Patent number: 8620669Abstract: Disclosed is a task classification system that interacts with a user. The task classification system may include a recognizer that may recognize symbols in the user's input communication, and a natural language understanding unit that may determine whether the user's input communication can be understood. If the user's input communication can be understood, the natural language understanding unit may generate understanding data. The system may also include a communicative goal generator that may generate communicative goals based on the symbols recognized by the recognizer and understanding data from the natural language understanding unit. The generated communicative goals may be related to information needed to be obtained from the user. The system may further include a sentence planning unit that may automatically plan one or more sentences based on the communicative goals generated by the communicative goal generator with at least one of the sentences plans being output to the user.Type: GrantFiled: May 14, 2012Date of Patent: December 31, 2013Assignee: AT&T Intellectual Property II, L.P.Inventors: Marilyn A. Walker, Owen Christopher Rambow, Monica Rogati

Patent number: 8209186Abstract: The invention relates to a method for sentence planning (120) in a task classification system that interacts with a user. The method may include recognizing symbols in the user's input communication and determining whether the user's input communication can be understood. If the user's communication can be understood, understanding data may be generated (220). The method may further include generating communicative goals (3010) based on the recognized symbols and understanding data. The generated communicative goals (3010) may be related to information needed to be obtained form the user. The method may also include automatically planning one or more sentences (3020) based on the generated communicative goals and outputting at least one of the sentence plans to the user (3080).Type: GrantFiled: May 18, 2011Date of Patent: June 26, 2012Assignee: AT&T Intellectual Property II, L.P.Inventors: Marilyn A.

Patent number: 8185401Abstract: The invention relates to a system that interacts with a user in an automated dialog system (100). The system may include a communicative goal generator (210) that generates communicative goals based on a first communication received from the user. The generated communicative goals (210) may be related to information needed to be obtained from the user. The system may further include a sentence planning unit (220) that automatically plans one or more sentences based on the communicative goals generated by the communicative goal generator (210). At least one of the planned sentences may be then output to the user (230).Type: GrantFiled: May 28, 2010Date of Patent: May 22, 2012Assignee: AT&T Intellectual Property II, L.P.Inventors: Marilyn A.

Patent number: 7562005Abstract: A system, method and computer-readable medium for generating natural language utilizes a stochastic process to choose a derivation tree according to a predetermined grammar, such as tree-adjoined grammar (TAG). A word lattice is created from a single semi-specified derivation tree and the proper path (i.e., desired output string) is selected from the lattice using a least cost, or other appropriate algorithms.Type: GrantFiled: March 22, 2007Date of Patent: July 14, 2009Assignee: AT&T Intellectual Property II, L.P.Inventors: Srinivas Bangalore, Owen Christopher Rambow

The method may include generating communicative goals (210) based on a first communication received from the user. The generated communicative goals (210) may be related to information needed to be obtained from the user. Based on the generated communicative goals (210) one or more sentences may be automatically planned (220) to achieve at least a portion of the communicative goals (210). Then, at least one of the planned sentences (220) may be output to the user.Type: ApplicationFiled: October 29, 2002Publication date: June 19, 2003Inventors: Marilyn A.
