Introduction

This repository contains the implementation code for the experiments in the paper "Abstract Syntax Tree for Programming Language Understanding and Representation: How Far Are We?".

data-process - Contains code for generating AST using JDT, srcML, Antlr and Tree-sitter, and code for preprocessing AST into BFS sequence, SBT, AST Path, Binary Tree and Split AST.

code-clone-detection - Contains code for the code clone detection task using BiLSTM, Transformer, Child-Sum TreeLSTM, N-ary TreeLSTM and AST-Trans.

code-summarization - Contains code for the code summarization task using BiLSTM, Transformer, Child-Sum TreeLSTM, N-ary TreeLSTM and AST-Trans.

code-search - Contains code for the code search task using BiLSTM, Transformer, Child-Sum TreeLSTM, N-ary TreeLSTM and AST-Trans.
