Abstract: A technique enables coordination of unrelated software components to facilitate extensive recovery point management on a snapshot or recovery point through the use of a flexible tag structure. The tag is organized and arranged as a {key=value,[value] . . . } structure wherein the key denotes an operation that requires coordination between the unrelated software components and the value(s) denote multi-cardinality that provide parameters for coordination of the operation. The multi-cardinality aspect of the flexible tag structure provides a set of values associated with the key of the tag that enables a software component and/or protocol to insert its value(s) into the tag structure for its interpretation. The technique thus provides an extensible model where multiple components/protocols use the tag to coordinate operations on the RP by conveying certain meaning/interpretations of the tag and its values.

Abstract: Techniques for determining and storing relevant context information for a user input, such as a spoken input, are described. In some embodiments, context information is determined to be relevant on an audio frame basis. Context scores for different types of context data (e.g., prior dialog turn data, user profile data, device information, etc.) are determined for individual audio frames corresponding to a spoken input. Based on the corresponding context scores, the most relevant context is stored in a local context cache. The local context cache is updated as subsequent audio frames, of the user input, are processed. The data stored in the context cache is provided to downstream components to perform tasks such as ASR, NLU and SLU.
