texture-frames · trigger-identification head

The trigger-identification stage of texture-frames, a fast FrameNet semantic-frame parser. A per-token classifier (O / TRIGGER) that finds the words in a sentence that evoke a frame.

It fine-tunes microsoft/deberta-v3-large on FrameNet 1.7 (via NLTK) with the Open-Sesame document splits, scored with the upstream word-level F1 so it is directly comparable to prior work.

This is one of three stages. Use it through the package rather than alone; the pipeline chains trigger → frame → arguments.

Usage

pip install git+https://github.com/texturejc/Texture_Frames

from texture_frames import FrameParser
parser = FrameParser()   # downloads all three heads on first use
for ann in parser.parse("The chef gave food to the customer ."):
    print(ann.trigger, "->", ann.frame)
# gave -> Giving

A standard AutoModelForTokenClassification, so it also loads directly with transformers — but the package handles the word-level alignment (a trigger_bias lever trades precision for recall).

Results

Open-Sesame test split, word-level F1 (same metric as the T5 baseline):

Metric	This head	T5 baseline
Trigger F1	0.750	0.735
Speed	single forward pass (~50–60 ms)	3 beam-search passes

Ahead of the baseline, and ~3–4× faster (no autoregressive decoding).

Training

microsoft/deberta-v3-large, AdamW lr 1e-5, warmup 0.06, weight decay 0.01, batch 16, max length 320, bf16, 5 epochs. Data: FrameNet 1.7 (NLTK), Open-Sesame splits. See the repo for details.

Licence

Code (the package): MIT. Weights: trained on FrameNet 1.7, which carries its own academic-use terms — review them before redistributing.
