Determining targeting information based on a predictive targeting model

Abstract

A targeting system based on a predictive targeting model based on observed behavioral data including visit data, user profile and/or survey data, and geographic features associated with a geographic region. The predictive targeting model analyzes the observed behavioral data and the geographic features data to predict conversion rates for every cell in a square grid of predefined size on the geographic region. The conversion rate of a cell indicates a likelihood that any random user in that cell will perform a targeted behavior.

Description

BACKGROUND

As the popularity of mobile devices has soared among consumers worldwide, the potential for targeting advertising content to users of mobile devices has also increased. For example, advertisers can obtain information about a current location a user of a mobile device and use that information along with information about nearby businesses to send targeted advertisements to the user's mobile device. By way of another example, advertisers can also deliver a specific advertisement to a mobile device of any user who comes within a certain radius of a point of interest.

DETAILED DESCRIPTION

Overview

Embodiments of the present disclosure include a system and method of determining targeting information based on a predictive targeting model (hereinafter the “targeting system”). The targeting model is based on observed behavioral data including visit data, user profile data and/or survey data, and geographic features associated with a geographic region. The targeting model predicts a conversion rate or likelihood that any random user in a small geographic area within the geographic region will perform a targeted behavior. The latitude and longitude coordinates of at least some of the geographic areas within the geographic region that are associated with high conversion rates are then provided by the targeting system as targeting information to advertisers, publishers and/or advertisement networks for use in targeting advertisements to customers in those locations. In some embodiments, instead of or in addition to the latitude and longitude coordinates of the locations with high conversion rates, the targeting system can identify one or more unique identifiers of the users in those locations with high conversion rates. Advertisers and publishers can then target against users with matching the unique identifiers, where those identifiers may lack any personally identifying information.

In some embodiments, location data collected from a panel of users (“panelists”) can provide information about the places the panelists visited, and the timing and duration of such visits. Based on the place visit data, information about where a panelist's home location is, where the panelist's work location is, which grocery store the panelist visits regularly, and so on can be inferred. Moreover, user profile data can provide information about age, gender, ethnicity and/or other attributes of the panelists, while survey data can provide information about preferences of the panelists. The behavioral information can be projected onto a geographic region sub-divided into geographic units or cells, with each cell having a set of geographic features. The predictive targeting model can then take into account the behavioral information projected onto the cells to identify opportunities for advertisers and publishers for targeting advertisements.

For example, consider a brand (e.g., 24 Hour Fitness) that wants to know where its potential customers are in a geographic area (e.g., Washington State) in order to target advertisements against those locations. The targeting system can analyze the behavioral data of users to identify the places the users visited and geographic feature data associated with the geographic area. The targeting system can then use the targeting model to determine that users who go to 24 Hour Fitness (“24 Hour Fitness user group”) are more likely to go to Jamba Juice compared to the overall population. Then the locations of Jamba Juice can be used for target ads related to 24 Hour Fitness because the users who live, work or visit those locations have a higher affinity for 24 Hour Fitness. Thus, rather than waiting until a user is in proximity to a 24 Hour Fitness to send an advertisement to the user's device, the targeting system enables a publisher or an advertiser to target advertisements against the locations that have a high affinity for 24 Hour Fitness regardless of whether the user is close to a 24 Hour Fitness or far away from it.

In some embodiments, the targeting model is not just based on which businesses users visited, but also a category of each business. For example, the targeting model can take into account not just Jamba Juice, but also other businesses in the beverage category that are visited by the 24 Hour Fitness user group. In some embodiments, the affinities are not necessarily with respect to businesses and/or businesses in the same category, but also demographics and/or other features of the geographic area. For example, in addition the 24 Hour Fitness user group having an affinity to Jamba Juice, the user group may also skew male. The targeting model can take into account demographics of the geographic area to identify cells that have a greater male population than female as being locations at which advertisements related to 24 Hour Fitness should be served. By way of another example, if an advertiser wants to target 13-17 year olds for a new animated feature, the targeting model would consider users that belong to the targeted age group and visits performed by the targeted age group users to identify locations against which advertisements related to the new animated feature can be targeted. In some embodiments, panelists can be asked survey questions such as “Do you like animated movies?” The targeting model would then consider users in the targeted age group that responded “yes” to the survey question and the visits performed by those users to identify locations that can be targeted against for advertisements related to the animated feature.

