# EmoArt: Emotion-Aware Artistic Datasets

EmoArt is an emotion-centered designation in recent computational art, affective computing, and generative modeling literature for datasets and benchmarks that connect artistic imagery, formal visual properties, and affective supervision. The name is used most prominently in two ways: as a multidimensional painting dataset of **132,664 artworks** with structured annotations for content, formal attributes, valence–arousal, emotion categories, and therapeutic potential [2506.03652], and as a **13,633**-image WikiArt-based artistic extension used to demonstrate the scalability of CoEmoGen for emotional image content generation [2508.03535]. A later line of work extends the former with a **1,400**-artwork human-salience benchmark for attribute-grounded selective reasoning about which formal cues are emotionally operative in a given artwork [2605.15755].

## 1. Terminology and referents

In current usage, **EmoArt** is not a single method. It denotes dataset-level resources that occupy different positions in the pipeline of emotion-aware artistic AI: corpus construction, supervised generation, and explanation-grounded reasoning. This naming overlap is consequential because the two principal EmoArt resources differ substantially in scale, annotation granularity, and intended task formulation [2506.03652].

| EmoArt usage | Scale | Primary role |
|---|---:|---|
| Multidimensional EmoArt | 132,664 artworks | Emotion-aware artistic generation and benchmarking |
| CoEmoGen EmoArt | 13,633 art images | Scalable art-domain extension for EICG |
| EmoArt salience extension | 1,400 artworks | Attribute-grounded selective reasoning |

The larger multidimensional resource is explicitly framed as a response to the fact that many earlier emotion datasets are **photo-centric**, provide only **coarse emotion labels**, or lack the **fine-grained visual attribute annotations** needed for emotion-grounded artistic synthesis [2506.03652]. The CoEmoGen version instead serves as a proof-of-concept for scalable art-domain expansion using **MLLM-generated sentence-level captions** rather than manually curated word-level attributes [2508.03535]. The salience extension recasts EmoArt as a benchmark for explanation quality, asking not merely which attributes are visible, but which ones actually support the affective judgment for a specific artwork [2605.15755].

## 2. Multidimensional dataset design

The multidimensional EmoArt dataset contains **132,664 artworks** across **56 painting styles**, drawn from open or public collections including **WikiArt**, **The Met**, **Europeana**, and other museum or open-access sources. The authors report an initial collection of **over 200,000 artworks** from more than **150 styles**, followed by four filtering stages: **art form filtering** to keep only paintings, **content safety filtering**, **image quality filtering** to remove images below **300×300** or with artifacts, and **category balance filtering** to remove styles with fewer than **400 samples** [2506.03652].

Its central contribution is a five-part annotation schema intended to bind depicted content, formal visual structure, and affective interpretation into a unified supervisory signal. Each image includes:

- an **objective scene/content description**;
- **five visual attributes**: **Brushwork**, **Composition**, **Color**, **Line**, and **Light**;
- **binary arousal–valence labels** based on Russell’s circumplex model;
- **12 representative emotion categories**;
- a label for **potential art-therapy effects**.

The arousal–valence layer is defined as
$$
\text{Arousal} \in \{\text{High}, \text{Low}\}, \qquad \text{Valence} \in \{\text{Positive}, \text{Negative}\}.
$$
The twelve emotion categories are distributed across the arousal–valence plane: **aroused**, **excited**, and **happy** for positive high arousal; **alarmed**, **annoyed**, and **frustrated** for negative high arousal; **sad**, **bored**, and **tired** for negative low arousal; and **content**, **calm**, and **glad** for positive low arousal [2506.03652].

The descriptions are intended to exceed ordinary captioning in affective and formal specificity. The paper reports an average of **35.6 words per description**, compared with **15.8** for ArtEmis and **10.5** for COCO captions. Annotation was produced through **GPT-4o-assisted generation** with **human verification** and **multi-round checking**, and validated on **5,600 images** across the 56 styles by **10 trained annotators**. Reported agreement with human labels is **98.01%** for descriptions, **98.56%** for visual attributes, and **91.47%** for emotion; the paper also reports **Gwet’s AC1** and **McNemar’s test** [2506.03652].

The dataset is affectively imbalanced in a way that is itself analytically useful. The reported distribution is **87.93% Positive valence**, **76.41% Low arousal**, with **Calm** at **55.95%**, **Excited** at **15.50%**, and **Contentment** at **15.35%**. The paper further notes style-dependent tendencies: **Realism** and **Romanticism** tend to be calm and peaceful; **Expressionism** and **Surrealism** show more high-arousal and negative affect; **Chinese painting**, **Ukiyo-e**, and **Gongbi** are strongly associated with low-arousal positive emotion; and **Social Realism** shows higher negative valence and alarm [2506.03652].

