Editing Knowledge Graphs (section)

== <span style="color: #FFFFFF;">Creating</span> ==
Designing a domain knowledge graph from scratch:

'''1. Domain scoping and ontology design'''
<syntaxhighlight lang="text">
Define scope: What entities matter? What relationships?
    ↓
Review existing ontologies: Schema.org, biomedical ontologies (SNOMED, MeSH), industry standards
    ↓
Design ontology: entity types, relation types, cardinality constraints
    ↓
Define naming conventions and URI scheme
    ↓
Validate with domain experts: are these the right concepts?
</syntaxhighlight>

'''2. Knowledge acquisition pipeline'''
<syntaxhighlight lang="text">
Structured sources (databases, APIs, spreadsheets)
    ↓ [Direct mapping to triples]
    
Unstructured sources (text documents, web pages)
    ↓ [NER → entity linking → relation extraction → triple extraction]
    ↓ [Confidence scoring: filter low-confidence triples]
    ↓ [Human validation of uncertain triples]
    
Semi-structured sources (tables, infoboxes)
    ↓ [Table understanding + header interpretation]
    ↓
[Deduplication + entity alignment]
    ↓
[Knowledge base population]