In some embodiments, a targeting model can also have a temporal component. For example, consider a targeted behavior of visiting a Walmart store in the morning. The targeting model would take into account place visits of users in the morning hours of 9 am to 12 noon to identify locations in a geographic region where users are likely to visit the Walmart store in the morning.

In some embodiments, the targeting model can be a look-alike model that enables advertisers to target users who look like their established or known customers. For example, the targeting model can be used to identify locations where customers who look like the people who go to 24 Hour Fitness and who are likely to sign up for a new membership are. To implement the look-alike model, the panelists can be segmented in two groups, the first group including panelists who have been to a gym in the last 30 days and the second group including panelists who have not. The behavior of the second group is considered by the targeting model as the first group of panelists likely already has a gym membership. The targeting model can then use the behavior of the second group of users to identify locations that have high affinity for gyms and/or users who are likely to sign up for a new gym membership.

Various embodiments and implementations of the targeting system will now be described. The following description provides specific details for a thorough understanding and an enabling description of these embodiments and implementations. One skilled in the art will understand, however, that the embodiments and implementations may be practiced without many of these details. Additionally, some well-known structures or functions may not be shown or described in detail, so as to avoid unnecessarily obscuring the relevant description of the various embodiments and implementations. The terminology used in the description presented below is intended to be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific embodiments and implementations of the targeting system.

Suitable System

The targeting system can be implemented in a suitable computing environment 100 illustrated in FIG. 1. Aspects, embodiments and implementations of the targeting system will be described in the general context of computer-executable instructions, such as routines executed by a general-purpose computer, a personal computer, a server, or other computing systems. The targeting system can also be embodied in a special-purpose computer or data processor that is specifically programmed, configured, or constructed to perform one or more of the computer-executable instructions explained in detail herein. Indeed, the terms “computer” and “computing device,” as used generally herein, refer to devices that have a processor and non-transitory memory, like any of the above devices, as well as any data processor or any device capable of communicating with a network. Data processors include programmable general-purpose or special-purpose microprocessors, programmable controllers, application-specific integrated circuits (ASICs), programmable logic devices (PLDs), or the like, or a combination of such devices. Computer-executable instructions may be stored in memory, such as random access memory (RAM), read-only memory (ROM), flash memory, or the like, or a combination of such components. Computer-executable instructions may also be stored in one or more storage devices, such as magnetic or optical-based disks, flash memory devices, or any other type of non-volatile storage medium or non-transitory medium for data. Computer-executable instructions may include one or more program modules, which include routines, programs, objects, components, data structures, and so on that perform particular tasks or implement particular abstract data types.

Embodiments of the targeting system can be implemented in distributed computing environments, where tasks or modules are performed by remote processing devices, which are linked through a communications network, such as a Local Area Network (“LAN”), Wide Area Network (“WAN”), or the Internet. In a distributed computing environment, program modules or subroutines may be located in both local and remote memory storage devices. Aspects of the targeting system described herein may be stored or distributed on tangible, non-transitory computer-readable media, including magnetic and optically readable and removable computer discs, stored in firmware in chips (e.g., EEPROM chips), an array of devices (e.g., Redundant Array of independent Disks (RAID)), solid state memory devices (e.g., solid state drives (SSD), Universal Serial Bus (USB)), and/or the like. Alternatively, aspects of the targeting system may be distributed electronically over the Internet or over other networks (including wireless networks). Those skilled in the relevant art will recognize that portions of the targeting system may reside on one or more server computers, while corresponding portions reside on a client computer. Data structures and transmission of data particular to aspects of the targeting system are also encompassed within the scope of the present disclosure.

A targeting system 115 embodied in a targeting server 120 can operate in the example environment 100 illustrated in FIG. 1. The targeting server 120 can be coupled to one or more databases and/or database tables represented as a database 125. The environment 100 includes panelist devices 150, which can be devices of panelists of the targeting system that report location and other information to the targeting system 115 and/or an inference pipeline system 130. The interference pipeline system 130 is shown as including an analytics server 135 and a database 140. The panelist devices 150 can be any type of client device capable of measuring and reporting its location data. Typically, a client application is installed on a panelist device 150 to facilitate the location data collection and reporting. The inference pipeline system 130 and the data collection system are described in detail in related application Ser. Nos. 13/405,182 and 13/405,190, both filed on Feb. 12, 2012, which are expressly incorporated by reference herein.

