Task Classification with Chronological Action History for PSP Support

This paper proposes a method to support Personal Software Process (PSP) in a development organization by classify the operations on a computer into a purpose of the user. PSP requires the developers to record and analyze their activity during the development process. There are several methods and systems to support the PSP, they records the operations automatically and also records a purpose of the operations (task) which records manually by the developer. Such manual recording by the developers is a barrier to introduction of the PSP system, and the cause of inaccurate record histories. Our proposal method classifies the operations into the task automatically with the chronological operation history. The method hypothesize that the each task consists of successive operation. The method classify the each operation into the task with a machine learning algorithm, Random Forests. An Experiment result shows the proposal method with chronological operation history classify the operation into the tasks more accurately than the method without the chronological operation history.
