摘要:
Provided are methods, apparatus and computer programs for remote monitoring of data. Log data output by an application program running on a storage-constrained apparatus is saved to local system memory—either as an in-memory data file or as output from one application piped to the input of another, or as a named pipe that passes data to a local publisher program—and then captured by the local publisher program. The local publisher program sends the data to a publish/subscribe broker, which can retain the most recent publications for analysis by one or more subscribers. This avoids the need to save large amounts of data to disk storage on the storage-constrained apparatus, and ensures that console output data and log data that is often discarded by headless, storage-constrained systems is available for analysis. The combination of the retain feature and publishing of output data in response to failure of a monitoring application ensures the availability of the data that was output just before the failure, which is generally the most useful data for problem diagnosis.

The present invention provides methods, apparatus and computer programs for event-based control of subscription matching in a publish/subscribe communications environment. Activation and/or deactivation events are associated with subscriptions at a publish/subscribe broker and are used to control when a subscription is active. The broker is responsive to temporally-unpredictable events, such as receipt of a published message on a predefined activation topic, to activate subscription matching for messages that are subsequently received or which have been received earlier and retained at the broker. Conventional subscription matching can be avoided for a registered subscription while that subscription is inactive, and subscribers are not required to explicitly and repeatedly subscribe and unsubscribe.

The methods and systems described herein may asynchronously process natural language utterances to provide real-time response performance and natural interaction with users. In particular, the methods and systems described herein may use various natural language speech recognition and interpretation components to identify a request (e.g., a query or command) in an utterance. The request identified in the utterance may then be processed with one or more domain agents, which may submit duplicate queries to multiple different data sources to process the request. The domain agents may then asynchronously evaluate responses to the duplicate queries to return results to users in a timely and natural manner, and further to account the fact that the different data sources may respond to the queries at different speeds, provide unsatisfactory responses to the queries, or fail to respond to the queries at all.

The systems and methods described herein may filter and eliminate noise from natural language utterances to improve accuracy associated with speech recognition and parsing capabilities. In particular, the systems and methods described herein may use a microphone array to provide directional signal capture, noise elimination, and cross-talk reduction associated with an input speech signal. Furthermore, a filter arranged between the microphone array and a speech coder may use band shaping, notch filtering, and adaptive echo cancellation to optimize a signal-to-noise ratio associated with the speech signal. The speech signal may then be sent to the speech coder, which may use adaptive lossy audio compression to optimize bandwidth requirements associated with transmitting the speech signal to a main unit that provides the speech recognition, parsing, and other natural language processing capabilities.
摘要:
The systems and methods described herein may recognize natural language utterances that include queries and/or commands and execute the queries and/or commands based on user-specific profiles. The systems and methods described herein may include a complete speech-based information query, retrieval, presentation and command environment that makes significant use of context, prior information, domain knowledge, and the user-specific profiles to achieve a natural environment for one or more users making queries or commands in multiple domains. Through this integrated approach, a complete speech-based natural language query and response environment can be created and tailored to specific users. For example, the systems and methods described herein may create, store, and use extensive personal profile information for different users, thereby improving the reliability of determining the context and presenting the results that the specific users may expect for a particular question or command.

Systems and methods for receiving natural language queries and/or commands and execute the queries and/or commands. The systems and methods overcome the deficiencies of prior art speech query and response systems through the application of a complete speech-based information query, retrieval, presentation and command environment. This environment makes significant use of context, prior information, domain knowledge, and user specific profile data to achieve a natural environment for one or more users making queries or commands in multiple domains. Through this integrated approach, a complete speech-based natural language query and response environment can be created. The systems and methods creates, stores and uses extensive personal profile information for each user, thereby improving the reliability of determining the context and presenting the expected results for a particular question or command.

Method and apparatus for running a test program for an element of a computer system by detecting idle processor cycles in a processor in the system, selecting a test program for an element of the computer system; and running the test program for the element on the processor in response to detection of idle processor cycles.
摘要:
Mobile systems and methods that overcomes the deficiencies of prior art speech-based interfaces for telematics applications through the use of a complete speech-based information query, retrieval, presentation and local or remote command environment. This environment makes significant use of context, prior information, domain knowledge, and user specific profile data to achieve a natural environment for one or more users making queries or commands in multiple domains. Through this integrated approach, a complete speech-based natural language query and response environment can be created. The invention creates, stores and uses extensive personal profile information for each user, thereby improving the reliability of determining the context and presenting the expected results for a particular question or command. The invention may organize domain specific behavior and information into agents, that are distributable or updateable over a wide area network. The invention can be used in dynamic environments such as those of mobile vehicles to control and communicate with both vehicle systems and remote systems and devices.

To handle web server failures, a client comprises a health monitor for monitoring the status of the web server, the client being an originator of requests for web pages from the web server. The health monitor receives status information for the web server. If the health monitor determines that the web server has failed, the health monitor redirects requests for web pages hosted by the failed web server to another web server that is working.
