Properties (Qualia)

Introduction

The term “qualia” originated in philosophy of mind to describe subjective sensory experiences. In computational linguistics, Pustejovsky (1995) redefined it as a structural framework to describe objects by combining objective properties with functional and generative aspects. This work was foundational for natural language processing and AI, as it provided a systematic way for machines to understand and generate context-dependent meanings of words and concepts. The Extended Matrix further develops this structured approach for Cultural Heritage documentation needs, maintaining its compatibility with computational processing while specializing it for the domain’s requirements.

While Pustejovsky’s original framework (Formal, Constitutive, Telic, and Agentive roles) provides valuable theoretical foundations, the Extended Matrix adopts a more specialized structure optimized for Cultural Heritage documentation.

5. Contextual Qualia

Administrative Qualia

Implementation in s3Dgraphy

The Extended Matrix qualia framework is implemented in the s3Dgraphy library through a structured JSON schema that provides standardized definitions, controlled vocabularies, and mappings to established standards. The complete schema can be found in the s3Dgraphy library documentation [link to be provided].

Temporal Perception System

The Extended Matrix introduces the ActorNode concept to manage temporal perceptions:

img/nodes/actor_node.png

An ActorNode represents an individual or group whose interpretation of properties is being recorded. This allows documentation of how properties were perceived at different times by different observers.

Example

A temple column’s significance might be interpreted differently:

Ancient Priest (1st century CE)
  • Telic: Sacred support of temple structure

  • Symbolic: Connection between earth and heavens

Medieval Chronicler (12th century)
  • Telic: Reminder of pagan past

  • Symbolic: Example of ancient craftsmanship

Modern Archaeologist (21st century)
  • Telic: Evidence of construction techniques

  • Symbolic: Indicator of economic resources
