Abstract: A processor is configured to execute an event-driven program along a plurality of execution paths. Each of the plurality of execution paths is determined by randomly chosen outcomes at non-deterministic points along the plurality of execution paths. A memory is configured to store values of properties of the event-driven code in response to executing the event-driven program along the plurality of execution paths. The processor is also configured to infer normal ranges of the properties of the event-driven program based on the values stored in the memory.

Abstract: A method for deriving a composite tie metric for an edge between nodes of a telecommunication call graph includes receiving descriptive data with original values for descriptive attributes associated with a telecommunication call graph formed by edges between nodes. Each edge relates to two nodes. Each original value relates to an edge and a descriptive attribute forming an edge-attribute pair for the corresponding original value. The descriptive data is stored in a local storage device. Scaling factors for each descriptive attribute are determined taking into account a distribution of the original values for the corresponding descriptive attribute and a common base for the descriptive attributes. Weighting factors are determined for each descriptive attribute. The composite tie metric is computed for an edge based on the original value, scaling factor, and weighting factor for the descriptive attributes.

Abstract: A system and method for generating a subscriber churn prediction includes receiving call detail records from a network operator detailing communication between subscribers of the network operator and determining tie-strengths between subscribers based on the call detail records. The system and method further includes generating a net churn influence accumulated at each subscriber from the tie-strengths by propagating churner influence between subscribers due to churn events.

Abstract: A method for providing advice to a service provider includes; a) accessing customer, network, and service data stored in disparate data sources, the data relating to services provided to customers by a service provider over a network infrastructure, a virtualization platform presenting the disparate data in a common logical view; b) processing the data in an analytics platform using a service advisor algorithm to form conclusions and predictions regarding management of customer churn and generate advice; and c) formulating results from the processing to enable the service provider to consider the data, conclusions, predictions, and advice in relation to reduction of customer churn. The service advisor algorithm may also be used for personalization of service provided to customers, targeted marketing of services to customers or non-customers, and management of the network infrastructure. An apparatus for providing advice to a service provider includes the virtualization and analytics platforms.

Abstract: A method for organizing identifying information for web-based resources may include: a) initializing an organizing tool and a web browser from a user device in operative communication with a network; b) searching the network for web-based resources associated with a search query by accessing the web search engine via the web browser; c) receiving a results list from the web search engine at the user device in response to the search query; and d) creating an organized file with the organizing tool based on the results list, the organized file including a root node with identifying information for the search query and a first level selectively populated with identifying information for one or more web-based resources included in the results list. A system for organizing identifying information for web-based resources may include a network, an organizing tool; and a user device.

Abstract: In an exemplary method, a call origination request containing a toll-free telephone number of the called party is received from a wireless handset supported by a mobility service provider at a switching node of the telecommunication network. A determination is made if the called party has agreed to pay for at least a portion of the telecommunication service charge by the mobility service provider for providing wireless access to the wireless handset for the call. If the called party has agreed to pay for at least a portion of the telecommunication service charge by the mobility service provider, a call detail record associated with said call is generated that contains information indicating that the called party will be responsible for at least the portion of the telecommunication service charge by the mobility service provider. The call is then terminated to the called party.
