  With the rapid development of the large model domain, research related to
fine-tuning has concurrently seen significant advancement, given that
fine-tuning is a constituent part of the training process for large-scale
models. Data engineering plays a fundamental role in the training process of
models, which includes data infrastructure, data processing, etc. Data during
fine-tuning likewise forms the base for large models. In order to embrace the
power and explore new possibilities of fine-tuning datasets, this paper reviews
current public fine-tuning datasets from the perspective of data construction.
An overview of public fine-tuning datasets from two sides: evolution and
taxonomy, is provided in this review, aiming to chart the development
trajectory. Construction techniques and methods for public fine-tuning datasets
of Large Language Models (LLMs), including data generation and data
augmentation among others, are detailed. This elaboration follows the
aforementioned taxonomy, specifically across demonstration, comparison, and
generalist categories. Additionally, a category tree of data generation
techniques has been abstracted in our review to assist researchers in gaining a
deeper understanding of fine-tuning datasets from the construction dimension.
Our review also summarizes the construction features in different data
preparation phases of current practices in this field, aiming to provide a
comprehensive overview and inform future research. Fine-tuning dataset
practices, encompassing various data modalities, are also discussed from a
construction perspective in our review. Towards the end of the article, we
offer insights and considerations regarding the future construction and
developments of fine-tuning datasets.
