We present a system for constructing ontology graphs from text using openweight large language models. Our approach combines structured prompting, predicate normalization, and structural filtering. Prompt ablation experiments show that explicit taxonomy rules and closed-world constraints improve graph quality. We also introduce a conservative ensemble that retains only triples shared by two prompt configurations. On the official test set, the selected ensemble achieves Graph Similarity scores of 0.3584, 0.4872, and 0.5162 under exact, fuzzy, and semantic matching.
