PhD Research

Most knowledge workers have already faced the problem of their personal information sphere (i.e. files, mails, bookmarks, folder hierarchies, etc.) becoming cluttered with meanwhile irrelevant information from being used in many different contexts without time for rehashing or tidying up. Since 2005, Semantic Desktop research has focused on better supporting personal information management and knowledge work activities. For instance, by allowing to easily interconnect resources on the user's computer they are more aligned with the user's mental model. Nevertheless, there is still a high potential for increasing the automation of such support systems.
In my PhD project called Self-organizing Context Spaces (or cSpaces for short), I intend to combine Semantic Desktop technology with Explicated User Context and measures of Managed Forgetting (a variant of Intentional Forgetting) to investigate and provide new levels of user support inspired by human forgetting. By the latter, we understand an escalating set of measures overcoming the binary keep-or-delete paradigm: They range from temporal hiding, to data condensation, to adaptive synchronization, archiving and deletion. The ultimate goal is to develop a self-(re)organizing information system that context-sensitively supports knowledge workers, e.g. by allowing to better focus on the current task or making the large number of user contexts emerging and evolving over time (as well as their content) easier to handle. My work thus also comprises several topics of related areas such as information extraction & retrieval, HCI & usability, data mining & machine learning.
