Acronym
SiGNaL³ - Simple Strategic Superior Graph Navigation Language
From SiGNaL to SiGNaL³: The RAG Revolution
Building on the foundation of SiGNaL (Simple Graph Navigation Language), SiGNaL³ applies Retrieval Augmented Generation cleverly to transform knowledge graph exploration from static navigation into intelligent, context-aware journeys.
Wikidata Tour: Earth, Moon and Human Consciousness
As an example we will take a tour of Wikidata starting in alignment with the original SiGNaL article of 2018.
The Earth-Moon Relation
Earth (Q2) and Moon (Q405) have a relation that can be described as an edge in a knowledge graph.
Superior Visualization Through LLMs
When visiting the node Earth of the knowledge graph, an appropriate visualization of the node and relevant possible paths/edges should be visualized. With the power of state-of-the-art Large Language Models, the selection of the visualization should be feasible in a way that is superior to traditional knowledge graph exploring approaches.
The Earthrise Symbol
The Earthrise (Q843864) picture is a symbol for the relation between Moon, Earth and Human (Q5). When mankind was capable of taking this viewpoint it was a groundbreaking moment in human history and the picture is iconic in the semiotic sense.
Content
Triples of two nodes linked by a relation are the core elements of knowledge graphs (KGs). Navigating such a graph in a human friendly / natural / simple way is mandatory for successful usage of such knowledge graphs.
Strategic Subgraph Availability
The strategic move now is to make sure relevant subgraphs are readily available to fulfill needs of projects based on the use cases and use case scenarios of a project.
Such scenarios fortunately can be described with sets of situation/action/expected result descriptions:
- A situation describes a relevant subgraph in a concrete state
- The action describes what a system should be offering as an API working on the situation subgraph
- The expected result is describing the result subgraph potentially with modifications that have been applied
Natural Language to Graph Traversal
Natural language use case descriptions may be transformed to augmented knowledge graph traversals this way. The journey through the knowledge graph may be interactive.
Knowledge Graph Exploration Application
A first application is knowledge graph exploration. The traversal path and the human input gathered on the way may now be used to:
- Create a relevant subgraph
- Generate an abstract description of the subgraph that allows stakeholders to create a local copy
- Enable project stakeholders to work with the local copy by modifying and extending
- Provide synchronization of this local KG with the original KG (respecting privacy settings)
SiGNaL³ Tour Example: Earth to Human Consciousness
Starting from Earth (Q2):
Interactive Journey Elements
- Situation: User at Earth node, interested in human space exploration
- Action: SiGNaL³ RAG system identifies Moon→Apollo→Earthrise pathway as most meaningful
- Expected Result: User gains understanding of how space exploration changed human consciousness
Advantages Over Traditional Approaches
| Traditional KG Navigation | SiGNaL³ RAG-Enhanced Navigation |
|---|---|
| Manual node clicking | Intelligent pathway suggestions |
| All edges shown equally | Contextually relevant edges prioritized |
| Static visualizations | Dynamic, story-driven presentations |
| Technical interface | Human-friendly natural language interaction |
| No narrative context | Rich semiotic and historical context |
Use Case Scenarios
Research Discovery
- Situation: Researcher exploring climate change impacts
- Action: Start from Earth (Q2), RAG identifies pathways through atmosphere, greenhouse gases, temperature records
- Result: Curated subgraph of climate-related concepts with temporal relationships
Educational Tours
- Situation: Student learning about space exploration
- Action: Interactive tour from Earth→Moon→Mars with historical context
- Result: Engaging narrative connecting astronomical facts to human achievement