The environment 100 can also include one or more advertisers 105 (or content providers in general) that wish to provide advertisements or other non-promotional content to user devices 145 of users for consumption. Typically, advertisers 105 engage publishers 110 to run advertisement (“ad”) campaigns. The advertisers 105 and the publishers 110 can be computing systems in the form of one or more servers. User devices 145 can include any computing devices, such as but not limited to: a desktop computer, a laptop computer, a tablet, a mobile device or a feature phone. In some embodiments, user devices 145 can also include a television, a radio or any other electronic communication media through which content can be delivered to users for consumption. In some embodiments, the environment 100 can also include print media such as newspapers, publications, or the like. The user devices 145, via their network interlaces, connect to and/or communicate with networks 125, either directly or via wireless routers or cell towers. Networks 125 can include wired and wireless, private networks and public networks (e.g., the Internet). Network interfaces employ connection protocols such as direct connect, Ethernet, wireless connection such as IEEE 802.11a-n/ac, and the like to connect to networks 125. Some client devices may be equipped with transceiver circuitry to handle radio communications to wirelessly communicate with nearby cell towers or base stations using wireless mobile telephone standards, such as Global System for Mobile Communications (GSM), CDMA (Code Division Multiple Access), General Packet Radio Service (GPRS), and/or the like.

As illustrated, the publishers 110 can communicate with the targeting server 120 via the networks 125 to request targeting information for ad campaigns of advertisers 105. As described before, the targeting information can be latitude/longitude coordinates of locations having high conversion rates and/or one or more unique identifiers of users that are more likely to engage in a targeted behavior. The publishers 110 can then use the targeting information to target ads to user devices 145 of users.

FIG. 2 is a block diagram illustrating an overview of running an advertisement campaign using targeting information provided by the targeting system.

As illustrated in the diagram 200 an adve1iiser 105 can engage a publisher 110 to run an ad campaign 220. Generally, the ad campaign 120 can have one or more criteria that dictate how the ads are to be delivered (e.g., on web, mobile web, mobile applications), in what formats and whether the ads should be geo-targeted (e.g., country, region, metro area, city, postal code, latitude/longitude coordinates), for example. In accordance with the present disclosure the publisher 110 can provide one or more targeting criteria 225 for the ad campaign 120 to the targeting system 115. The targeting system 115 can collect behavioral data 174 collected from panelists 150 and extract geographic features from places and census data. The targeting system 115 can utilize a machine learning algorithm (e.g., based on a supervised learning model) to train a targeting model 210 using observed conversion rates determined from a random sample of the behavioral data 174 and the geographic features of geographic units (e.g., cells) and use the trained targeting model 210 to predict conversion rates for geographic units. The conversion rates for geographic units can then be further processed and ranked to identify a portion of the location coordinates 230 with the highest conversion rates that can be used for targeting the ad campaign. In some embodiments, instead of or in addition to the location coordinates, user profiles or unique identifiers can be provided as targeting information to the publisher 110, including anonymous identifiers that lack any personally identifiable information (“PII”), e.g. where the publisher has access to only identifier.

The publisher 110 can then run the ad campaign 220 based on the targeting information. For example, the publisher can identify user devices 205A-D as being located at the targeting location coordinates 230 and can then send ads 235 to these user devices 205, and receive impressions 240 from the user devices 205. By way of another example, the publisher 110 can identify the users 205 as having user profiles matching the targeting user profiles 230 and can send ads to 235 to the user devices 205A-D of the users 205 (even though the publisher lacks any specific PII for each user).

Example Processing

FIG. 3 is a block diagram illustrating generation of targeting information based on an analysis of behavioral data, place data and census data using a targeting model to predict a conversion rate of each cell in a grid on a geographic region.

