A method and system for placement of graphical objects on a page to optimize the occurrence of an event associated with such objects. The graphical objects might include, for instance, advertisements on a webpage, and the event would include a user clicking on that ad. The page includes positions for receipt of the object material. Data regarding the past performance of the objects is stored and updated as new data is received. A user requests a page from a server associated with system. The server uses the performance data to derive a prioritized arrangement of the objects on the page. The server performs a calculation regarding the likelihood that an event will occur for a given object, as displayed to a particular user. The objects are arranged according to this calculation and returned to the user on the requested page. The likelihood can also be multiplied by a weighting factor and the objects arranged according to this product.

A method of determining at least one match item corresponding to a source item. A database of multiple items such as songs is created. Each song is also represented by an n-dimensional database vector in which each element corresponding to one of n musical characteristics of the song. An n-dimensional source song vector that corresponds to the musical characteristics of a source song is determined. A Distance between the source song vector and each of database song vector is calculated, each distance being a function of the differences between the n musical characteristics of the source song vector and one of source database song vector. The calculation of the distances may include the application of a weighted factor to the musical characteristics of resulting vector. A match song is selected based on the magnitude of the distance between the source song and each database songs after applying any weighted factors.

Systems and methods for scoring a domain web traffic based on DNS traffic requests received at an authoritative name server to resolve the domain name. A request to resolve the domain name is received at an authoritative name server. A counter, such as a server counter or a hit counter, for the domain name is incremented based on the received request. A score, such as a domain traffic score or a domain rank, is calculated based upon a count of the counter. Calculating the score may also include applying a weighting factor to the counters based on information about a requesting set of resolvers and other domains/websites that may be linking and driving traffic to the domain whose traffic score is being calculated. Examples of relevant set of resolvers information may include location, traffic levels, traffic type and architecture of the set of resolvers.

A generic algorithm for analysis of resource metrics. A threshold is calculated in a stack tier policy for the performance state of a metric in a virtualized process collection (VPC). Responsive to determining that the metric is a critical metric, a weighted average of all metrics in the VPC is determined. Responsive to determining that the weighted average exceeds the threshold in the stack tier policy, if the value of the metric is determined to be higher than values for all recorded metrics, the value of the metric is stored as a highest value. A weighted average performance state of all metrics is calculated as the weight property of the performance metric divided by the weight factor total. Responsive to determining that the highest value is higher than the weighted average performance state of all metrics, the highest value is used as the performance state of the VPC.
