Solution Overview
Problem
Current natural language processing methods face challenges in efficiently and accurately processing vast amounts of human communications across multiple languages, as they often rely on rule-based systems that fail to capture ambiguities and require manual handling, which is cost-inefficient and overwhelming.
Innovation Solution
A tokenizer and tagger system that uses a combination of statistical models and rules to divide text into tokens, with the ability to generate new rules from statistical models based on high likelihoods, allowing for language-agnostic processing and incorporating human annotations to improve accuracy, and can handle multiple languages by outputting tokens in a common format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If rule-based systems are used for natural language processing, then processing structure is simple and easy to implement, but accuracy is insufficient due to inability to capture ambiguities and language variations
Solution Approach 1:
The system segments the natural language processing task into multiple independent modules: tokenization module, statistical analysis module, rule generation module, and processing module. Each module handles a specific aspect of the problem, allowing the system to achieve high accuracy through specialized components while maintaining manageable overall complexity through modular architecture.
Solution Approach 2:
The system dynamically adapts its processing approach by generating rules on-the-fly based on statistical analysis of input data. Rather than relying on static pre-defined rules, the system adjusts its behavior in real-time based on the characteristics of the language being processed, enabling it to handle ambiguities and variations while maintaining system simplicity through adaptive rather than complex predetermined structures.
2Productivity
If manual handling is used for language-specific processing, then processing accuracy can be maintained through human expertise, but processing efficiency decreases and costs increase
Solution Approach 1:
The system performs self-service by automatically generating its own processing rules through statistical analysis of the input data. The rule generation module analyzes patterns in the training data and creates optimized processing rules without human intervention, enabling the system to achieve both high efficiency through automation and high accuracy through data-driven rule optimization.
Solution Approach 2:
The system implements feedback mechanisms where the processing results are continuously analyzed and used to refine the generated rules. The statistical analysis module monitors processing outcomes and adjusts rule generation accordingly, creating a self-improving system that maintains high accuracy while operating efficiently without manual intervention.
3Adaptability or versatility
If language-specific processing is implemented for each language, then processing accuracy for that language is improved, but system complexity and adaptability to new languages increase
Solution Approach 1:
The system implements a universal processing framework that can handle multiple languages through a single integrated architecture. The statistical analysis module and rule generation module are language-agnostic and automatically adapt to any language by analyzing its specific patterns in the training data, eliminating the need for separate language-specific implementations while maintaining high accuracy for each language.
Solution Approach 2:
The system changes its processing parameters dynamically based on the detected language characteristics. Rather than using fixed language-specific configurations, the system adjusts statistical models and rule generation parameters on-the-fly based on the input data's linguistic features, enabling seamless adaptation to new languages without increasing system complexity.

AI summary
Systems, methods, and apparatuses are presented for a novel natural language tokenizer and tagger. In some embodiments, a method for tokenizing text for natural language processing comprises: generating from a pool of documents, a set of statistical models comprising one or more entries each indicating a likelihood of appearance of a character/letter sequence in the pool of documents; receiving a set of rules comprising rules that identify character/letter sequences as valid tokens; transforming one or more entries in the statistical models into new rules that are added to the set of rules when the entries indicate a high likelihood; receiving a document to be processed; dividing the document to be processed into tokens based on the set of statistical models and the set of rules, wherein the statistical models are applied where the rules fail to unambiguously tokenize the document; and outputting the divided tokens for natural language processing.
