Abstract

fetched live from OpenAlex

Lexical cues are linguistic expressions that can signal the presence of a rhetorical relation.However, such cues can be ambiguous as they may signal more than one relation or may not always function as a relation indicator.In this study, we first conduct a corpus-based analysis to derive a set of n-grams as potential lexical cues.These cues are then utilized in graph-based probabilistic models to determine the syntactic context in which the cue is signaling the presence of a particular relation.Evaluation results are reported for various cues of the CIRCUMSTANCE relation, confirming the value of syntactic features for the task of cue disambiguation in the context of Rhetorical Structure Theory.Moreover, using a graph to encode syntactic information is shown to be a more generalizable and effective approach compared to the direct usage of syntactic features.

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.
