Method for generating natural language in computer-based dialog systems
First Claim
1. A method for generating natural language in computer-based dialog systems, characterized by a highly controllable procedural approach, comprising the following steps:
- Step 1;
generating an input tree with semantic-pragmatic deep structure from an input file received from a strategic component of the dialog system, wherein the input file comprises a sequence of simple semantic representation language (SSRL) statements;
Step 2;
inserting elementary syntactic information into the tree structure and onto the tree nodes;
Step 3;
applying elementary operations such as sub-tree insertion and manipulation, for instance, identification of coordinations, attributes and relations;
Step 4;
accessing lexical and/or language specific information to the tree;
Step 5;
generating syntactic structures oriented towards normalized interface structures from the structured deep syntactic input tree;
Step 6;
realizing and expanding structure types by inserting and/or transforming of predefined structures, inserting determiners, and/or ordering of sub-structures;
Step 7;
generating morphologic transformations;
Step 8;
optionally, carrying out final refinements, comprising phonetic refinement, pretty print and/or cleaning operations of the tree and the node decorations;
Step 9;
outputting a graphic representation of the final tree structure and/or a text string thereof.

Abstract
The invention relates to a method for generating natural language in computer based dialog system. The invention generating an input tree from an input file of a simple semantic representation language (SSRL) statements; inserting elementary syntactic information into the tree; applying elementary operations such as sub-tree insertion and manipulation; accessing lexical and language specific information; generating syntactic structures oriented towards normalized interface structures from the structured deep syntactic input tree; realizing and expanding structure types by inserting and/or transforming of pre-defined structures, inserting determiners and ordering sub-structures; generating morphologic transformations; carrying out final refinements, comprising phonetic refinement, pretty print and/or cleaning operations of the tree and the node decorations and outputting a graphic and/or textual representation of the final tree structure.
