| Abstract (ENG): |
Spreadsheets are active documents that are heavily employed in administration, financial forecasting, education, and science because of their intuitive, flexible, and direct approach to computation. But they are also error-prone, poorly documented, often contain actual data in legacy form. Therefore, assistance for
high-impact spreadsheet users is needed. To determine what kind of help could be useful, we analyze user expectations with an “Wizard-of-Oz” experiment. This shows that background knowledge is missing in spreadsheets.
In the SACHS project we approach the missing background knowledge by adding a semantic layer. We illustrate spreadsheets with a semi-formal domain ontology
and equip them with a semantically transparent interface that allows new forms of interaction like “semantic navigation”, “framing”, or “playing with variants”, on
which a survey is given. Moreover, an integration of assessment knowledge into the SACHS approach is presented. We model it based on theory graphs and sketch a
potential SACHS extension with innovative assessment interaction. |
