Abstract

fetched live from OpenAlex

Document-level relation extraction (DocRE)involves identifying relations between entities distributed in multiple sentences within a document.Existing methods focus on building a heterogeneous document graph to model the internal structure of an entity and the external interaction between entities.However, there are two drawbacks in existing methods.On one hand, anaphor plays an important role in reasoning to identify relations between entities but is ignored by these methods.On the other hand, these methods achieve crosssentence entity interactions implicitly by utilizing a document or sentences as intermediate nodes.Such an approach has difficulties in learning fine-grained interactions between entities across different sentences, resulting in sub-optimal performance.To address these issues, we propose an Anaphor-Assisted (AA) framework for DocRE tasks.Experimental results on the widely-used datasets demonstrate that our model achieves a new state-of-the-art performance.1

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
