Context Elicitation by User Observation in EPOS

Document Actions

This project line of EPOS is managed by Sven Schwarz. The results are published and maintained at . The goal is to estimate a user's context automatically and, hence, without disturbing and distracting him.

When we talk about context we are focusing on contextual information relevant for (personal) knowledge management aspects. This means, we are not sensoring the room temperature or the user's heart beat frequency.

We are mainly observing the user's interactions with his PC. (Personal) Knowledge Management work is focussing on text work. Therefore, we are observing text-oriented actions in particular. For example, writing or replying to emails, or browsing the web, etc.

The user observation is done by

The observed user actions are taken as evidences

Short description of the destination of this part of the EPOS project:

  • Human uses the computer to help him do his work.
  • Usage of computer is done in a nowadays typical way, i.e., a graphical user interface providing access to applications running on the user's machine.
  • Applications, tools, operating system components, etc. allow for interactions with objects on the machine and in the world (documents, e-mails, etc.).
  • Such objects can be created, stored, viewed, edited, etc.
  • We observe the user doing his work in order to get a clue about his intentions and goals.
  • The user's intentions, goals, application usage are part of the context he is in.
  • This context will be used to support the human's work with context-sensitive, pro-active knowledge assistance which will make his work easier. Think of an intelligent assistant helping you with
    • minor working steps
    • remembering you of important appointments
    • showing you related information

Research Topics:

  • Specify a generic Workspace Model
    • objects
    • operations / operators on these objects
  • Instantiate and observe the / all / some applications and operating systems components
    • Web Browser, E-Mail Client: Emmanuel Gasne implemented the user observation plugins for Mozilla Thunderbird and Firebird. More information can be found here
    • Open Office, Text Editor, File Explorer
    • Notes Application, proFiler (multi-criterial document archive and classification)
  • Specify different levels of user activity
  • Mapping observed workspace events to user actions (user intentions, i.e., short-term goals)
    • -> plan recognition
  • Mapping user actions to task concepts (user goals, i.e., mid-term goals)
  • Mapping task concepts to workflow working steps (user is embedded in / assigned to workflows -> long-term goals)
    • -> process / task identification
    • semantic description of workflows / tasks
  • Create a context elicitation framework
