  • Publication number: 20060123045
    Abstract: Methods and apparatus, including computer products, for generating a natural language expression in response to a query. A computer-implemented method of generating a natural language expression in response to a query, includes generating a text frame from the query, and processing the text frame in conjunction with a grammar and one or more logic configuration files applied recursively to the text frame to generate the natural language expression from the query, the logic configuration files including functions that can pass arguments.

  • Patent number: 5640487
    Abstract: The present invention is an n-gram language modeler which significantly reduces the memory storage requirement and convergence time for language modelling systems and methods. The present invention aligns each n-gram with one of "n" number of non-intersecting classes. A count is determined for each n-gram representing the number of times each n-gram occurred in the training data. The n-grams are separated into classes and complement counts are determined. Using these counts and complement counts factors are determined, one factor for each class, using an iterative scaling algorithm. The language model probability, i.e., the probability that a word occurs given the occurrence of the previous two words, is determined using these factors.