## 3. Scalable art-domain extension for CoEmoGen

Within CoEmoGen, EmoArt is presented as **the first large-scale emotional art image dataset** and functions as a scalable artistic extension of an existing emotional image content generation pipeline. It contains **13,633 emotionally representative artistic images** collected from **WikiArt**, spanning **129 artists**, **11 genres**, and **27 styles** [2508.03535].

Its construction pipeline is deliberately standardized. The authors collect about **100,000** WikiArt images, predict an emotional category for each image using a classifier trained on **EmoSet**, retain only those with **emotion confidence above 0.75**, and then generate **one-sentence captions** with the same MLLM-based captioning procedure used elsewhere in CoEmoGen. To reduce hallucination, they compute **CLIP similarity** for each image–caption pair and discard the **bottom 20%** of samples in each emotion category [2508.03535].

A notable design decision is emotion-set reduction. The Mikels model originally supplies eight categories—**amusement**, **awe**, **contentment**, **excitement**, **anger**, **disgust**, **fear**, and **sadness**—but the paper states that **excitement** and **disgust** are rare in artistic expressions and account for **less than 1%** in this context. EmoArt therefore focuses on six emotions: **amusement**, **awe**, **contentment**, **anger**, **fear**, and **sadness** [2508.03535].

The captioning protocol makes the emotion label explicit prior knowledge. The MLLM is prompted to produce a one-sentence description emphasizing emotion-related visual details such as **brightness**, **colorfulness**, **scene type**, **object classes**, **facial expressions**, and **human actions**. This makes EmoArt, in the CoEmoGen sense, not merely a curated image set but an instantiated example of a **sentence-level semantic supervision** pipeline meant to replace weaker word-level attribute labels [2508.03535].

## 4. Role in emotion-aware artistic generation

The multidimensional EmoArt resource is explicitly designed to support generation as well as understanding. Its prompt template is formulated as
$$
\text{Style} + \text{Arousal} + \text{Valence} + \text{Description},
$$
thereby making emotion a primary conditioning signal rather than an auxiliary tag. For evaluation, the paper uses **FID**, **SSIM**, **PSNR**, **LPIPS**, and a proposed **Attributes Alignment** metric. The latter is computed by fine-tuning **MiniCPM-V-2.6** on EmoArt and measuring similarity to the target text in **CLIP embedding space**. Benchmarking includes **FLUX.1-dev**, **FLUX.1-schnell**, **SDXL**, **Stable Diffusion 3.5**, **PixArt-sigma**, **Playground**, and **OpenJourney**; a **LoRA** fine-tuned **FLUX.1-dev** model trained on **50 paintings per artistic category** and conditioned on **Description, Arousal, and Valence** performs best on most subjective and artistic measures, including **brushstroke**, **color**, **composition**, **line quality**, and **overall quality** [2506.03652].

The CoEmoGen version of EmoArt serves a different generative purpose. There, EmoArt is not a separate model but a demonstration that sentence-level caption supervision can be transferred to a new artistic domain. The framework combines **MLLM-generated emotion-triggering captions** with **HiLoRA**, a parameter-efficient module based on the claim that emotions of the same polarity share low-level attributes but differ in high-level semantics. HiLoRA contains **2 polarity-shared LoRAs** and **8 emotion-specific LoRAs**, with an update rule
$$
W' = W + \Delta W = W + A \cdot B,
$$
and, for a positive-polarity example such as amusement,
$$
W' = W + \Delta W_1^p + \Delta W_2^e = W + A_1^p B_1^p + A_2^e B_2^e.
$$
In this interpretation, the polarity-shared component captures common low-level cues such as **brightness** and **colorfulness**, while the emotion-specific component captures finer semantics [2508.03535].

The overall implication is that EmoArt-based generation research has split into two complementary strategies. One emphasizes **rich multidimensional supervision** and benchmarking across mainstream diffusion backbones; the other emphasizes **scalable caption-centric expansion** into new artistic domains. This suggests that “EmoArt” has become a focal term for moving emotional image generation beyond coarse class labels and toward art-specific conditioning structures.

