Abstract
Automatic Key-phrase Extraction to Support the Understanding of Infrastructure Disaster Resilience Xuan Lv, Syed Ahnaf Morshed and Lu Zhang Pages 1276-1281 (2019 Proceedings of the 36th ISARC, Banff, Canada, ISBN 978-952-69524-0-6, ISSN 2413-5844) Abstract: Preventing natural disasters from causing substantial social-economic damages relies heavily on the disaster resilience of the nation's critical infrastructure. According to the National Academy of Sciences, research on understanding and analyzing the disaster resilience of our infrastructure systems is a "national imperative". To address this need, this paper proposes an automatic keyphrase extraction methodology to extract relevant phrases on disaster resilience from documents in infrastructure domain. In developing the proposed methodology, a document collection including research papers and public reports are prepared. Noun phrases are first extracted from every sentence in the collection and form the candidates for keyphrases following a filtering procedure. Each candidate phrase is then represented as a global semantic vector and a local semantic vector. To select relevant phrases on disaster resilience, a semantic similarly measure is proposed to incorporate the semantics of candidate phrases in both the general and infrastructure domain. Ten physical resilience concepts from a pre-developed community resilience hierarchy is selected as the target concepts to evaluate the performance of the proposed methodology. When evaluated on the document collection, the proposed methodology achieved 66% of precision at top 20 extracted keyphrases on average.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
