Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G10L 15/00

US Classification:

704243, 704246, 704251, 704255, 7042565, 704257

Abstract:

A natural language business system and method is developed to understand the underlying meaning of a person's speech, such as during a transaction with the business system. The system includes a speech recognition engine, and action classification engine, and a control module. The control module causes the system to execute an inventive method wherein the speech recognition and action classification models may be recursively optimized on an unisolated performance metric that is pertinent to the overall performance of the natural language business system, as opposed to the isolated model-specific criteria previously employed.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 15/16

US Classification:

709217000

Abstract:

Techniques are provided for addressing a problem pertaining to a computer of a user. In an exemplary method, the obtaining of a problem statement associated with the problem pertaining to the computer of the user is facilitated.

Appl. No.:

7/657160

Inventors:

Cheng M. Wu - Cerritos CA

International Classification:

A61F 544

US Classification:

53429

Abstract:

This invention relates to a method for packaging birth control and disease preventing device that has sheath and shield, and more particularly to a method having steps including: pleats the protecting shield toward tubular sheath forming a pleated star-like shape near the closed end of the sheath, bends the pleated star-like shape portion of the shield close to the tubular sheath forming a whirled-like cylindrical tubular, rolls the secure-and-rolled-up ring in the longitudinal direction toward the closed end of the sheath, and packs the rolled-up device into a water proof sealed container.

Inventors:

Cheng M. Wu - Cerritos CA

International Classification:

A61F 600

US Classification:

128844

Abstract:

This invention relates to a birth control and disease preventing device, and more particularly to a device having a large pubic elastic shield (40) integrated about a secure-and-rolled-up (toroidal) ring (28) which is integrated about the open end (26) of a tubular portion that is configured as a conventional condom. The pubic shield has a stationary upper portion (42) and two movable lower portions (44), (46), and has a folding portion (48) between the movable portion to improve the protection of the area around the pubic and the scrotum when the user's legs are in different positions.

Abstract:

A method, apparatus and computer program product for creating a dialog system for web content is described. Knowledge is extracted from a target web application for the dialog system. The knowledge includes an organizational structure of the target web application and domain knowledge pertinent to the target web application. A deep learning process associates the domain knowledge with the organization structure of the target application. A plurality of knowledge sources of different respective types are created from the domain knowledge and the organizational structure. Each of the knowledge sources is used for providing answers to user queries to the dialog system. As part of the invention, a semantic matcher is provided to select among the answers provided by the plurality of knowledge sources for a best answer to a user query.

Abstract:

A method, apparatus and computer program product for presenting a user interface for a conversational system is described. A user input is received in a dialog between a user and the conversational system, the user input in a natural language. A domain trained semantic matcher is used to determine a set of entities and a user intent from the user input. One or more queries is generated to selected ones of a plurality of knowledge sources, the knowledge sources created from domain specific knowledge. The results from the one or more queries are ranked based on domain specific knowledge. A system response is presented in the dialog based on at least a highest ranked result from the plurality of knowledge sources.
