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.

The method includes obtaining the measured pressure via several measuring points, and obtaining actually measured value of each measuring point; calculate the theoretical pressure at each measuring points by using the real-time operational data as inputs, evaluating a hole cleaning condition by applying a difference between a theoretical pressure drop and a measured pressure drop to a developed pressure driven hole cleaning model, which gives the risk of insufficient hole cleaning problems and problematic locations. The theoretical pressure drop between two adjacent measurement points along wellbore includes the pressure drop caused by friction effect and hydrostatic effect.
