Company Intelligence: Why MARIA OS Is Not an AI Tool but the Operating System for Organizational Judgment
From memory and decision cards to strategic simulation, this is the architecture that turns AI Office from labor automation into an organization that learns
Most AI deployments improve local productivity but fail to compound into institutional intelligence. This article defines Company Intelligence as the closed loop of memory, decision, feedback, and governance, then explains how MARIA OS encodes that loop into company memory, executable decisions, agent performance systems, reflection pipelines, knowledge graphs, and strategic simulation.
Company Intelligence: なぜMARIA OSはAIツールではなく、会社の知能をつくるOSなのか
AI Officeの価値は作業自動化ではなく、会社が記憶し、判断し、学習し、自己改善する閉ループを持てるかで決まる
多くのAI導入は局所的な生産性を改善しても、企業固有の知能には積み上がらない。本稿は、Company Intelligence を Memory・Decision・Feedback・Governance の閉ループとして定義し、MARIA OS がそれを Company Memory、Decision Card、Task Intelligence、Agent Performance、Knowledge Graph、Strategic Simulation へどう実装するかを解説する。
Knowledge Graph Construction from Decision Audit Trails: Entity Resolution and Temporal Edge Weighting for Governance Traceability
Transforming immutable decision records into queryable knowledge structures with principled temporal decay and cross-agent entity resolution
Enterprise governance platforms generate large audit trails that encode organizational decision-making, but those records are often difficult to query across multi-hop relationships. This paper presents a formal framework for constructing knowledge graphs from decision logs, including entity-resolution methods for noisy multi-agent audit data, temporal-decay functions for relevance-aware edge weighting, and compliance-oriented subgraph extraction. Experiments on MARIA OS audit corpora report 91.3% entity-resolution F1 across overlapping agent zones and 2.7x faster compliance-query response than relational baselines.
Knowledge Graph Embedding for Agent Competence Assessment: Translational Distance Models in Responsibility Space
Mapping agents, decisions, and outcomes into continuous vector spaces to quantify competence through translational-distance geometry
Assessing AI-agent competence in enterprise governance requires moving beyond binary success/failure metrics toward a continuous, context-sensitive model. This paper introduces a knowledge-graph-embedding framework based on translational-distance models (TransE, RotatE) adapted to the MARIA OS responsibility space. Agents, decisions, and outcomes are embedded in a shared vector space, where competence is measured by distance between context-translated agent embeddings and ideal outcome embeddings. We formalize the geometry, derive governance-aware loss functions, analyze convergence behavior, and show that KGE-derived competence scores correlate with held-out success probability at r = 0.89.
Knowledge Graph Completion Under Partial Observability: Predicting Missing Responsibility Edges in Enterprise Governance Graphs
Tensor-factorization methods for link prediction in incomplete governance graphs, with theoretical accuracy bounds across observability regimes
Enterprise knowledge graphs are inherently incomplete: undocumented responsibility links, informal decision chains, and cross-zone dependencies leave traceability gaps. This paper formulates governance-graph completion as a tensor-factorization problem under partial observability. We model the graph as a binary three-way tensor X in {0,1}^{n x n x r} (entities x entities x relations), apply CP decomposition to predict missing links, and derive theoretical accuracy bounds as a function of observability rate rho. On MARIA OS governance graphs, CP decomposition recovers 84.2% of withheld responsibility edges at 70% observability and surfaces 31 previously undocumented responsibility gaps in production.
Causal-Temporal Knowledge Graph for AI Governance: Path-Specific Responsibility Attribution
A deep research framework for path-specific accountability, time-aware causality, and audit-grade explanation in enterprise AI
A temporal responsibility graph enables path-level causal attribution and faster, more reproducible root-cause analysis.
Graph RAG Matrix Modeling and Stable Hop Count Derivation
Spectral analysis of adjacency matrices reveals the optimal diffusion depth that maximizes signal-to-noise ratio in knowledge graph retrieval
Graph-based Retrieval Augmented Generation traverses knowledge graphs to gather context for language-model prompts. Each additional hop `h` in `A^h` can add useful context but also amplify noise through irrelevant paths. This paper models diffusion as matrix exponentiation with decay, derives signal-to-noise behavior by hop count using spectral decomposition, and identifies an optimal hop count `h*`. Across four enterprise knowledge graphs, the derived `h*` reduced hallucination rate by 43% versus fixed-depth traversal.
