DTScribe: Generating Models for Digital Twin Reporting using Local Large Language Models

Read the original on arXiv AI →

DTScribe automates the creation of digital twin reporting models by ingesting digital twin documents and producing both a conceptual architecture visualization and a reporting page. It extracts key details based on a twenty‑one‑characteristic framework, generates an Ontological Modeling Language description, and refines the artifact through loops involving local large language models and ontological reasoning. The study evaluates how architectural and parameter choices—such as using medium‑sized local models and multiple refinement loops—affect artifact quality, offering practical insights for practitioners.

SINT-Flow: Schema Integration using Large Language Model Workflows

SINT-Flow is a schema integration framework that uses five large language model (LLM) operators to automatically produce a unified schema from multiple input tables, even when those tables are denormalized and contain attributes for several entity types. The framework decomposes such tables into entity‑specific relations during integration. Evaluation on the newly introduced SINT‑Bench benchmark, using GPT‑5.2 and Qwen‑3.6‑27B, shows high performance with at least 97% completeness in entity type detection, 81% attribute detection, and an 84% F1‑score for schema mapping, while ablation studies confirm the benefits of self‑consistency and a review loop.

An Ontology-Guided, Deduplication-Aware Extraction Layer for Knowledge Graph Construction from Heterogeneous Documents

arXiv:2607. 28662v1 Announce Type: new Abstract: Large language models extract entities and relationships from unstructured documents fluently but inconsistently: type vocabularies fracture across documents, the same person surfaces under several name variants, relationships duplicate, and distinct individuals who share a name risk silent conflation.
