The overall structure of CodeEx is illustrated using a Java code script as an example. In the upper part, the overall expansion process involves passing the code through an encoder-decoder structure to obtain a semantic expansion for the term ’play voice.’ Utilizing global attention during this expansion, CodeEx extracts keywords from the code snippet and performs a homonym search to further expand these keywords. Finally, the two expansions are combined to produce the complete code expansion.
