Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard LLM is used for general conversations, then the model can handle diverse topics, but it lacks expertise in specific industries and fields leading to inconsistent and fragmented conversations
Solution Approach 1:
The system segments knowledge into structured domains (psychology, medicine, law, etc.) with hierarchical taxonomies. Each domain contains specialized concepts, relationships, and expertise that can be independently managed and retrieved, allowing the LLM to access relevant domain knowledge without being constrained by general-purpose training limitations.
Solution Approach 2:
A knowledge graph serves as an intermediary between the LLM and domain expertise. The knowledge graph stores structured relationships and factual knowledge, enabling the LLM to retrieve accurate, consistent information from external sources rather than relying solely on its internal parameters, thus improving both domain expertise and conversation consistency.
2Reliability
If contextual information is stored to maintain conversation coherence, then narrative consistency improves, but system complexity increases due to memory management requirements
Solution Approach 1:
Memory is segmented into distinct components: short-term memory for immediate conversation context, long-term memory for persistent user profiles and preferences, and episodic memory for specific conversation events. This segmentation allows each memory type to be managed independently with appropriate retrieval strategies, reducing overall system complexity while maintaining narrative consistency.
Solution Approach 2:
The memory system dynamically adapts its structure and retrieval behavior based on conversation context. Memory slots are created, updated, and retired automatically based on conversation flow, allowing the system to maintain relevant context without requiring manual memory management or complex fixed-structure memory architectures.
3Reliability
If multiple information retrieval methodologies are deployed to maintain context, then conversation quality improves, but processing time and computational resources increase
Solution Approach 1:
The system retrieves only the necessary portion of contextual information required for the current turn rather than accessing complete conversation history or all domain knowledge. Context windows are dynamically adjusted to include only relevant segments, and knowledge graph queries are optimized to retrieve minimal sufficient information, maintaining context accuracy while reducing processing overhead.
Solution Approach 2:
Context retrieval is performed continuously and incrementally throughout the conversation rather than in large batches. The system maintains running context summaries and updates memory structures in real-time, allowing each turn to build upon previously established context without requiring repeated full-context analysis, thus improving response speed while maintaining accuracy.
Data Source
AI summary
In one implementation, a computer-implemented method involves receiving a user message corresponding to a query or a statement to AI chatbot, performing preprocessing operations resulting in generation of initial context of the user message by extracting text of the user message, metadata of the user message, and a conversation identifier, obtaining historical context pertaining to the user message from a plurality of storage mechanisms provided in differing formats including a knowledge graph, a vector database comprised of vector embeddings, and a database comprising text summaries of prior conversations between the user and the AI chatbot, generating a prompt for a LLM that instructs the LLM to generate a response to the user message that is based on and consistent with the user message, the initial content, and the historical context, and providing a final response to the user that is corresponds to an LLM-generated response.
