Abstract: One or more implementations allow for systems, methods, and devices for teaching and/or assessment of one or more spoken language skills through analysis of one or more pronunciation characteristics of one or more individual language components of a teaching string audio sample data that corresponds to the user's speaking of the teaching string.

Abstract: Subscription-based notification using event channels that each correspond to a particular scope. Each channel manages notifications through the use of a schema definition. The event subscriptions identify the position and attributes that any desired event notification would take in the schema definition. The channel then receives event notifications in the form of XML fragments. The channel then determines the position that the XML fragment would take as defined by the schema definition. The channel determines whether the position and attributes of the event notification matches the position and attributes of the event subscription. If a match is found, then the event notification is copied and forwarded to the recipient designated in the corresponding subscription.

Abstract: A health model builder may construct a health model from instrumentation of software. To do so, the instrumentation of the software component may be mapped to states of operation of the software component and the instrumentation may be grouped together. A health model may be built with the states of operation resulting from mapping the instrumentation to states of operation of the software component and with transitions between the states of the health model that represent an occurrence of instrumentation in an instrumentation group. The system allows for identification of anti-alert instrumentation to be added where instrumentation is missing for reporting recovery from failure. Moreover, a blame component may be identified for any instrumentation of a software component that indicates it failed because of another software component.

Abstract: An improved system and method for building a health model is provided. A health model builder may construct a health model from instrumentation of software. To do so, the instrumentation of the software component may be mapped to states of operation of the software component and the instrumentation may be grouped together. A health model may be built with the states of operation resulting from mapping the instrumentation to states of operation of the software component and with transitions between the states of the health model that represent an occurrence of instrumentation in an instrumentation group. The system allows for identification of anti-alert instrumentation to be added where instrumentation is missing for reporting recovery from failure. Moreover, a blame component may be identified for any instrumentation of a software component that indicates it failed because of another software component.
