reference will now be made in detail to the various exemplary embodiments of the disclosed subject matter , exemplary embodiments of which are illustrated in the accompanying drawings . the structure and corresponding method of operation of the disclosed subject matter will be described in conjunction with the detailed description of the system . the accompanying figures , where like reference numerals refer to identical or functionally similar elements throughout the separate views , further illustrate various embodiments and explain various principles and advantages all in accordance with the disclosed subject matter . for purpose of explanation and illustration , and not limitation , exemplary embodiments of methods , systems , and media to create a scored device association graph in accordance with the disclosed subject matter are shown in fig1 - 4 . while the present disclosed subject matter is described with respect to using the methods , systems , and media for creating a scored device association graph , one skilled in the art will recognize that the disclosed subject matter is not limited to the illustrative embodiments . browserapp : a single browser or application on a screen or device . a screen contains one or many browsers or applications that may request data , such as advertisements . screen : a physical device with a display ( e . g ., a desktop computer , tablet or mobile phone ). consumer : a person who can be identified by having multiple screens . according to an embodiment of the disclosed subject matter and referring to fig1 , the object represented describes a household represented by a single consumer with a single screen containing a single browser . households , consumers , and screens may contain one or many of their child elements . for example : a household could contain one or more consumers ; a consumer could have one or more screens ; and a screen could contain one or more browsers . each child element contains a score that represents the strength of association of the child element to the parent . for example , in the json ( javascript object notation ) object in fig1 , the score of 80 ( tohhscore ) represents an 80 percent probability that the consumer is indeed a member of its parent household . additionally , data elements and segments can be attached to both the consumer and household objects representing data that is acquired through consumers opting in to sharing their data for marketing purposes . the browserapp nodes have attached to them common marketing identifiers from the advertising ecosystem . these common identifiers are contained in the platformdata array . there may be one or many identifiers to the browserapp object . fig4 illustrates one embodiment for the process of attaching these common identifiers to the browserapp . according to an embodiment of the disclosed subject matter and referring to fig2 , the association between browserapps and households can be carried out in a joint fashion as follows . the ip addresses in the data warehouse 114 are grouped by ip address type ( e . g ., dsl , cable , mobile , etc .) and the properties of the ip address type are derived from the data at 112 . this includes the typical time an ip type is localized to a single router . impressions connected to a single ip address and their corresponding browserapps are extracted from the data warehouse 114 guided by the properties of the ip type . for example , if the typical time a dsl ip address is connected to single router is 30 days , that time window is used to extract data for each ip address of the dsl type . the time pattern of the appearance of new browserapps at 111 is used to calculate a score for an ip address being a household . the time pattern of impressions at 113 is used to calculate a score for the ip address being a household . the scores and properties from 111 , 112 and 113 are used to identify ip addresses likely to be a household location at 110 . the browserappids are then associated with the unique household objects they appear in fig1 . according to an embodiment of the disclosed subject matter and referring to fig3 , there are 2 representative api calls . in api call 3 . 1 , an api user requests a graph object that matches identifier “ abcd ” belonging to platform 1 . the user requests depth 3 of the graph that will return the entire group of associations as shown in fig1 . the api user in call 3 . 1 requests score 70 which will only return household , consumer , and screen objects that are thought to be highly correlated with the identifier passed in for the browserapp . in api call 3 . 2 , an api user requests the number of android devices attached to a specific segment . the return value will be an integer representing the number of android devices contained in that segment that are thought to be strongly associated with browserapp devices identified in that segment ( score 80 and above ). according to an embodiment of the disclosed subject matter and referring to fig4 , a segment provider 101 or an advertiser or publisher 102 places an iframe or pixel within their app or browser . the pixel or iframe passes an identifier for the segment plus an identifier for the browserapp to the data warehouse 103 . the information is then stored and attached to a specific browserapp along with the data and time representing the last seen view of that device . queries to the association graph can now be made using the identifier passed into the api . also in fig4 , a bidder on an exchange may buy an impression on the exchange which will then place an iframe or pixel on the browserapp that will send data back to the data warehouse storing the exchange identifier or common identifier associated with the browserapp element into the association graph along with a date and time representing the last seen . according to an embodiment of the disclosed subject matter and referring to fig5 , objects connected to a unique household are related in a hierarchical manner . one or more consumers may be related to a single household . a unique consumer may be related to one or more unique screens , possibly sharing them with other unique consumers . a unique screen may have one or more unique browserapps . but a unique browserapp can only be associated with a single unique screen . according to an embodiment of the disclosed subject matter , there are three association processes for the unique objects connected to a unique household : browserapp to screen , browserapp to consumer , and screen to consumer . the following three processes run after the identification of households and after browserapps have been associated to households . first , an association is made between browserapps to screen . in this process , various pieces of information are used to infer the existence of different screens in a household . for example , the near simultaneous appearance of impressions in different locations for two browserapps signals that they belong to different screens . as another example , browserapp snapshots typically include device wide characteristics such as operating system , software versions , and installed fonts . second , an association is made between browserapps to consumer . in this process , various pieces of information are used to infer the existence of different consumers in a household . for example , the near simultaneous appearance of impressions in different locations for two browserapps signals they belong to two different consumers . as another example , the unsupervised clustering of uris for browserapp impressions can identify distinct browsing patterns . third , an association is made between screen to consumer . in this process , using the association scores from the two previous processes ( browserapp to screen , browserapp to consumer ) we can calculate an association score from screen to consumer . the methods described herein may be implemented on a variety of communication hardware , processors and systems known by those of ordinary skill in the computing arts . the various diagrams
