Dataset Summary
The KidLM corpus consists of high-quality, child-appropriate content specifically written for children and occasionally by them. This content has been meticulously reviewed and validated by website editors or moderators to ensure suitability and to eliminate any inappropriate content or sensationalism. Our user-centric data collection pipeline with quality filtering is comprehensive, diverse, and carefully tailored for developing language models aimed at young audiences.

Data Instances
One example from our KidLM (corpus) is given below in JSON format.
{
"_id": 6,
"text": "Dink, Josh, and Ruth Rose are on their fun and exciting mystery! Dink has Josh and Ruth Rose to help him with his mystery. Josh likes to eat. Ruth Rose dresses all in one color including her headband. The fifth envelope has something fishy with it. It’s empty but it has something behind the stamps. Read to find out what happens. I think Dink, Josh, and Ruth Rose are curious, excited, happy, and sometimes playful. They are best friends and they want to help each other whatever comes their way. I like this book because Ron Roy has a series called A to Z Mysteries. The series always has a new crime to solve. This book connects to my life because I love solving mysteries. And I have mysteries to solve at my house, a lot of them. Ron Roy is a great writer. I bet he knows a lot about mysteries because his books are very suspenseful. Once you get into the story the crime unfolds but you don’t know who did it until the very end. My favorite part was when they get to drag the criminals off to jail. I can’t tell you who it is because that is telling too much.I would recommend this book for ages 5-18 because they might like mysteries too. And they might want to learn more about solving a crime."

User-Centric Data Collection Pipeline
Our user-centric approach includes gathering text written specifically for or by children. This data is vetted for appropriateness and adjusted to avoid inappropriate material. We focus on both the demographics of content creators and the intended audience, ensuring suitability for young users.
Content Sources: Includes text specifically written for and occasionally by children.
Thorough Review: All content is reviewed and validated by website editors or moderators.
Ensuring Suitability: Emphasis on appropriateness, avoiding sensationalism or inappropriate material.
Two Key Aspects:
- "Who?": Demographics and intentions of content creators.
- "Whom?": Intended audience, ensuring the content is suitable for children.

Data Diversity & Quantity
Data Diversity:
Corpus includes a variety of genres: science, sports, history, animals, geography, technology, current events, book reviews, and more.
Data collected from 21 sources across different regions: USA (4), India (4), Canada (3), Australia (1), UK (1), New Zealand (1), and other global sources (7).
Data Quantity:
- KidLM corpus comprises 286,000+ documents, 2.91 million sentences, and 50.43 million words resulting in 67.97 million tokens.
Data Verification and Filtering
Data Verification
- We manually reviewed the data sources.
- Focused on the "about" sections of identified websites.
- Ensured the quality and relevance of each source for inclusion.
Filtering
Quality Filtering
- Extracted articles tagged specifically for children.
- Identified content labeled as “kidspost.”
- Excluded articles marked as potentially inappropriate (e.g., tagged with red).
- Selected data relevant to specific grade levels (K-1, 2-3, 4-5, and 6).
Additional Filtering
Language Filtering:
- Retained only English-language texts.
- Filtered out code-switched and code-mixed texts.
- Used spacy-langdetect toolkit for language detection.
- Kept sentences with a confidence score of ≥ 0.9 to filter out code-mixed texts.
Personal Identifying Information (PII)
- Data Anonymization: Avoided collecting author names to ensure privacy.
- Preprocessing: Removed personal contact details (e.g., emails, phone numbers, Twitter handles) using regular expressions from the texts.
Considerations for Using the Data
Social Impact of Dataset
The KidLM corpus has the potential to positively impact children’s digital experiences by providing a foundation for developing language models tailored specifically for young audiences. Given that children constitute one in three internet users globally, with those aged 8-12 spending over five hours daily on screens, there is a pressing need for safe, educational, and child-appropriate online content. The KidLM dataset, meticulously curated with high-quality content written for and occasionally by children, addresses this need by ensuring the content is suitable and free from inappropriate or sensational material. For more details, please refer to our EMNLP 2024 paper.
Discussion of Ethics
We took ethical consideration into account when scraping data from the sources. The data we have collected is intended exclusively for non-commercial research purposes. We conducted our web scraping activities at a reasonable rate, with no intention of causing a Distributed Denial of Service (DDoS) attack.
Discussion of Biases
We made significant efforts to minimize offensive content in the pre-training data by deliberately crawling sites where such content is minimal. However, we cannot provide an absolute guarantee that no such content is present. We strongly recommend exercising caution when directly using the KidLM (corpus).
Protection of Privacy
We deliberately chose not to collect specific information, such as author names (whether they are children or reporters) and the publication dates of articles. Additionally, we preprocess the data to remove any personal contact details, including email addresses, phone numbers, and Twitter handles, by applying simple regular expressions to the pre-training corpus. As a result, our dataset minimizes the presence of Personal Identifying Information (PII). This decision highlights our commitment to prioritizing user privacy.

abstract = "Recent studies highlight the potential of large language models in creating educational tools for children, yet significant challenges remain in maintaining key child-specific properties such as linguistic nuances, cognitive needs, and safety standards. In this paper, we explore foundational steps toward the development of child-specific language models, emphasizing the necessity of high-quality pre-training data. We introduce a novel user-centric data collection pipeline that involves gathering and validating a corpus specifically written for and sometimes by children. Additionally, we propose a new training objective, Stratified Masking, which dynamically adjusts masking probabilities based on our domain-specific child language data, enabling models to prioritize vocabulary and concepts more suitable for children. Experimental evaluations demonstrate that our model excels in understanding lower grade-level text, maintains safety by avoiding stereotypes, and captures children{'}s unique preferences. Furthermore, we provide actionable insights for future research and development in child-specific language modeling.",
