HyperPersona: A Multi-Level Hypergraph Framework for Text-Based Automatic Personality Prediction

HyperPersona is a multi‑level hypergraph framework that models the hierarchical structure of text—document, sentence, and word—using hyperedges for documents and sentences and nodes for words. It employs a transformer‑based graph encoder to capture interactions across these linguistic layers, producing context‑sensitive, structurally grounded features for automatic personality prediction. Experiments on the Big Five personality dimensions demonstrate that HyperPersona, relying solely on text, outperforms state‑of‑the‑art baselines by effectively integrating multi‑level linguistic cues.
