Aevum Encyclopedia › Semantics & Knowledge Graph

Semantic Architecture & Knowledge Graph

Explore how Aevum structures, contextualizes, and interconnects human knowledge using formal ontologies, RDF standards, and machine-readable semantics.

Overview: Structuring Meaning

Unlike traditional encyclopedias that store flat articles, Aevum Encyclopedia treats knowledge as a dynamic semantic network. Every concept, entity, event, and relationship is modeled using standardized ontologies, enabling machines to reason over data and humans to discover non-obvious connections across disciplines.

Our semantic layer operates on four foundational principles:

Principle 01

🔗 Interlinkability

Entities are universally identifiable via persistent URIs and cross-referenced across linguistic and disciplinary boundaries.

Principle 02

🧩 Formal Ontology

Class hierarchies, properties, and constraints are defined using OWL 2 RL/RPF, ensuring logical consistency and machine reasonability.

Principle 03

📊 Multi-Layer Context

Semantics are stratified into lexical, conceptual, relational, and evidentiary layers, each serving distinct query and inference patterns.

Principle 04

🤖 AI-Ready Semantics

Dense vector embeddings are aligned with graph topology, enabling hybrid retrieval (keyword + graph + embedding) for high-fidelity answers.

Data Model & Entity Types

The Aevum Knowledge Graph (AEKG) follows a property graph + RDF hybrid model. Core entity types are mapped to Schema.org, Wikidata, and domain-specific ontologies where applicable.

Entity Class Primary Properties Example URI Pattern
ae:Concept label, description, category, aliases https://aevum.io/entity/concept/quantum_entanglement
ae:Person birthDate, affiliations, works, influences https://aevum.io/entity/person/albert_einstein
ae:Event startTime, endTime, location, participants https://aevum.io/entity/event/solway_conference
ae:Place geoCoordinates, hierarchy, historicalNames https://aevum.io/entity/place/princeton_nj
ae:Publication doi, journal, authors, citationCount https://aevum.io/entity/pub/doi-10.1103/physrev.47.777

Visualizing Semantic Relationships

Below is a simplified representation of how entities connect through typed, directional edges with provenance metadata.

ae:Person
Marie Curie
ae:authored
ae:Publication
Radioactivity Theory
ae:explains
ae:Concept
Nuclear Decay

* Edges carry confidence scores, temporal validity, and source citations

Technical Standards & Interoperability

Aevum publishes semantic data in open, W3C-compliant formats. All exports support standard RDF serializations and knowledge graph APIs.
