Entity Property

A Entity Property is an abstract entity of another entity (in a property-of relation) that describes some innate aspect of the entity.

• Context:
  • It can typically describe Entity State through property values.
  • It can typically characterize Entity Identity via distinguishing features.
  • It can typically differentiate Entity Type based on defining characteristics.
  • It can typically classify Entity Instance using classification propertys.
  • It can typically represent Entity Aspect in conceptual models.
  • ...
  • It can often be measured through Property Measurement using property evaluation techniques.
  • It can often be compared with Property Value from other entitys.
  • It can often be represented by Property Descriptor in knowledge representation systems.
  • It can often be organized into Property Hierarchy for property classification.
  • It can often undergo Property Change during entity evolution.
  • ...
  • It can range from being a Physical Entity Property to being a Mental Concept Property, depending on its property nature.
  • It can range from being a Simple Entity Property to being a Complex Entity Property, depending on its structural complexity.
  • It can range from being a Intrinsic Entity Property to being a Relational Entity Property, depending on its dependency type.
  • It can range from being a Concrete Entity Property to being an Abstract Entity Property, depending on its abstraction level.
  • It can range from being a Static Entity Property to being a Dynamic Entity Property, depending on its change frequency.
  • ...
  • It can be referenced by a Data Item Attribute in data models.
  • It can be represented by a Property Symbol in formal notations.
  • It can be organized within a Property Taxonomy for knowledge organization.
  • It can be transformed through Property Mapping for data integration.
  • It can be constrained by Property Restriction for validation purposes.
  • ...
• Examples:
  • Physical Entity Property Categories, such as:
    • Material Entity Propertys, such as:
      • Physical Object Propertys, such as:
        • Size Propertys (e.g., length, width, height).
        • Mass Propertys (e.g., weight, density).

        • Thermal Propertys (e.g., temperature, heat capacity).
        • Mechanical Propertys (e.g., elasticity, tensile strength).
    • Living Entity Propertys, such as:
      • Biological Propertys (e.g., species, genetic makeup, metabolic rate).
      • Physiological Propertys (e.g., heart rate, blood pressure, neural activity).
      • Morphological Propertys (e.g., anatomical structure, cellular organization).
  • Conceptual Entity Property Categories, such as:
    • Cognitive Entity Propertys, such as:
      • Mental State Propertys (e.g., belief, desire, intention).
      • Cognitive Ability Propertys (e.g., intelligence, creativity, memory capacity).
      • Knowledge Propertys (e.g., expertise level, knowledge domain, conceptual understanding).
    • Abstract Concept Propertys, such as:
      • Concept Propertys (e.g., concept clarity, concept utility, concept complexity).
      • Theory Propertys (e.g., explanatory power, predictive accuracy, theoretical parsimony).
      • Idea Propertys (e.g., idea originality, idea practicality, idea coherence).
  • Digital Entity Property Categories, such as:
    • Data Entity Propertys, such as:
      • Data Record Propertys, such as data record attributes (e.g., data field name, data type, data value).
      • Dataset Propertys (e.g., data completeness, data accuracy, data timeliness).
      • Data Structure Propertys (e.g., structure type, structural complexity, access efficiency).
    • Software Entity Propertys, such as:
      • Code Propertys (e.g., code complexity, code modularity, code performance).
      • Algorithm Propertys (e.g., time complexity, space complexity, algorithm stability).
      • System Propertys (e.g., system reliability, system security, system scalability).
  • Social Entity Property Categories, such as:
    • Social Agent Propertys, such as:
      • Person Propertys (e.g., personality trait, skill level, social role).
      • Organization Propertys (e.g., organizational structure, organizational culture, organizational capability).
      • Community Propertys (e.g., community cohesion, community diversity, community resilience).
    • Social Relation Propertys, such as:
      • Relationship Propertys (e.g., relationship strength, relationship duration, relationship type).
      • Network Propertys (e.g., network density, network centrality, network diameter).
      • Interaction Propertys (e.g., interaction frequency, interaction quality, interaction pattern).
  • ...
• Counter-Examples:
  • A Legal Property (e.g., land, building, or possession), which represents ownership rights rather than innate entity characteristics.
  • A Property-Value Assignment, which is the act of associating a property with a specific value rather than the property itself.
  • An Entity Relation, which describes a connection between entities rather than an intrinsic aspect of a single entity.
  • An Entity Operation, which represents an action that can be performed on an entity rather than a characteristic of the entity.
  • An Entity Classification, which is the categorization of an entity based on its properties rather than being a property itself.

  • In modern philosophy, mathematics, and logic, a property is an attribute of an object; a red object is said to have the property of redness. The property may be considered a form of object in its own right, able to possess other properties. A property however differs from individual objects in that it may be instantiated, and often in more than one thing. It differs from the logical/mathematical concept of class by not having any concept of extensionality, and from the philosophical concept of class in that a property is considered to be distinct from the objects which possess it. Understanding how different individual entities (or particulars) can in some sense have some of the same properties is the basis of the problem of universals. The terms attribute and quality have similar meanings.

  • The redness of a red apple, or more to the point, the redness all red things share, is a property. One could also call it an attribute of the apple. Very roughly put, a property is just a quality that describes an object. This will not do as a definition of the word 'property' because, like 'attribute', 'quality' is a near-synonym of 'property'. But these synonyms can at least help us to get a fix on the concept we are talking about. Whenever one talks about the size, color, weight, composition, and so forth, of an object, one is talking about the properties of that object. Some — though this is a point of severe contention in the problem of universals – believe that properties are beings; the redness of all apples is something that is. To deny that universals exist is the scholastic variant of nominalism.

    Note that the color red is an objective property of an object. The intrinsic property is that it reflects radiation (including light) in a certain way. A human perceives that as the color red in his or her brain. An object thus has two types of properties, intrinsic (physical) and objective (observer specific).
