Abstract: An improved system and method for forecasting an inventory of online advertisement impressions for targeting profiles of attributes is provided. An index of advertisement impressions on display advertising properties may be built for a targeting profile of attributes from forecasted impression pools. Impression pools of advertisements sharing the same attributes and trend forecast data for web pages and advertisement placements on the web pages may be integrated to generate the forecasted impression pools. An index of several index tables may be generated from forecasted impression pools. A query may be submitted to obtain an inventory forecast of advertisement impressions for targeting profiles of attributes and the index may be searched to match forecasted impression pools for the targeted profile of attributes. Then the inventory forecast of advertisement impressions on display advertising properties may be returned as query results for the targeting profile of attributes.

Abstract: An e-learning system that provides a customized e-learning experience for a user. Information is received from a user identifying the user's learning objectives. Based upon the user's objectives, a study plan that is customized for the user is developed. The study plan may comprise one or more course units that the user can access through a server using a client system used by the user. User activity is monitored, including the user's activity within the e-learning system and outside the e-learning system. Information is recorded regarding the user's progress and performance. This information is used to modify the study plan, as appropriate for the user.

Abstract: A method and system for allocating inventory in an Internet environment is provided. A method employed by the system may include generating several inventory pools, where each inventory pool represents a number of impressions deliverable to different groups of users characterized by attributes. Impressions deliverable to users represented by each inventory pool may be allocated to each inventory pool. Impressions that correspond to multiple pools may be distributed between the multiple pools. The inventory pools may be stored to a database. Afterwards, and order may be received. The order may include parameters that define an audience and a number of impressions. The number of impressions in the order may be allocated from pools in the database.

Abstract: A method and system for allocating inventory in an Internet environment is provided. A method employed by the system may include generating samples of representatives that represent impression inventory, where each sample represents a number of users to which impressions are deliverable. An order may be received. The order may include a number of impressions to book and target audience information. A cushion of impressions needed to guarantee delivery of the number of impressions ordered may be determined. The number of impressions ordered plus the cushion may be allocated from the samples. A contract including the target audience information, the number of impressions, and the cushion may be stored to a database.

Abstract: A method and system for allocating inventory in an Internet environment is provided. A method employed by the system may include generating an inventory pool that represents a number of impressions deliverable to all users, then determining, from multiple past orders for booking impressions, a hierarchy of parameters utilized to target users and a number of impressions deliverable to users characterized by the parameters. The inventory pool may then be partitioned into multiple inventory pools according to the hierarchy, where each inventory pool represents a number of impressions deliverable to users characterized by parameters associated with the inventory pool. The hierarchy of pools may then be stored to a database.

Abstract: A method and system for allocating inventory in an Internet environment is provided. A method employed by the system may include generating multiple top-tier inventory pools and bottom-tier inventory pools that represent impression inventory. Each top-tier pool may represent the combined number of impressions represented by one or more bottom-tier pools. Each top-tier and bottom-tier inventory pool may represent a number of impressions deliverable to users characterized by attributes. Top-tier and bottom-tier inventory pools may be stored to a database. An order for booking impression from the plurality of inventory pools may be received. The order may include parameters that define an audience and a number of impressions. The impressions order may be allocated from top-tier inventory pools when the impressions ordered are entirely represented by top-tier inventory pools. Otherwise the impressions are allocated from bottom-tier inventory pools.

Abstract: A method for processing data on a distributed computing environment is provided. Input data that is to be processed may be stored on an input storage module. Mapper code can be loaded onto a map module and executed. The mapper code can load a mapper executable file onto the map module from a central storage unit and instantiate the mapper executable file. The mapper code, then, can pass the input data to the mapper executable file. The mapper executable file can generate mapped data based on the input data and pass the mapped data back to the mapper code.

A query may be submitted to obtain an inventory forecast of advertisement impressions for targeting profiles of attributes and the index may be searched to match forecasted impression pools for the targeted profile of attributes. Then the inventory forecast of advertisement impressions on display advertising properties may be returned as query results for the targeting profile of attributes.
