a content item providing, to a content item exchange, auction data including a reserve price; receiving positive response data specifying that the content item exchange will provide an exchange content item for a price that meets the reserve price; and in response to receiving the positive response data, selecting the exchange content item as the content item to be provided in response to receiving the content item request data.
摘要:
Described is a system and method for receiving a data stream of multi-dimensional items, collecting a sample of the data stream having a predetermined number of items and dividing the sample into a plurality of subsamples, each subsample corresponding to a single dimension of each of the predetermined number of items. A query is then executed on a particular item in at least two of the subsamples to generate data for the corresponding subsample. This data is combined into a single value.

A system, method and computer-readable medium are disclosed for identifying representative data using sketches. The method embodiment comprises generating a plurality of vectors from a data set, modifying each of the vectors of the plurality of vectors and selecting one of the plurality of generated vectors according to a comparison of a summed distance between a modified vector associated with the selected generated vector and remaining modified vectors. Modifying the generated vectors may involve reduced each generated vector to a lower dimensional vector. The summed distance then represents a summed distance between the lower dimensional vector and remaining lower dimensional vectors.
摘要:
Content item presentation slots (e.g., advertisement slots) can be grouped into a slot group so that more than one presenter (e.g., advertiser) can share a corresponding number of slots on the publisher's property over a defined time period. The presenters can be scheduled to the slots within the slot group to maximize a performance measurement (e.g., number of clicks) that each presenter realizes according to budget constraints that are defined by the presenters.
摘要:
Co-performance measurements can be determined for a plurality of content items, each co-performance measurement being associated with a corresponding content item and each co-performance measurement being a measure of the effect of the corresponding content item on the performance of one or more other content items that are presented with the corresponding content item. A set of content items can be selected for presentation to a viewer, wherein the set of content items comprises the content items that maximize a cumulative performance of the set of content items. Each content item can be assigned to a presentation position based on the co-performance measurement of each content item.
摘要:
A system, method and computer-readable medium provide for assigning sampling methods to each input stream for arbitrary query sets in a data stream management system. The method embodiment comprises splitting all query nodes in a query directed acyclic graph (DAG) having multiple parent nodes into sets of independent nodes having a single parent, computing a grouping set for every node in each set of independent nodes, reconciling each parent node with each child node in each set of independent node, reconciling between multiple child nodes that share a parent node and generating a final grouping set for at least one node describing how to sample an input stream for that node.
摘要:
Described is a system and method for receiving a signal for transmission and encoding the signal into a plurality of linear projections representing the signal. The encoding includes defining a transform matrix. The transform matrix being defined by processing the signal using a macroseparation matrix, processing the signal using a microseparation matrix and processing the signal using an estimation vector.
