Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional correlation analysis of structured data is performed, then all possible correlations can be identified, but the computing resources and time required become prohibitive
Solution Approach 1:
The system performs preliminary actions by constructing a knowledge graph that encodes existing biomedical knowledge, relationships, and contextual information before conducting correlation analysis. This pre-structured knowledge base enables the system to guide and constrain subsequent correlation calculations, focusing computational resources on promising hypotheses rather than exhaustively analyzing all possible feature combinations.
Solution Approach 2:
The knowledge graph serves as an intermediary structure that mediates between raw patient data and correlation analysis. It transforms unstructured or semi-structured biomedical data into a structured representation with explicit relationships, enabling more efficient and targeted hypothesis generation without requiring exhaustive correlation calculations across all features.
2Measurement precision
If exhaustive correlation analysis is performed, then all potential biomarkers can be discovered, but the number of correlations identified exceeds the capacity of experts to review them
Solution Approach 1:
The system incorporates feedback mechanisms where the knowledge graph is continuously updated and refined based on correlation analysis results. The system learns from identified correlations, adjusts its hypothesis generation strategy, and prioritizes novel versus known relationships. This feedback loop enables automated filtering and ranking of hypotheses, reducing the burden on experts to review all correlations manually.
Solution Approach 2:
The system replaces the mechanical process of manual expert review with automated computational methods. Machine learning algorithms and knowledge graph reasoning automatically evaluate, prioritize, and filter correlations, substituting human expert labor with computational intelligence that can handle large volumes of data without fatigue or inconsistency.
3Reliability
If manual biomedical discovery processes are used, then expert judgment can be applied, but the processes are slow, expensive, and ad hoc
Solution Approach 1:
The system combines multiple functions into a unified platform that integrates knowledge graph construction, correlation analysis, hypothesis generation, and prioritization. This multi-functional system automates previously manual processes while maintaining expert-level judgment through embedded knowledge and algorithms, thereby increasing productivity without sacrificing the quality of expert assessment.
Solution Approach 2:
The system enables continuous automated discovery processes rather than ad hoc manual analysis. The knowledge graph and correlation analysis framework can operate continuously on new data as it becomes available, systematically generating and evaluating hypotheses without interruption. This continuous operation accelerates discovery while maintaining consistent application of expert knowledge through automated reasoning.

AI summary
An artificial intelligence engine for directed hypothesis generation and ranking uses multiple heterogeneous knowledge graphs integrating disease-specific multi-omic data specific to a patient or cohort of patients. The engine also uses a knowledge graph representation of ‘what the world knows’ in the relevant bio-medical subspace. The engine applies a hypothesis generation module, a semantic search analysis component to allow fast acquiring and construction of cohorts, as well as aggregating, summarizing, visualizing and returning ranked multi-omic alterations in terms of clinical actionability and degree of surprise for individual samples and cohorts. The engine also applies a moderator module that ranks and filters hypotheses, where the most promising hypothesis can be presented to domain experts (e.g., physicians, oncologists, pathologists, radiologists and researchers) for feedback. The engine also uses a continuous integration module that iteratively refines and updates entities and relationships and their representations to yield higher quality of hypothesis generation over time.
