Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developing chatbots is challenging due to the difficulty in finding sufficient linguistic expressions for training, especially in multi-lingual environments, leading to suboptimal chatbot quality and often skipping validation processes.
Innovation Solution
An automated method for generating pre-categorized linguistic expressions using templates, which allows for extensive expression generation, augmentation, filtering, and validation, enabling iterative refinement of chatbot training and validation processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional manual methods are used to collect linguistic expressions for chatbot training, then the chatbot can be developed with some training data, but the quality of training data is insufficient and the development process becomes extremely time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-generating linguistic expressions using templates before actual chatbot training begins. The system creates a comprehensive dataset of training expressions, validation expressions, and edge-case expressions in advance, which significantly reduces the time required for data collection while maintaining high quality. This is evident in the automated generation of thousands of training expressions across multiple languages before model training starts.
Solution Approach 2:
The patent uses copying by creating linguistic expressions through template-based generation rather than manual collection. Templates serve as reusable patterns that can be instantiated multiple times to generate diverse training expressions. This allows the system to copy and adapt expression structures across different languages and contexts, efficiently producing high-quality training data without manually collecting each expression individually.
2Productivity
If the chatbot is trained with limited linguistic expressions, then the development process is faster, but the chatbot performance and accuracy deteriorate
Solution Approach 1:
The patent applies segmentation by dividing the linguistic expression dataset into distinct segments: training expressions, validation expressions, and edge-case expressions. This segmentation allows the system to efficiently manage large volumes of data while ensuring each segment serves its specific purpose. The training set is used for model learning, the validation set for performance evaluation, and edge-case expressions for handling unusual inputs, thereby maintaining high chatbot performance without compromising development speed.
Solution Approach 2:
The patent uses parameter changes by systematically varying parameters such as language, expression structure, and contextual elements within templates to generate diverse linguistic expressions. This allows the system to efficiently expand the training dataset across multiple languages and expression types, improving chatbot performance and reliability without proportionally increasing development time.
3Manufacturing precision
If validation processes are performed thoroughly, then chatbot quality is improved, but the development time and complexity increase significantly
Solution Approach 1:
The patent applies preliminary action in validation by pre-generating a dedicated validation expression set before model training. This validation set includes diverse expressions and edge cases that are prepared in advance, allowing for systematic and thorough validation without adding complexity during the training phase. The pre-prepared validation expressions enable comprehensive quality assessment while maintaining a clear, manageable validation process.
4Adaptability or versatility
If multiple languages are supported in the chatbot, then the versatility and user base are expanded, but the difficulty of finding training data is multiplied
Solution Approach 1:
The patent applies universality by using language-agnostic templates that can generate linguistic expressions across multiple languages. The template structure remains universal while the actual expressions are adapted to different languages through translation and localization. This allows the system to efficiently support multiple languages without separately collecting training data for each language, thereby expanding versatility while maintaining ease of data generation.
Solution Approach 2:
The patent uses parameter changes by systematically varying the language parameter within the template generation process. This allows the same template structure to produce valid linguistic expressions in multiple languages by changing only the language-specific parameters, making multi-language support efficient and scalable without multiplying the data collection effort.
Data Source
AI summary
Linguistic expressions for training a chatbot can be generated in an automated system via linguistic expression templates that are associated with intents. The pre-categorized linguistic expressions can then be used for training and validation. Chatbot development can thus be improved by having a large number of expressions for development, leading to a more robust chatbot. In practice, the process can iterate with modifications to the templates until a suitable benchmark is met. The technique can be applied across human languages to generate chatbots conversant in any number of languages and is applicable to a variety of domains.
