CMRL-paper/CMRL-dataset

Overview

This repository contains a dataset designed for binary code similarity detection, focusing on the semantic alignment between assembly instructions and programming language code snippets. The dataset is created to facilitate the training and evaluation of models in tasks related to binary function similarity detection, code reuse analysis, and software security.

Dataset Description

The dataset consists of pairs of assembly instructions and corresponding programming language code snippets extracted from various open-source projects. It is curated to ensure high-quality, semantically aligned pairs that can be used for supervised and unsupervised learning tasks.

Usage

Requirements

• Python 3

Generating Dataset

Use genDataset.py to process the .txt files in OriAsmFile.zip.

Loading the Dataset

• The dataset data structure is defined as:{'Function':"",'Code':[{'PLcode':"",'ASMcode':""}]}
