Resources available:

1. Data set (user story) labeled [1], used for training and test ing the inference model. https://github.com/morakotch/datasets/tree/master/storypoint/IEEE%20TSE2018/dataset

   • Correspond to a set of .CSV files for each of the projects used.

2. Pre-trained embeddings (generic).

   • Available in the folder "pretrain_model"
     • word2vec_base
     • BERT_base

3. Unlabeled data set (user story) used in the fine-tuning process of pre-trained embeddings. https://github.com/morakotch/datasets/tree/master/storypoint/IEEE%20TSE2018/pretrain%20data

4. The pre-processing of the data used to perform the fine-tuning process with BERT, as well as fine-tuning, used the methods provided by the BERT model in its official repository at https://github.com/google-research/bert

   • For data pre-processing: create_pretraining_data.py
     • Standard parameters were used, changing only the following:: -input_file= (inform file .txt containing all the textual requirements provided in item 2) -output_file=./filename.tfrecord -vocab_file= (inform file .txt corresponding to the vocabulary of the pre-trained model used, ex./uncased_L-12/vocab.txt)

5. Pre-trained embeddings (fine-tuned) models for the specific domain of software engineering (SE):

   • word2vec_SE
   • BERT_SE

6. The "SE3M_model.ipynb" file contains a deep learning of architecture used as an inference model for estimating software effort by analogy. Is a Google Colab notebook, simply replacing the paths of the files used.
