# TACTBench Demonstration Samples
This repository contains five full-context demonstration examples from
TACTBench. It does not contain the TACT training set or the remaining hidden
TACTBench evaluation set. The samples use the same full-history representation
as the benchmark evaluation and illustrate direct correction, error
explanation, guided revision, clarification checking, affective feedback, and
retry elicitation.
## Data
- `data/demo.jsonl`: five complete benchmark contexts selected from five
distinct tutoring conversations.
- Each row contains the full visible dialogue history before the target teacher
turn, the reference teacher response, and its tutor-strategy label or labels.
These rows are demonstration examples and must not be included in future hidden
benchmark scoring. Historical paper results were computed on the original
78-item benchmark before these examples were released.
## Schema
- `sample_id`: stable identifier for this demonstration release.
- `source_item_id`: provenance identifier in the internal benchmark.
- `split`: always `demo`.
- `context_scope`: always `full_history`.
- `history_variant`: always `full_context`, matching the paper evaluation.
- `full_history_turn_count`: number of visible dialogue turns before the target.
- `dialogue_history`: ordered teacher and student turns.
- `reference_teacher_response`: the authentic next teacher turn.
- `teacher_taxonomy_labels`: pedagogical function labels for the response.
- `source_full_context_word_count`: descriptive word count across the complete
visible dialogue history and reference response.
## Source and Terms
The dialogue excerpts are derived from the Teacher-Student Chatroom Corpus
version 2 (TSCC v2). TSCC is distributed by the University of Cambridge under
its own user agreement for non-commercial research and educational use. This
sample repository does not grant rights to the complete TSCC corpus. Researchers
who need the source corpus should apply through the official TSCC access form:

## Citation
Please cite both the TACT paper and the TSCC v2 paper when using these samples.
