Models
Next, the retrieval encoder identifies synonyms by evaluating phrase pairs within the KG, detecting those with vector similarity above a predefined threshold, and adding synonym edge between such pair. This process enables the KG to link synonyms across different passages, facilitating the integra- tion of both old and new knowledge during learning.
Synonym-based linking in knowledge graphs risks flattening creative connections into mechanical similarity. Meaningful ontological relationships require personal insight and contextual judgment — not all structurally equivalent links are conceptually useful.
