Analysis of Program Representations Based on Abstract Syntax Trees and Higher-Order Markov Chains for Source Code Classification Task

Code for the program classification algorithms described in the paper "Analysis of Program Representations Based on Abstract Syntax Trees and Higher-Order Markov Chains for Source Code Classification Task" [1].

Getting Started

1. Install Docker CE and GNU make.
2. Clone the repository, then clone the submodules using git submodule update --init --recursive
3. Download the dataset [2] from Zenodo and extract the task-*.csv files into src/data.
4. Classification targets can contain digits, so navigate to external/code2vec/common.py and apply the patch:

     @staticmethod
     def legal_method_names_checker(special_words, name):
-        return name != special_words.OOV and re.match(r'^[a-zA-Z|]+$', name)
+        return name != special_words.OOV

5. Run make notebook from repository root, run the notebooks.
