Abstract: A system is described for measuring web traffic relating to an offline advertising campaign. The system may include a processor and a memory. The memory may be operatively connected to the processor and may store an offline advertising campaign of an advertiser, a time period, a set of users and web traffic data. The processor may identify the offline advertising campaign, and the period of time the offline advertising campaign was available to a set of users. The processor may measure the web traffic related to the offline advertising campaign of the users during the time period.

Abstract: A facility for delivering a user segment displays an ordered set of steps making up a process, and receives user input selecting one of the displayed steps of the process. In response to receiving the user input, the facility creates a new user segment definition. The created user segment definition establishes a segment to include those users that complete the displayed process through the selected step.

Abstract: A system is described for serving an online advertisement based on an offline advertising campaign. The system may include a memory, an interface and a processor. The memory may be operatively connected to the interface and the processor and may store an offline advertising campaign of an advertiser, an advertising effect period, a set of users, and an online advertisement. The interface may be operatively connected to the memory and may be used to serve the online advertisement to the users in the set of users. The processor may be operatively connected to the memory and the interface. The processor may identify the offline advertising campaign and the advertising effect period, the period when the offline advertising campaign is capable of effecting the online behavior of the set of users. The processor may identify an online advertisement relating to the offline advertising campaign.

Abstract: Cluster- and descriptor-based recommender systems are disclosed which can, for example, scale to voluminous data. The data is generally organized into records and items. In one embodiment, a method first consolidates the data into groups, such as clusters or descriptors. The method determines a predicted vote for a particular record and a particular item, using a similarity scoring approach, such as a likelihood similarity approach, or a correlation similarity approach, based on the groups. The predicted vote can then be output.