The targeting system 115 uses observed behavioral data 174 in determining targeting information. The observed behavioral data 174 can include place visit data 302 that links a user to a place at an instance of time. For example, place visit data 302 can indicate that a user visited a Walmart store in Shoreline, Wash. on Mar. 2, 2012 from 9 am-11:30 am. The observed behavioral data 174 can also include demographic profile data 306. For example, the demographic profile data 306 can indicate that the user is a male and his ethnicity is Hispanic. The observed behavioral data 174 can also include survey data 308 (e.g., how the user answered a specific survey question). The observed behavioral data 174 can be collected from the panelists of the targeting system 115 and can be organized and processed before being used as input data to the targeting model 155.

The targeting system 115 can also use place data 310 and census data 315. The place data 310 can include information about places (e.g., latitude/longitude coordinates of places, place names, business categories, and/or the like). The census data 315 can include but are not limited to: population density, proportion of population at various income buckets, proportion of married individuals, proportion of males at various age buckets, proportion of females at various age buckets, proportion of males at various education buckets, proportion of females at various education buckets, and/or the like. The targeting system 115 can extract features or distinct attributes from the place data 310 and/or census data 315 that can quantitatively describe each cell (e.g., cells 325) in a geographic region 320. Generally, a sample of users and their corresponding behavioral data and feature data are used in training the predictive targeting model 155, which when applied to the overall set of behavioral data 174 and the feature data, can output a predicted conversion rate 160 for each cell (e.g., cells 325) in the geographic region 320 as illustrated. The predicted conversion rate 160 for each cell can then be used to identify targeting location coordinates 330 and/or targeting user profiles or unique user identifiers 335.

Example Programming Modules

FIG. 4 is a block diagram illustrating example modules of a targeting server 120 of the targeting system 115. In some embodiments, the targeting server 120 can include various computer-executable program modules stored in a memory 402. Examples of the program modules can include a behavior data analyzer 405, a geographic features data generator 410, a geographic features data labeling module 415, a model training module 420 that includes a training dataset generator 422 for building a predictive model 425, a model application engine 430, a reporting module 432 and/or a cell aggregator 435. The targeting server 120 can also include additional modules (e.g., communication modules, user interface modules and so on) that have not been described herein.

In some embodiments, the targeting server 120 receives one or more targeting criteria 404 from a client (e.g., a publisher, an advertiser) as input. Such targeting criteria can include a targeting behavior (e.g., target customers who go to Walmart), a demographic criterion (e.g., males), a geographic region of interest (e.g., a state, a country or any arbitrary geographic area), etc. The targeting server 120 via the geographic features data generator 410, can divide the geographic area of interest using a grid into cells (e.g., 250 m by 250 m square cell) and generate feature data for each cell. The feature data can include, for example, a total number of places, distances to nearby businesses of particular brands and distances to nearby categories of businesses, demographic features (e.g., percent of males, percent of females, percent of different ethnicities) and/or the like and can be stored in a database table in the database 125. While generally shown and described as using a two-dimensional grid, the system may also employ a three dimensional grid. Such a grid can be useful in dense urban locations, such as Hong Kong, where the system benefits from understanding which floor of a high-rise building a user visits, and the business on that floor being visited. In such an embodiment, the system uses not only latitude and longitude data, but also altitude data.

In addition to the feature data, targeting server 120 also considers observed behavioral data stored in a table in the database 125. The behavior data analyzer 405 can select a set of users for the targeting analysis. Normally, the set of users can include all the panelists of the targeting system. The panelists are users of the targeting system from whom geolocation data is collected. A data collection system can obtain user information, including location data, collected directly from the panelists. The data collection system obtains and validates location data from the panelists. The user information collected by the data collection system includes, for example, latitude, longitude, altitude determinations, sensor data (e.g., compass/bearing data, accelerometer or gyroscope measurements), user agent identifying information (e.g., device identifier, device name/model, operating system name/version), and other information that can be used to identify a panelist's location and activity. Additional details on the data collection system can be found in related application Ser. Nos. 13/405,182 and 13/405,190 both filed on Feb. 12, 2012 which are expressly incorporated by reference herein. In some embodiments, the set of users can include panelists matching one or more criteria. For example, the set of users can be users associated with a demographic feature or users who were asked a specific survey question. This set of users forms a global user set or group. The behavior data analyzer 405 then selects users who match a profile and/or a targeted behavior (e.g., answered a survey question a specific way) from the global user set to form a behavior matched user set. Referring to FIG. 5, the behavior match user set 510 is a subset of the global user set 505. The behavior data analyzer 405 can also identify all visits performed by the global user set as a global visit set and a subset of the global visit set that matches the targeted behavior (e.g., visiting a Walmart store) and performed by users in the behavior match visit set as a behavior match visit set. As illustrated in FIG. 5, the behavior match visit set 520 is a subset of the global visit set 515.

