NEDO Turkish SFT Mixtures

This dataset repository contains Turkish supervised fine-tuning datasets prepared for the NEDO Turkish SLM project.

The datasets were built to fine-tune NEDOQwen-style Turkish decoder-only language models after base pretraining on the NEDO Turkish 65K tokenized web corpus.

Main related pretraining dataset:

Ethosoft/nedo-turkish-65k-tokenized-60b

Summary

This repository contains two main SFT mixtures:

File	Examples	Recommended?	Description
data/tr_sft_clean_20k.jsonl	20,000	Yes	Cleaner Turkish instruction subset used for better SFT behavior
data/tr_sft_hf_mix.jsonl	104,078	Experimental	Larger but noisier Turkish instruction mixture

A small smoke-test dataset was used internally during development but is not the main release.

Files

data/tr_sft_clean_20k.jsonl
data/tr_sft_hf_mix.jsonl
metadata/sft_dataset_info.json
scripts/46_build_tr_sft_mix.py
scripts/50_build_clean_sft.py

Recommended starting point

For most users, start with:

data/tr_sft_clean_20k.jsonl

This file is smaller, cleaner, and was more useful in early NEDO SFT experiments.

The larger file:

data/tr_sft_hf_mix.jsonl

is broader but noisier. It may be useful for experimentation, filtering, or continued dataset curation, but should not be treated as a high-quality benchmark.

Dataset variants

tr_sft_clean_20k.jsonl

• Examples: 20,000
• Format: JSONL
• Fields: instruction, input, output, source
• Status: recommended clean subset

Upstream sources used during construction:

• SoAp9035/turkish_instructions
• Dbmaxwell/turkish-finance-instruction-dataset

This dataset was built after filtering out noisier translation-style data from the broader SFT mixture. In internal NEDO experiments, it produced better basic QA and instruction-format behavior than the larger HF-mix dataset.

tr_sft_hf_mix.jsonl

• Examples: 104,078
• Format: JSONL
• Fields: instruction, input, output, source
• Status: broader experimental mixture

Upstream sources used during construction:

• NovusResearch/turkish_instructions
• SoAp9035/turkish_instructions
• Dbmaxwell/turkish-finance-instruction-dataset

This mixture is more diverse, but internal experiments showed that it can produce weaker structured-prompt behavior without further cleaning.

Format

Each line is a JSON object:

{
  "instruction": "...",
  "input": "",
  "output": "...",
  "source": "..."
}

The expected fields are:

• instruction: user instruction or task
• input: optional extra context; can be empty
• output: target assistant response
• source: upstream dataset/source identifier

Prompt format used in NEDO SFT

When input is empty, examples were formatted as:

Kullanıcı talimatı:
{instruction}

Asistan cevabı:
{output}

When input is non-empty, examples were formatted as:

Kullanıcı talimatı:
{instruction}

Ek bilgi:
{input}

Asistan cevabı:
{output}

During training, the prompt portion was masked with -100 labels and loss was computed only on assistant answer tokens.

Example loading

import json

path = "data/tr_sft_clean_20k.jsonl"

with open(path, "r", encoding="utf-8") as f:
    for line in f:
        example = json.loads(line)
        print(example["instruction"])
        print(example["output"])
        break

Relationship to NEDOQwen

These SFT mixtures were prepared for NEDOQwen 0.8B Turkish SLM experiments.

Related resources:

• Pretraining dataset: Ethosoft/nedo-turkish-65k-tokenized-60b
• Base model: planned NEDOQwen 0.8B base release
• Clean SFT model: planned NEDOQwen 0.8B clean-SFT release

Internal experiment notes

In the NEDO project handoff:

• HF-mix SFT completed technically but produced weak structured-prompt behavior.
• Clean 20K SFT performed better than HF-mix.
• Clean SFT could answer simple factual questions such as “Fransa'nın başkenti nedir?”
• Domain-specific SFT is still needed for strong SLM/LLM/agent-domain behavior.

Data quality notes

This repository should be treated as an SFT research artifact.

Known characteristics:

• Turkish instruction-following format
• mixed task types: rewriting, QA, explanation, classification, summarization, formatting, finance-oriented instructions
• some examples may contain translation artifacts
• some examples may contain factual errors or awkward wording
• broader HF-mix file is noisier than the clean 20K subset

License and provenance

This repository is a mixture/derivative of upstream Turkish instruction datasets.

Known upstream sources include:

• NovusResearch/turkish_instructions
• SoAp9035/turkish_instructions
• Dbmaxwell/turkish-finance-instruction-dataset

Downstream users are responsible for checking and complying with upstream dataset licenses and terms, especially for commercial redistribution or production use.

Intended use

This dataset is intended for:

• Turkish supervised fine-tuning
• small language model alignment experiments
• instruction-following research
• Turkish SLM evaluation and ablation studies
• reproducibility of the NEDO Turkish SLM SFT pipeline

Out-of-scope use

This dataset is not intended for:

• use as a factual benchmark
• high-stakes deployment without filtering and evaluation
• commercial redistribution without checking upstream licenses
• treating the broader HF-mix file as fully cleaned data
