Abstract

fetched live from OpenAlex

Relation prediction on knowledge graphs (KGs) attempts to infer the missing links between entities.Most previous studies are limited to the transductive setting where all entities must be seen during the training, making them unable to perform reasoning on emerging entities.Recently, the inductive setting is proposed to handle the entities in the test phase to be unseen during training, However, it suffers from the inefficient reasoning under the enclosing subgraph extraction issue and the lack of effective entity-independent feature modeling.To this end, we propose a novel Query Adaptive Anchor Representation (QAAR) model for inductive relation prediction.First, we extract one opening subgraph and perform reasoning by one time for all candidate triples, which is more efficient when the number of candidate triples is large.Second, we define some query adaptive anchors which are independent on any specific entity.Based on these anchors, we take advantage of the transferable entityindependent features (relation-aware, structureaware and distance features) that can be used to produce entity embeddings for emerging unseen entities.Such entity-independent features is modeled by a query-aware graph attention network on the opening subgraph.Experimental results demonstrate that our proposed QAAR outperforms state-of-the-art baselines in inductive relation prediction task.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
