Abstract

fetched live from OpenAlex

Inter-sentence relation extraction deals with a number of complex semantic relationships in documents, which require local, non-local, syntactic and semantic dependencies.Existing methods do not fully exploit such dependencies.We present a novel inter-sentence relation extraction model that builds a labelled edge graph convolutional neural network model on a document-level graph.The graph is constructed using various inter-and intra-sentence dependencies to capture local and non-local dependency information.In order to predict the relation of an entity pair, we utilise multi-instance learning with bi-affine pairwise scoring.Experimental results show that our model achieves comparable performance to the state-of-the-art neural models on two biochemistry datasets.Our analysis shows that all the types in the graph are effective for inter-sentence relation extraction.

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.