The geographic features data labeling module 415 utilizes information relating to the global visit set and the behavior matched visit set to determine a behavior match metric for each user in the behavior matched user set. The behavior match metric for a user defines a total number of days with each at least one behavior match visit by the user. As illustrated in FIG. 5, the behavior match metric can be calculated by grouping the behavior match visit set by user id 525 and by day 532. A probability of at least one behavior match visit 530 for each day is calculated and the number of days with a behavior match visit is summed to obtain the total behavior match visit metric 535. A value of the behavior match metric corresponding to a user from the behavior matched user set can then be assigned to a key formed by the tuple (cell id, user id) corresponding to all the visits to various places by the global user set. For example, if the value of a behavior match metric of user “A” is 10, then that value can get mapped on to each visit by user “A” in the following manner:

(1) user A visited “Walmart” in cell id “2”→key: (2, A)=10

(2) user A visited “Target” in cell id “1”→key (1, A)=10

(3) user A visited “Whole Foods” in cell id “5”→key (5, A)=10

The geographic features data labeling module 415 can then join the key-value pair obtained from the observed behavioral data with the geographic feature data (generated by the geographic features data generator 410) using the cell id to label the geographic features data with the behavior matched metric. The result is a labeled feature vector table, with the key: (cell id, user id, [feature vector]) and the value: behavior matched metric. This labeled feature vector table can be stored in a database table of the database 125. This has the effect of layering the observed behavioral information on to the cells so that all of the cells in which a user was observed get labeled with a prediction of the probability that the user will perform the targeted behavior.

The training dataset generator 422 of the model training module can generate a training data set for training a two-level predictive model 425 to predict a conversion rate for each cell, which is the probability that a random user observed in a cell will perform the targeted behavior. The training dataset generator 422 can take a random sampling of labeled feature vectors from the labeled feature vector table for the training. In some embodiments, prior to sampling, the training dataset generator 422 can perform a thresholding to exclude certain labeled feature vectors (e.g., labeled feature vectors with a place distance feature that exceeds 100 km) from the initial dataset.

At the first level, the model training module 420 can use the labeled feature data from the labeled feature vector table, including the observed behavior match metric, to train a model to predict a value of the observed behavior match metric which corresponds to a visit probability. At the second level, the system trains a statistical model (e.g., a linear regression model) using an observed conversion rate of a cell to predict a conversion rate of the cell for a given visit probability and in some embodiments, a geo-fence feature (e.g., the distance from Walmart or radius around Walmart). The model training module 420 can calculate the observed conversion rate as the average value of the behavior match metric over all users observed in a given cell in the training dataset. The statistical model can thus predict the average number of times the targeted behavior was performed by users observed in a given cell.

The model application engine 430 can apply the two-level predictive model 425 to a set of feature data (e.g., the full set of feature data) to generate a predicted conversion rate for the cell. The model application engine 430 can apply the first level of the model 425 to predict visit probabilities and the second level of the model 425 to predict the conversation rates. In some embodiments, the model application engine 430 can rank the cells based on conversion rates and select the top n number or x percent of cells as cells with high affinity for the targeted behavior. The reporting module 432 can then report locations (e.g., latitude and longitude coordinates) corresponding to the high affinity cells as targeting information 440. In some embodiments, instead of or in addition to the locations corresponding to the high affinity cells, one or more unique identifiers of users observed in these high affinity cells can be reported as targeting information 440. In some embodiments, the model application engine 430 can combine conversion rates with predictions of number of impressions served per cell (e.g., via another model) to generate a combined score. The cells can then be ranked based on the combined score and the top performing cell coordinates can be provided as targeting information 440. In some embodiments, the model training module 420 and the model application engine 430 can include or use only the first level and pass the predicted visit probabilities to the cell aggregator 435.

