Systems and methods for generating markup-language based expressions from multi-modal and unimodal inputs
First Claim
1. A method for generating markup-language-based expressions from an input into an unimodal or a multimodal device, comprising:
- receiving at least one data input in at least one input mode of a recognition device;
generating at least one input lattice representing the at least one data input;
using at least one finite-state device to perform a function using the at least one generated input lattice, the finite-state device having symbols based on markup-language semantics, wherein performing the function comprises mapping a first markup-language expression to a second markup-language expression using a transducer relating the first-markup-language expression to the second-markup-language expression;
generating a result finite-state device representing a result of the performed function, the result finite-state device relating at least one set of input symbols to at least one set of output symbols;
concatenating output symbols in the at least one set of output symbols of the result finite-state device to generate at least one markup-language expression;
generating the at least one markup-language expression; and
outputting the at least one generated markup-language expression to a processor.

Abstract
When using finite-state devices to perform various functions, it is beneficial to use finite state devices representing regular grammars with terminals having markup-language-based semantics. By using markup-language-based symbols in the finite state devices, it is possible to generate valid markup-language expressions by concatenating the symbols representing the result of the performed function. The markup-language expression can be used by other applications and/or devices. Finite-state devices are used to convert strings of words and gestures into valid markup-language, for example, XML, expressions that can be used, for example, to provide an application program interface to underlying system applications.
