Overview

slipnet.py implements the Slipnet, a key component of the Copycat system that represents the conceptual network of relationships between different concepts. It manages a network of nodes (concepts) and links (relationships) that are used in analogical reasoning.

Core Components

• Slipnet class: Main class that manages the conceptual network
• Network of Slipnode objects representing concepts
• Network of Sliplink objects representing relationships

Key Features

• Manages a network of conceptual nodes and their relationships
• Handles activation spreading between nodes
• Supports both slip and non-slip links
• Implements various types of relationships:
  • Letter categories
  • String positions
  • Alphabetic positions
  • Directions
  • Bond types
  • Group types
  • Other relations

Node Types

• Letters (a-z)
• Numbers (1-5)
• String positions (leftmost, rightmost, middle, single, whole)
• Alphabetic positions (first, last)
• Directions (left, right)
• Bond types (predecessor, successor, sameness)
• Group types (predecessorGroup, successorGroup, samenessGroup)
• Categories (letterCategory, stringPositionCategory, etc.)

Link Types

• Slip links (lateral connections)
• Non-slip links (fixed connections)
• Category links (hierarchical connections)
• Instance links (specific examples)
• Property links (attributes)
• Opposite links (antonyms)

Dependencies

• Requires slipnode and sliplink modules
• Used by the main copycat module

Notes

• The network is initialized with predefined nodes and links
• Activation spreads through the network during reasoning
• Some nodes are initially clamped to high activation
• The network supports both hierarchical and lateral relationships
• The system uses conceptual depth to determine link strengths
