Assertion: sentence seeks or gives clarification

This classifier was trained for EduBehaviors: Assertion-based schemas for auditable dialogue coding and is usable through the Python package EduBehaviors-kit. This classifier was trained on an LLM-annotated subset of teacher utterances from the TalkMoves Dataset. See the Datasets section below for more information.


Training Details

Datasets

This model's columns are assertion_sentence_seeks_or_gives_clarification and split_sentence_seeks_or_gives_clarification.

Base rate (share of rows labeled as True): 16.7% overall — 16.6% train, 17.4% dev, 16.6% test.

Labels and annotation

Labels were generated with LLM annotators. Krippendorff's alpha for this assertion is 0.270.

Limitations

  • Labels come from LLM annotators, not human coders. Agreement with Krippendorff's Alpha is 0.270; this is poor.This model's predictions and the underlying data are unreliable.
  • Trained on teacher utterances only. Behaviour on student speech is untested.

How to Use

Message Structure

The model was trained on text built as:

{utterance}

The utterance is passed through as-is.

Running instructions

bash
pip install setfit
python
from setfit import SetFitModel

model = SetFitModel.from_pretrained("StanfordSCALE/assertion_sentence_seeks_or_gives_clarification")

text = 'Now were not talking about clothes but like model a problem'
model.predict([text])        # -> array([1]) when the assertion holds
model.predict_proba([text])  # -> [[P(no), P(yes)]]
