COMET-M: Reasoning about Multiple Events in Complex Sentences
Bibliographic record
Abstract
Understanding the speaker's intended meaning often involves drawing commonsense inferences to reason about what is not stated explicitly.In multi-event sentences, it requires understanding the relationships between events based on contextual knowledge.We propose COMET-M (Multi-Event), an eventcentric commonsense model capable of generating commonsense inferences for a target event within a complex sentence.COMET-M builds upon COMET (Bosselut et al., 2019), which excels at generating event-centric inferences for simple sentences, but struggles with the complexity of multi-event sentences prevalent in natural text.To overcome this limitation, we curate a Multi-Event Inference (MEI) dataset of 35K human-written inferences.We train COMET-M on the human-written inferences and also create baselines using automatically labeled examples.Experimental results demonstrate the significant performance improvement of COMET-M over COMET in generating multi-event inferences.Moreover, COMET-M successfully produces distinct inferences for each target event, taking the complete context into consideration.COMET-M holds promise for downstream tasks involving natural text such as coreference resolution, dialogue, and story understanding.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
