Abstract

This paper presents GISMOL (General Intelligent System Modelling Language), a Python-based framework implementing Constrained Object Hierarchies (COH)—a neuroscience-inspired theoretical framework for Artificial General Intelligence (AGI). COH and GISMOL together provide a unified language for modelling and implementing intelligent systems across diverse domains including healthcare, manufacturing, finance, and governance. The framework bridges symbolic AI and neural computation through its core architecture of constraint-aware objects with embedded neural components, hierarchical reasoning capabilities, and natural language integration. We demonstrate how GISMOL translates COH’s formal 9-tuple representation into executable systems with six comprehensive case studies, showing its versatility in modelling complex intelligent behaviors while maintaining theoretical rigor. The implementation includes specialized modules for neural integration, multi-domain reasoning, and natural language processing, all built around the COHObject abstraction that encapsulates intelligence as constrained hierarchical structures.

1. Introduction

The pursuit of Artificial General Intelligence (AGI) represents one of the most ambitious goals in computer science and cognitive science [1]. Unlike narrow AI systems optimized for specific tasks, AGI aims to achieve human-level versatility, adaptability, and reasoning across multiple domains [2]. Current approaches to AGI development face fundamental challenges, including the integration of neural learning with symbolic reasoning, the maintenance of safety and ethical constraints, and the creation of systems that can generalize beyond their training distributions [3].
Traditional deep learning approaches, while powerful for pattern recognition, struggle with explicit reasoning, constraint satisfaction, and interpretability [4]. Conversely, symbolic AI systems excel at logical inference and knowledge representation but lack the learning capabilities and robustness to uncertainty of neural approaches [5]. This dichotomy has led to renewed interest in neuro-symbolic integration, which seeks to combine the strengths of both paradigms [6].
GISMOL addresses these challenges through its foundation in Constrained Object Hierarchies (COH), a theoretical framework that models intelligent systems as hierarchical compositions of objects subject to multi-domain constraints [7]. COH extends beyond typical neuro-symbolic approaches by embedding constraints directly within the system architecture through identity, trigger, and goal constraints monitored by autonomous daemons [8].
Scope and contributions of this paper (development-stage):
  • A formal presentation of the COH theoretical framework and its neuroscience grounding.
  • A description of the design goals and initial API of GISMOL, a prototype Python library for COH.
  • Six conceptual case studies and code snippets illustrating intended usage patterns and cross-domain applicability.
  • A preliminary comparison with existing approaches to indicate potential advantages and gaps.
  • A development roadmap, implementation strategies, and evaluation plan suitable for future empirical validation.
Disclaimer. GISMOL is not yet a mature production framework. The API is subject to change, and examples provided are prototypes or simulated demonstrations, not deployed systems.

2. Literature Review

2.1. Symbolic AI and Knowledge Representation

Early AI research focused heavily on symbolic approaches, with systems like SOAR [9] and ACT-R [10] providing cognitive architectures for representing knowledge and reasoning. These systems excelled at tasks requiring explicit rule-based reasoning but struggled with perception, learning, and handling uncertainty [11]. More recent approaches like TensorLog [12] have attempted to bridge symbolic and neural representations through differentiable inference but often lack comprehensive constraint management capabilities.

2.2. Neural Networks and Deep Learning

The resurgence of neural networks, particularly through deep learning architectures [13], has revolutionized fields like computer vision, natural language processing, and reinforcement learning [14]. However, these systems typically operate as “black boxes” with limited interpretability and difficulty incorporating explicit constraints or symbolic knowledge [15].

2.3. Neuro-Symbolic Integration

Recent work in neuro-symbolic AI has explored various integration strategies. DeepProbLog [16] combines probabilistic logic programming with neural networks, while Neural Theorem Provers [17] use differentiable reasoning. Neurosymbolic Concept Learners [18] integrate perception with reasoning. However, these approaches often lack the hierarchical organization and comprehensive constraint system provided by COH [19].

2.4. Cognitive Architectures and AGI

Cognitive architectures like LIDA [20] and CLARION [21] attempt to model human cognition more comprehensively but often lack practical implementation frameworks for real-world applications. GISMOL builds on these ideas while providing a concrete, executable modeling language.

2.5. Constraint Satisfaction and Optimization

Constraint programming [22] and constraint satisfaction problems [23] provide formalisms for representing and solving constrained systems. GISMOL extends these ideas through its hierarchical constraint system and integration with neural components for adaptive constraint resolution.

