Solution Overview
Problem
Current natural language understanding (NLU) systems face limitations in scalability, memory usage, and update efficiency due to the tight coupling of feature extraction and query understanding processes, which hinder their ability to handle increased data and domains effectively.
Innovation Solution
A distributed NLU system architecture that separates feature extractors onto different servers, allowing for parallel processing and independent updates, enabling more accurate, reliable, and efficient natural language understanding by aggregating features from multiple servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If feature extractors and query understanding processes are tightly coupled on the same server, then system simplicity is maintained, but scalability and memory usage are limited
Solution Approach 1:
The system is divided into separate components: feature extractors are deployed as independent services on different servers, while the query understanding process runs on a separate server. This segmentation allows each component to be scaled independently, improving overall system scalability without requiring the entire system to be redesigned.
Solution Approach 2:
The feature extraction functionality is extracted from the query understanding server and placed as separate, distributed services. This extraction removes the memory and processing constraints that limited the original tightly-coupled architecture, enabling the system to handle larger datasets and more domains.
2Reliability
If feature extractors are located on the same server as the language understanding model, then data transmission is minimized, but update efficiency and system reliability are reduced
Solution Approach 1:
By segmenting the system into separate feature extractor services and a language understanding server, updates to feature extractors can be performed independently without affecting the language understanding model. This allows the system to maintain high reliability during updates and enables continuous operation.
Solution Approach 2:
The distributed architecture enables dynamic updates to feature extractors while the system remains operational. The language understanding server can continue processing queries while feature extractors are updated in the background, improving both reliability and update efficiency.
3Productivity
If all feature extractors are hosted on a single server, then system complexity is minimized, but processing speed and productivity are limited by memory constraints
Solution Approach 1:
Feature extractors are segmented across multiple servers, allowing parallel processing of features from different domains. This distribution enables simultaneous feature extraction and reduces memory constraints on any single server, thereby improving processing speed and productivity.
Solution Approach 2:
The system transitions from a single-server architecture to a multi-server distributed architecture, adding the dimension of spatial distribution. This allows feature extraction to occur in parallel across multiple servers, significantly improving processing throughput without proportionally increasing complexity.
