The inputs naturally form a heterogeneous graph while the output SQL can be transduced into an abstract syntax tree (AST). Traditional encoder-decoder models ignore higher-order semantics in ...

We not only make the encoder structure-aware by leveraging the source code's syntax tree and data flow graph, but we also support the decoder in preserving the syntax and data flow of the target code ...

This is the repository containing source code for the TAPMI 2023 journal article A Heterogeneous Graph to Abstract Syntax Tree Framework for Text-to-SQL, HG2AST hereafter. If you find it useful, ...