In some embodiments, the cell aggregator 435 can aggregate the predicted conversion rates to allow for a targeting area that is larger than a cell. The cell aggregator 435 can calculate an aggregate conversion rate of each cell by summing conversion rates of the cell and neighboring cells within a pre-defined distance from the cell. The cell aggregator 435 can retain only those cells with the highest aggregate conversion rates within a smaller radius. The reporting module 432 can then report locations corresponding to the retained cells as targeting information 440.

As described above, location data (e.g., 2-dimensional or 3-dimensional location data) can be used for indexing targeting predictions. In some embodiments, in addition to the location data, user agent identifying information, such as but not limited to operating system name/version, device name, model and/or identifier, and/or the like, can be used for indexing targeting predictions.

FIG. 6A is a logic flow diagram illustrating an example method of generating geographic features data by the targeting system.

In some embodiments, the targeting system 115 generates a geographic feature set that includes a list of vectors of feature data from place data 605 and/or census data 635. The place data 605 and the census data 635 can be stored in the database 125. Each row in the geographic feature set can correspond to a cell (e.g., 0.005 degree×0.005 degree section on the map of the globe) and each column in a vector includes a feature extracted from the place data and/or the census data.

For each cell, the targeting system 115 can retrieve places that are within a predetermined distance from the cell (e.g., ˜750 meters from the center of the cell) at block 610. The targeting system 115 can then extract nearby place features from the resulting data set at block 620. Examples of nearby features that can be extracted can include, but are not limited to:

1. Total number of places

2. Total number of places from each business category (e.g., the number of coffee shops within 750 meters of the cell)

3. Ratio of total number of places from each business category to total number of places (“category proportion”)

At block 615, the targeting system can extract, for each cell, place distance features by calculating the distance to the nearest place of each brand and business category. This calculation can be an expensive process and some of the computational cost of performing this calculation can be reduced by using the following example methodology:

1. For each place, map or assign the place to all cells that are within 100 km of the place.

2a. For each of these cells, calculate the distance from the center of the cell to the place.

2b. Emit or generate a key-value pair. The key is the tuple (cell id, business id, category id) and the value is the calculated distance from 2a. The business id identifies a brand (e.g., McDonald's or Starbucks) and the category id identifies a type of business (e.g., a cafe or a grocery store).3. For each (cell id, business id, category id) tuple, find the minimum distance from the cell (e.g., center of the cell) to the business id, and emit the key-value pair (cell id, (business id, category id, minimum distance)).4. For each cell, calculate the following features:

4a. Minimum distance to each business id

4b. Minimum distance to each category id

For example, if there are three business ids (McDonald's, KFC and Walmart) associated with a cell id, after step 4, a following example row can be generated:

(cell id, mcdonalds_min_distance, Walmart_min_distance, kfc_min_distance, fast_food_min_distance, retail_min_distance)

At block 640, the targeting system 115 can retrieve census data 635 and calculate demographic features. The census data 635 can include, for example, a block group, census tract, county census tables and/or the like. Each census aggregation region can have its geographic shape associated with it. The targeting system 115 can calculate demographic features using the following example methodology:

1. For each census region, calculate a vector of features from the census table:

1a. population density

1b. proportion of population at various income buckets

1c. proportion of married individuals

1d. proportion of males at various age buckets

1e. proportion of females at various age buckets

1f. proportion of males at various education buckets

1g. proportion of females at various education buckets

2. For each cell inside each census region, generate a key-value pair. The key is the cell id. The value is the tuple (aggregation size, feature vector).

3. For each cell, find the feature vector associated with the smallest aggregation size and generate the key value pair (cell id, feature vector).

The nearby place features (from block 620), the place distance features (from block 615) and the demographic features (from block 640) are then merged together at block 650 to obtain a set of geographic features 655.

FIG. 6B is a logic flow diagram illustrating an example method of generating predicted conversion rate per cell by the targeting system.

