The previous secti<strong>on</strong>s have shown that knowledge work executi<strong>on</strong> can be captured by core executi<strong>on</strong><br />

processes based <strong>on</strong> a vocabulary <str<strong>on</strong>g>of</str<strong>on</strong>g> hierarchically c<strong>on</strong>nected desktop operati<strong>on</strong>s and knowledge<br />

acti<strong>on</strong>s. <strong>Knowledge</strong> acti<strong>on</strong>s are work techniques that require desktop operati<strong>on</strong>s as applicati<strong>on</strong> usage<br />

to execute tasks. The different applicati<strong>on</strong>s and thus <str<strong>on</strong>g>the</str<strong>on</strong>g> different operati<strong>on</strong>s guided by <str<strong>on</strong>g>the</str<strong>on</strong>g> acti<strong>on</strong>s are<br />

c<strong>on</strong>nected by transiti<strong>on</strong>s that occur during task executi<strong>on</strong> in <str<strong>on</strong>g>the</str<strong>on</strong>g> form <str<strong>on</strong>g>of</str<strong>on</strong>g> applicati<strong>on</strong> switches. As <str<strong>on</strong>g>the</str<strong>on</strong>g><br />

acti<strong>on</strong>s and operati<strong>on</strong>s can be applied in different tasks <str<strong>on</strong>g>the</str<strong>on</strong>g>y do not support <str<strong>on</strong>g>the</str<strong>on</strong>g> identificati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> task<br />

instances in work executi<strong>on</strong>. Informati<strong>on</strong> about differences <str<strong>on</strong>g>of</str<strong>on</strong>g> tasks is assumed to manifest in <str<strong>on</strong>g>the</str<strong>on</strong>g><br />

textual c<strong>on</strong>tent that is accessed during task executi<strong>on</strong>. The following secti<strong>on</strong> presents a study that<br />

focuses <strong>on</strong> textual c<strong>on</strong>tent.<br />
