摘要:
A method to select features for maximum entropy modeling in which the gains for all candidate features are determined during an initialization stage and gains for only top-ranked features are determined during each feature selection stage. The candidate features are ranked in an ordered list based on the determined gains, a top-ranked feature in the ordered list with a highest gain is selected, and the model is adjusted using the selected top-ranked feature.

A system for generating language modeling data for a speech recognition system includes an expression extractor to extract expression from domain-specific data of an existing domain using a base of linguistic knowledge, a concept structure mapper to map extracted expression to expression in a new domain using vocabulary for the new domain, a concatenation module to concatenate extracted expression with domain-general data, and a filter arrangement to identify and filter out unrealistic expression in the mapped or concatenated expression.

A method and system to parameterize a spoken language dialog system, includes providing a storage area to store at least one parameter value, integrating a subcomponent with at least one module of the spoken language dialog system, and configuring the subcomponent to access the at least one parameter value and to adjust an operation or output of the module based on the at least one parameter value.
摘要:
A system and method to interactively converse with a cognitively overloaded user of a device, includes maintaining a knowledge base of information regarding the device and a domain, organizing the information in at least one of a relational manner and an ontological manner, receiving speech from the user, converting the speech into a word sequence, recognizing a partial proper name in the word sequence, identifying meaning structures from the word sequence using a model of the domain information, adjusting a boundary of the partial proper names to enhance an accuracy of the meaning structures, interpreting the meaning structures in a context of the conversation with the cognitively overloaded user using the knowledge base, selecting a content for a response to the cognitively overloaded user, generating the response based on the selected content, the context of the conversation, and grammatical rules, and synthesizing speech wave forms for the response.
摘要:
A computerized method for building and running natural language understanding systems, wherein a natural language understanding system takes a sentence as input and returns some representation of the possible meanings of the sentence as output (the “interpretation”) using a run-time interpreter that assigns interpretations to sentences and a compiler that produces (in a computer memory) an internal specification needed for the run-time interpreter from a user specification of the semantics of the application. The compiler builds a natural language system, while the run-time interpreter runs the system.

A dialog system includes a processor. The system can further include a dialog manager. The dialog manager can be configured to receive input from a user using the processor. The system can further include a user category classification and detection module, which is configured to identify categories for the user from the received input. The system can further include a user mood detection and tracking module configured to identify a mood of the user. The system can further include a user physical and mind state and energy level detection module configured to identify a mental status of the user. The system can further include a user acquaintance module configured to identify an acquaintance status of the user. The system can further include user personality detection and tracking module configured to identify a personality status of the user. The system can further include a conversational context detection and response generation module.

A method of providing information assistance services includes generating a plurality of service requests for a plurality of request elements that are generated from a single client request received by a processor. The service requests are sent to both software application service providers that are executed by the processor and remote service providers that are connected to the local processor through a data network. The processor receives a plurality of service responses from the service providers, generating at least one output message element corresponding to the service responses, and sending the output message data to at least one output device that is operatively connected to the processor to produce a response to the client request.

A method for verifying that a person is registered to use a telemedical device includes identifying an unprompted trigger phrase in words spoken by a person and received by the telemedical device. The telemedical device prompts the person to state a name of a registered user and optionally prompts the person to state health tips for the person. The telemedical device verifies that the person is the registered user using utterance data generated from the unprompted trigger phrase, name of the registered user, and health tips.
摘要:
A method of interpreting input from a user includes providing a surface within reach of a hand of the user. A plurality of locations on the surface that are touched by the user are sensed. An alphanumeric character having a shape most similar to the plurality of touched locations on the surface is determined. The determining includes collecting information associated with hand region localized modules, and modeling the information using statistical models. The user is informed of the alphanumeric character and/or a word in which the alphanumeric character is included. Feedback is received from the user regarding whether the alphanumeric character and/or word is an alphanumeric character and/or word that the user intended to be determined in the determining step.

An in-vehicle information system includes a camera and a controller that accept gesture input. A controller receives frames of video data and generates trajectory data for a movement of a hand in the video data. The controller uses a first hidden Markov model (HMM) to decode a sequence of strokes from the trajectory data, removes a starting and ending stroke to form an edited stroke sequence, and re-normalizes the strokes in the edited stroke sequence. The controller uses a second HMM corresponding to a predetermined set of characters to identify a character corresponding to the re-normalized edited stroke sequence.
