Agglutination Preprocessor for Inflected Grammar Parsing

The patent introduces an agglutination preprocessor as an intermediary component between the tokenizer and parser. This preprocessor handles the complex task of generating inflected forms through string concatenation and rewrite rules, allowing the main grammar to remain simple while still supporting inflections. The preprocessor acts as a mediator that translates base forms into inflected forms without requiring the grammar itself to become complex.

The patent segments the natural language processing pipeline into distinct components: tokenizer, agglutination preprocessor, and parser. By separating the generation of inflected forms (handled by the preprocessor) from the parsing of grammatical structures (handled by the parser), the system avoids the complexity of integrating inflection handling directly into the grammar rules. Each component has a specific, simplified function.

The agglutination preprocessor performs preliminary actions by generating all possible inflected forms from base forms before the parsing stage. Through rewrite rules and string concatenation, it pre-computes inflections such as plurals, possessives, and conjugations. This preliminary generation eliminates the need for time-consuming manual grammar extension during development and maintenance.

Instead of manually duplicating and modifying grammar rules for each inflected form, the system uses template-based rewrite rules that automatically generate the necessary grammar extensions. The preprocessor copies and transforms base forms according to systematic rules, reducing manual effort and minimizing errors associated with repetitive grammar modification.
