From 4f743e084086e00eed3cf6954362b1b1d353bebb Mon Sep 17 00:00:00 2001 From: egutierrez Date: Thu, 30 Apr 2026 16:52:46 +0200 Subject: [PATCH 1/2] feat(pipelines): extract_graph_hybrid (regex + GLiNER + GLiREL + LLM fallback) Pipeline en cascada que combina extract_iocs (regex, coste 0), GLiNER (zero-shot NER), GLiREL (zero-shot RE) y un fallback LLM opcional para chunks con baja confianza o pocas entidades. Devuelve listas concatenadas listas para deduplicate_entities/deduplicate_relations.
