Concept to commit: A pattern designed to trace code changes from user requests to change implementation by analyzing mailing lists and code repositories

The concept to commit pattern is used for tracing code changes from user requests (analyzing the mailing list) to change implementation (analyzing the code repository). The analysis is done via text mining of both emails and commits descriptions in 4 stages. The first stage is identifying a search time window for the mailing list by evaluating a targeted commit time stamp. Once a window is established, the body of the mailing list is reduced to match the search window. The next stage involves basic text mining processing (tokenization, stemming, and document matrix creation). The final step is to perform frequency analysis (word cloud, heat map, or dendrogram).
