The GraphViewer is used to browse through the whole corpus (corpus exploration) or to browse through the matching corpus graphs (match visualization). The corpus exploration mode is activated by pressing the Explore corpus button or selecting the Explore item in the Corpus menu. The match visualization is automatically activated after query processing. When opened, the GraphViewer will display the first corpus graph or the first matching corpus graph, respectively.
Please note: You can easily switch between the TIGERSearch main window and the GraphViewer
window using the shortcut buttons in the lower left corner of both windows. If you press
a shortcut button, the corresponding window will be moved in front of all other windows on your desktop.
The tokens of the currently displayed corpus graph is presented at the bottom of the window. You can navigate through the matching corpus graphs by using the navigation panel at the bottom of the GraphViewer. You can either view them one by one in the order they have been found using the Previous and Next buttons, or browse through the corpus graphs using the slider above these buttons.

You can move right to the last graph by pressing the Last button and back to the first one pressing the First button. You may also move to a graph with a certain position within the results. Just type in the position number in the input field between the First and Last button and press Return.
If there are two or more matching subgraphs in the same corpus graph, the green navigation arrows in the Subgraph box on the right hand side of the navigation bar will be activated. Now you can navigate from one matching subgraph to the next using the green buttons. In the example screenshot, there are four NP subgraphs within the current corpus graph matching the query [cat="NP"].
The information box on the left shows the total number of matching corpus graphs and the total number of matching subgraphs within all corpus graphs. Thus, we have 176 corpus graphs which comprise at least one NP and 448 NPs in the whole corpus.