In some embodiments, the targeting system 115 receives user visits data 660, user profiles 662 and/or survey data 664. In some embodiments, the targeting system 115 can consider all the users of the targeting system for analysis. Alternatively, at block 666, the targeting system can filter users based on one or more criteria. The one or more criteria can include, for example, survey data 664 and/or user profile data 662 (e.g., users matching a demographic criterion). The set of users that match the filter criteria from the global user group or set.

At block 668, the targeting system 115 can tag users that match a targeted behavior. The tagged users then form the behavior matched user group or set. In this instance, the targeted behavior can be unrelated to store or place visits and may be related to, for example, survey data 664. For example if a user answered a specific survey question a specific way, then that user can be in the behavior matched user group. In some embodiments, if only place visit constraints are specified as a targeted behavior, then the functionality of block 668 is optional because the user group would be the same the global user group.

At block 670, the targeting system 115 filters the user visits data 660 using the global user group determined from block 666 to obtain a set of all visits performed by each user in the global user group (“global visit set”). At block 672, the targeting system 115 tags the visits in the global visit set that match a targeted behavior performed by each user in the behavior match user set. This subset of the global visit set is the behavior match visit set. For example, if the targeted behavior is visiting a Walmart, all visits with a high probability of being at Walmart can be part of the behavior match visit set.

At block 674, the targeting system 115 labels geographic features 655. The following example methodology can be used to label the geographic features 655.

1. Grouping the behavior match visit set by user and by day. For each day, calculate the probability of at least one behavior match visit. Sum this value across days to get a total number of days with a behavior match visit (“total behavior match visits”).

2. For each visit in the global visit set, generate a key-value pair. The key can be the tuple (cell id, user id) and the value can be the user's total behavior match visits calculated in (1). If a user has no visits in the behavior match visit set, this value will be 0.3. Join the key-value pairs in (2) with the geographic features 655 by cell id.

Each key-value pair is a row in a labeled feature vector table and the label is the total behavior match visits value.

At block 676, the targeting system 115 trains statistical models to obtain trained models 678. To train the statistical models, a training data set is first selected from a random sample of users and their corresponding behaviors and features. The sampled data set is then used for training the two-level statistical model to predict a conversion rate for each cell.

In the first level, based on the geographic feature data and the total behavior match visits (observed), a classifier (e.g., Random Forest Classifier) is used to predict whether the total behavior match visits is non-zero. This classification can be performed as a non-linear feature extraction step to combine the high-dimensional geographic feature vectors (e.g., a large number of features) into a single number, i.e., the visit probability, that is smaller than the original feature set but retains most of its characteristics.

In the second level, the visit probability and in some cases a geo-fence feature can be used to train a linear regression model to predict the conversion rate of a given cell. In some embodiments, the geo-fence feature can be a log-transformed distance to a target location. To train this regression model, the observed conversion rate is computed. In some embodiments, the observed conversion rate can be calculated as the average value of total behavior match visits over all users observed in a cell as seen in the sampled training data. The visit probability and geo-fence feature are then regressed on to these observed conversion rates.

In some embodiments, the targeting system 115 can apply the trained models 678 to each cell in the full geographic feature set at block 680 to generate a predicted conversion rate for each cell 684. This can be done by sequentially applying the first and second levels of the model to obtain the predicted visit probabilities and conversion rates, respectively.

In some embodiments, the targeting system 115 can aggregate cells at block 682. Aggregating the cells can include aggregating the predicted conversion rates to allow for larger targeting radii. In some embodiments, the targeting system 115 can calculate the aggregated conversion rate at each cell by considering every cell within a specified distance (e.g., number of meters). The targeted system can then retain cells with the highest aggregated conversion rate or score within a smaller radius.

FIG. 7 is a logic flow diagram illustrating an example method of identifying targeting information based on targeting criteria.

As illustrated, at block 705, the targeting system receives targeting criteria. In some embodiments, the targeting criteria can include a targeted behavior and a geographic region. The targeting criteria can be received from an advertiser, a publisher or any other entity that desires to identify people and/or places that have a high propensity to perform the targeted behavior. The targeted behavior can be any behavior of interest, for example, visiting a store or signing up for an event. In some embodiments, the targeting criteria can also include information about demographic profiles and/or survey data. For example, an advertiser may be interested in knowing where women in the age group 40-50 that have a high affinity for gyms may be located. The targeting system 115 can then consider the age group and gender of the panelists along with visits to gyms to predict those locations. The geographic region can be any region of interest (e.g., the USA, Washington, North West).

