Method for generating natural language in computer-based dialog systems

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 normalised interface structures from the structured deep syntactic input tree;
• Step 6:
• realizing and expanding structure types by inserting and/or transforming of pre-defined 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.