## 5. Salience-grounded reasoning and explanation

The 2026 extension of EmoArt reframes the resource as a benchmark for **artwork emotion understanding** under **Attribute-Grounded Selective Reasoning (AGSR)**. The key claim is that MLLMs often suffer from **attribute flooding**: they enumerate many visible formal properties without isolating which ones actually support the emotion judgment. To make this measurable, the authors add a **1,400-artwork** human-salience extension annotated by **15 annotators** with formal art-training backgrounds [2605.15755].

The formal attribute vocabulary is
$$
\mathcal{A}=\{\mathrm{color},\mathrm{composition},\mathrm{line},\mathrm{light},\mathrm{brushstroke}\}.
$$
For each artwork, annotators assign binary salience decisions over these five attributes. The central distinction is between attributes that are merely present and attributes that are **emotionally operative**. The modeling desideratum is sparse evidence selection:
$$
\|\mathbf{s}(x)\|_0 \ll |\mathcal{A}|.
$$

The proposed method, **FAB-G** (**Formal-Attribute Bottleneck-Guided reasoning**), operationalizes AGSR in two stages. First, five attribute-specific agents predict salience decisions,
$$
s_a = g_a(x;\theta_a) \in \{0,1\},
$$
yielding the retained set
$$
\mathcal{S}(x)=\{a \in \mathcal{A} \mid s_a=1\}.
$$
Second, a final analysis agent generates affective predictions and explanations conditioned on the selected subset rather than the full attribute inventory [2605.15755].

On **Qwen3-VL**, the reported results are: **Base Model** at **29.33%** emotion, **56.67%** arousal, and **80.00%** valence; **CoT-SFT** at **48.67%**, **78.00%**, and **88.00%**; and **FAB-G** at **50.00%**, **82.00%**, and **90.00%**. Evidence alignment is measured by **Dice** and **Tversky**; the best FAB-G scores on EmoArt are **0.8742 / 0.8808** sample-wise mean and **0.8450 / 0.8454** attribute-wise mean, with \(\alpha=0.8\) and \(\beta=0.2\) in the Tversky metric to penalize false positives more heavily. Explanations also become markedly shorter: for Qwen3-VL, **FAB-G** produces **57.56 tokens**, compared with **145.71** for **CoT** and **140.15** for **One-shot** prompting. Cross-dataset evaluation on **Abstract**, **ArtEmis**, and **WikiArt** further suggests transfer beyond the source distribution, while exposing that **Line**, **Light**, and **Brushstroke** remain harder than **Color** and **Composition** [2605.15755].

## 6. Methodological issues, limitations, and significance

Several methodological constraints recur across the EmoArt literature. First, the multidimensional EmoArt dataset is limited to **paintings**, not all art media, and removes styles with fewer than **400 samples**, improving balance at the cost of reducing long-tail coverage [2506.03652]. Second, the CoEmoGen EmoArt subset depends on **classifier-based emotion filtering**, **MLLM caption quality**, and **CLIP-based filtering**, so its quality is partly inherited from upstream components [2508.03535]. Third, even the salience extension models only **five formal attributes**, while emotional interpretation may also depend on **iconography**, **cultural background**, and **viewer experience**; the salience subset is also modest relative to the full corpus, and **Light** is reported as especially difficult to transfer reliably across datasets [2605.15755].

A common misconception is to treat art emotion as a single-label property. Earlier work already showed that affective interpretation in art is substantially subjective: ArtEmis reports **439,121** emotion attributions and explanations on **81,446 artworks**, and **61%** of artworks receive at least one positive and one negative emotion across annotators [2101.07396]. EmoArt’s design choices can be read as responses to that fact. The multidimensional version introduces layered supervision rather than a single target label; the CoEmoGen version reduces the label set where artistic frequency is low; and the salience extension separates visible attributes from emotionally admissible evidence.

Within the broader research trajectory, EmoArt sits between affective language resources and emotion-conditioned generation frameworks. **ArtEmis** contributes grounded human explanations for why artworks evoke emotions, but not the five-attribute structured supervision used in EmoArt [2101.07396]. **EmoGen** formulates **Emotional Image Content Generation (EICG)** and introduces evaluation concepts such as **Emo-A**, **Sem-C**, and **Sem-D** for emotion-faithful generation [2401.04608]. EmoArt extends this agenda into art-specific corpora where content, style, formal properties, and affective labels are jointly organized.

Taken together, the EmoArt literature defines a research program rather than a single artifact: building art-domain resources in which **what is depicted**, **how it is formally rendered**, and **what it is felt to express** become computationally linked. That program now spans dataset curation, multimodal caption induction, diffusion benchmarking, and bottlenecked reasoning about emotionally operative evidence.
