Operation record based work events grouping method for personal information management system

In order to improve the efficiency of any business, it is very important to reuse knowledge by accumulating it in a computer. We propose a method that accumulates and reuses the knowledge of work by automatically extracting it from a user´s operation records during ordinary use on a personal information management (PIM) system. We assume that related work events on the PIM are input and referred to consecutively by the user. Our method of extracting the available knowledge constructs a workflow by grouping all related events and detecting milestones based on the time and order of operating target events. Usually, the reference to events is the user´s view of events on the calendar, without involving any operations, so recording a target event and the time of reference is difficult. In order to record the user´s reference behavior exactly, we introduce a balloon-help-based function for event reference support