At block 710, the targeting system 115 can segment the geographic region using a grid into cells. Each cell has a cell identifier. At block 715, the targeting system 115 can receive or retrieve behavioral information associated with users. The behavioral information can include time-stamped place visit data corresponding to places visited by the users. At block 720, the targeting system 115 can calculate a behavior match metric for each cell based on the behavioral information. At block 725, the targeting system 115 can receive or retrieve feature data for each cell. The feature data can be generated using a separate process. The targeting system 116 can label the feature data for each cell using the corresponding behavior match metric to obtain labeled feature data at block 730. A set of the labeled feature data can then be used by the targeting system 115 at block 735 to train a model for predicting a conversion rate for each cell. At block 740, after the model has been trained, a set of the feature data (e.g., the unlabeled feature data) can be analyzed by the trained model to predict a conversion rate of each cell. At block 745, the targeting system 115 can identify targeting information based on the conversion rates of the cells. The targeting information can be in the form of people (e.g., unique identifiers or profile characteristics of users in cells with high conversion rates), places (e.g., location coordinates of cells with high conversion rates) or both in various embodiments.

FIG. 8 is a logic flow diagram illustrating an example method of identifying locations or users that are likely to convert, based on a particular campaign.

The targeting system 115, in some embodiments, gathers, receives or retrieves behavioral data at block 805. At block 810, the targeting system 115 receives, gathers or retrieves sets of attributes associated with an array of locations in a geographic region. Each set of attribute can be a high dimensional data (e.g., 2000 or more attributes or features). The targeting system 115 can process the gathered data to identify at least one of locations (block 815) or users (820) that are likely to convert, based on a particular campaign. In some embodiments, both locations and users can be identified and each, alone or in combination, can be used to target promotional content or non-promotional content associated with the particular campaign (or similar campaign) to other users at block 825.

In some embodiments, the targeting system 115 can identify a set of users associated with a targeted behavior and/or a targeting model using an example method illustrated in FIG. 9.

Referring to FIG. 9, the targeting system 115 can build a set of targeting models (e.g., one for each of the top 30 businesses and 20 categories) at block 902. At block 904, the targeting system 115 can normalize the set of targeting models. In some embodiments, normalizing can include calculating a mean (or another statistical measure) of predicted conversion rates for each model and using the mean to calculate, for each cell, a normalized score. The normalized score, in some embodiments, can be calculated as a ratio of a conversion rate of the cell and the mean conversion rate. At block 906, the targeting system 115 can calculate a score threshold. The score threshold, in some embodiments, can be calculated by determining the N percentile (e.g., 95^th, 98^th) normalized score across the full set of models. At block 908, the targeting system can receive or gather data over a period of time (e.g., 1 week, 1 month). The gathered data can include, for example, a user identifier, a coordinate, and a timestamp. The gathered data can be mapped to corresponding cell ids based on the coordinates at block 910. At block 912, the targeting system 115 can group the data by cell id and generate a table of data at block 914. The process for generating the table of data can include, determining, for each cell id, and for each of the normalized models (each having a model id) associated with the cell id, a normalized score for the model id and generating a user id, model id, a normalized score and a timestamp. For each user id 916 in the table of data, the targeting system 115 can determine if the user has been observed on more than a threshold number of days at decision block 918. If false, the targeting system 115 evaluates the next user id at block 940. If true, the targeting system 115 can calculate, for each model id 920 associated with the user id, a mean normalized score at block 922. At decision block 934, the targeting system 115 can if the mean normalized score is greater than the score threshold (from block 906). If true, the targeting system 115 can tag the user id with the model id at block 936. If another model id is associated with the user id as determined at decision block 938, targeting system 115 can repeat the process with the next model id 942, otherwise the next user id 940, if available, can be evaluated. In some embodiments, user profiles or unique identifiers associated with the identified user ids that are tagged with a particular model id can be provided as targeting information to a publisher associated with the model id.
