Complicated documenting work (e.g., research activities) has proceeded by stacking the creation of multiple types of documents and their elaboration while conducting surveys such as Web search, discussions, and taking notes. It is important in long-term complicated documenting work to accumulate the results and circumstances of each work, and utilize them in later work. However, circumstances of the work tend to be lost because the information involved with the tasks becomes enormous in proportion to elapsed time and the data in those tasks are scattered. Moreover, the context of the series of work also becomes complicated through trial and error. Therefore, documenting workers is easy to overlook in important gaze targets. So, it takes time and effort to utilize the results from past work in the latest research. This research was aimed at developing methods of organizing the contexts of elaboration processes. We also aimed at developing a novel mechanism of extracting and visualizing important portions from the contexts according to the latest foci of attention. This paper describes a system of dynamically visualizing the contextual networks and the gaze targets on it along with these methods.
