How to replicate

About the Datasets

All of the datasets for 16 different projects are available in the marked_data folder Each dataset has the following 5 columns:

1. issuekey: Issue ID
2. title: Issue Title
3. description: Issue Description
4. storypoint: Assigned Story Point of the Issue
5. split_mark: Represent whether the row was used as training, validation, or testing

issuekey	title	description	storypoint	split_mark

About the Models

Model Naming Convention

All of the models on HuggingFace Model Hub and Google Drive has the same naming convention as described in the following table:

Model ID	Model Specification	Experiment Scenario
#0	BPE GPT2 Tokenizer + Custom Pre-trained GPT-2 (GPT2SP)	Within-Project
#00	BPE GPT2 Tokenizer + Custom Pre-trained GPT-2 (GPT2SP)	Within-Repository
#000	BPE GPT2 Tokenizer + Custom Pre-trained GPT-2 (GPT2SP)	Cross-Repository
#2	Word-levelSP Tokenizer + Custom Pretrained GPT-2	Within-Project
#22	Word-levelSP Tokenizer + Custom Pretrained GPT-2	Within-Repository
#222	Word-levelSP Tokenizer + Custom Pretrained GPT-2	Cross-Repository
#6	WordPieceSP Tokenizer + Custom Pretrained GPT-2	Within-Project
#66	WordPieceSP Tokenizer + Custom Pretrained GPT-2	Within-Repository
#666	WordPieceSP Tokenizer + Custom Pretrained GPT-2	Cross-Repository
#7	SentencePieceSP Tokenizer + Custom Pretrained GPT-2	Within-Project
#77	SentencePieceSP Tokenizer + Custom Pretrained GPT-2	Within-Repository
#777	SentencePieceSP Tokenizer + Custom Pretrained GPT-2	Cross-Repository

How to access the models

• Three different pre-trained tokenizers can be found in the all_tokenizers folder: Word-levelSP Tokenizer, WordPieceSP Tokenizer , and SentencePieceSP Tokenizer
• All of the models included in our experiments can be found on the Model Hub provided by HuggingFace
• For your information, the models can also be downloaded from this Google Drive

About the Model Training Process

• All of the training scripts for different pre-trained tokenizers included in the experiments (RQ3) can be found in tokenizer_training_notebook.ipynb
• The model training scripts can be found in model_training_notebook.ipynb that contains all of the model training process for our experiments (RQ1 + RQ2 + RQ3)

About the GPT2SP Web App

• Access the GPT2SP web app here to interact with our GPT2SP model and navigate the datasets
