Combining structured knowledge from knowledge graphs with the statistical patterns language models learn from text — and what that combination buys you for evaluation.
Li's KEG Lab at Tsinghua has been the methodological home for one of the longest-running lines on knowledge-graph-augmented language models — OpenKE for KG embeddings, KEPLER for combining KG and language pretraining, and a research thread that led, via Zhipu, to the ChatGLM open LLM line. The throughline is a commitment to language models that have an external structured-knowledge anchor as well as their parametric memory, which makes the resulting systems easier to audit — you can ask the model and you can ask the KG separately, then compare. For ai100, which audits brand-mention behavior, the KG-augmented evaluation tradition is the closest precedent for separating "what the model says" from "what its sources support".
