SeeHow: Workflow Extraction from Programming Screencasts through Action-Aware Video Analytics. 45th ACM/IEEE International Conference on Software Engineering (ICSE 2023). The paper proposes a deep learning model that can recognize human-understandable structured user actions from action screencasts, which is useful for UI testing, bug reproduction, and robotic process automation, and has been confirmed to be effective and generalizable through extensive experiments on a large data set of video-action pairs from various applications.

Represent Them All: A Universal Learning Representation of Bug Reports. 45th ACM/IEEE International Conference on Software Engineering (ICSE 2023). The paper discusses how existing automated software maintenance techniques that use deep learning are limited by their need for customized bug report representations, leading to complexity, cost, and compatibility issues, but proposes a pre-trained approach called RepresentThemAll that uses a universal bug report framework with carefully designed learning objectives, and demonstrates superior performance on four downstream tasks.

In ACM Transactions on Software Engineering and Methodology (TOSEM). Accepted. The paper proposes a new approach for code search called deGraphCS, which uses a learnable deep Graph to transfer source code into variable-based flow graphs, providing a more precise modeling of code semantics than existing methods, and achieves state-of-the-art performance in accurately retrieving code snippets from a large-scale dataset of C language code.

The paper discusses how code completion in Integrated Development Environments (IDEs) can be improved using a unified multi-task learning approach that considers both the type and value of tokens, and uses a self-attentional architecture to model long-term dependencies, which results in better performance compared to existing methods.

In ACM Transactions on Software Engineering and Methodology (TOSEM). The paper proposes a new approach called SG-Trans which integrates code structure information into a Transformer-based deep learning model for generating accurate code summaries, and achieves superior performance compared to state-of-the-art approaches on two benchmark datasets.
# Fangcheng Qiu, Zhipeng Gao, Xin Xia, David Lo, John Grundy, Xinyu Wang. Deep Just-In-Time Defect Localization. IEEE Transactions on Software Engineering (TSE). DEEPDL is a just-in-time (JIT) defect localization approach that uses a deep learning-based neural language model to locate defect code lines within a defect introducing change, assigning a suspiciousness score to each code line and sorting them in descending order, to assist developers in efficiently checking buggy lines at an early stage and reduce the risk of introducing bugs in time, outperforming state-of-the-art techniques by a substantial margin in experiments on 14 open source Java projects.
