DIAL-KG: Schema-Free Incremental Knowledge Graph Construction via Dynamic Schema Induction and Evolution-Intent Assessment
arXiv:2603.20059v1 Announce Type: new Abstract: Knowledge Graphs (KGs) are foundational to applications such as search, question answering, and recommendation. Conventional knowledge graph construction methods are predominantly static, rely ing on a single-step construction from a fixed corpus with a prede f ined schema.

Extensive experiments demon strate that our framework achieves state-of-the-art (SOTA) performance in the quality of both the constructed graph and the induced schemas.
Executive Summary
DIAL-KG is a novel framework for incremental knowledge graph construction, addressing limitations of conventional methods. The framework operates in a three-stage cycle: Dual-Track Extraction, Governance Adjudication, and Schema Evolution. Extensive experiments demonstrate its state-of-the-art performance in constructing high-quality graphs and inducing accurate schemas. This framework has significant implications for applications reliant on knowledge graphs, such as search, question answering, and recommendation systems. Its ability to adapt to dynamic data and evolve schemas makes it a valuable tool for real-world scenarios.
