title: ANEST Narrative–Affect Representations (ANAD v1): Derived Feature Resource for Studying Narrative–Affect Discrepancy

description: ANEST Narrative–Affect Representations (ANAD v1) is a large-scale, fully curated research resource designed to quantify narrative–affect discrepancy using derived, non-identifiable feature representations of human-generated text.

Although registered as a dataset for archival purposes, ANAD v1 functions primarily as a derived feature research resource rather than a raw text corpus.

Developed at the Ryan Research Institute (RRI), Paris, ANAD v1 integrates narrative structure metrics, affective polarity summaries, and a discrepancy index (NADI_abs) to support aggregate-level and population-level analysis of emotional incongruence in narrative expression.

This release contains derived representations only and does not include raw text, usernames, or personal metadata.

 

The resource is intended for use in computational psychology, affective computing, mental health modeling, and Emotional AI research, where reproducible analysis of narrative–emotion relationships is required without exposure to individual-level content.

 

Version note (v1.1)

This update adds additional derived affect summaries computed from sentence-level VADER valence and manuscript-ready statistics for LoC–affect associations.

 

New files include:





anad_mav_rms_only.parquet (N = 351,734; columns: id, LoC, v_mean, v_mean_abs, v_mav, v_rms, v_sd, flip_rate)




loc_affect_corr_table.csv (Pearson and Spearman correlations used in the companion manuscripts)



 

Privacy notice:

This release contains derived feature representations only and does not include raw post text or user metadata.

 

Resource components

 

(1) Narrative–affect feature representations





351,734 anonymized observations represented as narrative and affective feature vectors after cleaning and filtering




Narrative metrics: Length-of-Context (LoC), structural complexity, narrative density




Affective metrics: VADER-derived sentiment polarity (normalized), affect variance




Discrepancy index:

NADI_abs = |LoC − sentiment_norm| (continuous scale, 0–10)



All primary analytic files are provided in efficient Parquet format for high-performance processing.

 

(2) Statistical and diagnostic documentation





Summary statistics (summary_stats_v1.csv)




Correlation matrices across narrative and affective variables (corr_matrix_v1.csv)




Diagnostic feature-level samples illustrating high- and low-NADI regimes (non-textual summaries)




Group-level comparisons for high vs. low NADI_abs regimes




Histogram bin tables for reproducible visualizations



 

(3) Reproducibility and metadata





Dataset schema (dataset_schema_v1.json)




Full preprocessing and scoring pipeline (anest_nadi_pipeline_v1.ipynb)

Data provenance and ethical clarification

Source texts underlying the derived features were drawn from a long-running public discussion forum via archival and official APIs (2012–2023).

All preprocessing, anonymization, and feature extraction were performed at RRI.

 

No verbatim text is included in the primary analytic files, and no attempt is made to identify, reconstruct, or attribute individual-level narratives or authors.

The resource is provided exclusively to support statistical, theoretical, and computational research using aggregate representations.

 

Relation to companion work

In this release, the discrepancy index is provided as a simple absolute-difference measure:

NADI_abs = |LoC − sentiment_norm|

A more advanced, residual-based variant of the Narrative–Affect Discrepancy Index—defined via generalized additive models and used to analyze the geometry of the narrative–affect space—is introduced in the companion article

"The Great Narrative–Affect Gap" (Kim, companion article).

That residual-based NADI can be derived from ANAD v1 using the public pipeline and documentation provided here.

 

ANAD v1 is part of the broader ANEST (Affective Neurocomputational Storytelling) research program at RRI, which investigates emotional reasoning, predictive selfhood, and affective sovereignty in both human and artificial systems.