3. Introducing Constrained Object Hierarchies (COH)

3.1. Formal Definition

Constrained Object Hierarchies (COH) provides a formal framework for modeling general intelligent systems as 9-tuple structures:
O = (C, A, M, N, E, I, T, G, D)
Where:
C (Components): Sub-objects forming a compositional hierarchy, enabling complex system decomposition.
A (Attributes): State variables describing object properties, representing system state.
M (Methods): Executable actions or behaviors, implementing system functionality.
N (Neural Components): Adaptive models for learning and inference, providing statistical learning capabilities.
E (Embedding): Neural components for semantic representation, enabling knowledge integration.
I (Identity Constraints): Fundamental structural and logical rules, defining system invariants.
T (Trigger Constraints): Event-condition-action mechanisms, enabling reactive behavior.
G (Goal Constraints): Optimization objectives guiding intelligent behavior, providing purposeful direction.
D (Constraint Daemons): Real-time monitors enforcing constraints, ensuring continuous compliance.

3.2. Neuroscience Grounding

COH draws inspiration from hierarchical organization in biological neural systems [24], where different brain regions specialize in different functions while maintaining integrated operation. The hippocampus provides episodic memory (attributes), the prefrontal cortex implements executive functions (methods), and basal ganglia mediate reinforcement learning (goal constraints) [25]. Constraint daemons parallel regulatory mechanisms in biological systems that maintain homeostasis [26].

3.3. Theoretical Significance

COH provides several theoretical advances:
  • Unified Representation: Integrates symbolic, neural, and constraint-based representations.
  • Hierarchical Composition: Supports arbitrary decomposition while maintaining constraint propagation.
  • Multi-domain Constraints: Accommodates biological, physical, temporal, and other domain-specific constraints.
  • Real-time Monitoring: Constraint daemons provide continuous validation.
  • Adaptive Optimization: Goal constraints guide learning toward multiple objectives.

4. Structure of GISMOL

Development status. GISMOL is a prototype library; several modules are partially implemented, and others are in design or stubbed form. APIs described below represent the intended interface and may evolve.
GISMOL aims to implement COH theory as a Python library with four main modules:

4.1. Core Module (gismol.core)

Core Module establishes the foundational COHObject class and its supporting infrastructure.
Current prototypes include:
  • COHObject: Base class for intelligent system components.
  • ConstraintSystem: Manages constraint evaluation and resolution.
  • ConstraintDaemon: Autonomous agents for real-time constraint monitoring.
  • COHRepository: Manages object collections and relationships.

4.2. Neural Module (gismol.neural)

The Neural Module designs constraint-aware neural components that integrate with COH objects:
  • NeuralComponent: Base class combining nn.Module with COHObject.
  • EmbeddingModel: Generates semantic representations of objects and text.
  • ConstraintAwareOptimizer: Optimizers that respect constraints.
  • Specialized models for classification, regression, and generation (in progress).

4.3. Reasoners Module (gismol.reasoners)

Provides domain-specific engines for constraint evaluation:
  • BaseReasoner: Fallback implementation with robust error handling.
  • Domain-specific reasoners (Biological, Physical, Geometric, etc.).
  • Advanced reasoning systems (Causal, Probabilistic, Temporal, etc.).
  • Registry pattern for dynamic reasoner discovery.

4.4. NLP Module (gismol.nlp)

Enables natural language understanding with constraint awareness:
  • COHDialogueManager: Manages conversations with constraint validation (prototype).
  • EntityRelationExtractor: Extracts knowledge from text into COHObjects (prototype).
  • Text2COH: Converts documents into hierarchical object structures (planned).
  • ResponseValidator: Ensures language generation respects constraints (planned).

4.5. COH-to-GISMOL Mapping

Table 1 shows the mapping between COH theoretical elements and GISMOL implementation constructs (design intent).

7. Modelling and Programming Examples

The following examples illustrate how various intelligent systems can be modelled with COH, and programmed with GISMOL into native Python applications. Because the supporting GISMOL library is still under development and yet to be released to the public, the GISMOL implementations are only meant to illustrate the semantics of the COH models of each intelligent system. If anyone wants to implement any of these intelligent systems with GISMOL, please contact the author directly.
