POCAAffectClassification

Multi-label affect / emotion classification for English poetry (PoetryMTEB), derived from the POCA dataset (Khan, Hopkins & Gunes, ACII 2021).

Poems are annotated on the Geneva Emotion Wheel (20 discrete affects, intensity 0–10) via Mechanical Turk; we binarize to multi-labels for embedding evaluation.

Dataset Card

Item Description
Source POCA supplementary data (mturk/combined.csv + poems/)
Paper Multi-dimensional Affect in Poetry (POCA) Dataset (ACII 2021); DOI 10.1109/ACII52823.2021.9597451
Languages English (en)
Unit Full poem text
Labels Multi-label subset of 20 affects
Size train=228; test=61 (matched poems with text)
Splits Stratified by primary (highest-mean) affect ≈ 80% / 20%, seed=42
Evaluation metrics Multi-label classification on embeddings: macro/micro F1, Average Precision (AP)

Label binarization (from score statistics)

MTurk scores are noisy (annotator std ≈ 2.6 on a 0–10 scale) and absolute thresholds leave many empty / over-dense label sets. We therefore use:

  1. Aggregate mean score per affect across annotators for each poem.
  2. Compute within-poem z-scores; keep affects with (z \ge 1.0).
  3. Always include the top-1 affect (guarantees ≥1 label).

Mean labels/poem ≈ 3.12.

Features

Field Type Description
id string Example id
title string Poem title
author string Poet
poem string Full poem body
labels list[int64] Affect class indices
label_names list[string] Canonical affect names
scores list[float64] Mean MTurk intensities (length 20, taxonomy order)
n_annotators int64 Number of MTurk annotations aggregated

Construction method

  1. Load MTurk combined.csv; group by (title, Author); average the 20 affect columns.
  2. Resolve poem text from poems/ via normalized filename matching.
  3. Binarize with within-poem (z \ge 1.0) + top-1.
  4. Stratified train/test split by primary affect.
