The default configuration of the TIGERGraphViewer has been defined in such a way that the visualization should work fine on all supported platforms. If you like to adapt the configuration according to your individual preferences, you can modify the display colors and the most important display parameters. Your modifications are saved when leaving the tool and restored at the beginning of your next TIGERSearch session.
To change the color settings of the GraphViewer, please select the Color options item in the Options menu. The display color windows appers:
In this window all colors used by the TIGERGraphViewer are listed and illustrated by the color of the respective choose button. To change a color, press the corresponding Choose button. Another window pops up that lets you select the new color. Select the preferred color and leave this window by pressing the OK button.
If you would like to restore your configuration (that has been valid before opening the color options window), just click the Reset button. To restore the default values that have been pre-installed for using the TIGERGraphViewer activate the Default button. To leave the window without changing the configuration press the Cancel button. To submit your changes press the OK button.
Some important display parameters used by the TIGERGraphViewer can also be changed. To open the display options window, please select the Display options item in the Options menu. The display options window appers.
The following general parameters can be modified:
Maximum width of terminal nodes
The maximum width of the terminal node visualization is limited. Thus, some feature values (especially word forms) may be truncated. If this occurs too often, just specify a higher width.
Display secondary edges
In order to turn on/off the display of secondary edges check/uncheck this box.
Display virtual root node
Some corpus formats such as the Negra format do not integrate special types of tokens (e.g. punctuations marks) into the graph annotation. Unfortunately, the TIGERSearch query processing algorithm only works on connected graphs. Hence, during the indexing process a virtual root node is inserted in any graph that comprises terminal nodes (e.g. punctuations marks) which are not integrated into the corresponding syntax graph. In order to turn on/off displaying of virtual root nodes check/uncheck this box.
Sometimes annotating a token feature does not make sense for features such as morphological feature or case. In this case, a qualified symbol such as -- is used instead. We recommend you to use -- which is also used in our implemented import filters.
Since these symbols do not represent annotation information, it makes sense to hide them in the visualization. The two boxes must be checked if you want to hide a special feature value or edge label. Please specify the symbol which should be suppressed in the respective text fields.
The following corpus-depending parameters can be modified:
Displayed non-terminal feature
For non-terminal nodes, only one feature can be displayed in the GraphViewer. If there are two or more features defined for non-terminal nodes, the displayed feature can be changed in this dialog. By default, the non-terminal feature defined first in the TIGER-XML encoding is selected.
Displayed terminal features
By default, all features of the terminal nodes are displayed. If you like to reduce the number of displayed features, just deselect the features you are not ineterested in.
Please note: As these parameters are corpus-depending, they will be restored when the corpus is used again (even within the next TIGERSearch session).
If you like to restore your configuration (that has been valid before opening the display options window), just click the Reset button. To restore the original system defaults that have been pre-installed for using the TIGERGraphViewer activate the Default button. To leave the window without changing the configuration press the Cancel button. To submit your changes press the OK button.
