After logging to your workspace, the first thing that you have to do is choose a lexicon that will be the source of data for ViCoS during this session. In the right upper corner there is a field called Lexicon. In the roll-out menu of that field you will find all the lexicons that exist in your workspace in LEXUS with the same names as in LEXUS. Remember that your workspace in ViCoS is linked to that of LEXUS, so you cannot work on lexicons that are not in that particular workspace:

Figure 2.4. Choosing the lexicon

Sometimes you have only one lexicon in your workspace in LEXUS, which means that there will be only one lexicon to choose from in ViCoS. Still, whenever you start a new session in ViCoS you have to click the roll-out menu and choose that lexicon. This menu also allows you to switch between lexicons - you just have to open the roll-out menu and choose a different lexicon to start working on a different conceptual space.
