| # Dataset Card for Russian Toxicity Detection Dataset |
|
|
| ## Dataset Details |
|
|
| ### Dataset Description |
|
|
| This dataset is designed for **binary classification of toxic and non-toxic Russian texts**. It was created as part of an educational project to build a real-time quality control system for customer support messages. The goal is to automatically distinguish messages containing rudeness, sarcasm, or aggression (toxic) from neutral, polite, or informative messages (non-toxic). |
|
|
| - **Curated by:** RooLeX |
| - **Language(s):** Russian (ru) |
| - **License:** MIT License |
|
|
| ### Dataset Sources |
|
|
| - **Repository:** https://huggingface.co/datasets/RooLeX/Homework2-llm |
|
|
| ## Uses |
|
|
| ### Direct Use |
|
|
| This dataset is intended for training and evaluating binary text classification models that detect toxicity in Russian-language texts. It can be used in content moderation systems, customer support quality control, social media monitoring, and similar applications. |
|
|
| ### Out-of-Scope Use |
|
|
| - The dataset is not suitable for detecting toxicity in languages other than Russian. |
| - It should not be used to make automated decisions about individuals without human oversight. |
| - The dataset is balanced (equal number of toxic and non-toxic examples), which may not reflect real-world class distributions. Models trained on it may require threshold tuning for production use. |
|
|
| ## Dataset Structure |
|
|
| ### Data Fields |
|
|
| - **`text`** (`string`): The text content of the message. |
| - **`label`** (`int`): Binary label indicating toxicity (0 = non-toxic, 1 = toxic). |
|
|
| ### Data Splits |
|
|
| The dataset is split into three subsets: |
|
|
| | Split | Number of Examples | |
| |-------------|-------------------| |
| | Train | 59,451 | |
| | Validation | 7,431 | |
| | Test | 7,432 | |
|
|
| All splits are balanced (approximately equal number of toxic and non-toxic samples). |
|
|
| ## Dataset Creation |
|
|
| ### Curation Rationale |
|
|
| The dataset was created to address the problem of automatically detecting toxic messages in customer support communications. Toxic messages can cause significant reputational damage, and the goal is to build a fast, accurate model that can flag or block such messages before they are sent to clients. |
|
|
| ### Source Data |
|
|
| **Toxic class (label = 1)** was collected from publicly available datasets containing toxic Russian comments: |
| - [AlexSham/Toxic_Russian_Comments](https://huggingface.co/datasets/AlexSham/Toxic_Russian_Comments) — comments from the social network ok.ru |
| - [NiGuLa/Russian_Inappropriate_Messages](https://huggingface.co/datasets/NiGuLa/Russian_Inappropriate_Messages) — inappropriate/rude messages |
| - [textdetox/multilingual_toxicity_dataset](https://huggingface.co/datasets/textdetox/multilingual_toxicity_dataset) — multilingual toxicity data (Russian subset) |
|
|
| **Non-toxic class (label = 0)** was sourced from various Russian-language datasets that are unlikely to contain toxic content: |
| - [SetFit/amazon_massive_intent_ru-RU](https://huggingface.co/datasets/SetFit/amazon_massive_intent_ru-RU) — voice assistant commands |
| - [DeepPavlov/mtop_intent_ru](https://huggingface.co/datasets/DeepPavlov/mtop_intent_ru) — user queries and intents |
| - [MTS-AI-SearchSkill/MTSBerquad](https://huggingface.co/datasets/MTS-AI-SearchSkill/MTSBerquad) — question-answer pairs (QA) |
| - [mteb/ru_nlu_intent](https://huggingface.co/datasets/mteb/ru_nlu_intent) — intent classification texts |
|
|
| #### Data Collection and Processing |
|
|
| 1. All source datasets were loaded using the Hugging Face `datasets` library. |
| 2. For toxic sources, only examples labeled as toxic (or inappropriate) were selected. |
| 3. For non-toxic sources, all examples were taken (with label 0). |
| 4. The combined data was cleaned: |
| - Empty strings and NaN values were removed. |
| - Exact duplicate texts were dropped. |
| - Texts with less than 3 words or more than 500 words were filtered out. |
| 5. Classes were balanced using undersampling of the larger class. |
| 6. The balanced dataset was split into train/validation/test sets in 80/10/10 proportion with stratification to preserve class balance. |
|
|
| ### Annotations |
|
|
| The dataset contains no additional annotations beyond the original labels from the source datasets. All labels are binary (toxic/non-toxic). |
|
|
| #### Personal and Sensitive Information |
|
|
| The dataset consists of text snippets from public sources and does not contain personally identifiable information (PII) such as names, addresses, phone numbers, etc. However, some toxic comments may contain offensive language. |
|
|
| ## Bias, Risks, and Limitations |
|
|
| ### Known Biases |
|
|
| - **Domain bias:** Toxic examples are predominantly from social media (ok.ru), while non-toxic examples come from voice assistants, QA systems, and intent data. This may cause the model to perform differently on texts from other domains (e.g., news, forums, email). |
| - **Cultural bias:** The data reflects the cultural and linguistic nuances of Russian-language internet communication, which may not generalize to other languages or regions. |
| - **Labeling bias:** The source datasets use different definitions of toxicity/inappropriateness, which may introduce inconsistencies. |
| - **Balance bias:** The dataset is artificially balanced, which does not reflect real-world toxicity prevalence. |
|
|
| ### Risks |
|
|
| - The model may produce false positives (flagging harmless messages as toxic) or false negatives (missing genuine toxicity), which can have business consequences. |
| - The model may be sensitive to sarcasm, irony, or context, which are hard to capture in short texts. |
|
|
| ### Recommendations |
|
|
| - Users should evaluate the model on domain-specific data before deployment. |
| - A human-in-the-loop review process is recommended for production use. |
| - The classification threshold should be tuned based on business priorities (e.g., lower threshold for stricter moderation). |
